“…Although the EI mode was used for the general method, a supplementary methodology based on GC-(NCI) MS using the selected ion recording (SIR) mode was proposed for quantification and confirmation of OC pesticides as it allowed notable sensitivity improvement for these compounds. As regards confirmation identity, it is based on the presence of at least two SRM transitions 25,71,72,76,77,79 and R t agreement, although several authors also took into account the experimental relative intensity ratio of the sample and the theoretical ratio of the reference standard, using the maximum deviations established in the European The GC-MS/MS methods applied in the analysis of environmental samples presented excellent sensitivity. In the case of soils and sediments, the lowest level validated was as low as 1 ng g −176 or 5 ng g −1 .…”

“…The outer layer Nafion enhances the durability and stability of the coating, being robust enough for replicated extraction for at least 150 times. Authors reported the direct GC analysis of carbamates without derivatization, in analogy to other studies [145,146]. Nanohybrids of CNTs/metal oxides have been applied to the determination of pollutants in vegetables.…”

“…The current methods used in the detection of carbamate pesticides include high‐performance liquid chromatography , gas chromatography , fluorimetry , immunosensors and flow‐injection chemiluminescence . These techniques are often time consuming and boring with need expensive tools and expert operators that restrict them to routine operations.…”
