Description of key information

In the key study a 48-h EC50 value of >100 mg/L was established (Morrissey 1979).

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
100 mg/L
EC50/LC50 for marine water invertebrates:
100 mg/L

Additional information

The results of the key study are confirmed by the other available studies (Yasushi 2004, Bringmann 1982). In addition the test substance appeared to be not toxic when tested in the marine environment (EC50 > 100 mg/L). The species tested were Limnoria and Teredo diegensis. This provides indications that the EC50 for marine organisms is comparable to that for fresh water invertebrates.
