Other Distribution Data

KOAWIN v1.10

AEROWINv1.00

Volatilization from Water

Log Koa (octanol/air): 17.781

Koa (octanol/air): 6.035E+017

Sorption to aerosols at25°C: Kp (particle/gas partition coef.) 5.91E+003 m3/ug (Mackay model); 1.48E+005 m3/ug (Octanol/air model); Fraction sorbed to airborne particulates (phi): 1 (Junge-Pankow, Mackay, and Octanol/air models)

Half life: 6.1x10+8 years (River); 6.6x10+9 years (Lake)

Applicant's summary and conclusion

Conclusions:
The Koa indicates a preference to air over solvents. Sorption to aerosols and particulates is predicted, whereas volatilization from rivers and lakes is not.
