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.

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.

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.
