Description:

Objective:

The FRIENDS Children's Environmental Health Center is a university/community partnership, which was established to investigate the health effects of combined exposure to polychlorinated biphenyls (PCBs) and methylmercury (MeHg) in Hmong and Laotian refugees consuming contaminated fish from the Fox River in northeastern Wisconsin. PCBs and MeHg are neurotoxic compounds that tend to occur together in the environment, especially in fish and seafood. Recent research suggests that the two compounds may have additive or synergistic effects on nervous system function. The goals of the FRIENDS Center are to study the impact of PCB and MeHg exposure on women's reproductive health and child development-focusing on neuropsychological development, to develop effective educational strategies to reduce exposure to these contaminants in reproductive age women and children, and to conduct laboratory studies aimed at understanding the mechanisms through which these contaminants induce neurological deficits in children. Partners in the research include the Hmong Association of Green Bay and the Fort Howard/Jefferson Neighborhood Family Resource Center of Green Bay, as well as researchers from the University of Illinois at Urbana-Champaign, Texas A & M University, Michigan State University, the University of Illinois at Chicago, SUNY Buffalo and the New York State Department of Health.

This particular project is being conducted at the University of Illinois at Urbana-Champaign. The primary objectives are to characterize the cognitive, motor and sensory effects of perinatal exposure to PCBs alone, MeHg alone or PCBs and MeHg in combination in the laboratory rat, to investigate the role of changes in specific neurotransmitter systems in mediating specific behavioral effects, to investigate the role of altered thyroid hormones in mediating specific behavioral effects and to use the results from these animal experiments to guide the selection of behavioral tests for use in children exposed to PCBs and MeHg through maternal consumption of contaminated fish.
