Description of key information
EC 50, EC0 = 1500 mg/L
Key value for chemical safety assessment
- EC50 for microorganisms:
- 1 500 mg/L
Additional information
Based on the resutls of the published report where the biodegradability of typycal leather chemicals are degraded by activated sludge treatment, analogue substance 1 showed a good biodegradability rate, without inhibilition of the respiration rate at any dose up to 1500 mg/l over 5 days.
As a supporting study also the test on FLL sample 9 was considered that estimates no effects on the respiration of Psuedomonas putida at loading rates up to 10,000 mg/l (4900 mg/l active substance) (WAF testing approach taken). This result indicates a substance with low aquatic toxicity.
Based on the read across considerations same results apply to target substance
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.
