Description of key information

In a 96h semi static acute toxicity to fish test in Cyprinus carpio, the EC50 value for the test substance BMS 587172 -01, was >0.011 mg/L. There were no effects at the limit of solubility.

In a 48h acute aquatic toxicity test in Daphnia magna with the test substance BMS 587172 -01, resulted in a EC50 value for daphnia magna, of 0.2mg/L based on the mean measured test concentrations. The NOEC was 0.007 mg/L.

Exposure to BMS 587172 -01 resulted in a EbC50 (72 hours) and a ErC50 (0-72 hours) of >0.098 mg/L in Selenastrum Capricornutum, Strain No. CCAP 278/4 based on a geometric mean measured value. The NOEC was determined to be >0.098 mg/L. These values were greater than the water solubility for the test.


BMS 587172 -01 had no biologically significant inhibitory effect on the respiration rate of activated sludge at 1000 mg/L. The No Observed Effect Loading Rate (NOELR) after 3 hours exposure was 1000 mg/L and the ELR50 was > 1000 mg/L.

Based on the above, the substance is classified for the environment based on the effects seen just below the limit of solubility for the Daphnia Magna
