Description of key information
The acute toxicity of the read across test substance to fish Leuciscus idus (L. Goldvariante) was determined according to DIN 38412 in a test performed under non-GLP conditions (BASF 80/133, 1980). The 96 hour LC50 was determined to be 0.095 mg/L based on the nominal concentrations.

Additional information
Supporting read across study (BASF 80/133, 1980)
The acute toxicity of the read across test substance to fish Leuciscus idus (L. Goldvariante) was determined according to DIN 38412 in a test performed under non-GLP conditions. This study encompassed one treatment group for the dose rates of the test item and one replicate for the control. Each group contained 10 individuals. The acute toxicity to unfed Leuciscus idus (L. Goldvariante) was determined in an aerated, static, 96-hour test. The test fish were observed at 1, 4, 24, 48 and 96 hours of test duration for sublethaI effects and mortality. Dead fish were removed at least once daily and discarded. The nominal test concentrations were 0 (control), 0.010, 0.014, 0.021, 0.031, 0.046, 0.068, 0.100, 0.147, 0.215 and 0.316 mg/L. No concentrations were measured. A reference substance (chloroacetamide) was used as positive control. The LC50 of the chloroacetamide was determined to be 28 mg/L after 48 hours. The validity criteria were met. There were no toxic effects observed in any treatment group during this test. The 96 hour LC50 was determined to be 0.095 mg/L based on the nominal concentrations.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
