Additional information

Daphnia is the most sensitive species in acute and chronic aquatic ecotoxicity tests. Therefore the PNEC freshwater is derived from the chronic NOEC 21d Daphnia of 2 mg/L.

Conclusion on classification

All acute and chronic aquatic toxicity values L(E)C50 for the registration are >1 mg/Land the lowest chronic value is the NOEC reproduction (21d) daphnia of 2 mg/L. All three chronic values have a NOEC > 1mg/L) and this is the basis for the environmental classification under CLP 2nd ATP 2011/286/EC.

The registration substance is not readily biodegradable and not bioaccumulative (log Kow = 1.1, low BCF see IUCLID Chapter 5.3).

Short-term effects

Proposed classification according DSD 67/548/EEC:

no classification required as lowest acute EC50 is > 1 mg/L

Proposed classification according CLP (2nd) ATP 2011/286/EC:

no classification required as lowest acute EC50 is > 1 mg/L

Long-term (chronic) effects

Proposed classification according DSD 67/548/EEC:

classification required as the lowest acute toxicity value is EC50 (48h) Daphnia = 11.8 mg/L and the registration substance is not readily biodegradable: R52/53.

Proposed classification according CLP (2nd) ATP 2011/286/EC:

no classification required as lowest chronic value NOEC reproduction (21d) daphnia is > 1 mg/L.
