2.2 mg/L

Additional information

A Daphnia reproduction study was conducted according to OECD 202 but included reproduction for 21 days rather than 14 days, found that the 21 day 50% lethal concentration (LC50) in parental Daphnia magna was found to be >10 mg/L, whilst the 21 day 50% reproduction inhibition concentration (ErC50) was 7.5 mg/L (95% confidence interval 4.6 -10mg/L). The maximum no-observed-effect concentration (NOECr) was 2.2 mg/L and the lowest-observed-effect concentration (LOECr) was 4.6 mg/L.

Even if higher concentration could have been tested, the test has been carried out with concentrations allowing long-term exposures and is therefore considered as valid.
