Abstract The concentration distribution of hexachlorobutadiene (HCBD), pentachloro-benzene (QCB), hexachlorobenzene (HCB) and octachlorostyrene (OCS) in water samples from transects across the upper and lower St. Clair River and the upper Detroit River were determined on four occasions in 1985. The data show a plume of these contaminants from the Sarnia industrial area. The fluxes and concentration profiles of the contaminants at Port Lambton have been modelled success fully using a simple transverse mixing model. A study on the chemical partitioning between the “dissolved” and “suspended sediment” phases shows that an important contaminant fraction is carried in the river by the suspended solids, particularly for lipophilie compounds such as HCB and OCS,

Measured Response

The laboratory estimation of the toxic effects of organic pollutants relies on successive investigations of increasing sensitivity. Acute toxicity tests are useful in providing an index of relative toxicity between compounds but are of limited value for making ecological predictions. Many factors can influence the assessment of acute toxicity, with chemical stability of the test solutions and the species of test organisms employed being perhaps the most important of these. Many sub-lethal tests are also of limited value because the importance of the measured response for the well-being of the animal community as a whole is not established. The basic requirements of sub-lethal techniques are discussed, especially in relation to compounds which may exert their toxic action through accumulation in the tissues in the long term. The possibility of relating the toxicity of a compound to its chemical structure is considered.
