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.
