Any other information on results incl. tables

Several EC50 values forDaphnia magna were determined and reported. EC50s in Daphnia ranged from 42 mg/L (IPCS, EHC 167), 48.2 mg/L (Pesticide Ecotoxicity Database) to 48.3 mg/L (Water Pollut. Control Fed.).

Validity criteria fulfilled:
not specified
Conclusions:
An EC50 (48-h, immobilization) of 48.3 mg/L, under static conditions was determined for Daphnia magna.
Executive summary:

Several EC50 values for Daphnia magna were determined and reported. EC50s in Daphnia ranged from 42 mg/L (IPCS, EHC 167), 48.2 mg/L (Pesticide Ecotoxicity Database) to 48.3 mg/L (Water Pollut. Control Fed.).

The EC50 (48-h, immobilization) value of 48.3 mg/L, under static conditions will be used for the key study because most of the study design data are reported and the value is in the range with the other puplished data.

These data and information are based on different publications and the International Programme on Chemical Safety (IPCS) published under the joint sponsorship of the United Nations Environment Programme, the International Labour Organisation, and the World Health Organization (Environmental Health Criteria 167).
