Description of key information
In a 96h static acute toxicity to fish test on Oncorrhynchus mykiss (rainbow trout), the LC50 value for the test substance BMS 217947 -01, was 8.4 mg/l. The NOEC was 1.9 mg/l.
In a 48h acute aquatic toxicity test on Daphnia magna, the LC50 value for the test substance BMS 217947 -01, was 29 mg/l. The NOEC was 0.91 mg/l.
BMS 217947-01 inhibited the growth of Selenastrum Capricornutum, Strain No. CCAP 278/4 at concentrations tested in excess of 0.99mg/l under the conditions of this test. The EbC50 (72 hours) was 9.7mg/l and the ErC50 (0-72 hours) was 32mg/l.
BMS 217947-01 had no biologically significant inhibitory effect on the respiration rate of activated sludge at 100mg/l, the highest concentration tested. The EC20, EC50 and EC80 of the test substance could not, therefore, be calculated but these must be greater than 100mg/ml, the highest level tested.
Based on the above, the substance is classified for Chronic aquatic toxicity, category 2.
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
