Extent of interactions between pesticides and soils varies on a large scale. As a result of adsorption processes it is of high interest to model bioavailability of widely used pesticides, as well as to compare this feature to obtain adequate data on prospective toxicological problems. Our work signifies major innovations in terms of applying different extraction model systems and involving pesticides have not been studied so far for bioavailability. Our major goal was to make a comprehensive comparison between different experimental methods to model bioavailability of pesticides and to find the most efficient one. The applied 5 extraction models showed diverse efficiency in extracting capability of pesticides. The five pesticides examined were simazine, carbendazim, acetochlor, chlorpyrifos and diuron. For the examination sandy, brown forest and alluvial soils were applied. The extracted amounts were determined by GC/MS and HPLC/MS techniques. Our studies involved comparative studies of sterilized and real soil samples to estimate the extent of the microbiological degradation processes in case of three pesticides: simazine, diuron and acetochlor. 3 extraction models proved to be suitable for assessment of the available amount of pesticides for living organisms. As a result both the adsorption capabilities of soils and biological accessibility of pesticides could be estimated in accordance with the microbiological characteristics of soils.
