Applicant's summary and conclusion
- Conclusions:
- According to the results of the Mackay Level III model (EPI Suite v4.11), BHT will mainly distribute into the compartments soil (82.9%), water (8.5%), sediment (7.2%) and air (1.3%).
- Executive summary:
The environmental distribution of BHT was estimated using the Level III Fugacity model of EPI Suite v4.11. Besides the physico-chemical properties of BHT, the model also considers the releases to the different compartments, the degradability as well as advection values characterising the exchange between the compartments. Based on the model results, BHT will mainly distribute into the compartments soil (82.9%), water (8.5%), sediment (7.2%) and air (1.3%).
