| Popis: | Water, bottom sediment and two species of fish collected upstream of the mouths of the Moose, Albany, Attawapiskat, Winisk and Severn Rivers were analyzed for heavy metals and a wide range of organic contaminants. Iron and aluminum were present in raw water samples with mean concentrations ranging from 260 to 860 ug/L and 60 to 470 ug/L respectively. Polycnlorinated biphenyls (PCBs), α-BHC, γ-BHC, cis-chlordane, trans-chloroane, p,p’-DDE, dieldrin and HCB were also found in water at levels comparable to an industrialized region of Ontario. Organochlorine pesticides, cnlorobenzenes, polyaromatic hydrocarbons and phthalates were not detected in bottom sediments, however, trace amounts of PCBs were found in Moose and Severn River sediments. Trace concentrations of a few organochlorine contaminants were detected in both fish species. The solubi1ization, absorption and bioaccumulation of many of the contaminants were thought to have been affected by the presence of naturally occurring organic acids. |
