Conclusion on classification

Aquatic acute toxicity:


96 h, LC50 (Oncorhynchus mykiss): 11 mg/L (Mean measured)


48 h, EC50 (Daphnia magna): 5.4 mg/L (95 % CI = 4.4 – 6.3 mg/L) (Mean measured)


72 h, ErC50 (Pseudokirchneriella subcapitata): 37.2 mg/L (Mean measured)


 


Aquatic chronic toxicity:


35-d, NOEC (Danio rerio) = 0.509 mg/L (Mean measured)


35-d, EC10 (Danio rerio) = 0.390 mg/L (EC10 < NOEC based on confidence limit CL: 0.147 – 0.645 mg/L), (Mean measured)


21-d, NOEC (Dapnia magna) = 0.161 mg/L (Mean measured)


21-d, EC10 (Daphnia magna) = 0.190 mg/L (Mean measured)


72 h, ErC10 (Pseudokirchneriella subcapitata): 6.74 mg/L (Mean measured)


Biodegradation: not readily biodegradable: 4 % after 28 days (Biological Oxygen Demand, OECD 301 C)


Partition coefficient: log Kow = 1.4 at 25 °C


Classification according to CLP


 


The available experimental 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 toxicity test to Daphnia. This study revealed a 21-d NOEC of 0.161 mg/L for reproduction. Based on these results, the substance is not classified for short-term (acute) aquatic toxicity but is self-classified for long-term (chronic) aquatic toxicity Cat. 2 according to Regulation (EC) No 1272/2008 (CLP), amended for the seventeenth time in Regulation (EU) 2021/849. However, the substance is harmonized classified in Annex VI of the CLP regulation for Acute aquatic toxicity Cat. 1 (H400) and for long-term (chronic) aquatic toxicity Cat. 1 (H410). The official classification is based on the RAC opinion (March 15th 2019) which took the aquatic studies performed on the degradation product carbendazim into consideration as relevant for the classification of the parent compound due to its rapid conversion to carbendazim (up to ca 80 % in one week in aquatic test systems).
