Highly host-linked viromes in the built environment possess habitat-dependent diversity and functions for potential virus-host coevolution

Autor: Shicong Du, Xinzhao Tong, Alvin C. K. Lai, Chak K. Chan, Christopher E. Mason, Patrick K. H. Lee

Publikováno v: Nature Communications, Vol 14, Iss 1, Pp 1-15 (2023)

Abstract Viruses in built environments (BEs) raise public health concerns, yet they are generally less studied than bacteria. To better understand viral dynamics in BEs, this study assesses viromes from 11 habitats across four types of BEs with low t

Evaluation of Single-Pass Disinfection Performance of Far-UVC Light on Airborne Microorganisms in Duct Flows

Autor: Huihui Zhang, Alvin C. K. Lai

Publikováno v: Environmental Science & Technology. 56:17849-17857

Far-UVC irradiation (222 nm) is considered an emerging and sustainable solution for future infection and pandemic challenges. We examined the disinfection performance of a krypton-chloride lamp, with a quasi-monochromatic UVC peak at 222 nm, for inac

Study of synergistic disinfection by UVC and positive/negative air ions for aerosolized Escherichia coli, Salmonella typhimurium, and Staphylococcus epidermidis in ventilation duct flow

Autor: Sunday S, Nunayon, Hui H, Zhang, Vincent, Chan, Richard Y C, Kong, Alvin C K, Lai

Publikováno v: Indoor airREFERENCES. 32(1)

The efficacy of the in-duct application of ultraviolet waveband C (UVC) emitting at 254 nm wavelength and air ions against aerosolized bacteria was studied in a full-scale 9-m long ventilation duct. Combined positive and negative ion polarities (bipo

Indoor Particulate Matter of Outdoor Origin: Importance of Size-Dependent Removal Mechanisms

Autor: William J. Riley, and Alvin C. K. Lai, Thomas E. McKone, William W. Nazaroff

Publikováno v: Environmental Science & Technology. 36:1868-1868

Adverse human health effects have been observed to correlate with levels of outdoor particulate matter (PM), even though most human exposure to PM of outdoor origin occurs indoors. In this study, we apply a model and empirical data to explore the ind
