Description of key information
The pyridine bases contained in the UVCB substance are not rapidly degraded by hydrolysis or photodegradation. The substance was not readily degradable in a standard test according to OECD TG 301. A number of published studies demonstrated that picolines and lutidines are biodegraded by a variety of micro-organisms present in natural surface waters or soils. More rapid degradation occurred under aerobic conditions. Nevertheless, the available biodegradation study showing no ready biodegradability and the lack of information on appropriate environmental half-lives are suggesting that the substance may be relatively persistent under environmental conditions.
The substance has a very low organic carbon-water partition coefficient and is considered as highly mobile in soil and sediment. Furthermore, the substance has no potential for bioaccumulation.
Additional information
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.
