Description of key information

A Daphnia magna (Crustacea, Cladocera) reproduction test was performed according to the OECD Guideline No 211 (adopted September 21, 1998) and Principles of Good Laboratory Practice (GLP, OECD 1997).
The aim of the study was the determination of the reproductive output of Daphnia magna exposed to a range of concentrations of the test substance (determination of NOEC after 21-day exposure). 5 concentrations in the range from 1.00 to 100 mg/L with separation factor of 3.2 were used. The NOEC (21-day in mg/I) is 10 mg/I while LOEC is 32 mg/L.

Key value for chemical safety assessment

EC10, LC10 or NOEC for freshwater invertebrates:
10 mg/L
