Applicant's summary and conclusion
- Conclusions:
- The data on environmental distribution of ethylbenzene obtained from the level III fugacity model suggest that ethylbenzene will not persist in the environment and depending on various emission scenarios, approx. 70% of ethylbenzene will be degraded by both biotic and abiotic mechanisms and approx. 30% will be physically removed (advected) from the environment.
