Atmospheric cold plasma dissipation efficiency of agrochemicals on blueberries

Influence of low‐pressure nonthermal dielectric barrier discharge plasma on chlorpyrifos reduction in tomatoes

“…Nevertheless, in all the plasma‐treated tomatoes, the lightness value decreased considerably as given in Table that is, the fruits are lesser bright after the treatment. Similar results were observed by (Sarangapani et al, ). The disruption of the epicuticular wax layer by the bombardment of ions and radicals on the fruit epicarp could be attributed to the reduced lightness.…”

“…The existing studies on pesticide degradation in water and soil surfaces using nonthermal plasma exhibits the potentiality of the technique (Kim, Kim, & Kang, ) (Bai, Chen, Yang, Guo, & Zhang, ) (Reddy, Mahammadunnisa, & Subrahmanyam, ) (Sarangapani et al, ). However, exploration of the technique for remarkable pesticide reduction in agricultural commodities (Dorraki, Mahdavi, Ghomi, & Ghasempour, ; Phan et al, ; Sarangapani, O'Toole, Cullen, & Bourke, ) with the consideration of their physicochemical changes was limited. Hence, the main objective of the current work is to investigate the effect of cold plasma on chlorpyrifos reduction in tomato and its physicochemical properties.…”

“…According to Sarangapani et al (2017) cold plasma is reported to be a potential biological decontamination method to avoid microbiological and chemical risks related to food commodities including fruits and vegetables. The effect of cold plasma exposure in order to degrade pesticides, including imidacloprid and boscalid on blueberries subsequently to sustain important quality criteria of them during post exposure was investigated by a high-voltage dielectric barrier discharge plasma reactor.…”

“…No significant change in physical properties like color was observed, but some acceptable changes were recorded in the firmness of the fruits. The quality retention of blueberries was provided by using cold plasma (Sarangapani et al, 2017). Another study was carried out on apple and spinach samples exposed to omethoate by generating low-temperature plasma through a dielectric barrier corona discharge and it was found that, after twenty minutes of treatment, the number of omethoate remnants in apple and spinach was (94.55 +/-0.01)% and (95.55 +/-0.01)%, respectively.…”

Humic acid and trihalomethane breakdown with potential by-product formations for atmospheric air plasma water treatment

“…The use of atmospheric air as the inducer gas facilitates a potentially environmentally friendly and economically feasible approach. Atmospheric air plasma has been reported to be efficient in the breakdown of dyes [24], pesticides [25,26], aflatoxins [27] and for inactivation of pathogenic bacteria [28]. It is known that dielectric barrier discharge (DBD) plasma initiates several physical processes (UV light, shock waves) and chemical processes (O , O 3 , H 2 O 2 ) [29], processes which may directly or indirectly act on humic substances.…”
