"Water, bottom sediment and oligochaetes were analysed for heavy metals as part of an environmental assessment of the contamination of Collingwood Harbour, Ontario by shipbuilding and industrial activity. Compared to western Lake Ontario, Collingwood Harbour showed higher concentrations of dissolved, available Cd, Cr, Pb and Cu. Cadmium concentrations increase from the inner harbour to the outer harbour and this distribution appears to be related to release from the sediments. The concentration of this metal in the outer harbour exceeds the average value measured in a related study for the southeastern part of Hamilton Harbour. In general, the data show that Collingwood Harbour does exhibit contamination by Cd, Cu and Pb"--Exec. summary.
