Description of key information

The 48 hour EL50 is >1000 mg/L WAF.

Key value for chemical safety assessment

Additional information

Eight acute invertebrate studies are available for members of this category. Six of the tests are conducted with Daphnia magna, and the remaining two with Mysidopsis bahia. There does not appear to be any difference in sensitivity between these two test species. Due to the very low solubility of the test substances all the tests were conducted using Water Accommodated Fractions (WAF). All eight studies report unbounded EL50s, i.e. that the 50% effect level was above the highest concentration tested. The six OECD style tests used higher test concentrations than the two USEPA style tests. Based on the OECD style tests we can conclude that the EL50 is >1000 mg/L WAF.
