Description of key information
The acute toxicity of the test substance to Rainbow Trout (Salmo gairdneri) was determined in a study (BASF SE, TX 81056, 1981) according to a method equivalent to OECD 203 under non GLP conditions. After 96 hours the LC50 was determined to be 13.3 mg/L.

Additional information
The acute toxicity of the test substance to Rainbow Trout (Salmo gairdneri) was determined in a study (BASF SE, TX 81056, 1981) according to a method equivalent to OECD 203 under non GLP conditions. This study encompassed one treatment group per concentration of the test item and one replicate for the blank control and one replicate for the vehicle control. Each group contained 10 individuals. The acute toxicity to unfed juvenile Rainbow Trout (Salmo gairdneri) was determined in an aerated, semi-static, 96-hour test under 24 hours renewal conditions. Observations of mortalities and toxic symptoms were made at 24, 48, 72 and 96 hours. The nominal concentrations of the test substance were 0 (control), 1.8, 3.2, 5.6, 10, 18, 32 and 56 mg/L. No concentrations of the test substance were measured. A blank control and a vehicle control of acetone were prepared in tests solutions without the test substance. The water quality parameters (pH, dissolved oxygen, temperature and water hardness) were measured at the start and at the end of the test. There were no mortalities in either the freshwater or the acetone controls tested during the 96 hour exposure period. After 96 hours the LC50 was determined to be 13.3 mg/L.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
