Description of key information
The 96-hour LC50 value for the test item and rainbow trout was estimated to be >100 mg a.i./L. The No-Observed-Effect Concentration (NOEC) was determined to be 100 mg a.i./L.
Key value for chemical safety assessment

Additional information
The purpose of this study according to OECD TG 203 was to estimate the acute toxicity of the test item to rainbow trout (Oncorhynchus mykiss) under static test conditions. The test was conducted as a limit test with a nominal concentration of 100 active ingredient per litre of test solution (mg a.i./L). During the definitive exposure period, one water sample was removed from each replicate solution of the treatment level and the control at 0 and 96 hours for the analysis of test item concentration.All exposure solution and QC samples were analyzed for the test item using a gas chromatographic (GC) procedure. Following 96 hours of exposure, no mortality or sublethal effects were observed among organisms exposed to the 100 mg a.i./L treatment level or the control. Based on these data, the 96-hour LC50 value for the test item and rainbow trout was empirically estimated to be >100 mg a.i./L. The No-Observed-Effect Concentration (NOEC) was established to be 100 mg a.i./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).
