Description of key information
A study regarding the removal of heterocylclic nitrogen compounds from a wastewater treatment plant showed that 3,5-lutidine was not detected in the treatment plant effluent.
Key value for chemical safety assessment
Additional information
In the supporting study conducted by Melcer et. al. (1995), the average mass flow rate of 3,5-dimethylpyridine (3,5-lutidine) into the Hamilton Woodward Treatment Plant (influent) was 0.019 kg/d and the average mass flow rate of 3,5-dimethylpyridine out of the plant (effluent) was 0.000 kg/d. Therefore, it can be concluded that the normal operations of the publicly owned treatment works (POTW) Hamilton Woodward Plant successfully degraded 3,5-dimethylpyridine to the point that it was not detected in effluent leaving the plant. The results of this study support the conclusion that 3,5-dimethylpyridine is degraded in a conventional activated sludge treatment facility designed for dry weather flow with 10% industrial sources with average influent amounts of 0.019 kg/d, such that 3,5-dimethylpyridine was not detected in treatment plant effluent.
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.
