The basic principles and application possibilities of the methods based on solid phase microextraction (SPME) in the analysis of pesticide residues in soil samples are presented in the paper. The most important experimental parameters which affect SPME efficacy in pesticide determination (type and thickness of microextraction fiber, duration of microextraction, temperature at which it is conducted, effect of addition of salts (the effect of efflorescence), temperature and time of desorption, the choice of optimal solvent for pesticide exctraction from the soil and the optimal number of extraction steps), as well as general guidelines for their optimization are also shown. In the end, current applications of SPME methods in the analysis of pesticide residues in soil samples are presented.
