In the model dibenzyl ether is treated as a type 1 chemical, i.e. the chemical partitions into all environmental media. Estimation is carried at an environmental temperature of 25 °C.
Applicant's summary and conclusion
- Conclusions:
- The distribution of dibenzyl ether into all environmental media was calculated according to the Mackay fugacity model level I based on the physico-chemical properties. The main target compartment for dibenzyl ether is water with 54.4 %, followed by air with 27.8 %, sediment with 8.9 % and soil with 8.8 %.
- Executive summary:
The distribution of dibenzyl ether into all environmental media was calculated according to the Mackay fugacity model level I based on the physico-chemical properties. The main target compartment for dibenzyl ether is water with 54.4 %, followed by air with 27.8 %, sediment with 8.9 % and soil with 8.8 %.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
