Indoor Particulate Matter And How to Limit Your Exposure
By Julia Bakker-Arkema and Marina Vance. This video was entered in the 2019 AAAR conference video competition and won 1st prize! Congratulations to Julia and Nina. We see and experience particulate matter, or aerosol particles, all around us. Aerosol particles make up the smog we see on our morning commutes, the trails of smoke that rise […]
Organic compounds in indoor air like to accumulate in paint
By Lucas Algrim, a recent PhD student in Paul Ziemann’s research group at University of Colorado Boulder. A range of volatile organic compounds (VOCs) can be found in the indoor environment. Many VOCs will be ventilated out of the building by the air handling system, but they can also sorb to indoor surfaces, in other […]

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.

One of the biggest conclusions from the ARTISTIC campaign is how much people and our indoor activities impact indoor air quality, from the emissions on our breath, the emissions that come from our activities and the chemical products that we use; these things all change the chemistry of indoor spaces.
