| 520 | |a"Levels of hazardous contaminants coming into the lake from the upper Lakes and the Niagara River remain high, but some toxic metals, PCB and Mirex, have fallen considerably since the 1970s. Atmospheric deposition, upstream lakes, and municipal and industrial discharges continue to be important sources of contaminants within the lake watershed. Other important geoscience or sediment-related issues are seismic risks to an increasingly urbanized shore-zone, shore erosion, and the effects of habitat change brought about by zebra mussel colonization of the benthic environment in Lake Ontario"--Abstract. |
