Description of key information

The lowest 48-h EC50 is 100 mg/l in Daphnia magna. For marine invertebrates the 96-h LC50 is 14 mg/l in Americamysis bahia.

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
100 mg/L
EC50/LC50 for marine water invertebrates:
14 mg/L

Additional information

There are several guideline studies available for freshwater invertebrates. The most critical study for is therefore chosen as the key study. For freshwater invertebrates the lowest observed effect concentration is a 48-h EC50 value of 100 mg/l in Daphnia magna (Springborn Laboratories, Inc., 1994b). For marine invertebrates only one study was available. The study was conducted according to accepted guidelines and gave a 96 -h LC50 of 14 mg/l in Americamysis bahia (Springborn Laboratories Inc,., 1994c). Both values will be used in the assessment.
