Description of key information

LC50 (96h, Oncorhynchus mykiss) >77.3 mg/l (geam. mean, corresponding to nominal 100 mg/l)

Key value for chemical safety assessment

Additional information

The test was performed according to OECD guideline 203 (1992).

The samples taken from the vessels with the nominal concentration of 21 and 100 mg/l showed a decrese of test item content (i.e. 18.7 and 77.3 mg/l, respectively), after the renewal of 48 hours. This reduction was caused by sedimentation of the substance.

The 96-hour NOEC (highest tested concentration without toxic effects after the 96 hours exposure period) and the 96-hour LC0 to Rainbow trout was determined to be higher than 100 mg test substance/l (mean measured test substance concentration: 77.3 mg/l).
