Additional information

Conclusion on classification

The following key information was used for the environmental classification:

Lowest E(L)C50 value 0.54 mg/L to Daphnia magna (Anai, 2011)

Not ready biodegradable in an OECD 301C test (Mizuguchi, 2010)

Highest BCF (of several constituents): 584 (Murakami, 2011)

GHS:

As the lowest EC50 value (to Daphnia magna) was ≤1 mg/L, the substance has to be classified in the Category Acute 1 with H400.

As the lowest EC50 value (to Daphnia magna) was ≤1 mg/L and the substance is not ready biodegradable and the substance has a BCF of ≥500, the substance has to be classified in the Category Chronic 1 with H410.

DSD:

As the lowest EC50 value (to Daphnia magna) was ≤1 mg/L, the substance is not ready biodegradable and the BCF>100, the substance has to be classified as N, R50/53.
