“…Assuming a waler solubility of 15 ;/g g ' and a vapour pressure of 7 x 10 "' mm of mercury (Yih et al, 1970), the water/air distribution ratio, KJ^, can be estimated to be about 17000. The pesticide capacity factors of the soils with respect to concentrations in the gas and water phases can then be calculated (Leistra, 1972(Leistra, , 1973. The average rate of the convective transport of ihe herbicide in a time interval (Table 5) is obtained by dividing the water flux by the capacity factor with respect to the concentration in the water phase.…”

Evaporation is the phase transition process that plays a significant role in many spheres of life and science. Volatilization of hazardous materials, pesticides, petroleum spills, etc., impacts the environment and biosphere. Predicting evaporation fluxes under specific environmental conditions is challenging from theoretical and empirical points of view. A new practical method for estimating fluxes is proposed based on our experimental results and previously published data. It is demonstrated that some parameters in theoretical equations for near-equilibrium evaporation can be estimated from experiments, and these formulas can be exploited to predict steady-state evaporation fluxes in the air in a range of 8 orders of magnitude based on a single experiment carried out for nontoxic volatile compounds.
