Description of key information

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
42 mg/L

Additional information

Test data

Two acute tests have been carried out with the invertebrate species Daphnia magna.

One of the tests (L'Haridon, 2002b) was conducted over a range of test concentrations, was supported by analysis of exposure concentrations and was subject to GLP. The test gave a 48-hour EC50 value of 42 mg/l. This result provides a suitable basis for deriving a PNECwater.

QSAR's

An estimated value of 81 mg/l has been derived for acute (48-hour LC50) toxicity to invertebrates using an ECOSAR QSAR applicable to esters. The value is consistent with those obtained in the reported studies.
