Rapid analytical methodology has been developed for multi-residue
determination of pesticides in soils using liquid chromatography coupled to tandem
mass spectrometry (LC-MS/MS) with triple quadrupole analyzer. Soil samples were
collected from Argentina in 12 representative agricultural areas, and 18 pesticides were
selected on the basis of their use. Special attention was paid to minimize sample
preparation, making easier the method application to routine analysis. Several
extraction procedures were tested, performing a careful study on matrix effects. The
method finally proposed (extraction with acetonitrile and subsequent 2-fold dilution with
water without any clean-up step) was fully validated at 0.05 and 0.5 mg/kg on the basis
on European SANCO 12571/2013 and 825/00 guidelines. The method applicability and
robustness was demonstrated by analysis of quality control (QC) samples, consisting
on eleven soils spiked at 0.5 mg/kg. These soil samples were collected from different
experimental plots, and were very diverse in their physico-chemical characteristics. The
methodology developed is of easy application, there is low consumption of solvents
and reagents, and no clean-up is required despite the complexity of the soil matrix. In
the near future, the method developed will be used to monitor the presence of
pesticides in large agricultural areas of Argentina. [-]
