| 520 | 3 |a"Three surveys of the Ottawa River were carried out in May, August and October 1980, in the National Capital Region, to determine ambient levels of hexachlorobenzene, organochlorine pesticides and total PCBs (polychlorinated biphenyls) in water. Quantifiable residues were most frequently found during the May survey. Methoxychlor, heptachlor epoxide, dieldrin and total PCBs showed indications of having temporal variation. Contaminants were found more frequently at stations affected by point source discharges and at sites located on tributaries of the Ottawa River. Ontario Ministry of the Environment aquatic life objectives for dieldrin and total PCBs were exceeded at least 10% of the time, suggesting that further investigation is warranted"--Abstract, p. v. |
