Key value for chemical safety assessment

Additional information

The acute toxicity of 2-methyl-N-(4-sulfamoylphenyl) prop-2-enamide (SPM-N) to aquatic invertebrates was investigated in a study by Migchielsen (2008b). The test was performed according to OECD Guideline 202, under GLP conditions. Daphnia magna was exposed for 48 hours to the test material within a static water regime at 20 ± 1 °C. Analytical determination of the test concentration (limit test, 100 mg/L nominal concentration) was performed using HPLC with UV detection. No effects in daphnid mobility or any other adverse effects were reported after 48 hours, resulting in an EC50 (48 h) > 29 mg/L (measured concentration).
