Description of key information
A study with the registered substance following the OECD guidance 202 and GLP was performed by the Ministry of Environment in Japan. The EC50 after 48h of exposure was found to be 38 mg/l. Furthermore a QSAR analysis by the Canadian authorities shows similar results for the 48h EC50, using ECOSAR models the prediction is found to be 11.17 mg/L. Ultimately the Danish QSAR database showed similar results with values of 10.842 mg/L for the 48h EC50.
