Description of key information
The acute toxicity of the substance to the freshwater invertebrate Daphnia magna has been investigated and gave a 48-Hour EC50 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 48-hour static test conducted according to OECD Guideline 202 the acute toxicity of the substance to Daphnia magna 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 mobility of daphnia. 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. EC50 (immobilisation) > 100 mg/L.
