- 130 mg/L
Additional information
The influence of the test item reaction mass containing six benzylated amine silanes on the respiration rate of activated sludge was investigated according to OECD 209, EU Method C.11 and GLP standards (2004). The nominal concentrations tested were 10, 32, 100, 320 and 284 mg/l. After the incubation period of 3 hours, the test item had no significant inhibitory effect (< 15%) on the respiration rate of activated sludge up to a concentration of 100 mg/L. At the higher test item concentrations of 320 and 1000 mg/L, significant effects of 32.3 and 70.7%, respectively, were noted. The EC50 (3 h) was determined to amount 569 mg/L and the NOEC (3 h) was 130 mg/L.
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.
