Key value for chemical safety assessment

Additional information

As key study a static GLP-study according to OECD 203 and EU method C.1 regarding the acute toxicity to fish was identified. It was performed as an advanced limit test with two test concentrations of 50 and 100 mg/L plus control (BASF, 1995; project no. 17F0349/945078). After 96h of exposure a NOEC of 100 mg/L and a LC50 of > 100 mg/L was estimated, related to nominal concentration. The measured concentrations ranges between 96 - 102 % of the nominal concentrations. It can be concluded that the substance is with high probability not harmful to fish.
