Aerosolized SARS-CoV-2 exposure assessment: dispersion modeling with AERMOD

Modeling the air pollutant concentration near a cement plant co-processing wastes

“… 31 The concentrations of the PTEs in the north-eastern and south-western direction are lower than the background value, which can be attributed to the fact that the wind from the north-eastern and south-western directions is not strong and there are many high buildings in these two directions, blocking the dispersion of the pollutants. Moreover, the wind velocity can also affect the dispersion of the pollutants, which was proven by a previous study, 43 which showed that the peak concentration of pollutants can move further away from the source with an increase in wind speed. Besides, the peak concentration shape followed a Gaussian distribution in a high speed wind case compared to that in the low speed wind case, which is also in accordance with our study.…”

Dynamics of SARS-CoV-2 spreading under the influence of environmental factors and strategies to tackle the pandemic: A systematic review

“…used CFD to study the optimum seat in the first business and economy section of the commercial plane, considering the temperature, air velocity, and CO 2 mass fraction, which would help the public to decide which seat to occupy for their next flight during COVID-19 traveling. Moreover, air dispersion models such as AERMOD ( Rezaali & Fouladi-Fard, 2021 ), and the three-dimensional Lagrangian dispersion models ( Zhang et al, 2020 b) were used to determine the virus-laden-aerosol dispersion under the ambient meteorological conditions to understand the exposure COVID-19 risk in the outdoor environment.…”

Effects of environmental parameters and their interactions on the spreading of SARS-CoV-2 in North Italy under different social restrictions. A new approach based on multivariate analysis

“…Similar conclusions are reported also for smaller droplets (10–100 μm) and, even if at high wind speed (3 m/s) the human thermal plume is destroyed, their deposition on a susceptible person downwind is ten times higher than at low speed (0.2 m/s; Yang et al, 2021 ). Under such a condition (downwind), the wind speed may be a major infection factor as it narrows the infectious plume and relatively-high virion concentrations can be found even at 9 m away from the infective person, at least under the studied conditions (wind speed 0.1–11.5 m/s; Rezaali and Fouladi-Fard, 2021 ).…”
