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 …

Mercury contamination of remote lakes has been attributed to increasing deposition of
atmospheric mercury, yet historic deposition rates and inputs from terrestrial sources are …

The trophic structure of pelagic communities in glaciated regions is highly variable due to
restricted dispersal of glacial relict taxa and recent species introduction. Much of the …

Atmospheric mercury is the dominant Hg source to fish in northern Minnesota and
elsewhere. However, atmospherically derived Hg must be methylated prior to accumulating …

Historic increases in atmospheric mercury deposition caused by anthropogenic emissions
have been well documented from sediment cores from lakes and peatlands in North …

Complex and ever changing in its forms and functions, the element mercury follows a
convoluted course through the environment and up the food chain. The process is …

The history of mercury (Hg) inputs to 55 Minnesota (USA) lakes was reconstructed from
210Pb (lead‐210)‐dated sediment cores to determine if erosion of soils from agriculture and …

The trend of mercury concentrations in standardized length northern pike (NP55) and
walleye (WE40) was evaluated for a 25-year period, 1982− 2006, based on a data set of …

More than three centuries ago, European colonists settled the deciduous forest along the
eastern coast of the North American continent. These colonists soon became familiar with …

Mercury contamination of fish is a global problem. Consumption of contaminated fish is the
primary route of methylmercury exposure in humans and is detrimental to health. Newly …
