Abstract
OBJECTIVE Nail salons offer a developing and diverse occupation for many women, especially the new generation. Due to the increasing apprehension surrounding heavy metals in dust caused by filing nails containing dried nail polish, the present study was designed aimed to health risk assessment of heavy metals in breathing zone of nail salon technicians (NSTs). METHODS This is a cross-sectional study that was conducted in NSTs. The concentration of Cadmium (Cd), Lead (Pb), Nickel (Ni), Chromium (Cr) and Manganese (Mn)in breathing zone of 20 NSTs was determined using ICP-OES. RESULTS The metal concentrations were in the following order: Mn > Pb > Ni > Cr > Cd with corresponding arithmetic mean values of0.008, 0.0023, 0.0021, 0.001 and 0.0006 mg m-3, respectively, which are exceeded the recommended levels stated in the indoor air guidelines. The average lifetime carcinogenic risk (LCR) for Cr, Cd, Ni and Pb was calculated 0.0084, 0.00054, 0.00026 and 1.44 E - 05, respectively. The LCR values of all metals (except Pb) exceeded the acceptable level set by the USEPA. The mean of Hazard quotients (HQ) for Mn, Cd, Cr, Ni and Pb were calculated to be23.7, 4.74, 2.19, 0.51 and 0.0.24, respectively. The sensitivity analysis showed that, the exposure frequency (EF) for Cr and Ni had the strong effects on generation of both LCR and HQ. Furthermore, the concentrations of Mn, Cd and Pb had strong impacts on the HQ generation and the concentration of Cd and Pb had main effects on LCR generation. CONCLUSION To effectively reduce pollutant concentration, it is recommended to install a ventilation system near nail salon work tables and conduct continuous monitoring and quality control of nail products.

Abstract
In recent years, the nail industry has been widely popular in China, and the use of nail care products has also significantly increased. Due to its high content of volatile solvents, the released VOCs not only have a negative impact on indoor air quality but also pose a health threat to nail salon workers who are highly exposed to such environments. The objectives of this research were to characterize VOCs emissions from detailed manicure processes and to evaluate the impact on the environment and health risks. Results showed that the VOCs concentration in the anti-warping treatment process was much higher than that in other manicure steps, at 360.69 mg/m3, making its contributions of OFP and SOA equally prominent. The trend of concentration contribution was similar to that of OFP, and OVOCs were the most significant contributor to the VOCs components in the whole manicure process. Since organic solvent nail gels were also frequently used in most steps, the main VOCs were methanol, ethanol and ethyl acetate. Aromatics were the component that contributed the most to SOA, and its contributions in all processes were >85 %. Health risk assessments performed in our study indicated that acrolein was the main non-carcinogen, and the carcinogenic risk of this study could be ignored. The results of this study can be used as a basis for controlling VOCs emission and reducing exposure to VOCs in nail salons.

Abstract
Despite occupational exposure to hazardous chemicals in cosmetics and personal care products (PCPs), salon workers receive minimal formal protections. Consequently, most salon workers rely on personal safeguards. However, the nature of such individual-level safeguards remains unknown. Knowledge of risks associated with occupational use of cosmetics and PCPs and information needs of salon workers were investigated in Kisumu City, Kenya. Responses from 302 respondents showed that 84% were women and 30% had post-secondary education. Seventy percent reported knowing that ingestion, inhalation, dermal absorption, and injection are the pathways through which harmful products in cosmetics and PCPs may enter the body. Salon workers who had been employed for more than 5 years were at least twice more likely to report that it is not the case that cosmetics and PCPs only cause harm to children (5-10 years vs 1 year: OR = 2.440, 95% CI, 1.160-5.239; >10 years vs 1 year: OR = 8.857, 95% CI, 3.163-29.377); they were about three times more likely to either agree with the statement that cosmetics and PCPs only cause harm under prolonged exposure or to say that they did not know compared to their counterparts who had worked in the industry for 1 year (5-10 years vs 1 year: OR = 2.750, 95% CI, 1.144-7.179; >10 years vs 1 year: 3.179, 95% CI, 1.173-9.096). Over 50% of the respondents reported that they need information on how to protect themselves and others; on available protective measures; and on cosmetic products and PCPs that are safe. Sixty percent reported that they would prefer to get such information from the Ministry of Health at the county or national level and on product inserts. Overall, salon workers in Kisumu City are knowledgeable about the risks associated with their occupation but also appreciate gaps in their knowledge, which can be filled by government-mandated interventions.

Abstract
Asian and Asian Americans (A/AA) are a group overlooked in general health outcomes but especially occupational safety and health outcomes. In the United States, the beauty service microbusiness industry (e.g., nail salons) predominantly employs immigrant Asian women who regularly encounter a plethora of occupational hazards (e.g., harmful chemical exposures -toluene, formaldehyde, bloodborne pathogens, fungi. However, due to the precariousness of beauty service jobs, cultural and linguistic barriers, and social determinants of health, A/AA beauty service workers face complex occupational safety and health challenges that require interdisciplinary collaboration and cultural competency to address. This commentary will discuss a multi-level approach including specific outreach partners that will offer the required diverse skillsets necessary for improving the occupational safety and health for this worker population in this microbusiness industry. Implications and suggestions for interventions and policy changes are also recommended utilizing the National Institute on Minority Health and Health Disparities' Research Framework.

Abstract
Back pain and neck pain are important public health concerns and are among the most common and disabling conditions globally. However, the relationships among indoor air quality (IAQ), breathing parameters (pulmonary function, respiratory disorders), and back pain and neck pain have not been adequately assessed. The purpose of this study was to systematically review the literature about the impact of IAQ and breathing parameters on back pain and neck pain (PROSPERO ID: CRD42022380515). CINAHL, EMBASE, PEDRo, and PubMed databases were searched through January 19, 2023. Inclusion criteria for study eligibility were observational studies (except case reports) or randomized controlled trials (RCTs), published in peer-reviewed journals in the English language, human research, original research, examined the relationships between IAQ, or breathing parameters with back pain or neck pain. Review procedures were conducted and reported according to PRISMA recommendations. Empirical evidence statements were developed for observational studies, and grades of evidence statements were developed for RCTs. Sixty-seven eligible studies were found (54 observational studies and 13 RCTs) that enrolled 345,832 participants. None of the studies assessed the combined impact of IAQ and breathing parameters on back pain or neck pain. No level 1 studies were found, which precludes making strong statements about causality and strong recommendations about the efficacy of IAQ and breathing exercise interventions for reducing pain and disability related to back pain and neck pain. Evidence indicates that poor IAQ and respiratory disorders are related to an increased risk of back pain and neck pain. Conflicting evidence exists about the association between pulmonary function with back pain and neck pain. Evidence for breathing exercise interventions was mixed with numerous limitations. This review provides preliminary evidence on the relationships of IAQ and breathing parameters with back pain and neck pain, which can be used to guide future research and clinical implementation efforts. Assuming positive findings in subsequent research, a wide range of stakeholders involved with this complex human-building-environment interface can be equipped to address IAQ and breathing parameters, along with other established risk factors to help those suffering from back pain and neck pain.

Abstract
The nail salon industry has grown considerably, but there are serious concerns about the health risks associated with working in this field. Therefore, the purpose of this study was to investigate the exposure of nail technicians to BTEX. A cross-sectional study was conducted on 49 salons, and NIOSH Method 1501 was used to measure the concentration of BTEX in the breathing zone of technicians. The EPA method was used to assess health risks. Statistical analysis was conducted using SPSS software. The mean concentrations of toluene were (82.65 ± 198.84µg/m3)µg/m3, followed by benzene (10.58 ± 9.62µg/m3), p-xylenes (20.77 ± 37.79µg/m3), o-xylene (13.79 ± 25.70µg/m3), and ethylbenzene (29.35 ± 58.26µg/m3) , that lower than the permissible exposure limits suggested by NIOSH. Among the BTEX, toluene (82.65 ± 198.84µg/m3) has the most concentration in the nail salons. It was also discovered through multiple linear regression analysis that humidity had a significant effect on increasing the concentration of toluene (Beta = 0.50, P-value = 0.001) and ethylbenzene (Beta = 0.16, P = 0.049), while there was a considerable association between the number of services performed and benzene concentration (Beta = 0.34, P = 0.010). The average inhalation lifetime cancer risk for benzene (4.9 × 10 -5±4.5 × 10-5) was higher than the recommended value set by the US EPA. Although the concentrations of BTEX were lower than the maximum permissible limits, the results of the cancer risk assessment for benzene showed that working in nail salons with poor ventilation is hazardous. Therefore, exposure can be minimized by ensuring appropriate ventilation in the workplace and using safe products.

Abstract
Nail technicians are exposed to volatile organic compounds (VOCs) emitted from nail products used in their daily work, which may cause adverse health effects. This study aimed to assess VOC exposure of nail technicians in the South African formal and informal sectors and to provide a task-based exposure assessment of different nail applications. Personal passive sampling was conducted on 10 formal and 10 informal nail technicians located in the northern suburbs of Johannesburg and the Braamfontein area, over 3 days. Real-time measurements were taken to determine task-based peak exposures. The number of clients serviced, working hours, type of nail application, type of ventilation, room volume, and carbon dioxide (CO2) concentrations, were also recorded. There were differences in the nail products used, the types of nail applications performed, the number of clients serviced, and breathing zones VOC concentrations of the formal and informal nail technicians. Some formal nail salons were equipped with mechanical ventilation while the informal nail salons relied on natural ventilation. CO2 concentrations were higher in the informal than the formal nail salons and increased during the course of the working day. Formal nail technicians were exposed to higher total volatile organic compounds (TVOC) concentrations than informal nail technicians, which may be due to the different nail application procedures as well as 'background' emissions from their co-workers-the bystander effect. Acetone was the predominantly detected VOC: the formal nail technicians were exposed to significantly higher TWA (8 h) concentrations [geometric mean (GM) 43.8 ppm, geometric standard deviation (GSD) 2.49] than were the informal nail technicians (GM 9.87 ppm, GSD 5.13). Methyl methacrylate among the informal nail technicians was measured at 89.7% detection frequency, far higher than that among the formal nail technicians (3.4%). This may be attributed to the observed popularity of acrylic nail applications in this sector. Nail applications involving soak-off gave rise to high TVOC peaks at the start of the nail application process. This is the first study to compare organic solvent exposures among formal and informal nail technicians and determine task-based peak exposures. It also brings attention to the often-overlooked informal sector of this industry.

Abstract
BACKGROUND: The nail job is a new occupation in which the number of people who choose this job is rising. Therefore, the harmful hazards affecting the health of the practitioners should be taken into account. OBJECTIVE: The purpose of this study is to evaluate the ergonomics and occupational health hazards among nail technicians in Iranian society. METHODS: The self-administered questionnaire, the Nordic Musculoskeletal Questionnaire and Novel Ergonomic Postural Assessment (NERPA) method were used to gather data from 80 female nail technicians who participated in this study. RESULTS: More than half of the participants (67.6%) complained of coughing and eye irritation (70%) which was the most frequently reported irritation. The final score of the NERPA was at a high-risk level and the neck pain (63.8%) was the highest in comparison with other parts of the body. There was a significant relationship between activity type with disorder in the neck, elbow, hip, knee, and ankle. Lighting intensity was not significantly associated with musculoskeletal disorders. CONCLUSIONS: Concerning the low work experience, the prevalence of musculoskeletal disorders and, respiratory complaints is high. Hence, the attention of policy-makers to the safety and hygiene issues of women in this occupation is necessary by setting guidelines and considering inspections of occupational health and safety professionals.

Abstract
Background Nail salon workers (NSW) in the United States (U.S.) are predominantly immigrant women who face a number of occupational hazards, such as biological, ergonomic, and chronic chemical exposures. Additionally, there are challenges to keeping up with the latest practices in this evolving small business industry. Licensure requirements are intended to keep not only consumers but also workers safe, however licensure requirements vary between states creating little skill, education, and occupational health and safety knowledge and practice consistency among the nail salon workforce. The current state of nail salons and licensure of workers in the State of Michigan—an overlooked state and region (Midwest) in NSW research—was determined to better characterize this workforce. Methods A Freedom of Information Act request was submitted to the Michigan Department of Licensing and Regulatory Affairs regarding nail salon establishments and their workers, formally termed manicurists, and citation data for breaches. Data were provided on the number of licensed cosmetologists and cosmetology businesses from January 2017 to March 2021. From there, the total number of licensed manicurists was determined, and the cosmetology establishment list was analyzed to see if the businesses exclusively or predominantly provided nail services. Results As of Mach 2021, there were 1372 nail salons that exclusively provided nail services and over 12,000 licensed manicurists. Over half of the disciplinary actions cited were for salons not officially licensed. Michigan has reduced licensure requirements compared to other states and no continuing education (CE) requirements for license renewals. Conclusion There is a need for industry educational and training standardization, across the nation, as well as heightened licensure requirements for these vulnerable workers. CE not only keeps workers abreast of the latest practices in the industry, but also provides them the skills and knowledge to enhance their worker health, safety, and wellbeing.

Abstract
OBJECTIVES Nail workers are exposed to many hazardous chemicals. Despite many warnings about health problems among nail workers in other countries, data concerning exposure to chemical hazards among nail workers is still limited in Vietnam. In this study, we aimed to identify exposure to volatile organic compounds and their relationship with occupational symptoms among Vietnamese female nail salon workers. METHODS A cross-sectional study was conducted in Danang, Vietnam, from January 2019 to September 2019. Total 42 personal passive samplers were collected to evaluate 12 substances from 21 nail workers (15 salons) twice a week. We chose one representative worker from each of the nine salons with less than six workers and two representative workers from each of the six salons with over five workers for personal sampling based on the principle of similar exposure groups. We interviewed a total of 100 nail workers in 15 salons and 100 office workers in offices adjacent to the salons to compare occupational symptoms among them. RESULTS The commonly detected compounds in nail salons were acetone (97.6%), butyl acetate (83.3%), and ethyl acetate and ethyl methacrylate (78%). The concentration of total target VOCs was related to the number of serviced customers, the concentration of CO2 , and general ventilation used. The subjective symptoms were significantly higher for the nail workers than for the comparison subjects, that is, headache, nausea, nose irritation, skin irritation, shortness of breath, and confusion. Among 100 nail workers, nose irritation was significantly higher for nail workers who were exposed to acetone at levels exceeding the Vietnam occupational exposure limit (VOEL) adjusted with the Brief-Scala model. CONCLUSIONS Exposure to VOCs such as acetone in nail salons results in occupational symptoms among workers.

Abstract
OBJECTIVES The nail salon industry has seen significant growth in recent years. Nail technicians provide manicures, pedicures and apply artificial nails; tasks that expose them to chemicals, including acrylates that are known skin and respiratory sensitizers. This paper reports on potential skin exposure to acrylates among nail technicians in Toronto, Canada. METHODS Hand skin wipes were collected after (i) the application of artificial nails, (ii) the application of ultraviolet cured gel nail polish, and (iii) deliberate contact with nail polish. Surface wipes were collected from work areas and surfaces contaminated with known products. Wipe samples were analysed for eight acrylates: methyl acrylate (MA), ethyl acrylate (EA), methyl methacrylate (MMA), ethyl methacrylate (EMA), 2-hydroxyethyl acrylate (HEA), 2-hydroxyethyl methacrylate (HEMA), 2-hydroxypropyl methacrylate (HPMA), and ethylene glycol dimethacrylate (EGDMA) by gas chromatography with mass spectrometry. RESULTS Thirty-five wipe samples were collected. No acrylates were detected in skin samples (n = 8) or work surfaces (n = 6). However, MMA, EMA, EA, HEMA, and HPMA were detected in the samples of surfaces contaminated with known products. MMA was detected in 28% of products tested. HEMA and HPMA were detected where deliberate contact with nail polish occurred. CONCLUSIONS These results confirm that acrylates are present in nail products. However, no acrylates were detected in skin wipes. MMA, a chemical prohibited for use in cosmetics in Canada, was detected in nail polishes. Nail technicians should continue to employ safe work practices that reduce the probability of skin contact with acrylates and other chemicals.

Abstract
OBJECTIVES In recent years, nail salons have become more abundant than ever. The majority are small businesses, often employing immigrant women. Nail technicians have many exposures at work including chemical, biological, physical, and ergonomic hazards but few data exist on their symptoms or occupational health and safety practices, particularly in the Canadian context. The aim of this study was to learn about nail technicians, their work, and their health and safety practices. METHODS Nail technicians were recruited from nail salons in Toronto, Ontario. Participants completed an anonymous survey with questions about demographics, work tasks, workplace health and safety practices, and symptoms (skin, respiratory, and musculoskeletal). RESULTS A total of 155 nail technicians (95% female) participated in the survey. The majority of nail technicians performed manicures (99%) and pedicures (96%) and applied shellac polishes (86%). Only a third (34%) applied acrylic artificial nails. The reported use of personal protective equipment (PPE) was very high; 88% reported using a mask at work and 96% reporting using gloves. The most common symptoms reported by technicians were neck (44%) and back pain (38%). Skin and respiratory symptoms were less common with 6% of technicians reporting cough, 8% wheeze, and 5% a current rash. Technicians working over 30 h per week reported more neck pain (52 vs. 32%, P = 0.02). Technicians who reported using shellac polishes were more likely to report a runny nose (25 vs. 0%, P = 0.01). CONCLUSIONS Nail technicians in Toronto, Canada are experiencing work-related symptoms. Musculoskeletal symptoms were the most common symptoms reported. Much of the focus on nail salons and health has been on chemical exposures, but ergonomic hazards should not be overlooked. Efforts to increase knowledge and improve occupational health in nail salons should include information on multiple possible workplace hazards and how to reduce impacts of exposure.

Abstract
Volatile organic compounds (VOCs) are commonly found in consumer products, including furniture, sealants and paints. Thus, indoor VOCs have become a public health concern, especially in high-income countries (HICs), where people spend most of their time indoors, and indoor and outdoor air exchange is minimal due to a lack of ventilation. VOCs produce high levels of reaction with the airway epithelium and mucosa membrane and is linked with pulmonary diseases. This paper takes a stock of the literature to assess the strength of association (measured by effect size) between VOCs and pulmonary diseases with the focus on asthma and its related symptoms by conducting a meta-analysis. The literature was searched using the PubMed database. A total of 49 studies that measured VOCs or VOC types and pulmonary health outcomes were included in the analysis. The results of these studies were tabulated, and standard effect size of each study was computed. Most studies were conducted in high-income countries, including France (n = 7), Japan (n = 7) and the United States (n = 6). Our analysis suggests that VOCs have a medium-sized effect on pulmonary diseases, including the onset of asthma (effect size (or Cohen's d) ~0.37; 95% confidence interval (CI) = 0.25-0.49; n = 23) and wheezing (effective size ~0.26; 95% CI = 0.10-0.42; n = 10). The effect size also varied by country, age and disease type. Multiple stakeholders must be engaged in strategies to mitigate and manage VOC exposure and its associated pulmonary disease burden.

Abstract
PURPOSE Nail technicians (NTs) are exposed to a low-level mixture of volatile organic solvents (VOCs), yet the health hazards related to such exposure are unknown. This study thus aimed to compare the blood plasma levels of selected biomarkers related to liver status and lipid profile among occupationally exposed NTs and unexposed controls. Associations between out-of-normal-range levels of such biomarkers and occupational exposure to VOCs mixture have also been investigated. METHODS The study enrolled 145 female NTs and 152 unexposed controls. Biochemical analyses were performed using spectrophotometric assays and obtained data were analyzed using general linear model and Poisson regression modelling adjusted to multiple confounders. RESULTS Compared to controls, NTs presented significantly increased plasma activities of ALT (2.04 ± 0.63 ln-U/l vs. 1.25 ± 0.71 ln-U/l; p < 0.0001) and AST (2.73 ± 0.25 ln-U/l vs. 2.08 ± 0.95 ln-U/l; p < 0.0001), and significantly increased plasma levels of TG (4.38 ± 0.53 ln-mg/dl vs. 4.21 ± 0.42 ln-mg/dl; p < 0.05) and TC/HDL ratio (1.18 ± 0.36 vs. 1.02 ± 0.27; p < 0.0005). Plasma levels of HDL were significantly lower among NTs (4.02 ± 0.29 ln-mg/dl vs. 4.21 ± 0.26 ln-mg/dl; p < 0.0001). Moreover, NTs were found to present significantly increased risk of occurrence of clinically relevant plasma HDL levels below 3.91 ln-mg/dl (i.e., 50 mg/dl; RR = 1.58, 95% CI 1.07-2.32, p < 0.05), as well as increased risk of clinically relevant TC/HDL ratio above the normal range limit of 3.5 (RR = 1.68, 95% CI 1.19-2.35, p < 0.005), as compared to unexposed controls. CONCLUSION Nail technicians are subject to adverse changes in selected plasma biomarkers related to liver functions, some of which may be of clinical relevance.

Abstract
OBJECTIVES Beauty is a Lebanese stereotype, as Lebanese women often feel urged to decorate themselves. Recent studies have raised concerns about nail salon technicians' (NSTs) health and safety issues. The aim of our study was to evaluate the occupational symptoms reported by NSTs, to assess their knowledge and document their awareness regarding hazardous chemicals found in nail cosmetics. METHODS NSTs completed a researcher-administered questionnaire. Data were gathered on sociodemographic characteristics, perceived knowledge, and safety issues. Work-related symptoms reported by NSTs were evaluated, and their responses were compared to those of the office employees. RESULTS A total of 120 NSTs and 120 office employees were interviewed. Compared to the control group, NSTs reported a higher prevalence of work-related respiratory, dermal, and irritative symptoms, all significantly associated with smoking and a poor ventilation system. In addition, musculoskeletal complaints were common among NSTs and significantly linked to a poor ventilation system, an increased number of customers per day, and a longer service duration. Furthermore, a longer career duration was significantly associated with an increased prevalence of irritative symptoms. When a binary logistic regression was carried out, it demonstrated a 25 times higher prevalence of work-related symptoms among NSTs compared to the office employees. Interestingly, 84% of the respondents had an inaccurate knowledge of nail cosmetics' risks with their educational level acting as key factor. CONCLUSIONS Based on these findings, it is warranted to perform a clinical assessment, implement a stringent regulatory framework, and improve knowledge toward nail cosmetics' risk.

Abstract
The products used in nail care services contain toxic chemicals. This study aimed to characterize occupational health risk factors and chemical exposures among Asian nail salon workers on the East Coast of the U.S. for informing the development of more effective, culturally appropriate interventions. We conducted a community-based participatory research (CBPR) study to characterize occupational health risks. A face-to-face, self-reported survey was performed, and personal exposure to volatile organic compounds (VOCs) was evaluated. Three VOCs, acetone, methyl methacrylate (MMA), and toluene, were measured using 3M 3500 organic vapor monitors. We collected data on 112 workers with 100 personal chemical exposure measurements from 25 nail salons. Self-reported health problems that emerged or worsened after participants started working in the nail salon industry included headaches (8%); lightheadedness (9.8%); and irritation to the nose, eyes, throat, and skin (21.2%). Approximately 70% of participants reported that they had been pregnant, 11.7% of whom had at least one miscarriage. The mean concentrations of acetone, MMA, and toluene were 18.51 parts per million (ppm), 39.45 ppm, and 0.09 ppm, respectively. Mean concentrations of acetone and MMA measured from salons in New York City were significantly lower than those measured in Philadelphia and southern New Jersey. CBPR proved to be as an efficient approach for recruiting hard-to-reach Asian immigrant nail salon workers. Adverse health symptoms and problems associated with providing nail salon services were identified in these workers. Further studies are needed to better understand the long-term health effects of chronic chemical exposures in nail salon environments.

Abstract
Abstract
In 2015, New York State enacted new ventilation regulations to protect employees and clients from exposure to chemicals used in nail salons. This study measured common air pollutants found in nail salons and assessed compliance with ventilation requirements. Area sampling was conducted in 12 nail salons located in New York City for three consecutive days (Thursday, Friday, and Saturday) to measure total volatile organic compounds (TVOCs), methyl methacrylate, toluene, and ethyl acetate concentrations and estimate ventilation rates. Salon characteristics were determined through a walkthrough inspection and survey administered to the manager. The average daily concentration of carbon dioxide and TVOCs across all salons was 1070 ppm [standard deviation (SD) = 440 ppm] and 29 ppm (SD = 25 ppm), respectively. Chemical-specific air sampling showed low to non-detectable levels of the three measured chemicals. Seventy-five percent of the nail salons did not meet general minimum outdoor airflow requirements. Little temporal variation was observed in day-to-day average concentrations of contaminants within salons, indicating uniform exposure during high customer count days. Salons that met the outdoor airflow requirements had twice the average daily customers (83 versus 42) and half the TVOC concentrations compared with salons that did not (33 versus 16 ppm). Nail salons not meeting ventilation requirements tended to have fewer customers and managers that did not understand the essential components of the ventilation system. Data from this study can be used as evidence of reduction in exposure due to compliance with the ventilation requirements.

Abstract
OBJECTIVE This cross-sectional field study evaluated potential associations between acute symptoms among nail technicians and exposure of chemical hazards in New Jersey salons. METHODS In 2016, an in-person safety and health survey was conducted. Data were gathered on symptoms, demographics, work history, tobacco use, area and/or task ventilation, use of personal protective equipment, and safety training. Workplace hazards were identified by observational survey during site visit walk-throughs. RESULTS Of the 68 respondents from 40 participating salons whose owners agreed to participate (35% salon-level participation), most were Asian females with a self-reported history of work-associated eye, nose, throat, and skin symptoms. Few workers used personal protective equipment. Most workers had not received training in their primary language. CONCLUSIONS Nail salon workers need comprehensive chemical use training. More research is needed to determine extent of exposure.

Abstract
Several manufacturers are producing disposable dual-use dust masks that are primarily designed to protect against airborne particulate exposures but that also contain a layer of activated carbon to provide protection against organic vapors (OVs) at levels below permissible exposure levels, referred to as "nuisance level" by the FFR manufacturers. Industries identified in the literature as commonly having employees exposed to nuisance-level OVs include beautician salons, dry cleaning operations, and pesticide applications. This study investigated the adsorption capabilities of three different dual-use dust masks that contain both filter media to remove particles and activated carbon to capture OVs. The three dual-use dust masks were tested and compared relative to the 50% breakthrough time for two OVs (acetone and perchloroethylene) and one non-carbon-based contaminant gas (ammonia) often found in agricultural settings at nuisance-level amounts. The dual-use dust masks were exposed to 15 ppm and 50 ppm for all 3 compounds, which represented the range of nuisance-level exposure documented in literature. Most tests were conducted at 21 °C and 50% relative humidity. A relative humidity level of 95% was also created to compare results under that condition. The non-approved dual-use dust masks were ineffective for all vapors and offered less than 10 min of protection before 50% breakthrough occurred. All dual-use dust masks performed poorly when exposed to ammonia, with breakthrough time less than 7 min at 50 ppm and 10 min at 15 ppm. The approved dual-use dust mask had 50% breakthrough times, for example, of 121 min and 233 min for acetone at 15 ppm and 50 ppm, respectively. The less volatile perchloroethylene took over 400 min to achieve 50% breakthrough at 50 ppm. High relative humidity reduced breakthrough times by up to 70%. These results indicate high variability in performance among dual-use dust masks. Performance is also dependent on gas/vapor volatility and levels of water vapor. However, one model tested, the 3M model 8514, did show promise as an acceptable method for greatly reducing nuisance-level OV exposures.

Abstract
Nail technicians are exposed to volatile organic compounds (VOCs) from nail products, but no studies have previously measured VOC biomarkers for these workers. This study of 10 nail technicians aimed to identify VOCs in nail salons and explore relationships between air concentrations and biomarkers. Personal and area air samples were collected using thermal desorption tubes during a work shift and analyzed using gas chromatography/mass spectrometry (GC/MS) for 71 VOCs. Whole blood samples were collected pre-shift and post-shift, and analyzed using GC/MS for 43 VOCs. Ventilation rates were determined using continuous CO2 measurements. Predominant air VOC levels were ethyl methacrylate (median 240 µg/m3 ), methyl methacrylate (median 205 µg/m3 ), toluene (median 100 µg/m3 ), and ethyl acetate (median 639 µg/m3 ). Blood levels were significantly higher post-shift than pre-shift for toluene (median pre-shift 0.158 µg/L and post-shift 0.360 µg/L) and ethyl acetate (median pre-shift <0.158 µg/L and post-shift 0.510 µg/L); methacrylates were not measured in blood because of their instability. Based on VOCs measured in these seven nail salons, we estimated that emissions from Greater Boston area nail salons may contribute to ambient VOCs. Ventilation rates did not always meet the ASHRAE guideline for nail salons. There is a need for changes in nail product formulation and better ventilation to reduce VOC occupational exposures.

Abstract
Globally, nail salons represent a fast expanding industry and often with low-income cosmeticians. In general, cosmeticians have limited access to safety information about the hazardous materials they handle, which would potentially enable them to minimize workplace exposures. The problem is much pronounced in low- and middle-income countries due to weaknesses in regulation of the industry. We investigated determinants of exposures to hazardous materials among nail cosmeticians in Kampala District, Uganda. We employed a cross-sectional study design among a random sample of 243 participants. The sociodemographic characteristics, education and training status, knowledge about routes of exposure to hazardous chemicals, and personal protective material use of cosmeticians were assessed through face-to-face interviews. Most cosmeticians were aged 18–34 years, and more males were engaged in this work than females. Also, 82.7% believed inhalation was the major exposure route for the chemicals they handled. Participants who had attained secondary-level education and above were over three times more likely to wear masks (AOR = 3.19, 95% CI 1.58–6.41) and gloves (AOR = 3.48, 95% CI 1.55–7.81) and over two times more likely to use aprons (AOR = 2.50, 95% CI 1.18–5.32). Participants who had ever received safety training on hazardous chemicals were more likely to wear all four personal protective equipment: masks (AOR = 3.21, 95% CI 1.61–6.42), gloves (AOR = 4.23, 95% CI 2.05–8.75), goggles (AOR = 4.14, 95% CI 1.25–13.65), and aprons (AOR = 2.73, 95% CI 1.25–5.96). Participants who had spent more than two years in the nail cosmetics business were more likely to wear masks (AOR = 3.37, 95% CI 1.64–6.95). With the increasing demand for nail cosmetics, and many people in urban areas of low-income countries engaging in this industry, there is need for training and better workplace policies to promote a healthier urban workforce dealing in cosmetics.

Abstract
Public concern regarding the use of products with chemicals has increased in Korea, following reports indicating that hazardous chemicals in products, such as disinfectants, can cause fatal lung disease. Despite the widespread use of car colorant products, little is known regarding their potential health risks. The purpose of this study was to determine the potential health risks of substances that exist in car colorant products. Thirteen car colorant products were purchased from the Korean market and 15 commonly used chemicals were analyzed. Exposure and risk assessments were conducted in two assessment stages (screening and refined). The analysis showed that all of the examined products contained toluene, ethylbenzene, and xylene. The maximum concentration of toluene was 52.5%, with a median concentration of 10.8%. Tier 1 (screening) assessment showed that four chemicals (toluene, ethylbenzene, xylene, and 2-butoxyethanol) may pose health risks, but tier 2 (refined) assessment showed that these chemicals do not pose any risk. However, these chemicals were present in all of the examined products, and government regulations did not control their concentrations in these products. Therefore, we suggest that levels of toluene, ethylbenzene, and xylene in car colorant products should be regulated to protect public health.

Abstract
In the United States, there are more than 120,000 nail salons in which workers could be potentially exposed to a number of volatile organic compounds (VOCs) used in various procedures. Measuring workers exposure in the field is time-consuming and could be very expensive. The purpose of this study was to estimate the VOC levels in the proximity of workers in nail salons through simulating the application process of some popular nail polishes in a laboratory chamber. The worst-case scenario was defined as a worker's exposure during nail polish application to one set of fingernails every 15 minutes for an 8-hour shift (total nail sets = 32). Nail polish was applied on paper plates in a flow-controlled test chamber. Air was sampled during the application of five different nail polishes for 8 hours using passive air samplers and the experiment was triplicated. Passive samplers were used for VOCs and formaldehyde. In this worst-case scenario setting, a total of 17 VOCs were detected, with eight that were found in all the samples. The mean concentration of butyl acetate (161-330 ppm, parts per million) and ethyl acetate (440 ppm) exceeded the threshold limit value (TLV) of 150 ppm and 400 ppm, respectively. Formaldehyde was analyzed separately and the mean concentrations exceeded the TLV of 0.10 ppm in all types of nail polish, ranging from 0.12 ppm to 0.22 ppm. Occupational safety and health professionals could use these data to increase awareness of workers' potential exposure to high levels of VOCs in nail salons and recommend practical measures to reduce potential exposures.

Abstract
BACKGROUND Chemicals in nail products have been linked to numerous health concerns. METHODS We recruited Vietnamese-American nail salon owners and workers in California and randomized salons into an intervention or control group. Owners in the intervention group received training and then provided education to workers in their salons on best practices to reduce workplace chemical exposures. Methyl methacrylate (MMA), toluene, and total volatile organic compounds (TVOCs) were measured using personal air monitors worn by workers during the work-shift. RESULTS We enrolled 77 salons (37 intervention and 40 control) and 200 workers. There was no significant intervention effect between the two groups. However, MMA and TVOCs were higher for workers who used gel polish and acrylic nails as well as in busy salons. CONCLUSIONS Although the intervention did not show reductions in chemical levels, identifying worker tasks and salon characteristics that predict chemical levels can inform future interventions to reduce exposures.

Abstract
Over the past several decades, the commercialization of nail cosmetics has increased. From nail polishes to artificial nails, different methods of nail beautification have become popularized. However, the impact of these products remains largely unknown. Governments have passed legislation in attempts to regulate nail cosmetics, but these regulations may not be adequate and are difficult to enforce. Knowledge of the safety and efficacy of nail products remains limited due to the relative dearth of literature published on the topic. This review serves to summarize and interpret the data available regarding common nail products and their safety and efficacy. Nail products such as nail polish, nail polish removers, and artificial nails have shown to have some adverse effects through case reports and studies. Harmful substances such as toluenesulfonamide-formaldehyde resin and methacrylates have been identified in commercial nail products, leading to several adverse effects, but in particular, allergic contact dermatitis. Exposure to substances such as acetonitrile found in removers may have more toxic and caustic effects, especially if ingested. In addition, for nail technicians there are negative effects linked with occupational exposure. Compounds used in nail products may become aerosolized and lead to asthma, eye and throat irritation, and even neurocognitive changes.

Abstract
Objectives: Nail salon owners in New York City (NYC) are required to provide their workers with gloves and it is their responsibility to maintain healthy, safe working spaces for their employees. The purpose of this study was to determine the frequency with which nail salon workers wear protective gloves. Methods: A Freedom of Information Law request was submitted to New York Department of State’s Division of Licensing Services for a full list of nail salons in Manhattan, NYC. A sample population of 800 nail salons was identified and a simple random sample (without replacement) of 30% (n=240) was selected using a random number generator. Researchers visited each nail salon from October to December of 2015, posing as a potential customer to determine if nail salon workers were wearing gloves. Results: Among the 169 salons in which one or more workers was observed providing services, a total of 562 workers were observed. For 149 salons, in which one or more worker was observed providing services, none of the workers were wearing gloves. In contrast, in six of the salons observed, in which one or more workers was providing services, all of the workers (1 in 2 sites, 2 in 1 site, 3 in 2 sites, and 4 in 1 site) were wearing gloves. Almost three-quarters of the total number of workers observed (n=415, 73.8%) were not wearing gloves. Conclusions: The findings of this study indicate that, despite recent media attention and legislation, the majority of nail salon workers we observed were not wearing protective gloves when providing services.

Does the Low-level occupational exposure to volatile organic compounds alter the seasonal variation of selected markers of oxidative stress? A case-control study in nail technicians.

Abstract
Background In this study we tested whether the seasonal variations in levels of selected biomarkers of oxidative stress in female nail technicians occupationally exposed to low levels of volatile organic compounds (VOCs) differ significantly from those observed among healthy unexposed controls. Airborne levels of selected VOCs in nail salons were also analyzed and tested for associations with seasonal variations of the levels of biomarkers among nail technicians. Methods The study enrolled 145 female nail technicians and 145 healthy unexposed female controls. The airborne VOCs and levels of biomarkers were assessed by GC-MS chromatography and absorption/fluorescence spectrophotometry, respectively. Results Plasma levels of thiobarbituric acid reactive species, ceruloplasmin, the activity of glutathione peroxidase (GPx1) and the SOD1/GPx1 activity ratio presented significant differences between the so-called “hot” and “cold” seasons in the case of nail technicians as well as in unexposed controls (p < <0.0001 for all four biomarkers). The pattern of these variations among nail technicians was found to be significantly different compared to that of the control subjects (p < <0.0001). Although such differences might intuitively be attributed to occupational exposure of nail technicians to VOCs, which was found to be higher during the “cold” season compared to the “hot” one, our study provided only limited evidence in favor of the hypothesis, that the different pattern of seasonal variations of biomarkers among nail technicians might have resulted from seasonal fluctuations in their occupational exposure to VOCs. Conclusion Further investigation is thus needed in order to elucidate the effect of low-level occupational exposure to VOCs on seasonal variations of biomarkers of oxidative stress.
