Conclusion : According to EPIWIN, assuming equal emissions to air, water, and soil, this<br />
chemical will concentrate mostly in water (46.1 %) and soil (53.7 %).<br />
This chemical will take about 21.61 years to volatilize from a model river,<br />
and 235.8 years to volatilize from a model lake.<br />
