摘要: The bioaccumulation of organic contaminants in the Lake Erie food web is reviewed context numerous changes experienced by system. In late 1960s, internal lake processes, related to eutrophic status lake, minimized contaminant despite high loadings. From 1970s 1980s concentrations decreased at different rates many species trophic levels, coincident with loadings lake. Since early biota have not changed consistently. Several factors been proposed account for these patterns, including reduced nutrient and productivity, invasion several exotic such as zebra mussels. These altered structure distribution Emerging continuing issues, climate change, invasions additional species, new chemical concern, algal toxins will l...
