Level III Fugacity Model (Full-Output):
=======================================
Chem Name : 2-Propenoic acid, 2-methyl-, isodecyl ester
Molecular Wt: 226.36
Henry's LC : 0.0175 atm-m3/mole (calc VP/Wsol)
Vapor Press : 0.0117 mm Hg (user-entered)

Results and discussion
Percent distribution in media
- Other distribution results:
- The potential environmental distribution of Isodecyl methacrylate obtained from generic level III fugacity model under two emission scenarios is
shown in the table.
The results show that if Isodecyl methacrylate is released mainly into air, it mainly remains in the air. And if it is released into water, it also mainly
remains in the water. Isodecyl methacrylate is predicted to partition to a small degree into soil and sediment.

Applicant's summary and conclusion
- Conclusions:
- Using a valid modeling method, if Isodecyl methacrylate is released into air, it mainly remains in the air; if it is released into water, it mainly remains in the water. Isodecyl methacrylate is predicted to partition to a small degree into soil and sediment.
- Executive summary:
Using a valid modeling method, if Isodecyl methacrylate is released into air, it mainly remains in the air; if it is released into water, it mainly remains in the water. Isodecyl methacrylate is predicted to partition to a small degree into soil and sediment.
