Additional information
The key study describes the acute toxicity of the test substance to carp based on OECD and EU guidelines. Ten fish per concentration were exposed for a maximum of 96 hours in a semi-static system to a concentration range from nominally 5.6 to 56 mg/L. Tween 80 was added to the test solution at a concentration of 0.1 mg/L. The test media were renewed every 24 hours.
The LC50 value calculated from the data was 24 mg/l. With 0% mortality at 18 mg/l and 100% mortality at 32 mg/l (the limits of the 95 confidence interval) and it was already reached after 2 hours following the start of the test. Effects other than mortality were exclusively observed in the fish exposed to 10 and 18 mg/l. These effects recorded were hypoactivity and loss of equilibrium.
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).
