Description of key information

o-Toluidine could not be removed after 150 days in a landfill environment under anaerobic conditions. 

Key value for chemical safety assessment

Additional information

The degradability of 19 organic chemicals (BTEX, chlorinated aliphatic compound, nitroaromatic compounds and anilines) in a landfill environment was studied using different test systems designed to focus on degradation and to avoid or account for loss of chemicals by sorption to the waste, by volatilization to the gas phase and/or by leaching. The test systems used were reactors installed in a leachate well at an actual landfill, reactors submerged in an artificial leachate well in the laboratory and laboratory batch reactors.

o-Toluidine could not be removed after 150 days in a landfill environment under anaerobic conditions. The test was not performed according to current standard methods and represent only special circumstances, but indicates that the substance is not degradable under anaerobic conditions.
