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 sampling
Effects of dietary methylmercury on reproduction of fathead minnows.
TLDR
MeHg decreased reproduction of adult fathead minnows at dietary concentrations encountered by predatory fishes in aquatic systems with MeHg-contaminated food webs, implying that exposed fish populations could be adversely affected by this widespread contaminant.
Toxicity of dietary methylmercury to fish: Derivation of ecologically meaningful threshold concentrations
TLDR
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 and indicate that while differences in species sensitivity to MeHg exposure appear considerable, chronic dietary Exposure to low concentrations of MeHG may have significant adverse effects on wild fish populations but remain little studied compared to concentrations in mammals or birds.
The Weibull Distribution: A New Method of Summarizing Survivorship Data
TLDR
The shape parameter controls the rate of change of the age- specific mortality rate and, therefore, the general form of the survivorship curve.
Mercury in soils, lakes, and fish in Voyageurs National Park (Minnesota): importance of atmospheric deposition and ecosystem factors.
TLDR
It is concluded that nearly all of the mercury in fish in this seemingly pristine Voyageurs National Park, MN, U.S.A., is from anthropogenic sources.
