Abstract
Pesticide destiny in soil depends on a number of factors, as well as on
presence and intensity of the processes such as adsorption, degradation,
evaporation, rinsing and leaching. Since adsorption processes govern
concentration of the free fraction of pesticide molecules, researches in this
area are primarily focused on examination of this process, more precisely on
determination of adsorption constants and adsorption/desorption isotherms
which provide determination of the most responsible soil properties for the
retention of the tested pesticides in the soil. Since rinsing across the soil
profile is the most frequent and its intensity is indirectly determined by
intensity of adsorption processes, determination of adsorption constants of
pesticides provides determination of rinsing potential for these substances
across the soil profile. Methods for determination of pesticides adsorption
properties and examination of their mobility in soil, primarily across the
soil profile, are presented in the paper. Special emphasis is placed on the
?batch? method, which is currently the most common, and which was actually
proposed by the Organization for Economic Cooperation and Development (OECD).
