Conclusion and Prospects
Although all the questions regarding the source and fate of mercury (Hg) in natural and modified aquatic ecosystems of northern Québec have yet to be answered, the findings of over 10 years of studies, as well as of over 20 years of monitoring, in the area have enabled a comprehensive assessment of the biogeochemical processes involved. They have also permitted the definition of the importance and duration of the phenomenon of increased fish Hg levels in reservoirs. Except for a limited number of species, the risk it represents to fish consuming wildlife remains to be evaluated.
