level III distribution was calculated using the EPI Suite™ ver. 4.10
(US-EPA, 2008) for releases of the methacrylate esters to air and water,
but not soil, because there are no direct emissions to soil. The Mackay
III calculations result in the following theoretical partitioning into
the standard compartments.
Mackay level III Calculation
Release to air
Release to water
When released to air, Ethyltriglycol methacrylate preferentially
partitions to soil and to a lesser degree to water. Partitioning to air
is very low and no partitioning is found to sediment .When
released to water all Ethyltriglycol methacrylate tends to stay in the
compartment where it was released.
Ethyltriglycol methacrylate has a low vapour pressure and a high water
solubility and consequently a low Henry constant. Epiwin model
calculations indicate a low volatilisation potential.
Further studies does not need to be conducted as the substance is
readily biodegradable (experimental result please see chapter 5.2.1.
(biodegradation screening test according to OECD 301 F, manometric
respiratory test), 90.1 % biodegradation was obtained after 28 days.
Therefore Ethyltriglycol methacrylate is classified as readily
biodegradable. The 10-day criterion for ready biodegradability was met.,
