Additional information

Justification for classification or non-classification

According to the CLP Regulation (EC 1272/2008), the threshold of classification of a substance for acute aquatic toxicity is 1 mg/l. This limit is compared with LC50 (96h) for fish, EC50 (48 h) for daphnia and EC50 (72 - 96 h) for algae or aquatic plants.

As for chronic toxicity, in case of lack of chronic data, the toxic potential is identified by appropriate combinations of acute toxicity data and lack of biodegradability. The threshold of classification is 100 mg/l.

In case of poorly soluble substances, the threshold for classification is identified as the solubility limit of the substance.

Based on LC50 and EC50 values obtained, no classification for acute toxicity was applied nevertheless; based on the EC50 (48h) of 1.08 mg/l for immobilisation effects in daphnids, the substance is classified as Aquatic Chronic Toxicity 2 for chronic toxicity according to the CLP Regulation (EC 1272/2008).
