Results and discussion
Percent distribution in media
- Other distribution results:
- The potential environmental distribution of ethyl methacrylate obtained from generic level III fugacity model under two emission scenarios is shown in the table.
The results show that if ethyl 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. Very little is predicted to be partitioning into soil and sediment.

Applicant's summary and conclusion
- Conclusions:
- Using a valid modeling method, if ethyl methacrylate is released into air, it mainly remains in the air; if it is released into water, it mainly remains in the water. Very little is predicted to be partitioning into soil and sediment.
