COVID-19 Implication by Physical Interaction of Artificial fog on Respiratory Aerosols
Journal Title: Advances in Clinical Toxicology - Year 2021, Vol 6, Issue 2
Abstract
Background: Artificial fog consists of small liquid aerosols suspended in air which reduce visibility and reflect light. Artificial fog is used in the film, television, and live entertainment industries to enhance lighting, as a visual effect, and to create a specific sense of mood or atmosphere. Objective: This study investigated the suspension time for liquid respiratory aerosols spiked with tagged deoxyribonucleic acid (DNA) tracers in the presence and absence of glycerin- or glycol-containing artificial fogs. Methods: Liquid respiratory aerosols with tagged DNA tracers were sprayed into a closed environment without and with glycerin- or glycol-containing artificial fog, with air samples taken at regular intervals to determine the decay of tagged DNA tracer over time. The study treatments included Control (no fog), Glycerin Low (~3 mg/m3), Glycerin High (~15 mg/m3), Glycol Low (~5 mg/m3), and Glycol High (~40 mg/m3).
