"This chapter gives an overview of the Niagara River/Lake Ontario pollution situation even though the discussion is focussed on only five contaminants - the chlorobenzenes. The paper shows that volatilization is an important process that requires more research because it has the potential to spread contaminants from the river and lake over wide areas and over long distances. In the lake itself, the sediments are demonstrated to be the most important chemical sink and could act as a future source after loadings are reduced. Consumption of contaminated fish from Lake Ontario is shown to be much more important than drinking water consumption for the CBs and other chemicals with similar properties. Historical contamination trends of the lake from sediment cores indicate improvement over the long term, but some new information (in the last 1 to 3 years) may point to worsening contamination. More studies are required to see if this recent trend is correct. The cleanup of dumpsites and direct discharges appears to be the only long-term solution to the problem"--Management perspective.
