Development and validation of a rapid multiresidue method for pesticide determination using gas chromatography-mass spectrometry: a realistic case in vineyard soils.
A rapid and simultaneous method for residue identification and quantification for seven pesticides in agricultural soils has been developed to study a realistic situation in vineyard. The target compounds are two insecticides, two herbicides and three fungicides, from different chemical families. The procedure is based on a pressurized liquid extraction (PLE) with acetone, before a multiresidue GC-MS analysis. The recovery of PLE is between 53.8+/-2.4 and 99.9+/-4.4% according to pesticide. A limit of detection (LOD) between 1.4 and 4.6 microg kg(-1) of dry soil was obtained for five analytes. This procedure for testing soil contamination is sensitive and easy to perform.
