Description of key information

Short-term toxicity to aquatic invertebrates: Weight of evidence: Several test results are available from different independent sources. For Daphnia magna the following results are provided: 
24 h EC50 =110 mg/l
48 h EC50 = 2000 mg/L
96 h EC50 = 3100 mg/l
For the species Nitocra spinipes a 48 h EC50 of 4800 mg/l is provided.
Sublethal effects were determined with Dragonfly nymphs (several different species). Significant effects were recorded on the oxygen consumption rate and the ammonia excretion rate.

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
110 mg/L

Additional information

Short-term toxicity to aquatic invertebrates: Weight of evidence: Several test results are available. For Daphnia magna the following results are provided:

24 h EC50 =110 mg/l

48 h EC50 = 2000 mg/L

96 h EC50 = 3100 mg/l

However, no analytical monitoring was conducted during the studies Therefore, there is no evidence that the concentration of the substance was maintained during the test.

For the species Nitocra spinipes a 48 h EC50 of 4800 mg/l is provided.

Sublethal effects were determined with Dragonfly nymphs (several different species). Significant effects were recorded on the oxygen consumption rate and the ammonia excretion rate.
