Conclusions:
Based on the EPI Suite ECOSAR version 1.10 prediction model, the 96 hours LC50 was estimated to be 93.634 mg/l on Fish for substance N-(2-phenoxyphenyl)methanesulfonamide (CAS no.51765-51-6 ) on the basis of mortality effects.
Executive summary:

Based on the prediction done using the EPI Suite ECOSAR version 1.10, the 96hr toxicity on fish was predicted for test substance N-(2 -phenoxyphenyl)methanesulfonamide (CAS: 51765 -51 -6). On the basis of effects observed in a static freshwater system, the lethal concentration LC50 value for the substance is estimated to be 93.634 mg/l . Based on this value, the test chemical can be considered to be classified in aquatic chronic category 3 as per the CLP classification criteria.
