Description of key information
Biodegradation in water: screening tests
In a Manometric Respiratory Test according to OECD TG 301 F the substance was found to be toxic towards microorganisms of activated sludge (0 % biodegradation after 14 days based on ThOD). It was not possible to mitigate the toxic effects when following the recommendations of the guidelines OECD TG 301 and ISO10634 (reference 5.2.1-1). Following a worst case approach, the substance is considered to be not readily biodegradable based on its inhibitory effect to aquatic microorganisms.
