Description of key information
The acute toxicity of the substance to the freshwater fish Rainbow trout (Oncorhynchus mykiss) has been investigated and gave a 96-Hour LC50 of greater than 100 mg/l. Correspondingly the No Observed Effect Concentration was 100 mg/l.
Key value for chemical safety assessment
Additional information
In a 96-hour semi-static test conducted according to OECD Guideline 203 the acute toxicity of the substance to Oncorhynchus mykiss was examined (Safepharm 2001). According to the results of the range-finding test, a definitive limit-test was performed in a closed system at a nominal concentration of 100 mg/L. The effect-concentration was based on the mortality of fishes. The test substance being highly instable due to its high hydrolysis potential, the effect-concentration was related to the nominal concentration. The test was performed with an aqueous solution of the test substance. LC50 > 100 mg/L.
