Reference
Description of key information
The average percentage of degradability based on biochemical oxygen demand (BOD) over the 28-day exposure period was 11%.
2-(Allyloxymethyl) acrylic acid methyl ester was concluded not to be readily biodegradable under the test conditions.
The average transformation rate of 2-(Allyloxymethyl) acrylic acid methyl ester to 2-(Allyloxymethyl) acrylic acid was 108%.
Key value for chemical safety assessment
Additional information
A ready biodegradability screening test was conducted (Mitsubishi Chemical Medience Corporation, 2011, Study A110354) to assess the potential for 2-(Allyloxymethyl) acrylic acid methyl ester to be degraded by microorganisms over a 28 -day period. The study was performed according to Japanese test guidelines and in compliance with GLP.
The average percentage of degradability based on biochemical oxygen demand (BOD) over the 28-day exposure period was 11%, so 2-(Allyloxymethyl) acrylic acid methyl ester was concluded not to be readily biodegradable under the test conditions. Despite low BOD (11%), the disappearance rates of the residual amount of the 2-(Allyloxymethyl) acrylic acid methyl ester were calculated to be 99% or greater. This suggests that the most of the 2-(Allyloxymethyl) acrylic acid methyl ester is transformed.
It has been reported that hydrolysis of the ester bond of the test item generates 2-(Allyloxymethyl) acrylic acid and methanol. According to the results of the quantitative determination of 2-(Allyloxymethyl) acrylic acid, the average transformation rate was 108%. Methanol is judged to be readily biodegradable and it was estimated to have been degraded by activated sludge.
