Description of key information
In a 96h static acute toxicity to fish test onOncorrhynchus mykiss(rainbow trout), the EC50 value for the test substance BMS 233110-01, was 17.69 mg/l. The NOEC was >12.5 mg/l.
In a 48h acute aquatic toxicity test onDaphnia magna, the EC50 value for the test substance BMS 233110-01, was 30.34 mg/l. The NOEC was 12.5 mg/l.
BMS 233110-01 resulted in a EbC50 (72 hours) of 4.3 mg/l and a ErC50 (0-72 hours) of 5.68 mg/l in Selenastrum Capricornutum, Strain No. CCAP 278/4. The NOEC was considered for growth rate and biomass was 1.98 mg/l.
BMS 233110-01 had no biologically significant inhibitory effect on the respiration rate of activated sludge at 100 mg/l. The highest concentration tested was1000mg/l which resulted in a inhibition of 16% however as this was the highest concentration the EC50 would be considered to be greater than 1000 mg/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.
