Description of key information

LC50 (96 h) > 29 mg/L (measured concentration)(Cyprinus carpio, OECD 203)

Key value for chemical safety assessment

Additional information

One study evaluating the acute toxicity of 2-methyl-N-(4-sulfamoylphenyl) prop-2-enamide (SPM-N) to fish species is available (Migchielsen, 2008a). This study was conducted according to OECD Guideline 203, under GLP conditions. Cyprinus carpio was exposed to the test material in a limit test (100 mg/L nominal concentration) for 96 hours at 21 ± 2 °C. Analytical determination of the test concentration was performed using HPLC from samples collected at test start and after 96 h. After the exposure period, no mortality or any other adverse effects were observed and therefore the LC50 (96 h) was determined to be > 29 mg/L (measured concentration).
