Sunlight is a known biocide, and photodriven inactivation an important avenue for controlling viruses in both natural engineered systems. However, there remain significant unknowns regarding damage to by sunlight, including the impact of wavelength viral characteristics. Herein, systematic review literature meta-analysis was conducted identify rate constants (k-values) when exposed solar wavelengths (280-700 nm) common human surrogates synthetic matrices. We identified 457 k-values, with 356 nonenveloped viruses. Extracted were transformed into UV fluence-normalized k-values isolate most photobiologically relevant spectrum reported first time terms energy, rather than time, based units. Each spectral region assessed independently, UVB illumination reporting highest rates, UVA contributing presence absence photosensitizers, visible light demonstrating no biocidal activity. Inactivation mechanisms are reviewed identifying knowledge gaps translating UVC longer wavelengths. The data compiled this can be applied inform environmental transport viruses, estimate disinfection performance variable conditions, or design systems on light.

UV exposure is a common method of disinfection and sterilization. In the present study, parallel beam test was performed to collect fluids containing infectious viruses using apparatus after UV254 irradiation (0, 0.5, 1, 3, 5, 7, 10, or 20 mJ/cm2). The air sterilization by irradiating in ducts with light 2, 4, 6 mJ/cm2) airborne particles through equipment. Furthermore, viral inactivation assessed based on cytopathic effect (CPE) detection immunofluorescent assays (IFA). Both CPE immunofluorescence signal intensity decreased as dose increased. doses required inactivate ASFV (107.75 copies/mL), PRRSV (106.29 PEDV (107.71 copies/mL) water were 1 mJ/cm2, respectively. (104.06 (103.06 (104.68 mJ/cm2. This study provides data for biosecurity prevention control swine farms.
