There was extensive mercury pollution caused by Dryden Chemicals Company's waste water effluent in the Wabigoon-English River system. [87] [88] Because local fish were no longer safe to eat, the Ontario provincial government closed the commercial fisheries run by the First Nation people and ordered them to stop eating local fish. The first book of its kind, Environmental Electrochemistry considers the role that electrochemical science and engineering can play in environmental remediation, pollution targeting, and pollutant recycling. Electrochemical-based sensors and abatement technologies for the detection, quantification, and treatment of environmental pollutants are.

Ontario Minamata disease is a neurological syndrome caused by severe mercury occurred in the Canadian province of Ontario, inand severely affected two First Nation communities in Northwestern Ontario following consumption of local fish contaminated with mercury, and one First Nation in Southern Ontario due to illegal disposal of industrial chemical waste.

Dryden Chemical first stores mercury waste onsite for later safe disposal, and eventually changes its processes to eliminate its use of mercury altogether. Report on mercury poisoning never shared, Grassy Narrows leaders say after a paper mill dumped the mercury into the Wabigoon-English River.

Several organisms used for biomonitoring in the mercury‐contaminated Wabigoon–English River System, Ontario, Canada (sport fish, forage fish, crayfish and others) were examined for their utility as bioindicators.

Causes for spatial and temporal variability in mercury concentrations in biota are reviewed. The significance of intertrophic and intratrophic biotic relationships is evaluated on.
