Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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

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.
