A Clothing Conundrum

Morrison remained at Berkeley for his PhD with Bill Nazaroff. Here, he took a more quantitative look into carpet and ozone chemistry, measuring yields of pollutants formed by carpets and making predictions to feed into a model. Morrison still likes to incorporate modelling in all of his projects. “If there isn’t a modelling component, I don’t feel like I know what is going on,” he explains.

Cleaning floors with bleach significantly alters indoor air chemistry

“When we wash with bleach, the oxidation occurs not only on the surface we are washing but everywhere else too”. Carslaw agrees, adding that bleach washing produces a much “wider group of chemicals than previously thought”, and that “chemists need to work much more closely with toxicologists” in order to determine the health impacts of the resulting, chemically-altered air.

A Model Life

Carslaw furthers our knowledge by working with postdoc, Magdalena Kruza and PhD student, Zixu Wang, to use and develop her detailed chemical model with 31,000 lines of code, to simulate the chemistry of indoor air in exquisite detail.
