The objective of this work was to create a sorption model of different pesticides in plant material. The above-quoted model includes graphic curves describing the pesticide’s behaviour in time (concentration level) depending on the place of sorption. Apart from curves the model also includes mathematical equations that allow us to predict the concentration of a pesticide in time function. The model has been developed based on research data obtained in a special experimental device. This article accounts for the transportation model of chosen xenobiotics in plants. Chlorothalonil were used as a model pesticide. Chlorothalonil is a nonsystemic fungicide that has been used to control disease of many fruits, vegetables, and other agricultural crops. As a method of sample preparation supercritical fluid extraction was used. Gas chromatography with mass spectrometry was used for qualitative and quantitative analysis. The detection limit (LOD) of chlorothalonil was on level 0.01 µg/g. and the limit of quantification (LOQ) was level on 0.03 µg/g.
