Description of key information

The EC50 for Daphnia magna ranged from 1.1 - 2.8 based on varying methods of test material application.

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
1 mg/L
EC50/LC50 for marine water invertebrates:
2 mg/L

Additional information

Three 48 hour static toxicity tests were conducted with Daphnia magna. The test material was delivered by either direct additon, with sonication, and with an acetone carrier solvent. The resulting EC50 values (based on immobility) were determied to be in the range of 1.1 - 2.8 mg/L, which was within the range of water solubility for the test material.
