Additional information

Two chronic tests are available, one with freshwater species and one with a marine species. Both studies are conducted according to accepted guidelines. The 21-d NOEC in Daphnia magna is 51 mg/l (Wildlife International Ltd., 1999g), the 28-d NOEC in mysid shrimp (Americamysis bahia) is 26 mg/l (Wildlife International Ltd., 1999h). These values will be used in the assessment.
