A method for the extraction and subsequent quantitative determination of dialkyl phthalates (DAPs) in soil using gas chromatography combined with tandem mass spectrometry is suggested. The method is characterized by low limits of detection, as well as high sensitivity and selectivity. The optimal conditions for DAP extraction from soils were selected and evaluation of the possible secondary contamination of DAP samples from labware and chemicals and distribution of DAP in soil were performed.
