Additional information

Acute and chronic for all three trophic aquatic levels, a sediment and soil ecotoxicity values for all three trophic levels are available.

Lowest acute aquatic ecotoxicity:       Algae ErC50 (72h) 20 µg/L

Lowest chronic aquatic ecotoxicity:    Algae ErC10 (72h) 4 µg/L

Lowest chronic sediment ecotoxicity: Nematode NOEC reproduction (3d) 1000 mg/kg dw

Lowest chronic terrestrial ecotoxicity: Soil microorganisms NOEC respriation (28d) 37 mg/kg dw.

Conclusion on classification

The registration substance is readily biodegradable and not bioaccumulative. Acute and chronic aquatic ecotoxicity values < 1 mg/L and the lowest chronic aquatic ecotoxicity value is 4 µg/L. Based on these data the following conclusion on classification applies:

Classification according 2nd ATP of CLP 2011/286/EU

Acute (short-term) aquatic hazard: Category Acute 1, H400, M factor 10

Long-term aquatic hazard: Category Chronic 1, H410, M factor 1

Classification according 67/648/EEC

N, R50/53
