Plotting and analysis of the surviving populations of nebulized E. coli O157:H7 (a), S. Typhimurium (b), L. monocytogenes (c), and S. aureus (d) after UVC LED array irradiation using the Weibull model equation. The experimental procedure included 5 min of nebulization, UVC treatment, and 5 min of air sampling with an AGI-30 glass impinger. The error bars indicate SDs.
