Three species of fish, caught at various distances from a kraft pulp ai:d paper mill effluent discharge in Nipigon Bay, were analyzed for organic contaminants. Fishes from all sites contained residues of polychlorinated biphenyls and DDE. Most samples were also contaminated with hexachlorobenzene and several samples contained phthalic acid esters. From sampling sites close to the mill discharge, dehydroabietic acid was observed in one extract of each of the three fish species investigated. Two isomers oftetrachlorobenzene and one trichlorobenzene isomer were identified in a longnose sucker (Cutostomils cotostomiis) extract from the vicinity of the mill outfall. KAISER. K. L. E. 1977.

Nous avons dose les substances organiques contaminantes dans trois especes de poissons capturees a diverses distances de I'effluent d'un moulin de phte et de papier kraft dans la baie Nipigon. Les poissons provenant de tous les sites contiennent des residus de biphenyls polychlores et de DDE. La plupart des echantillons sont igalement contamines par I'hexachlorobenzene, et plusieurs ichantillons condennent des esters d'acide phthalique. Aux sites d'echantillonnage a proximite de I'emissaire du moulin, nous avons observe de I'acide deshydroabietique dans un extrait de chacune des trois especes de poissons etudiees. Nous avons identifie deux isomtres de tetrachlorobenzene et un isomere de trichlorobenzene dans un extrait de meunier rouge (Cntostomits carosromits) captur6 dans le voisinage de I'emissaire du moulin.
