Rainbow trout (Salmo gairdneri) were examined for the presence of dehydroabietie acid after exposure to kraft mill effluent. Levels of 2 to 10 [mu]g/g dehydroabietie acid on a whole fish wet weight basis were found in fish exposed to 3 to 18% effluent for 48 to 144 hours. Less than 1 [mu]g/g dehydroabietie acid was found in control fish which had been acclimated in Nipigon Bay water for two weeks and no residue was detected in an unexposed fish. It is concluded that fish exposed to kraft mill effluent accumulate dehydroabietie acid to a level which is likely to result in sublethal toxic effects.
