Description of key information

Additional information

In a ready biodegradability test (performed according to the OECD 301D guideline) the registered substance achieved a total degradation of 4% after 28 days and therefore cannot be considered to be "readily biodegradable" in activated sewage sludge.

The registered substance is inherantly degradable in the aqueous environment and is expected regrade rapidly in both aerobic and anerobic conditions (Aerobic conditions: 91% in 17 days; Bouwer et al, 1985, Anaerobic conditions: 99% in less than 2 weeks; Bouwer et al, 1988). Similar rates have been observed for degradation in soil (Aerobic and Anaerobic: 90% at 4 days and greater than 90% at 22 days; Steinberg et al, 1987). Therefore it is considered that the substance is not persistane in the environment.
