Over 25 % of pesticides and other toxic organic pollutants are chiral, as are 19 of the 209 polychlorinated biphenyl (PCB) congeners; that is, they exist as two mirror image species called enantiomers (PCB enantiomers are called atropisomers). The enantiomers of a chiral compound have identical physical and abiotic chemical properties, but usually differ in biological properties such as microbial degradation, uptake and transport across membranes, metabolism rate, and toxicity. Chirality in the environment has become recognized as an important phenomenon since the mid-1980s, and related research has centered on the need to understand the environmental fate and effects of pesticides and PCBS. This article provides a brief back- ground on chiral chemistry in general and the importance of chirality in the drug industry, followed by a summary of examples of the enantioselectivity ofpesticide and PCB occurrencesand degradation in the environmentasgleaned from the scientific literature.

*  The Effects of Polychlorinated Biphenyl on Circulating Leptin and Thyroid Hormone Status in Sprague-Dawley Rats, Rattus...
Polychlorinated biphenyls (PCB) are persistent environmental chemicals that are known thyroid hormone disrupters. Frequently the disruption of one endocrine axis and the timing of the disruption have an impact on other interdependent hormonal responses. Although the mechanisms for the interdependency of thyroid hormones and leptin have not been fully characterized, both are linked to development and regulation of metabolism. Furthermore, PCB accumulation in depot fat could potentially alter leptin production. In the present study 15-and 30-day-old Sprague-Dawley rats were exposed gestationally and lactationally to 1.25 ppm of Aroclor 1254®, a mixture of 52 PCB congeners, via maternal diet, to determine the effect on leptin and thyroid hormones. Additionally, young adult female rats were fed 1.25 PCB for 21 days and the same hormones were assessed. Serum leptin concentrations were determined by a sensitive murine leptin ELISA (DSL, Inc., Webster, TX). Serum thyroid hormone ...

*  Effects of Maternal Exposure to Polychlorinated Biphenyls on Notch Signaling in the Fetal Rat Brain| Research Project...
PCBs are industrial chemicals that have neurotoxic effects, and studies indicate that they interfere with normal functions of the endocrine system. Although the manufacturing of PCBs was banned in the 1970s, they remain a major contaminant of the environment and of human tissues. Epidemiological studies show that exposure to PCBs during intrauterine development is highly associated with measurable neurological deficits in the offspring. In addition, deficits associated with PCBs are inversely associated with maternal thyroid hormone (TH) levels. This suggests that PCBs interfere with TH action in the fetal brain. Using in situ hybridization to measure HES-1 and HES-5 mRNA (direct markers of Notch activity), our laboratory has found that both maternal thyroid status and maternal exposure to PCBs influences Notch signaling in the fetal rat brain. We found that Aroclor 1254 produces a dose-dependent increase in HES-1 expression in the ventricular zone. Recent evidence suggests that Notch signaling ...

The objectives of this study are (1) to evaluate the current status of thyroid function in developing Herring gulls (Larus argentatus) from Great Lakes sites with different chemical pollutant exposures and (2) to determine, using laboratory studies on developing chickens (Gallus domesticus), if the disruption of avian thyroid function by polychlorinated biphenyls (PCBs; key contaminants at many Great Lakes sites) is similar mechanistically to that in laboratory mammals. Herring gulls, a fish-eating, top-predator, have been used as a sentinel species to monitor the concentrations and biological effects of environmental contaminants in the Great Lakes for more than 25 years. Past research has focused on mortality, developmental abnormalities and reproductive effects of chemical pollutants in the lakes. Studies of thyroid histology and developmental effects suggest that thyroid function is disrupted in these gulls. This study examines the thyroid status of developing gulls in ...

Background: Polychlorinated biphenyls (PCBs) and their hydroxylated metabolites (HO-PCBs) interfere with thyroid hormone action both in vitro and in vivo. However, epidemiologic studies on the link between PCB exposure and thyroid function have yielded discordant results, while very few data are available for HO-PCBs. Objectives: Our study aimed at investigating the relationship between clinically available markers of thyroid metabolism and serum levels of both PCBs and HO-PCBs. Subjects and Methods: In a group of 180 subjects, thyroid-stimulating hormone (TSH) and free thyroxin (fT4), 29 PCBs (expressed both in lipid weight and in wet weight) and 18 HO-PCBs were measured in serum. Results: In regression models, adjusted for gender, age, current smoking behavior, BMI and total lipid levels, serum levels of 3HO-PCB118 and 3HO-PCB180, and PCB95lw, PCB99lw and PCB149lw were independent, significant predictors of fT4.

We used multiprobe fluorescence in situ hybridization (FISH) for chromosomes X, Y, and 18 to determine XX, YY, XY, and total sex-chromosome disomy in sperm nuclei. Serum was analyzed for concentrations of 57 PCB congeners and p,p'-DDE. Poisson regression models were used to calculate incidence rate ratios (IRRs) for disomy by exposure quartiles, controlling for demographic characteristics and semen parameters.,The median percent disomy was 0.3 for XX and YY, 0.9 for XY, and 1.6 for total sex-chromosome disomy. We observed a significant trend of increasing IRRs for increasing quartiles of p,p'-DDE in XX, XY, and total ...

Dioxin-like chemicals and brominated flame retardants are ubiquitous in the environment, despite the introduction of international prohibitions and restrictions. These chemicals do not remain in the vicinity of their source, instead they can be transported over long distances, in fact even to pristine areas in the northern latitudes. However, there have been rather few time series experiments monitoring the trends in the levels of chlorinated and brominated forms of these chemicals in the environment. In this study, the concentrations of polychlorinated dibenzo-p-dioxins and -furans (PCDDs/Fs), polychlorinated biphenyls (PCBs) and polybrominated diethyl ethers (PBDEs) were measured in the liver and muscle of bank voles (Myodes glareolus) caught in a remote area in Finnish Lapland during 1986-2007. Five time points were selected: years 1986, 1992, 1998, 2003 and 2007. The levels of PCDDs/Fs and PCBs declined from 1986 until 2003 in both females and males, but tended to ...

The objective of this analysis was to evaluate mortality among a cohort of 24,865 capacitor-manufacturing workers exposed to polychlorinated biphenyls (PCBs) at plants in Indiana, Massachusetts, and New York and followed for mortality through 2008. Cumulative PCB exposure was estimated using plant-specific job-exposure matrices. External comparisons to US and state-specific populations used standardized mortality ratios, adjusted for gender, race, age and calendar year. Among long-term workers employed 3 months or longer, within-cohort comparisons used standardized rate ratios and multivariable Poisson regression modeling. Through 2008, more than one million person-years at risk and 8749 deaths were accrued. Among long-term employees, all-cause and all-cancer mortality were not elevated; of the a priori outcomes assessed only melanoma mortality was elevated. Mortality was elevated for some outcomes of a priori interest among subgroups of long-term workers: all cancer, ...

Epidemiological studies suggest that exposure to persistent organic pollutants such as organochlorines might induce cardiovascular disorders and diabetes. Some of these organochlorines, such as dioxins and some dioxin-like PCBs, have been characterised as anti-estrogenic due to their inhibition of estrogenic-induced responses. In the present pilot study, 40 female rats were subjected to either exposure to the dioxin-like 3,3',4,4',5-pentachlorobiphenyl (PCB 126) or vehicle, as well as ovariectomy (OVX) or sham operation in a 2 x 2 factorial design over 12 weeks to explore potential interactions between estrogen status and PCB 126 exposure on cardiovascular risk factors. PCB 126 increased heart weight and serum cholesterol levels in both groups. PCB 126 increased blood pressure in the sham-operated animals only. In conclusion, PCB 126 exposure in female rats resulted in effects on cardiovascular risk factors, such as serum cholesterol, blood pressure, and heart weight. Of these effects of PCB ...
