A model to assess the rate of evaporation of chemical compounds from surface waters

A model has been developed to assess the rate of evaporation of chemical compounds from surface waters. It is based on the two-boundary-layer model of Lewis and Whitman, on critically evaluated literature data and on specific experiments. The rate of evaporation is assessed as a function of the diffusion coefficient in air and water and of Henry's coefficient in water, being the physico-chemical parameters, and as a function of the wind speed, the water temperature and the water depth, being the environmental parameters.
