Additional information

Based on the results of a static test with the zebrafish (Danio rerio) following OECD 203, the 96h LC50 was determined to be 1.5 mg/L (nominal, geom. mean; BASF AG, 1998, report no. 17F0405/915125). The test was performed under GLP, the validity criteria were fulfiled.

The test concentrations were analytically monitored. The initially detected concentrations were in the range of 0.0 - 14.0% and after about 96 hours at 0.0% of the nominal concentrations. Based on a mean initial recovery of 9.4%, the 96-h LC50 was estimated to be 0.14 mg/L.

However, based on expert judgement (BASF SE, 1995) the target item is concluded to decompose in aqueous media; therefore the evaluation is based on nominal values (96h LC50 = 1.5 mg/L).
