Materials and methods

Model:
calculation according to Mackay, Level III
Calculation programme:
Level III fugacity model contained in EPI Suite (v.4.00-4.10, ©2000-2008). The model is a direct adaptation of the method that was developed by Dr. Mackay.

Results and discussion

Percent distribution in media

Air (%):
17.2
Water (%):
80.6
Soil (%):
0.75
Sediment (%):
1.2
Other distribution results:
(weighted mean distribution)
Using actual release rates, persistence times in the environment ranging from 80.9 to 273 hours (3.4 – 11.4 days) are calculated.

Applicant's summary and conclusion

Conclusions:
The constituents of Oxooil LS9 will predominantly partition to the water compartment or will show volatilisation into air. Soil and Sediment are expected to be minor compartments for distribution. Using actual release rates, persistence times ranging from 80.9 to 273 hours (3.4 – 11.4 days) are calculated.
