Adverse Effects of Methylmercury: Environmental Health Research Implications
BACKGROUND The scientific discoveries of health risks resulting from methylmercury exposure began in 1865 describing ataxia, dysarthria, constriction of visual fields, impaired hearing, and sensory disturbance as symptoms of fatal methylmercury poisoning. OBJECTIVE Our aim was to examine how knowledge and consensus on methylmercury toxicity have developed in order to identify problems of wide...
متن کاملInteraction between selenium and methylmercury.
The available data on the influence of selenium on the toxicity of methylmercury and of methylmercury on selenium as a nutrient and toxic agent are reviewed. Selenium as selenite has a relative protective effect on acute and subacute toxicity of methylmercury in the rat and the quail. The protective mechanism is far from clear. Of special interest is the fact that selenium-treated animals may r...
متن کاملNIEHS Extramural Global Environmental Health Portfolio: Opportunities for Collaboration
BACKGROUND Global environmental health has emerged as a critical topic for environmental health researchers and practitioners. Estimates of the environmental contribution of total worldwide disease burden range from 25 to 33%. OBJECTIVE We reviewed grants funded by the National Institute of Environmental Health Sciences (NIEHS) during 2005-2007 to evaluate the costs and scientific composition...
متن کاملHow should federal policy reflect recent research in the area of intrauterine exposure to environmental hazards?
Present policy neither evaluates nor adequately protects the fetus from the effects of intrauterine exposure to environmental hazards. Some examples are intrauterine lead and methylmercury exposure and intrauterine PCB exposures. A sound policy based on a few basic principles can be developed to protect the fetus from harm from intrauterine exposures.
متن کاملMethylmercury in the environment: a review of current understanding.
The danger of methylmercury poisoning appears to be slight when the environment is not directly contaminated with methylmercury. Sediments rapidly bind mercury and decrease its availability to aquatic organisms. Sediments further have a greater propensity to demethylate than to methylate mercury. In noncontaminated aquatic ecosystems, the concentrations of methylmercury and inorganic mercury ar...
