| Abstract/Contents: | "Microwave-assisted solvent extraction (MASE) was investigated as an alternative for extraction of parathion (O,O-diethyl O-4 nitrophenyl phosphorothioate), methylparathion (0,O-dimethyl O-4-nitrophenyl phosphorothioate), p,p'-dichloro-2,2-bias(4-chlorophenyl)ethane], hexachlorobenzene (HCB) , simazine (6-chloro-N2, N4-diethyl-1,3,5-triazine-2,4-diamine) and paraquat dichoride (1,1'-dimethyl-4,4'-bipyridinium) from two different soils and from an earthworm-growing substrate. The matrices were fortified with 14C-radiolabeled pesticides and extracted with various solvent systems under different microwave conditions. Recoveries of more than 80% could be obtained depending on the used microwave conditions and solvent, except for paraquat whose recovery was generally less efficient. Thus, MASE can be successfully used to extract pesticides from environmental and biological samples and could be a viable alternative to conventional extraction methods. The technique uses smaller amounts of organic solvents, thereby minimizing the costs of the analysis and the disposal of waste solvent." |
