Results and discussion
Any other information on results incl. tables
Air, soil, water and sediment concentrations were estimated.
Level I Level II Level III(default*)
(air/water/soil)
Air 95.4% 95.4% 0.54%
Water 0.18% 0.18% 31.2%
Soil 4.3% 4.3% 61.7%
Sediment 0.10% 0.10% 6.6%
Level III (default*) Level III (air only) (water only)
Air 99.6% 3.0% Water 0.02% 80.0% Soil 0.37% 0.01%
Sediment 0.00% 16.9%
Remarks: Since default assumptions for release estimates were used, resulting environmental concentrations are not provided.
Air % (Fugacity Model Level I): 95.4
Water % (Fugacity Model Level I): 0.18
Soil % (Fugacity Model Level I): 4.3
Applicant's summary and conclusion
- Conclusions:
- These results indicated that 1,3 diethylbenzene will partition primarily to air under equilibrium conditions (Level I and II models), but to soil and water under the assumed pattern of chemical release (equal loading of water, soil and air) in the Level III model. These results reflect the Level III model's loading pattern plus the estimated moderately long half-life in water and soil and short half-life in air.
