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

The results show that if TREGDMA 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.

 

Applicant's summary and conclusion

Conclusions:
The environmental distribution (Mackay level III distribution) of TREGDMA has been modelled using EPIWEB version 4.1.
The results show that if TREGDMA 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.
