“…Gas chromatography coupled to mass spectrometry (GC-MS/MS) is widely used in the analysis of pesticides that are highly volatile [25]. We employed an Agilent 7890N GC coupled with Agilent 7000A triple quadrupole MS for the analysis of pesticides, with ionization achieved by electron impact at 70 eV in multiple reaction monitoring (MRM) mode.…”

Keywords: nonthermal plasma, dielectric barrier discharge, pesticide, GC-MS/MS AbstractIn-package nonthermal plasma (NTP) technology is a novel technology for the decontamination of foods and biological materials. This study presents the first report on the potential of the technology for the degradation of pesticide residues. A cocktail of pesticides, namely Azoxystrobin, Cyprodinil, Fludioxonil and Pyriproxyfen was tested on strawberries. The concentrations of these pesticides were monitored in priori and post-plasma treatment using GC-MS/MS. An applied voltage and time dependent degradation of the pesticides was observed for treatment voltages of 60, 70 and 80 kV and treatment durations ranging from 1 to 5 min, followed by 24 h in-pack storage. The electrical characterisation revealed the operation of the discharge in a stable filamentary regime. The discharge was found to generate reactive oxygen and excited nitrogen species as observed by optical emission spectroscopy.

“…A variety of methods have been developed to determine these pesticides in water. In general, gas chromatography (GC) [4][5][6][7][8][9] and high-performance liquid chromatography (HPLC) [10][11][12][13][14][15][16] are the most used analytical techniques. However, but an enrichment procedure is often needed because of the complex matrices for the pesticide analysis at trace level in the water system.…”

a b s t r a c tA high voltage dielectric barrier discharge plasma reactor using atmospheric air as the inducer gas was studied for the degradation of pesticides (dichlorvos, malathion, endosulfan) in water. The degradation kinetics of the pesticides were studied using GC-MS as a function of plasma control parameters. Electrical characterisation of the plasma revealed that the plasma discharge consisted of filamentary streamers. Excited nitrogen, reactive oxygen species and OH radicals generated in the dielectric barrier discharge (DBD) plasma reactor were identified using optical emission spectroscopy. Ozone, used as an indicator for metastable oxygen species, was quantified within the reactor at concentrations of 1600, 2200, 2800 ppm after 8 min of plasma treatment for applied voltages of 60, 70, and 80 kV respectively. The degradation efficacy of pesticides after 80 kV and 8 min of plasma treatment were found to be 78.98 ± 0.81% for dichlorvos, 69.62 ± 0.14% for malathion and 57.71 ± 0.58% for endosulfan. Degradation was found to follow first order kinetics. GC-MS analyses showed that the degraded compounds and intermediates formed were less toxic than the parent pesticide. A proposed mechanism of degradation of these pesticides is suggested.
