Additional information

The PNEC freshwater, marine waters, and intermittent release was derived based on the data on acute aquatic toxicity and on chronic aquatic toxicity where available following the guidance (GIRCSR Section 10, ECHA 2008). If combination of studies with confirmed EC50 values or NOECs and limit tests was available for one taxonomic groups, preference was given to the data with confirmed (no) effect concentrations. In the absence of a confirmed (no) effect concentration from testing of one of species of the three trophic levels, the lowest confirmed (no) effect concentration of the other species was used to derive the PNEC.

Conclusion on classification

There were no effects observed up to 100 mg/l (nominal) in any acute aquatic toxicity testing. These results do not warrant classsification according to GHS EU implementation.
