Description
Summary:The process of chlorothalonil uptake in selected plant materials was studied. Each part of the plant was homogenized, mixed with anhydrous magnesium sulphate and was extracted by a supercritical fluid extractor (SFE). After extraction chromatographic analysis was carried out in a gas chromatographer equipped with a mass spectrometer (GC-MS). The longer the time period between the saturation process and the analysis phase, the lower the chlorothalonil concentration in a plant part analyzed. For radish and lettuce highest concentration occurred after half an hour of the saturation process. Poor transport in a plant was caused by low solubility of chlorothalonil in water, the structure of the plant and by the chemical and physical properties of a compound. Better correlations were shown between time and concentration of pesticide for lettuce than radish.
