Description of key information

The 21-d NOEC is 51 mg/l in Daphnia magna. For marine invertebrates the 28-d NOEC is 26 mg/l found in Americamysis bahia.

Key value for chemical safety assessment

EC10, LC10 or NOEC for freshwater invertebrates:
51 mg/L
EC10, LC10 or NOEC for marine water invertebrates:
26 mg/L

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.
