Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable

Additional information

Ready biodegradability of 2-methoxyethyl acrylate was investigated in one study (MITI, 1999) according to OECD guideline 301 C under GLP conditions. The applied inoculum was a mixture of activated sludge from 4 sewage treatment plants, freshwater from 3 rivers and 1 lake, and marine water and marine sediment from 2 bays in and around Japan. 100 mg substance per litre were incubated for 28 days. Based on O2 consumption, DOC removal and test material analysis, 2- methoxyethyl acrylate reached 83, 95 and 100% degradation, respectively. Hence, the substance can be considered as readily biodegradable according to the OECD requirements.
