Description of key information

In the reliable key study (BASF, 1991), the test substance's toxicity to Daphnia was determined to be EC50 = 19.9 mg/l

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
19.9 mg/L

Additional information

Two reliable studies are available.

The more recent and better documented study was assigned as key study (BASF, 1991).

However, the other study (BASF, 1988) supports the key study with an almost identical EC50 (19.0 mg/l).
