Additional information

The test was performed according to OECD 209 (1984). Since at the highest tested concentration only the 0.2 % of population resulted to be inhibited, the test item can be considered as not inhibitory against waste water bacteria. Nevertheless, as the duration of the test was 30 minute (against 3 hours according to OECD) despite the substance is stable (not ready degradable), in order to derive the STP PNEC the abovementioned EC50 value has been used, following a conservatively approach.
