>>18141805, >>18141762 (Both PB) CALL FOR A DIG ON VOC'S
Pubmed Article:
"Quantifying speciated concentrations and emissions of volatile organic compounds (VOCs) is critical to understanding the processes that control indoor VOC dynamics, airborne chemistry, and human exposures. Here, we present source strength profiles from the HOMEChem study, quantifying speciated VOC emissions from scripted experiments (with multiple replicates) of cooking, cleaning, and human occupancy and from unperturbed baseline measurements of the building and its contents."
….
The building and its contents were the dominant emission source into the house, with large emissions of acetic acid, methanol, and formic acid. Cooking emissions were greater than cleaning emissions and were dominated by ethanol. Bleach cleaning generated high emissions of chlorinated compounds, whereas natural product cleaning emitted predominantly terpenoids.
So what is the HomeChem Study? [https://www.colorado.edu/lab/vance/homechem-open-house]
You are invited to an Open House Event for the HOMEChem study on Friday, June 22, 2018.
The Study
In the United States, as well as in most of the developed world, people spend about 90% of their time in indoor environments. Not only are we impacted by the air we breathe and the surfaces we touch, but we also constantly change and influence the indoor environment around us. Although many research efforts have focused on assessing the presence and quantity of chemical air pollutants that affect the indoor air quality, few comprehensive studies have attempted a deeper exploration into how indoor air chemical compounds may interact and transform throughout a normal day of activities.
The HOMEChem experiment (House Observations of Microbial and Environmental Chemistry) will take place in the month of June 2018, incorporating measurements from over 15 research groups from 9 universities to identify the most important aspects of the chemistry that controls the indoor environment. The HOMEChem field study is expected to kick-start and energize the Chemistry of Indoor Environments community of scientists, while also answering interesting preliminary science questions on the chemistry of indoor environments in a real-world experimental setting. This brings an excellent opportunity for outreach to the broader scientific community and other stakeholders, such as other funding agencies, the local and national media, and the public.

From the linked "more information" site:
Volatile Organic Compounds (VOCs) are a much broader group of gas-phase species with a wide variety of sources, including the paint on our walls, our cleaning products, our beauty products, our meals, and even our skin. Each of these sources–and many more–can contribute molecules that form a chemical soup around us. VOCs have the potential to react with the oxidants described above to form a variety of different products. The VOCs and their products can range from lighter and more volatile species that are quickly distributed throughout a room, to heavier and stickier species that have the potential to condense onto surfaces like walls, fabric, and humans, or to participate in the formation of particles. Many VOCs and their products have a negative impact on human health. By measuring a large range of Volatile Organic Compounds during HOMEChem, we hope to improve our understanding of VOC sources and fates within the indoor environment.
Participants included; HOMEChem researchers are from the University of Colorado Boulder; Colorado State University; the University of Texas at Austin; Drexel University; Syracuse University; Indiana University Bloomington; the University of Toronto; the University of California, Berkeley; the University of California, San Diego; the University of Massachusetts; Harvard University; Washington University in St. Louis Engineering; and The College of William & Mary.
Instruments being used during the experiment have been loaned by Handix Scientific, Airmodus,
Airboxlab, and the National Institute for Occupational Safety and Health (NIOSH).
