The test data indicate that EMA is rapidly biodegraded and would be completely mineralized in the environment.
For the biodegradability of ethyl methacrylate the following information
OECD 301D: 79.1% degradation after 21 days. Thiebaud and Moncel (1995)
EMA is readily biodegradable. This is consistent with data available on
all members of the category of lower methacrylate esters showing that
they are also readily biodegradable.
Based on the TGD the defaults for readily biodegradable substances the
first order constants and half-life for biodegradation in surface water
for EMA is as follows:
Rate constant (surface water) ksw= 0.047 d-1(at
Half-life (surface water) [DT50] = 14 d (at 22/25 °C)
