heal.abstract	Several simple models for the estimation of the half-life (t(1/2)) for the depiction of an organic chemical from a soil surface to air were examined. For moist surfaces, two models are proposed: the first requires knowledge of the soil/ organic carbon partition coefficient (K-proportional to) and the Henry's law constant (H) and the second the vapor pressure (P-s) of the chemical involved. Due to uncertainties in the experimental K-proportional to values those ones predicted by the group-contribution model of Meylan et al. [Environ. Sci. Technol. 26 (1992) 1560]-and proposed by the U.S. Environmental Protection Agency (EPA)-should be used. If reliable experimental P-s values are not available. the first model is proposed, where in cases when H values are not available. predicted ones by the Bond-Contribution method of Meylan and Howard (Environ. Toxicol. Chem. 10 (1991) 1283)-and also proposed by EPA-can be used. In general. the agreement of the predicted t(1/2) values with the measured ones is within a factor of 3-5. Similar expressions but with somewhat poorer results are presented for dry field soils. In all cases. the obtained results represent a substantial improvement over those obtained with the currently used Dow method: t(1/2) = 1.58 - 10(-8)(Kproportional to(.)S/p(s)), where S is the solubility of the compound in water.
