The potential environmental distribution of BDGMA obtained from a generic level III fugacity model under two emission scenarios is shown in the table. 

The results show that if BDGMA is released into air, it mainly distributes to soil. A smaller amount partitions to water or remains in the air. If the substance is released into water, it mainly remains in water. The substance does not have a significant presence in sediment or air.

Applicant's summary and conclusion

Conclusions:
The environmental distribution (Mackay level III distribution) of BDGMA has been modelled using EPIWEB version 4.1.
The results show that if BDGMA is released into air, it mainly distributes to soil. A smaller amount remains in the air or partitions to water. If the substance is released into water, it mainly remains in water. The substance does not significantly partition to sediment.
