Description of key information
The study was performed according to OECD test guidelines no. 203 on rainbow trout (Oncorhynchus mykiss) under semi-static exposure conditions. Groups of seven juvenile fish were exposed to Benzethoniumchloride, dissolved in water at nominal concentrations of 0.427, 0.939, 2.07, 4.55 and 10 mg/l. The 96h-LC50 value was estimated to be 1.15 mg/l (95% confidence limits of0.757 and 1.73 mg/l); the No Observed Effect Concentration (NOEC) was found to be 0.349 mg/l.
