Application of solid phase microextraction (SPMŁi) and gas chromatography combined with mass spectrometry (GC-MS) for analysis of the chlorophenoxy herbicide residues was studied. The optimal conditions for SPME/GC-MS analysis of chlorophenoxy herbicides were determined as follows: adsorption time 15-20 min at 50°C and desorption time 6 min at 220°C. The highest concentration of MCPA was found in the tissues of the weeds of M. inodora, C. bursa pastoris, while the lowest in A. githago, P. aviculare. In addition to that, in May and June the studied herbicides were found in low quantities in the surface waters of the river of Liwiec.

Podjęto próbę połączenia mikroekstrakcji z chromatografią gazową i spektrometrią masową (SPME/GC-MS) podczas analiz pozostałości herbicydów chlorofenoksyoctowycli. Określono optymal­ne warunki adsorpcji ( 15-20 min, 50°C) i desorpcji (6 min, 220°C) mikroekstrakcji badanych herbicy­dów. W tkankach chwastów M. inodora, C. bursa pastoris, A. githago i P. aviailare oraz pszenicy ozimej odmiany Roma wykryto badane herbicydy. Herbicydy chlorofenoksyoctowe występowały także w wo­dach powierzchniowych w maju i czerwcu, na ogól po 3 dniach od wykonania zabiegów.
