Description of key information
The growth inhibition on aquatic plants according to REACH Annex VII (9.1.2, column 2) was investigated by testing the effect on the growth of Lemna gibba following OECD 221. This study covers both IUCLID5 endpoints, section 6.1.5 and 6.1.6. A further test on the growth inhibition of algae according to OECD guideline 201 is thus not required. For the groth inhibion test on Lemna gibba, the EC50 based on growth rate of dry weight were determined to be 10.7 mg/L (nominal concentration).
