Resumo
A simple multiresidue direct solid phase microextraction (SPME) method with PA fiber is described for determination of pesticides in water samples. The residues were determined by gas chromatography with mass spectrometry detection (GC/MS). The recovery obtained for the proposed method ranged from 94% to 110% and the sensitivity of the method was determined by calculating the limit of detection (DL) that ranged from 0.004 to 0.1 μgL-1. The results obtained with spiked real sample, at three concentration levels, showed acceptable agreement with the expected values.
