Conclusion on classification

Conclusion on classification

Degradation

Biodegradation: Not readily biodegradable: 0% after 28 d (O2 consumption, OECD 301 D)

 

Bioaccumulation

Log Kow: 2.43 to 2.9 (at 22.8 °C) for the two isomers of the substance (EU Method A.8, HPLC method)

 

Aquatic acute toxicity

Fish: 96 h, LC50 (Danio rerio): 35.4 mg/L (nominal)

Aquatic invertebrates: 48 h, EC50 (Daphnia magna): 284 mg/L (nominal)

Algae: 72 h, ErC50 (Pseudokirchneriella subcapitata): 130 mg/L (nominal)

 

Aquatic chronic toxicity

Fish: no data available
Aquatic invertebrates: no data available

Algae: 72 h, ErC10 (Pseudokirchneriella subcapitata): 61.4 mg/L (nominal)

 

Classification according to CLP

Acute toxicity data are available for all three trophic levels whereas chronic data are only available for algae. The test substance is not considered to be rapidly degradable and has a low potential for bioaccumulation. Fish was found to be the most sensitive species with a LC50 (96 h) of 35.4 mg/L. Thus, the test substance needs to be classified and labeled as “chronic category 3” (H412) according to the 6th ATP of Regulation (EC) No 1272/2008 (CLP).
