Additional information

For the three trophic levels in the aquatic compartment acute and chronic ecotoxicity data are available. The basis for the derivation of the PNEC freshwater is the ErC10 (72h) of 8.1 mg/L for algae which is the most sensitive species. Due to the very low sorption of the registration substance to sediment and soil the Equilibrium Partitioning Method was used to derive the PNEC sediment and PNEC soil. The PNEC marine water and PNEC marine sediment were derived from the corresponding PNEC freshwater respectively PNEC freshwater sediment applying an assessment factor of 10.

Conclusion on classification

For the three trophic levels in the aquatic compartment acute and chronic ecotoxicity data are available. The lowest acute value is the ErC50 (72h) algae of 10.8 mg/L and the lowest chronic value is the ErC10 (72h) alge of 8.1 mg/L. The registration substance is not readily biodegradable and not bioaccumulative (log Kow = 0).

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/EEC:

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

Long-term (chronic) effects

Proposed classification according DSD 67/548/EEC:

R52/53 as the substance is not readily biodegradable and the lowest acute EC50 is > 10 mg/Land < 100 mg/L

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

no classification required as lowest chronic value ErC10 (72h) algae is > 1 mg/L.
