Additional information

The following set of different results are available for such PNEC aquatic assessment: three short term studies available covering three trophic levels (daphnia, algae and fish) and two long term testing on the same trophic levels (Daphnia and Fish). The lowest LC50 or 10 and NOEC values are the following

Short term studies :EC50(48 h): 2.7 mg/Lfrom the daphnia study

Prolonged term studies :NOEC (28 d): >= 4.09 mg/Lfrom the daphnia study

The mentioned value were therefore used in PNECaquatic assessment
