Description of key information

The EC10  (21d) reproduction was determined to be 1.69mg/L (loading rate/WAF) 

Key value for chemical safety assessment

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

Additional information

In a chronic toxicity test on Daphnia magna reproduction according to OECD 211 the UVCB substance was investigated at saturation concentration (BASF 2016). As the test substance is a UVCB substance which is sparingly soluble in water, the test solution was prepared following general guidance provided in OECD 23 in order to generate a water accommodated fraction of the test substance in test medium (undiluted filtrate up to a loading rate of 10 mg/L). A clear relationship between loading rates of the WAFs and reproduction of the daphnids was determined in this test. However, the EC10 reproduction after 21 days was determined to be > 1mg/L.
