“…These results point to the fact that the nonthermal plasma source was a source of reactive oxygen species (ROS) and excited nitrogen species (RNS). The gas phase chemistry of nonthermal discharges in air is complex and may involve as many as 500 reactions and 75 species [30][31][32]. Furthermore, complexity is also added by the wide ranges of length and time scales of such plasmas [33].…”

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.

Combined experimental and modeling studies of acetylene oxidation in pulsed corona discharges working in the nanosecond regime are presented. The corona cell was characterized in term of power deposition to provide input data for the model. The concentrations of ozone, CO, CO 2 and residual acetylene were systematically measured for model validation purposes. The model used allows describing the detailed chemistry in the discharge and the mass transfer between the microdischarges and the discharge free regions in the corona cell. Results showed that the model allows a satisfactory prediction of the acetylene residual fraction, CO and CO 2 yields and O 3 concentration for a wide range of conditions. They enabled a precise identification of the product distribution and confirmed the central role of O-atom in the oxidation process. They also revealed that ketene, H 2 CCO, plays an important role in the oxidation mechanism and allowed drawing some conclusions on the optimization of the oxidation process.
