Additional information

Conclusion on classification

In acute toxicity tests for the aquatic compartment on daphnia, algae, fish and microorganism all acute aquatic toxicity values L(E)C50 for the registration substance are >1 mg/L.

Fish is the most sensitive species with NOEC=6.25 mg/L and LC50=14.5 mg/l.

The registration substance is not readily biodegradable and not bioaccumulative (log Kow = 1.6, low BCF see IUCLID Chapter 5.3).

 

Short-term effects

Proposed classification according CLP:

no classification required as lowest acute LC50 is > 1 mg/L.

 

Long-term (chronic) effects

Proposed classification according CLP:

Classification Aquatic chronic 3 required as lowest acute value LC50 (96h) fish is 14.5 mg/L and the substance is not readily biodegradable.
