Toxicological significance of mercury in freshwater fish
A National Pilot Study of Mercury Contamination of Aquatic Ecosystems along Multiple Gradients
Mercury (Hg) contamination of aquatic ecosystems is a global problem. However, databases for Hg in environmental samples at regional-to-national scales are few, especially for multi-media samplingExpand
Effects of dietary methylmercury on reproduction of fathead minnows.
We examined effects of dietary methylmercury (MeHg) on reproduction of fathead minnows (Pimephales promelas). Juvenile fish were fed one of four diets until sexual maturity (phase 1): a control dietExpand
Toxicity of dietary methylmercury to fish: derivation of ecologically meaningful threshold concentrations.
Threshold concentrations associated with adverse effects of dietary exposure to methylmercury (MeHg) were derived from published results of laboratory studies on a variety of fish species. AdverseExpand
The Weibull Distribution: A New Method of Summarizing Survivorship Data
Survivorship data can be effectively summarized using the shape and scale parameters of the Weibull frequency distribution. The shape parameter controls the rate of change of the age- specificExpand
Metal bioavailability and toxicity to fish in low-alkalinity lakes: A critical review.
Fish in low-alkalinity lakes having pH of 6.0-6.5 or less often have higher body or tissue burdens of mercury, cadmium, and lead than do fish in nearby lakes with higher pH. The greaterExpand
Mercury in soils, lakes, and fish in Voyageurs National Park (Minnesota): importance of atmospheric deposition and ecosystem factors.
Concentrations of methylmercury in game fish from many interior lakes in Voyageurs National Park (MN, U.S.A.) substantially exceed criteria for the protection of human health. We assessed theExpand
Mercury accumulation in yellow perch in wisconsin seepage lakes: Relation to lake characteristics
We studied relations between lacustrine characteristics and the total mercury (Hg) content of calendar age-2 yellow perch (Perca flavescens) in 10 seepage lakes in north-central Wisconsin. MeanExpand
