Conclusion on classification

Aquatic acute toxicity

48 h, EC50 (Daphnia magna): 706 µg/L (time weighted average test concentration)

72 h, ErC50 (Pseudokirchneriella subcapitata): > 249 µg/L (geometric mean measured test concentration)

Aquatic chronic toxicity

72 h, ErC10 (Pseudokirchneriella subcapitata): > 249 µg/L (geometric mean measured test concentration)

72 h, NOEC (Pseudokirchneriella subcapitata): 18.6 µg/L (geometric mean measured test concentration)

Biodegradation: not readily biodegradable: 29 % after 28-days (Manometric Respirometry Test, OECD 301 F)


Classification according to CLP

The available experimental test data are reliable and suitable for classification purposes under Regulation (EC) No 1272/2008. The test substance was found to be not readily biodegradable under the test conditions. The most sensitive test for the aquatic compartment was the acute toxicity test to Daphnia magna which revealed a 48 h EC50 of 706 µg/L. The algal growth inhibition test with Pseudokirchneriella subcapitata revealed a 72 h NOEC of 18.6 µg/L. Based on these results, the substance is to be classified for short-term (acute) aquatic toxicity (Aquatic Acute 1, M-Factor: 1) and for long-term (chronic) aquatic toxicity (Aquatic Chronic 1, M-Factor: 1) according to Regulation (EC) No 1272/2008 (CLP), as amended for the seventeenth time in Regulation (EU) 2021/849.
