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 1.25 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 1.25 mg/L. As the acute LC50 (96h) fish is 100 mg/l it is justified to assume that the chronic fish NOEC would be >1.25 mg/L (usual chronic to acute ratio is 1:10). In addition fish is the least sensitive species. With this assumption three chronic values (all NOEC > 1mg/L) would be 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 = 3,6, 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 = 2.6 mg/L and the registration substance is not readily biodegradable: R51/53.
Proposed classification according CLP (2nd) ATP 2011/286/EC:
no classification required as lowest chronic value NOEC reproduction (21d) daphnia is > 1 mg/L.
