Level III Fugacity Model (Full-Output):
=======================================

EPIWIN inputs:
Chem Name : 2-Propenoic acid, 2-methyl-, 2-[2-(2-ethoxyethoxy)ethoxy]ethyl ester
Molecular Wt: 246.31
Henry's LC : 3.08e-009 atm-m3/mole (calc VP/Wsol)
Vapor Press : 0.00058 mm Hg (user-entered)
Log Kow : 2.08 (user-entered)

Results and discussion

Percent distribution in media

Other distribution results:
The potential environmental distribution of Ethyltriglycol methacrylate obtained from generic level III fugacity model shows that if released to air, Ethyltriglycol methacrylate preferentially partitions to soil and to a lesser degree to water. Partitioning to air and sediment is very low. When released to water all Ethyltriglycol methacrylate tends to stay in the compartment where it was released.
The chemical is a chemical intermediate - emissions to soil are not expected.

Applicant's summary and conclusion

Conclusions:
Using a valid Fugacity modeling method (Mackay Level III) the potential environmental distribution of Ethyltriglycol methacrylate was calculated. If Ethyltriglycol methacrylate is released to air, Ethyltriglycol methacrylate preferentially partitions to soil and to a lesser degree to water. Partitioning to air and sediment is very low. When released to water all Ethyltriglycol methacrylate tends to stay in the compartment where it was released.
The chemical is a chemical intermediate - emissions to soil are not expected.
Executive summary:

Using a valid Fugacity modeling method (Mackay Level III) the potential environmental distribution of Ethyltriglycol methacrylate was calculated. If Ethyltriglycol methacrylate is released to air, Ethyltriglycol methacrylate preferentially partitions to soil (82.3%) and to a lesser degree to water (17.5%). Partitioning to air and sediment is very low. When released to water all Ethyltriglycol methacrylate tends to stay in the compartment where it was released (water compartment: 99.8%).

The chemical is a chemical intermediate - emissions to soil are not expected.
