Short-term toxicity tests on the alga, Selenastrum capricornutum were performed using dimethylamine, diethylamine, di-n-butylamine, diisopropylamine, tert-butylamine, aniline, cyclohexylamine and morpholine, and the mean concentrations inhibiting 50 per cent of the algal population at 96 hours (96-hour EC50) were determined. Acute toxicity tests of the amines using Daphnia magna determined the 24-hour immobilization concentrations for 50 per cent of the population, and 96-hour LC50 values with Salmo gairdneri were determined both in soft water and in hard water. Respirometric assays were performed using Sapromat equipment and bacteria from river mud, treatment plant sludge, and adapted sludge bacteria. Degradation behaviour of the amines could be predicted from their chemical and physical properties. On the basis of a hazard scale of 1-9 (9 being a high hazard), the 8 amines were all regarded in the region 4-6 in terms of bioaccumulation.
