Description of key information

The acute toxicity to fish was examined in a guideline study (BASF AG, 1991) following German national standard DIN 38412, part L15 (1982) with the species Leuciscus idus. The test fish were exposed to the substance for 96 hours in a static test system. At test termination a LC50 > 10000 mg/L (nominal) was determined.

Additional information

The acute toxicity to fish was examined in a guideline study (BASF AG, 1991) following German national standard DIN 38412, part L15 (1982) with the species Leuciscus idus. The test fish were exposed to the substance for 96 hours in a static test system. The concentration of the test substance was nominal 10000 mg/L. No concentrations of the test substance were measured. At test termination a LC50 > 10000 mg/L (nominal) was determined.

Comparable results were obtained by a supporting study with the close structural analogue CAS 1324-29-4 following OECD guideline 203 with Brachydanio rerio. After the 96 hour exposure period a LC50 > 100 mg/L (nominal) was determined (Ciba-Geigy Ltd. 1989).
