Description of key information
After evaporation or exposure to the air, Methyl acrylate will be slowly degraded by photochemical processes.
Calculated half-life for a 24-hr day and 0.5E+06 OH/cm3: 40.9 hr
Key value for chemical safety assessment
Additional information
There are no experimental data on photodegradation of methyl acrylate. According to Q(SAR) data using SRC AOP v1.92, MA will be slowly degraded by photochemical processes after exposure to the air reacting with the photochemically produced hydroxyl radicals and with ozone (calculated half-life for a 24-hour day and 0.5E06 OH/cm3: 40.9 hours (= 1.7 days); for a 24-hour day and 7E11 O3/cm3: 6.55 days) (BASF SE, 2008). Since MA shows a vapour pressure of 90 hPa at 20.1 °C and a Henry's Law constant of 9.3 Pa*m3/mol, slow evaporation from the water surface can be expected. Thus, photodegradation may play a considerable role under environmental conditions.
