摘要：The freshwater quality criteria of acetonitrile were studied on the basis of the features of the aquatic biota in China, and with reference to US EPA's guidelines. Acute tests were performed on 13 different species to determine 48h-EC50/96h-EC50 (or 96h-LC50) values for acetonitrile. 21d survival-reproduction tests with Daphnia magna and growth inhibition tests with Lemna minor were also conducted to estimate lower chronic limit and upper chronic limit values. In the acute tests, Radix plicatula was the most sensitive species to acetonitrile followed by Chironomus sp., Cyprinus carpio and D. magna in turn. The final acute value of acetonitrile was 2290 mg/l. In the chronic tests, reproduction of daphnids was significantly reduced by acetonitrile at 320 mg/l. Acute-to-chronic ratios ranged from 2 to 15.8. A final chronic value of 413.9 mg/l was obtained and a final plant value was 1342 mg/l. A criterion maximum concentration (1145 mg/l) and a criterion continuous concentration (413.9 mg/l) were derived.
