Bleach cleaning: indoor emissions, chemistry, and impacts on air quality
By Jimmy Mattila, a graduate student in the Farmer Group at Colorado State University (Twitter: @JimmyMattila) Bleach, an aqueous solution consisting of sodium hypochlorite (NaOCl) and other oxidizers/surfactants, is a commonly used cleaning product in household and workplace environments. The efficacy of bleach stems from its potent antimicrobial and oxidizing properties. Bleach cleaning emits […]
How does flooring type impact your indoor chemistry and indoor microbiology?
This blog post was written by Karen C. Dannemiller, Sarah Haines, and Rachel Adams. Their contact information is at the bottom of this post. Carpets are a favored flooring type. They can be soft, cozy, and warm – and help with keeping noise levels down. Carpet can even help prevent injury. While these attributes are well […]
Total observed organic carbon indoors
Derek found that the total organic carbon concentration was impressively large, three times higher than what you’d find in a typical American city and ten times higher than clean ocean air. He also found that the compounds in the museum were significantly fresher – less oxidized – than those in outdoor air.
An artist who makes clouds. Indoors!
Mr. Smilde’ art is short-lived, just like many oxidants and volatile organic compounds indoors. It can last a few seconds, and then the cloud is gone. He may need to make hundreds of clouds for one photo finish, just like chemists make hundreds (thousands?) of measurements for one manuscript. Indeed, Mr. Smilde’s visual art work resembles a scientific experiment.
New particle formation in the indoor environment
The presence of particles suspended in air is associated with negative health effects, including respiratory and cardiovascular issues. While some particles are emitted directly to the air from a source, such as from combustion, formation of new particles through atmospheric chemical reactions is less obvious to the casual citizen.
Home Diagnosis brings HOMEChem to Public Television: Showcasing the research findings of the Sloan Foundation’s HOMEChem experiment and Chemistry of Indoor Environments
By Grace Lunsford HOMEChem will soon be making its national broadcast debut in Season Two of Home Diagnosis in 2020. Hosted by Grace and Corbett Lunsford of the Youtube Channel “Home Performance”, they helped tell the story through dozens of videos made at the HOMEChem/UT Test house in 2018. “We are so excited to have […]

The report from Kaunas: ISES-ISIAQ 2019
This blog post was written by Erica Marie Hartmann, Assistant Professor at Northwestern University (profile, Twitter). Last week, the International Societies of Exposure Science (ISES) and Indoor Air Quality and Climate (ISIAQ) had their joint meeting in Kaunas, Lithuania. The meeting featured a lot of great research on topics ranging from the thermal comfort of […]
