“…However, one of the limitations of this method is the poor penetration ability of PL resulting in a lower reduction in counts of microorganisms present on irregular surfaces (Huang & Chen, ). There are no individual pesticide degradation studies done on produces using PL, however, the use of PL (325 μs, 0.7 J/cm 2 fluence) for the degradation of pesticide mix (chlorpyriphos ethyl, phosmet, azinphos‐ethyl, pirimiphos‐methyl, and atrazine) in water resulted in more than 50% reduction in their concentration in milliseconds (Baranda, Fundazuri, & de Maranon, ). Decontamination of fresh produce using PL is a promising technology; however, a detailed study is required to investigate the penetration of light, the effect of the shape and topography of produce, and stability of pesticides under these conditions.…”

Fresh fruits and vegetables are a rich source of micronutrients. However, many foodborne illnesses have been linked to the consumption of fresh fruits and vegetables as they are reported to harbor contaminants such as microorganisms and pesticides. Recently reported foodborne outbreaks have been linked to a diverse group of fruits and vegetables due to the presence of various pathogens including Salmonella, Escherichia coli, and Listeria monocytogenes. Also, the increased use of pesticides has resulted in the deposition of chemical residues on the surface of fruits and vegetables, which has led to the adverse health conditions such as cancer, birth defects, and neurodevelopmental disorders. Fresh commodities are subjected to various treatments to prevent or minimize these outbreaks, and the main targets of such treatments have been the elimination of pathogens and degradation of toxic chemical residues. Here, we have discussed various decontamination methods including simple household washing, chemical treatments, and modern technologies with their mode of action for microbial and pesticide removal. The simple household processes are not very effective in the removal of pathogenic organisms and pesticides. The use of modern techniques like cold plasma, ozone, high hydrostatic pressure, and so on, showed better efficacy in the removal of microorganisms and pesticides. However, their industrial use is limited considering high installation and maintenance cost. In this review, we suggest combined methods based on their mode of decontamination and suitability for a selected fruit or vegetable for effective decontamination of microbes and pesticide together to reduce the treatment cost and enhance food safety.

“…However, in the current stage of the society, the use of treatment methods that enable the reduction of pollution is also extremely appropriate. In this sense, the advanced oxidation process based on the use of semiconductor materials has demonstrated high efficiency in air purification [2][3][4] or liquid effluents [5,6].…”

The photocatalytic asphalt mixture provides safer roads and mitigates the air quality problems, trapping and degrading organic compounds and also harmful gases. In this research, an asphalt mixture was functionalized with nano-TiO 2 by bulk incorporation, using the contents 3 and 6%, and by spraying coating using an aqueous solution over its surface at different temperatures and rates. For bulk incorporation, the mechanical performance was assessed. The factorsapplication procedure, influence of temperature, spraying rate, incorporation percentage and TiO 2 immobilization (from traffic and rain removal)were evaluated based on Rhodamine B (RhB) degradation. For bulk incorporation, the best content nano-TiO 2 was 3%. The temperature of the substrate has no influence on the photocatalytic results. The most effective spraying rates were 8 and 16 mL/cm 2 . Before simulating the traffic effect, the spraying coating technique was more effective than the bulk incorporation one. After this process, the opposite behaviour was detected. The rain simulation did not cause removal of the nanoparticles. Additionally, the exposed aggregates affected the photocatalytic efficiency, being important their contribution combined to the effect of nano-TiO 2 . To have the maximum benefit of the techniques studied, the ideal solution would be the combination of both, with negligible impact on mechanical performance. NO O NO 2 3(3)O 2 and OH − species required in the above equations are abundantly available in the atmosphere. Consequently, the immobilization of photocatalysts over different external surfaces of the built environment, such as pavements, roofs, tiles, glass, among others, which are subjected to weather (humidity, rain and sunlight), represent a good strategy to sustainably mitigate air pollution.

“…Photolysis mainly includes ultraviolet (UV) light irradiation ( 27 , 30 – 34 ), pulsed light (PL) technology ( 4 , 35 , 36 ), as well as visible light illumination ( 37 , 38 ). The UV spectrum falls into UV-A (380–315 nm), UV-B (315–280 nm), UV-C (280–200 nm), vacuum-UV (VUV) (200–100 nm), and extreme UV (100–1 nm).…”

“…As known, PL technology contains a successive repetition of short duration (325 μs) and high power flashes emitted by xenon lamps that range from ∼200 to 1,000 nm with a considerable amount of light in the short-wave UV spectrum. Baranda et al investigated the photodegradation of several triazidic and organophosphorus pesticides in aqueous solutions by PL technology ( 35 ). The most studied pesticide residues were degraded very fastly, and their degradation was greater than 50% in a short period of time (milliseconds).…”

Pesticide residues are of great significant issue that exerted adverse effects on humans. There is a need for effective and non-toxic decontamination of pesticide residues during food processing. In this minireview, the recent advances in the degradation of pesticide residues by photolysis have been firstly described during food processing. The mechanisms of pesticide residues destruction by photolysis were discussed accordingly. Finally, applications of photolysis in the degradation of pesticide residues from beverages, fresh produce, and food rinse waste were also summarized.
