Additional information

Conclusion on classification

Acute aquatic toxicity data is available for 3 trophic levels (fish, aquatic invertebrates and aquatic algae). An acute effect value of 0.1-1 mg/L is determined for both aquatic invertebrates and algae. Chronic data are available for 2 trophic levels (fish, aquatic invertebrates and aquatic algae). The lowest chronic effect value is a 21-d EC10 of 0.0063 mg/L as observed in daphnids. In addition, the substance is readily biodegradable and has a log Kow of >4. Based on all this information the substance needs to be classified as Aquatic Acute 1, H400 (Very toxic to aquatic life) and as Aquatic Chronic 1, H410 (Very toxic to aquatic life with long lasting effects) according to regulation EC/1272/2008 (CLP). The M-Factor is 1 based both on the available acute and chronic effect values.
