Project Highlight: A New Community Model for Indoor Air Chemistry: COMODIAC
"This project aims to provide the Chemistry of Indoor Environment (CIE) program and the wider indoor air quality community, with an open source model that will allow them to explore indoor air chemistry processes in detail."

Multiphase Chemistry Controls Inorganic Chlorinated and Nitrogenated Compounds in indoor Air during Bleach Cleaning
James M. Mattila, Pascale S. J. Lakey, Manabu Shiraiwa, Chen Wang, Jonathan P.D. Abbatt, Caleb Arata, Allen H. Goldstein, Laura Ampollini, Erin F. Katz, Peter F. DeCarlo, Shan Zhou, Tara F. Kahan, Felipe J. Cardoso-Saldaña, Lea Hildebrandt Ruiz, Andrew Abeleira, Erin K. Boedicker, Marina E. Vance, and Delphine K. Farmer, Environmental Science & Technology
"We report elevated levels of gaseous inorganic chlorinated and nitrogenated compounds in indoor air while cleaning with a commercial bleach solution during the House Observations of Microbial and Environmental Chemistry field campaign in summer 2018. Hypochlorous acid (HOCl), chlorine (Cl2), and nitryl chloride (ClNO2) reached part-per-billion by volume levels indoors during bleach cleaning—several orders of magnitude higher than typically measured in the outdoor atmosphere. Kinetic modeling revealed that multiphase chemistry plays a central role in controlling indoor chlorine and reactive nitrogen chemistry during these periods."

How does flooring type impact your indoor chemistry and indoor microbiology?
By Karen C. Dannemiller, Sarah Haines, and Rachel Adams
"carpet acts an important indoor reservoir, and therefore serves as both a sink and source for chemical and biological agents. Carpet has a substantial surface area, and can support chemical transformation. Carpet manufacturing, recycling, and clean-up also has an important environmental impact. In the future, strategies and technologies could be developed to enhance carpet design in order to maintain what we love about carpets while reducing human exposure to indoor contaminants."
