Halogenated Phenolic Compounds in the plasma of Toronto and Region AOC Brown bullhead

This dataset contains the concentrations of halogenated phenolic compounds in plasma for the fish species Brown bullhead (Ameiurus nebulosus), from 3 site locations (Frenchman's Bay, Tommy Thompson, and Toronto Island) within the Toronto and Region Area of Concern.

Halogenated Phenolic Compounds have emerged as an important class of environmental contaminants in aquatic vertebrates, wildlife, and humans. They represent 4 of the 7 classes of substances listed as chemicals of mutual concern in the Great Lakes.

Supplemental Information

Funding for this study was provided in part by the Government of Canada’s Great Lakes Action Plan (GLAP) and in support toToronto and Region Area of Concern.

In 1987 under the revised Great Lakes Water Quality Agreement, 43 areas of concern (AOC), 12 of which are located in Canada,were identified as having severely impaired beneficial uses and water quality. As funded by the Great Lakes Action Plan,a Remedial Action Plan was formed for each area of concern bringing together experts from government, industry, municipalitiesand environmental non-government organizations to address these impacts. Today over 900 restoration projects have beensuccessfully completed by Environment and Climate Change Canada and partners including Wastewater Treatment Plant upgrades,fish and wildlife habitat restoration, and water quality improvements
