Human skin oil is rich in ozone-reactive compounds, including squalene and unsaturated
acyl groups of free fatty acids, glycerols, and wax esters. Squalene and unsaturated acyl …

Multiphase chemistry occurs between chemicals in different atmospheric phases, typically
involving gas–solid and gas–liquid interactions. The importance of atmospheric multiphase …

Ozone concentrations tend to be substantially lower indoors than outdoors, largely because
of ozone reactions with indoor surfaces. When there are no indoor sources of ozone, a …

Ozone reactions on human body surfaces produce volatile organic compounds (VOCs) that
influence indoor air quality. However, the dependence of VOC emissions on the ozone …

One strategy for mitigating the indoor transmission of airborne pathogens, including the
SARS-CoV-2 virus, is irradiation by germicidal UV light (GUV). A particularly promising …

While vehicle cabin environment significantly impacts human health, systematic studies on
this important microenvironment are lacking. Here, we conduct a 12-day field observation of …

Unsaturated triglycerides found in food and skin oils are reactive in ambient air. However,
the chemical fate of such compounds has not been well characterized in genuine indoor …

Humans spend most of their time indoors, where they are exposed to many volatile organic
compounds (VOCs). Exposure to indoor VOCs has been linked to adverse health effects …

Energy-efficient residential building standards require the use of mechanical ventilation
systems that replace indoor air with outdoor air. Transient outdoor pollution events can be …

Carbon dioxide (CO 2) and methane (CH 4) are important greenhouse gases in the
atmosphere and have large impacts on Earth's radiative forcing and climate. Their natural …
