Reprint of bioaerosol: A bridge and opportunity for many scientific research fields

Abstract

Bioaerosol collectively refers to all suspended particles of biological origins in the air. In theory, all biological materials can be released either directly or resuspension into the air upon various disturbances from the earth surfaces such as soils, oceans, animals, forests, humans and etc. Once airborne, as shown in Fig. 1 biaoerosol particles could undergo human inhalation, dry/wet depositions, aerial transport, ice nucleation, cloud condensation processes, atmospheric transformation and others. Accordingly, they have important impacts on infectious disease spread, allergic diseases, bio-security, atmospheric chemistry as well as climate (Douwes et al.,

Bioaerosol Sources, Sampling Methods, and Major Categories: A Comprehensive Overview

“…The presence of bioaerosols has been suspected to significantly impact human health as a biological pollutant (Douwes et al, 2003;Kim et al, 2018;Yao, 2018). Bioaerosols are not self-contained pollutants, but a mixture of various compounds, for example, bacteria, fungi, viruses, and pollen (Jiayu et al, 2019).…”

Bioaerosol field measurements: Challenges and perspectives in outdoor studies

“…Instead, we focus on a high-level discussion of pressing scientific questions, grand challenges, sampling recommendations, and needs for cross-disciplinary collaboration. Comprehensive reviews can be found elsewhere (Yao 2018;Buters et al 2018;Delort and Amato 2017;N uñez et al 2016a, 2016b; Fr€ ohlich-Nowoisky et al 2016; Sofiev and Bergmann 2013;Despr es et al 2012;Xu et al 2011;Morris et al 2011;Womack, Bohannan, and Green 2010;Georgakopoulos et al 2009;Jones and Harrison 2004;Madelin 1994). Contributions were compiled from a group of authors with diverse sets of backgrounds and expertise, with more emphasis added from the perspective of the atmospheric sciences than others, e.g., health sciences.…”

Aerosol filtering efficiency of respiratory face masks used during the COVID-19 pandemic

“…Aerosol (or airborne particulate matter, PM) is defined by the International Union of Pure and Applied Chemistry, IUPAC as: “ Mixtures of small particles (solid, liquid, or a mixed variety) and the carrier gas (usually air); owing to their size, these particles (usually less than 100 μ m and greater than 0.01 μ m in diameter) have a comparatively small settling velocity and hence exhibit some degree of stability in the earth’s gravitational field” (Calvert, 1990). Viruses are a category of aerosol of biological origin and referred to as bioaerosol (Douwes et al , 2008; Yao, 2018). Viruses, such as SARS, H1N1 and MERS-CoV, pose distinct health risks, in addition to the known aerosol health effects (Yao, 2018).…”

“…Viruses are a category of aerosol of biological origin and referred to as bioaerosol (Douwes et al , 2008; Yao, 2018). Viruses, such as SARS, H1N1 and MERS-CoV, pose distinct health risks, in addition to the known aerosol health effects (Yao, 2018). Their transmission from person to person through the atmosphere is a pathway of infection that is not well explored, although a very important one, especially for the indoor environments (Nazaroff, 2016; Yao, 2018; Anderson et al , 2020; Fears et al , 2020).…”
