Spatial alternation deficits following developmental exposure to Aroclor 1254 and/or methylmercury in rats.
Polychlorinated biphenyls (PCBs) and methylmercury (MeHg) are ubiquitous environmental contaminants that alter cognitive function in both humans and animals. Because PCBs and MeHg often occur together in the environment, it is important to understand whether these two contaminants have the potential to interact, causing additive or greater than additive effects. The current study examined the c...
متن کاملGenetic susceptibility to methylmercury developmental neurotoxicity matters
Epidemiological studies have demonstrated the developmental neurotoxicity associated with prenatal methylmercury exposure (Grandjean and Landrigan, 2006); However, susceptibility to methylmercury toxicity may be increased by genetic factors. This observation raises the question of possible dependence of developmental neurotoxicity on genetic predisposition. A few years ago, a National Research ...
متن کاملMethylmercury: significance of intrauterine and postnatal exposures.
Outbreaks of methylmercury poisoning in Japan and Iraq have demonstrated the sensitivity of the fetus to neurotoxic effects. Based on toxicokinetics and considerations of practicability, the optimal biomarker of methylmercury exposure is the hair concentration, but whole-blood measurements of mercury are also useful. Dose-response relations are still incompletely known, especially concentrating...
متن کاملMethylmercury exposure and developmental neurotoxicity
We are concerned that certain aspects of the systematic review on methylmercury (MeHg) exposure from seafood consumption and the risk of developmental neurotoxicity published in the Bulletin of World Health Organization could be misinterpreted.1 Specifically, the review does not address the issue of whether naturally-occurring, background levels of prenatal exposure to MeHg from maternal fish c...
متن کاملApartment residents' and day care workers' exposures to tetrachloroethylene and deficits in visual contrast sensitivity.
Tetrachloroethylene (also called perchloroethylene, or perc), a volatile organic compound, has been the predominant solvent used by the dry-cleaning industry for many years. The U.S. Environmental Protection Agency (EPA) classified perc as a hazardous air pollutant because of its potential adverse impact on human health. Several occupational studies have indicated that chronic, airborne perc ex...
