Abstract
Exposure of pesticides to wildlife species, especially on the aspect of endocrine disruption is of great concern. Wildlife species are more at risk to harmful exposures to the pesticides in their natural habitat through diet and several other means. Species at a higher tropic level in the food chain are more susceptible to the deleterious effects due to sequential biomagnifications of the pesticides/metabolites. Pesticides directly affect fitness of the species in the wild causing reproductive endocrine disruption impairing the hormones of the gonads and thyroid glands as reproduction is under the influence of cross regulations of these hormones. This review presents a comprehensive compilation of important literatures on the impact of the current use pesticides in disruption of both the hypothalamic-pituitary-gonadal and hypothalamic-pituitary-thyroid axes particularly in birds addressing impacts on the reproductive impairments and overall fitness. In addition to the epidemiological studies, laboratory investigations those provide supportive evidences of the probable mechanisms of disruption in the wild also have been incorporated in this review. To accurately predict the endocrine-disruption of the pesticides as well as to delineate the risk associated with potential cumulative effects, studies are to be more focused on the environmentally realistic exposure dose, mixture pesticide exposures and transgenerational effects. In addition, strategic screening/appropriate methodologies have to be developed to reveal the endocrine disruption potential of the contemporary use pesticides. Demand for adequate quantitative structure-activity relationships and insilico molecular docking studies for timely validation have been highlighted.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph191710486. [PMID: 36078202 PMCID: PMC9518406 DOI: 10.3390/ijerph191710486] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/27/2022] [Revised: 08/19/2022] [Accepted: 08/20/2022] [Indexed: 05/28/2023]
Abstract
Mancozeb (MNZ) is a fungicide commonly employed in many countries worldwide. This study assesses MNZ absorption dynamics in 19 greenhouse farmers, specifically following dermal exposure, aiming to verify the efficacy of both preventive actions and protective equipment. For data collection, a multi-assessment approach was used, which included a survey to record study population features. MNZ exposure was assessed through the indirect measurement of ethylene thiourea (ETU), widely employed as an MNZ biomarker. The ETU concentration was measured with the patch method, detecting environmental ETU trapped in filter paper pads, applied both on skin and working clothes, during the 8 h work shift. Urine and serum end-of-shift samples were also collected to measure ETU concentrations and well-known oxidative stress biomarkers, respectively, namely reactive oxygen metabolites (ROMs), advanced oxidation protein products (AOPPs), and biological antioxidant potential (BAP). It was observed that levels of ETU absorbed and ETU excreted were positively correlated. Additionally, working clothes effectively protected workers from MNZ exposure. Moreover, following stratification of the samples based on the specific working duty (i.e., preparation and spreading of MNZ and manipulation of MNZ-treated seedlings), it was found that the spreading group had higher ETU-related risk, despite lower chronic exposure levels. AOPP and ROM serum levels were higher in MNZ-exposed subjects compared with non-exposed controls, whereas BAP levels were significantly lower. Such results support an increase in the oxidative stress upon 8 h MNZ exposure at work. In particular, AOPP levels demonstrated a potential predictive role, as suggested by the contingency analysis results. Overall, this study, although conducted in a small group, confirms that ETU detection in pads, as well as in urine, might enable assessment of the risk associated with MNZ exposure in greenhouse workers. Additionally, the measurement of circulating oxidative stress biomarkers might help to stratify exposed workers based on their sensitivity to MNZ. Pivotally, the combination of both ETU measurement and biological monitoring might represent a novel valuable combined approach for risk assessment in farmhouse workers exposed to pesticides. In the future, these observations will help to implement effective preventive strategies in the workplace for workers at higher risk, including greenhouse farmers who are exposed to pesticides daily, as well as to clarify the occupational exposure levels to ETU.

Abstract
Acrylamide is an important industrial chemical; it also is formed in starch-rich foodstuffs during baking, frying and roasting. Most acrylamide exposure occurs by ingestion of processed foods. We investigated possible immunotoxic effects of extended administration of low doses of acrylamide in rats. To do this, we measured alpha-naphthyl acetate esterase (ANAE) and acid phosphatase (ACP-ase) activities in peripheral blood lymphocytes. Male and female weanling Wistar rats were administered 2 or 5 mg acrylamide/kg/day in drinking water for 90 days. Peripheral blood was sampled at the end of the administration period. We found ANAE staining in eosinophils and T-lymphocytes, but not in monocytes, platelets, B-lymphocytes and neutrophils. ACP-ase was found in B-lymphocytes. We found a significant reduction of the ratio of ANAE:ACP-ase in lymphocytes of the experimental animals compared to controls. We found no statistically significant differences between the doses or sexes. We found that acrylamide ingested in processed foods might affect the immune system adversely by decreasing the population of mature T- and B-lymphocytes.

Abstract
This study investigated the acute and single repeated dose effects of low concentrations of chlorpyrifos, diuron, and their mixture to chicken. The effects were determined as biological response (chicken behavior); physiological response (body weight, gaining weight); and biochemical response such as reduction of acetylcholine esterase activity (ACHE), changes in liver biomarkers, such as (1) alkaline phosphatase (ALP), (2) aspartate aminotransferase (AST), and (3) alanine aminotransferase (ALP), and effects on kidney biomarkers such as total protein, creatinine, uric acid, and urea. Results showed abnormal behavior on chicken received 5 μg/g and above from the tested compounds. A reduction in growth weight was observed in chicken received a single repeated dose of diuron and mixture. Enlargements in the liver and heart were observed in chicken received a single repeated dose of diuron. Percentage of serum ACHE inhibition increased linearly as the concentration of the tested compounds increased. The tested low concentration showed tremendous effects on liver enzymes and kidney functions. Similarly, a single repeated dose of the tested compounds caused severe inhibition on serum ACHE and affected the liver enzyme activities and kidney functions. It can be concluded that the low concentrations are not safe and may cause severe damage to the liver, heart, or kidney and disturb the life.

Abstract
Acrylamide (ACR), with high prevalence in starchy food, has been associated with the development of several organ toxicities such as immunotoxicity. This study aimed to demonstrate the role of oxidative stress and apoptosis as the mechanisms involved in ACR-induced immunotoxicity in mice. Mice were randomly assigned to six groups and treated as follows: control (normal saline), cyclophosphamide (200 mg kg–1), ACR groups (12.5, 25 and 50mg kg–1, orally), and l-carnitine (l-CAR; 100 mg kg–1) + ACR (50 mg kg–1). After 30 days of exposure, mice were killed and immunotoxic response was evaluated via immune blood cells count and body/organ weights. Oxidative stress parameters and pathological examination were done in thymus and spleen. Also, the apoptosis was evaluated via flow cytometric by annexin V/FITC kit in the splenocytes. Our results indicated that ACR could induce immunotoxicity characterized by reduction in immune blood cells, body/organ weights, and pathological changes in spleen. The assessment of oxidative stress markers revealed increase in lipid peroxidation, protein carbonyl content, and depletion of glutathione level. Also, increased apoptosis was observed in splenocytes after ACR administration compared to the control group. These alterations were markedly normalized by coadministration of l-CAR (as a potent antioxidant). Taken together, the results of this study showed the potential of ACR to induce immunotoxicity through provoking oxidative stress and inducing apoptosis and the protective effect of l-CAR to attenuate this toxicity. These findings will help in elucidating the toxicity mechanism induced by ACR.

Abstract
The immune system can be the target of many chemicals, with potentially severe adverse effects on the host's health. In the literature, carbamate (CM) pesticides have been implicated in the increasing prevalence of diseases associated with alterations of the immune response, such as hypersensitivity reactions, some autoimmune diseases and cancers. CMs may initiate, facilitate, or exacerbate pathological immune processes, resulting in immunotoxicity by induction of mutations in genes coding for immunoregulatory factors and modifying immune tolerance. In the present study, direct immunotoxicity, endocrine disruption and inhibition of esterases activities have been introduced as the main mechanisms of CMs-induced immune dysregulation. Moreover, the evidence on the relationship between CM pesticide exposure, dysregulation of the immune system and predisposition to different types of cancers, allergies, autoimmune and infectious diseases is criticized. In addition, in this review, we will discuss the relationship between immunotoxicity and cancer, and the advances made toward understanding the basis of cancer immune evasion.
