EC number: 201-297-1
CAS number: 80-62-6
Biodegradation: Methyl methacrylate is readily biodegradable in OECD
screening test OECD 301 C: 94 % biodegradation within 14 days.
Abiotic degradation by hydrolysis under environmental conditions of
methyl methacrylate is low
Bioaccumulation: log Pow of methyl methacrylate is 1.38, therefore
bioaccumulation of methyl methacrylate is not expected.
Adsorption to soil and sediment is low due to log log Pow.
In water methyl methacrylate will be rapidly biodegraded, abiotic
degradation by hydrolyses is not of major concern. From the water
surface the test substance will evaporate slowly into the air. After
exposure to the air methyl methacrylate will be rapidly degraded by
photochemical processes. Based on a log Pow of 1.38, bioaccumulation of
methyl methacrylate is not expected. Due to the low logKoc for different
soil types adsorption to the solid soil phase of methy methacrylate is
unlikely. Furthermore, based on a Mackay Level 1 calculation the
substance will mainly partition to air (ca. 91.5 %) in this equilibrium
model. In the Mackay Level III model, which additionally takes into
account transport and degradation processes. MMA, when released to
air or water, will predominantly remain in the environmental compartment
into which it was released (air: 94.8 %; water: 98.5 %).
