The role of adipose tissue analysis on Environmental Pollutants Biomonitoring in women: The European scenario. THE SCIENCE OF THE TOTAL ENVIRONMENT 2022; 806:150922. [PMID: 34655625 DOI: 10.1016/j.scitotenv.2021.150922] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/25/2021] [Revised: 09/24/2021] [Accepted: 10/07/2021] [Indexed: 06/13/2023]
Abstract
Humans are exposed every day to assorted environmental pollutants namely, polychlorinated biphenyls (PCB), organochlorine pesticides (OCP), brominated flame-retardants (BFR), polycyclic aromatic hydrocarbons (PAH), synthetic musks, heavy metals (e.g. cadmium) and plastic additives (e.g. bisphenol A, BPA). Besides environmental persistence, biomagnification and bioaccumulative properties, these pollutants are classified as endocrine disruptors (EDs), metabolic disruptors, neurologic disruptors. These compounds affect the normal function of several mechanisms in the human body being linked to human health issues as cancer development (e.g. breast, uterine and endometrial), miscarriage, birth defects, premature delivery and infertility. In order to prevent future health issue of women and possible progeny, the assessment of EDs accumulated is essential, particularly in adipose tissue. These samples have been referred as the ideal matrix to establish over time accumulation and long-term exposure of persistent and non-persistent lipophilic EDs. However, the invasive sample collection procedure and methodology processing discourages the usage of this matrix for biomonitoring studies. In this review, a Web of Science search without any publishing year restriction on the analysis in adipose tissue of PCB, OCP, BPA, cadmium, BFR and synthetic musks was performed. A total of 313 studies were found, 158 were European studies from which the studies with data on women EDs accumulation were selected for detailed analysis (n = 90). The results were structured and presented in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The present paper is an overview on the existent EDs analytical methods and levels accumulated in women adipose tissue, with the correspondent health implications across Europe. The limits of detection and quantification were compared and a discussion with results obtained about the presence of ED was performed.

Abstract
The storage levels of DDT and its metabolites, following the long term administration of technical DDT at the dose levels of 2, 20, 50 and 250 ppm to mice, were evaluated in the fat tissue, liver, kidney, brain and reproductive organs. In addition, storage levels were evaluated in foetuses and newborns of DDT-treated mothers. Apart from op'-DDT, there was a direct relationship between the concentration of each metabolite in each organ and the dose to which the animal was exposed. The highest concentration of DDT and metabolites was found in the fat tissue followed by reproductive organs, liver and kidney together, and lastly brain. The most prevalent metabolite was pp'-DDT, except in the liver, where pp'-DDD showed the highest concentration. Pregnant females had lower concentrations of all metabolites than non-pregnant females. The concentration of residues in samples of total foetal litters was directly related to the concentration of DDT fed to the mother. There was a strong negative correlation between the concentration of pp'-DDT and that of pp'-DDD in the foetuses and the placentas of the same litter. A significant increase in whole body DDT concentration was observed shortly after birth.

Abstract
Despite considerable concern regarding the effects on reproductive outcome of exposures to pesticides, convincing evidence for the developmental toxicity of occupational and environmental pesticide exposure in humans is lacking. In this comprehensive review of the English language epidemiologic literature, we summarize studies that have examined potential associations between fetal deaths (both spontaneous abortions and stillbirths) and specific pesticides, as well as maternal and paternal employment in occupations with potential for exposure. While many of the epidemiologic studies to date suffer from methodologic problems, the data are suggestive of increased risks of fetal deaths associated with pesticides in general and maternal employment in the agricultural industry. There is a clear need for epidemiologic research that focuses on specific pesticide products or chemical families, with improved exposure assessment. The potential role of solvents in developmental toxicity associated with pesticide use by both males and females should also be considered.

Hexachlorobenzene accumulated by dams during pregnancy is transferred to suckling rats during early lactation. J Nutr 1997; 127:648-54.

Abstract
The distribution of ingested stable, lipophilic environmental pollutants in dams and their transfer to fetuses and sucklings were investigated in rats fed a diet containing a small amount (35.1 nmol/100 g diet) of hexachlorobenzene (HCB). In the first experiment, we examined the distribution of HCB in pregnant and nursing rats fed the HCB diet during pregnancy and lactation. Its transfer to their sucklings was also studied. On d 16 after parturition, HCB concentrations in the blood, and subcutaneous and perirenal fat of nursing rats fed the HCB diet during pregnancy and lactation were approximately 1/3.5, 1/15 and 1/2.8, respectively, those of pregnant rats fed the HCB diet only during pregnancy. On the other hand, the HCB concentrations in the blood, and subcutaneous and perirenal fat of sucklings were approximately 6, 29 and 15 times higher than those of their dams. Therefore, a large amount of HCB apparently was transferred from dams to suckling pups through the milk. In the second experiment, we fed dams the HCB diet only during pregnancy and determined the distribution of HCB in the pregnant rats and fetuses as well as in the nursing rats and suckling pups. The estimated amount of HCB transferred from a dam to her fetuses corresponded to about 0.39% of her total intake during pregnancy. The amount of HCB detected in nursing rats on d 16 after parturition was much smaller than that in the pregnant rats, suggesting that a large proportion of the HCB that accumulated during pregnancy disappeared from the organs and fat tissues during lactation. The HCB concentration in the stomach contents of suckling pups fed by the dams who had consumed HCB before parturition was highest on d 2 after birth and decreased gradually during the 16 d after birth. In the blood, liver and fat tissues of suckling rats, the HCB concentrations increased until 7 d after birth and then decreased gradually. We conclude that the HCB that accumulated in dams during pregnancy was transferred to their suckling pups through milk in the early days after birth.

Abstract
Trend monitoring of organochlorine contaminants, viz. PCBs, DDTs, HCHs and CHLs, was carried out by using formalin-preserved adipose tissue of Japanese males from 1928 through 1985 for understanding the long-term trends in their contamination levels. The highest residual concentrations were observed during the periods of maximum production (or import) and usage of these compounds in Japan. Time trends of the contaminants varied with the usage pattern and their physico-chemical properties. Effectiveness of government regulations on the production and use of organochlorines was seen faster in the case of DDTs and HCHs, which showed a prominent declining trend in their residues, whereas PCB levels exhibited a continuing increase and maintained a steady state even after two decades of a ban on their production, indicating that the exposure to PCBs is still prevailing. Generally, in terms of the spatial view, unlike aquatic fauna from the point-source environment (aquatic ecosystem) humans in the non-point-source environment (terrestrial habitat) revealed a slower rate of reduction in organochlorine residue burdens.

Abstract
Three patients with aplastic anaemia had a history of substantial previous exposure to organochlorine pesticides. The temporal association between chemical exposure and the onset of first symptoms of anaemia was strongly supportive. Organochlorines have the property of lipid affinity and accumulation in adipose tissue. Objective evidence of clinically important concentrations of tissue pesticide residues may be a useful confirmation of previous exposure. In the patients studied the presence of Lindane (gamma hexachlorocyclohexane) was shown using gas chromatography/mass spectrometry with selective ion monitoring of fragments obtained from one heavily exposed patient, with concentrations about five times greater than a matched control. The presence of clinically important tissue concentrations of pentachlorophenol was also confirmed in a second patient exposed to this agent. The long term safety of organochlorine pesticides remains doubtful as they were introduced before adequate toxicological screening tests had been developed. The central registration of possible haematological adverse reactions, however, forms an important epidemiological method in the study of environmental chemical hazards and should be complied with whenever possible.

Abstract
Between December 1982 and October 1983 samples of human body fat were taken during routine necropsies carried out on 187 persons aged over 5 years and four infants aged under 4 months. Comparison of the results of analysis with those from the previous studies in 1976-1977, and earlier, shows a continuing decline in residues of p,p'-dichlorodiphenyltrichloroethane (p,p'-DDT) and dieldrin (HEOD) and a reduction in the amounts of p,p'-dichlorodiphenyltichloroethane [p,p'-DDE, a metabolite of p,p'-DDT] and hexachlorobenzene. The concentrations of other compounds were similar to those observed in the previous studies. The results show that the amounts of organochlorine pesticides and polychlorobiphenyl compounds contained in human fat samples from residents in the UK compare favourably with data obtained in other countries.

Abstract
One hundred and five human adipose tissue samples were recovered during surgical operations or postmorten examinations of patients experiencing death due to traumatic injury. The sample donors were between the ages of 2 mo and 91 yr. Samples were analyzed by GLC-MS techniques for polychlorobiophenyl (PCB) and dichlorodiphenyl trichloroethane (DDT) compounds, chlordanes, hexachlorobenzene, and chlorinated phenols. Special attention was paid to the concentration of hepatchlor epoxide, a metabolite of heptachlor, commonly used as an insecticide in the Finnish plywood industry. The mean concentrations of PCB, DTTs, HCB, and chlordanes were 0.26, 0.33, 0.02, and 0.007 mg/kg fresh weight, respectively, while the mean concentration of heptachlor epoxide was 2.3 micrograms/kg. The geometric means were 0.20, 0.28, 0.018, 0.0055, and 0.002 mg/kg, respectively. The concentrations of PCB and DDT compounds in Finnish human adipose tissue has rapidly decreased during the last 10 yr. The average concentrations were higher in south Finland than those in north Finland, and the results clearly indicate the prominent influence of fish meals and the age of sample donors on the pollutant concentrations in adipose tissue. The results were further analyzed and discussed with respect to sex, smoking habits, and number of childbirths of the sample donors.

Abstract
Between May 1976 and August 1977 samples of human body fat were taken during routine necropsies in the United Kingdom on 236 subjects aged over 5 years and four infants aged under 4 months. Comparison with results from earlier studies showed a further decline in residues of pp'-dichlorodiphenyltrichloroethane (pp'-DDT) and dieldrin (HEOD) and increased amounts of hexachlorobenzene residues; concentrations of other compounds were similar to those observed in the studies carried out in 1963-4, 1965-7, and 1969-71. Comparison of the data with those from other countries, showed that the concentrations of organochlorine pesticide residues and polychlorobiphenyls in human fat samples from residents of the United Kingdom remain among the lowest in Europe and, indeed, the world.

Abstract
Adipose tissue of 50 human subjects (10 to 60 years old) were taken from autopsy cases and analysed by gas-liquid chromatography equipped with an electron capture detector (3H +) for determination of storage levels of BHC (benzene hexa chloride), DDT (dichlorodiphenyl trichloroethane) and its metabolites DDE and DDD in human body fat. The data is reported according to age (length of exposure), dietetic habits and area of residence of the subjects. The results show relatively moderate exposure to DDT and BHC. Levels of residues were slightly higher in non-vegetarian and rural residents than those of their counterpart vegetarian and urban inhabitants. The study suggests that DDT levels in human adipose show a decreasing trend as compared to earlier report of Dale et al. of highest body burden of pesticides being present in indians.

Abstract
The results of a preliminary search to determine the levels of organochlorine pesticide residues in the adipose tissue of the inhabitants of three Mexican cities of different socioeconomic characteristics are described herein. The concentrations and percent occurrence of nine compounds found are reported. In general, the samples analyzed had a large number of different organochlorine residues per sample. The results indicate that the inhabitants have been heavily exposed to 1,1,1-trichloro-2,2-bis (p-chloro-phenyl) ethane (DDT), and to a lesser degree, to 1,2,3,4,5,6,-hexachlorocyclohexane (BHC). The mean concentration of 1,1-dichloro-2,2-bis (p-chlorophenyl) ethylene (DDE) in one of the groups (18.36 ppm lipid basis) was one of the highest reported in the literature. It is also noteworthy that DDT was found in only 63, 89, and 55% of the samples from the three cities.

Abstract
Fifty specimens of placenta and accompanying fluid were collected at random from women of general population and analyzed for organo chlorine pesticides by gas liquid chromatograph using electron capture detector. BHC, Lindane, DDT, DDE, DDD and aldrin were detected in the placental tissue and accompanying fluid. Lindane, DDE and aldrin were more frequently detected. All the women were in their twenties but no correlation could be made between the compound and age, race or residence of the women. This is presumably the first attempt in India to detect the presence of pesticides in relation to their placental transfer, without occupational or accidental exposure.

Abstract
Using a novel in vitro technique, whereby microsomal enzymes were embedded in an agar layer to prolong their viability, 1,1-bis(p-chlorophenyl) ethylene(DDNU), a mammalian metabolite of 1,1-bis(p-chlorophenyl)-2,2,2-trichloroethane (DDT), was converted by microsomal mono-oxygenases of mouse liver into 1,1-bis(p-chlorophenyl)-1,2-ethanediol (DDNU-diol). The putative epoxide intermediate, 1,1-bis(p-chlorophenyl)ethylene oxide (DDNU-oxide), a new compound, was synthesized; it showed weak alkylating activity with 4-(4-nitrobenzyl)pyridine but was not mutagenic in Salmonella typhimurium strains TA100 and TA98. DDT and 13 of its metabolites or putative synthetic derivatives, including 1,1-bis(p-chlorophenyl)-2,2-dichloroethylene (DDE), 1 1,1-bis(p-chlorophenyl)-2-chloroethylene (DDMU), 1,1-bis(p-chlorophenyl)-2-chloroethane (DDMS)-DDNU, 2,2-bis(p-chlorophenyl)ethanol (DDOH), bis(p-chlorophenyl)acetic acid (DDA) and 1,1-bis(p-chlorophenyl)-2,2,2-trichloroethanol (Kethane), caused no mutagenic effects in S. typhimurium strains TA100 or TA98, either in the presence or absence of a mouse-liver microsomal fraction. 1,1-Bis(p-chlorophenyl)-2,2,2-trichloroethyl acetate (Kelthane acetate) was a direct-acting mutagen in strain TA100, whereas 1,1-bis(p-chlorophenyl)-2,2-dichloroethane (DDD) was mutagenic in TA98, only in the presence of a mouse-liver microsomal system. The results are discussed in relation to possible pathways whereby DDT is activated to mutagenic and/or carcinogenic metabolites.

Abstract
Fifty samples of human breast milk were analysed by gas chromatography and thin layer chromatography for DDT (dichlordiphenyltrichloraethan), hexachlorobenzol, benezene-hexachlorides, dieldrin, aldrin and heptachlorepoxide. The three first substances were found in all samples in amounts varying from quite small up to eleven times the WHO recommended maximum for cow milk. The other substances were found in fewer milk samples, however, in some of these samples they were found in relatively high amounts. In Norway, only DDT has been investigated earlier (4), and compared to that study, there has been no significant change in the mean concentration of DDT in human breast milk during the last five years. The insecticide content was highest in colostrum and decreased with increasing duration of lactation. Considerable fluctuations in the content of insecticides were recorded in repeated milk samples collected from the same woman a few days apart. The percentage of samples with insecticide content higher than that permitted for cow's milk was greater in May/June (79%) than in early April (54%). The significance of these findings is discussed.
