A meeting on the health effects of arsenic (As), its modes of action, and areas in need of future research was held in Hunt Valley, Maryland, on 22-24 September 1997. Exposure to As in drinking water has been associated with the development of skin and internal cancers and noncarcinogenic effects such as diabetes, peripheral neuropathy, and cardiovascular(More)
Bouncing Through Fractions, Percentages and Probability, which is designed for a sixth grade class of twenty to twenty-five students, is a mathematical program that allows kids to learn fractions, percentages, and probability while studying NCAA female and male basketball players' statistics. It is designed to bridge the gap between events in the NCAA March(More)
Acid precipitation may increase human exposure to several potentially toxic metals by increasing metal concentrations in major pathways to man, particularly food and water, and in some instances by enhancing the conversion of metal species to more toxic forms. Human exposures to methylmercury are almost entirely by way of consumption of fish and seafood. In(More)
The history of advances in the understanding of the toxic effects of lead over the past 20 years is an outstanding example of how knowledge learned from research can impact public health. Measures that have had the greatest impact on reducing exposure to lead are reduction of lead from gasoline, elimination of lead solder from canned food, removal of lead(More)
Although the toxicity of lead was recognized centuries ago, concern was restricted to overt symptoms: colic, encephalopathy, anemia, or renal disease. Two major reasons for lack of progress in restricting toxicity were that interest was limited to occupational exposures and there was lack of awareness of specific biochemical or metabolic effects.(More)
The role of chelating agents for the prevention , intervention, and treatment of exposures to toxic metals was the topic of a conference held at the National Institute of Environmental Health Sciences, 22-23 September 1994. The objective of the conference was to review experimental and clinical studies concerned with the effectiveness and potential toxicity(More)
The purpose of this study is to determine if there is an anatomical correlate, namely adrenal hypertrophy, among people who have committed suicide. The adrenal weights and other relevant information were collected prospectively from 118 consecutive coroner's cases of sudden death in the province of Ontario. No statistically significant difference was found(More)
