Description of key information

In a chronic toxicity study performed with Daphnia magna (life-cycle test following OECD 202 a 21d EC50 of >1.9 and < 6.0 mg/l was estimated for both immobilization/mortality and reproduction. At a concentration of 0.6 mg/l and 1.9 mg/l the reproduction rate dropped by 4.1 and 19.8% respectively and at concentration of 6.0 - 60 mg/l live animals were no longer seen after five days.

Key value for chemical safety assessment

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

Additional information

In a chronic toxicity study performed with Daphnia magna (life-cycle test following OECD 202; pH 7.7 - 8.8; 21.8°C; semi-static, non aerated system; analysis by HPLC) a 21d EC50 of >1.9 and < 6.0 mg/l was estimated for both immobilization / mortality and reproduction. At a concentration of 0.6 mg/l and 1.9 mg/l the reproduction rate dropped by 4.1 and 19.8% respectively and at concentration of 6.0 - 60 mg/l live animals were no longer seen after five days.
