Squalene Depletion in Skin Following Human Exposure to Ozone under Controlled Chamber Conditions

A major component of human skin oil is squalene, a highly unsaturated hydrocarbon that protects the skin from atmospheric oxidants. Skin oil, and thus squalene, is continuously replenished on the skin surface. Squalene is also quickly consumed through reac ...

Resuspension of inhalable particles from clothing: A manikin-based chamber study

Dusan Licina, Shen Yang

Clothing plays a significant role in facilitating inhalation exposure to particulate matter (PM). Nevertheless, there is a lack of studies investigating PM resuspension from clothing. This study aims to quantify size-resolved PM resuspension rate (RR) from ...
