abstract = "Nonequilibrium atmospheric pressure plasma proved to produce reactive chemistry environment at gas temperatures as low as room temperature which is perfect for treatments of different kind of surfaces. Over the past several years cold atmospheric pressure plasma applications in surface sterilization and cleaning have been extensively studied. Recently, the research has been directed to utilization of this type of plasma far agriculture. Plasma is used directly for treatment of seeds, but, also, indirectly through plasma activated water. In the case of decontamination of water contaminated with conventional pesticides and insecticides plasma can play important role. One of suitable plasma sources for these treatments are atmospheric pressure plasma jets (APPJ), since they are small-size (easily scalable to larger systems), relatively technically simple and cost-effective devices. In our case, we investigated treatments of water contaminated with three types of pesticides. Decontamination is achieved by applying the jet on the liquid surface generating high-energy electrons, reactive oxygen and nitrogen species, radicals and ultraviolet radiation. Reactive species created al the gas-liquid interface effectively degrade organic pollutants in the water. However, due to the complexity of the system, key mechanisms important for destruction of particular contaminant are not clearly known. Moreover, optimisation of the system is recondite by reciprocal influence of the jet and surface. Thus, we have performed detailed and systematic investigation of the APPJ-liquid sample system properties at different conditions and far different pollutants dissolved in water. Electrical and optical measurements provided information about the discharge running at different powers and distances from the sample. We could relate electrical characteristics with spatial profiles of the discharge. Moreover, optical spectrometry provided data on emission lines characteristic far the plasma used far decontamination. By using liquid chromatography measurements of contaminated water samples before and after the treatment we acquired evidence on destruction of specific pollutants and found decontamination rates. AII this data is valuable far evaluation of APPJ efficiency at different operating conditions and optimisation of the decontamination process.",
