Abstract. The Forests gAses aeRosols Clouds Exploratory (FARCE) campaign was conducted in March–April 2015 on the tropical island of La Réunion. For first time, several scientific teams from different disciplines collaborated to provide reference measurements and characterization Réunion vegetation, volatile organic compounds (VOCs), biogenic VOCs (BVOCs), (bio)aerosols composition clouds, with a strong focus Maïdo mountain slope area. main observations obtained during this 2-month intensive...
Abstract An accepted murine analogue for the environmental behavior of human SARS coronaviruses was aerosolized in microdroplets its culture media and saliva to observe decay airborne infectious potential under relative humidity (RH) conditions relevant conditioned indoor air. Contained a dark, 10 m3 chamber maintained at 22°C, hepatitis virus (MHV) entrained artificial particles that were size distributions mimic SARS-CoV-2 expelled from infected humans’ respiration. As judged by...
Fluorescent aerosol cytometry (FAC) was compared to concurrent recovery of airborne β-N-acetylhexosaminidase (NAHA) and quantitative polymerase chain reaction (qPCR) for the respective ability these methods detect significant changes in fungal loads response building renovations. Composite, site-randomized indoor samples fungi measurements were acquired from more than 70 occupied classrooms 26 different public schools Colorado Rocky Mountain Front Range region United States. As judged by...
Airborne murine coronavirus was assessed for its sensitivity to the vapors of chemicals commonly used disinfect indoor surfaces. As a model chemical airborne SARS-CoV-2, infectious potential Mouse Hepatitis Virus (MHV) tracked in presence following pure vapors, each which below permissible exposure limit (PEL) as regulated by US National Institute Occupational Safety and Health (NIOSH): <50 ppmv glycol; <1ppmv HOCl; H2O2. Along with growth media, MHV aerosolized particle size distribution...

Solutions containing hypochlorous acid (HOCl) are common cleaning agents that when aerosolized and/or applied directly to indoor surfaces, partition into vapor where they may retain disinfecting potential even at trace levels (< 1 ppmv). Indoor HOCl exposures difficult estimate because of their reactivity and the limited availability portable, affordable, accurate detection methods appropriate for use in occupied built environments. In response, a sensitive, fluorescence-based method...
