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.
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.
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:
Long-term (chronic) effects
classification required as the lowest acute toxicity value is EC50 (48h)
Daphnia = 2.6 mg/L and the registration substance is not readily
no classification required as lowest chronic value NOEC reproduction
(21d) daphnia is > 1 mg/L.
