Applicant's summary and conclusion
- Conclusions:
- 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.
- Executive summary:
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.
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).
