Abstract
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 μg kg−1 of dry soil was obtained for five analytes. This procedure for testing soil contamination is sensitive and easy to perform.
