Additional information

Conclusion on classification

Classification relevant information:

Biodegradation: not readily biodegradable (7.7% after 28 d)

Bioaccumulation: log Pow: 1.65 at 20 °C

 

Short-term toxicity:

Fish: LC50 (96 h) = 9.7 µg a.i./L (Lepomis macrochirus)

Aquatic invertebrates: EC50 (48 h) = 206 µg a.i./L (Daphnia magna)

Algae: ErC50 (72 h) = 94 µg a.i./L (Pseudokirchnerella subcapitata)

 

Long-term toxicity:

Fish: NOEC (270 d) = 24 µg a.i./L (Pimephales promelas)

Aquatic invertebrates: NOEC (21 d) = 78 µg a.i./L (Daphnia magna)

Algae: ErC10 (72 h) = 65.8 µg a.i./L (Pseudokirchnerella subcapitata)

 

Classification according to CLP

Based on data above, the substance is not readily biodegradable (7.7% biodegradation after 28 d). Acute and chronic toxicity data are available for three trophic levels i.e. fish, algae and aquatic invertebrates. Fish were found to be the most sensitive trophic level in short-term and long-term tests with an EC50 (48 h) of 9.7 µg/L and a NOEC (270 d) of 24 µg/L. The classification and labelling is based on harmonised classification (Annex VI, Regulation (EC) 1272/2008, Index-No: 006-012-00-2 and on own hazard assessment. Therefore, the substance needs to be classified as Aquatic Chronic 1 (H410) and Aquatic Acute 1 (H400) with an M-factor of 100 according to the consolidated version of Regulation (EC) No 1272/2008 and further amendments (ATPs).
