The bioaccumulation of a broad range of pharmaceuticals and personal care product chemicals (PPCPs) was studied in Cootes Paradise Marsh (CPM), an urban wetland that receives tertiary treated municipal waste waters as well as urban storm runoff. PPCPs were measured in caged and wild goldfish, as well as wild carp, and compared to observed bioaccumulation factors (BAFs) using concentrations in surface waters and fish blood plasma, with modeled BAFs. Thirty-two PPCPs were detected in water from the central CPM site (CPM3) while 64 PPCPs were found at higher concentrations at a site immediately downstream of the effluent outflow (CPM1). Following a 3-week deployment, 15 PPCPs were detected in the plasma of caged goldfish at CPM1, and 14 at CPM3, compared to only 3 in goldfish caged at a reference site. This study identified a broader range of PPCPs in fish and surface waters than previously reported. However, modeled BAFs did not show good agreement with observed whole body or plasma BAFs, demonstrating that more work is needed to better explain bioaccumulation of PPCPs.
Supplemental Information
Funding for this study was provided in part by the Government of Canada’s Great Lakes Action Plan (GLAP) and in support to Hamilton Harbour 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, municipalities and environmental non-government organizations to address these impacts. Today over 900 restoration projects have been successfully completed by Environment and Climate Change Canada and partners including Wastewater Treatment Plant upgrades, fish and wildlife habitat restoration, and water quality improvements.
