Recent studies have shown that significant amounts of arsenic are transported from one lake to another, and that levels of mercury up to 2ug/g have accumulated in some fish species. This report presents the results of the first year of an investigation into the pathways of arsenic and mercury in the lake ecosystem"--Exec. summary. |
