Description of key information
Additional information
Three studies were carried out to assess the biodegradation properties of the test item. In the key study, the ready biodegradability of the test item was determined with a non adapted activated sludge in the Manometric Respirometry Test for a period of 28 days. The study was conducted according to OECD guideline 301 F. 5-Ethyl-2-methylpyridine showed a mean biodegradation rate of 2% (ThOD NH4) and 1.5% (ThOD NO3) and is considered to be not readily biodegradable.
In the supporting study ready biodegradation was tested according to OECD Guideline 301 E (Ready biodegradability: Modified OECD Screening Test). The test item was determined ready biodegradable, but failing the 10-day window. In a supporting study according to OECD 302 B (Zahn-Wellens test) the test item showed inherent biodegradation, with 98.7 % degradation in 21 days.
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.
