Estimation Method for the Volatilization of Pesticides from Fallow Soil

摘要

Many pesticides partly volatilize from the soil surface after applications. Theseemissions need to be quantified in order to estimate net loads on the soil and subsequent leaching to surface and groundwater. A general method was lacking to estimate the cumulative volatilization as a function of the pesticide's properties and the most relevant environmental parameters. By correlating volatization data from the literature to the fraction of the pesticide in the gas phase of the topsoil, a number of easy-to-use regression equations were derived for greenhouse and field conditions.
