The application of SPME/GC-MS in order to determine the (4-chloro-2-methylphenoxy) acetic acid (MCPA) residues in winter wheat seedlings tissues has been studied. The optimal conditions for the SPME of MCPA adsorption were 20 min. in 50oC and 6 min. in 220oC for desorption. The chlorophenoxy herbicide showed different level of accumulation in seedling tissues of studied winter wheat cultivars. The application of the SPME/GC-MS method for the MCPA residues monitoring and possible differences in its biodegradation in the studied wheat tissues is discussed.

Zbadano możliwość zastosowania metody SPME/GC-MS do analiz pozostałości kwasu 4-chloro-2-metylofenoksyoctowego (MCPA) w tkankach siewek pszenic ozimych. Stwierdzono, że w przypadku adsorpcji optymalne warunki dla mikroekstrakcji SPME estru metylowego MCPA to temperatura 50oC i czas trwania procesu 20 min, a dla desorpcji odpowiednio 220oC i 6 min. W tkankach siewek pszenic ozimych stwierdzono zróżnicowaną zawartość pozostałości MCPA. Prawdopodobnie mechanizmy biodegradacji tego herbicydu są zróżnicowane.
