Description of key information

Two studies are available:
1) An acute aquatic study (Holmes, 1991) is available which is key study. This study showed that 48-hour EC50 of the test substance is 0.139 mg/L.
2) An acute aquatic study (Carter, 1987) is available which is supporting study. This study showed that 48-hour EC50 of the test substance is 0.27 mg/L.

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
0.139 mg/L

Additional information

Two studies are available:

1) A primary acute aquatic study was conducted according to EPA OPP 72-2 using Daphnia magna (Holmes, 1991). Key study.

This study showed that the test substance is toxic to aquatic life.

2) The key value was supported by another study performed with Daphnia magna (Carter, 1967). Supporting study.
