This critical review describes the squalene-ozone (SqOz) reaction, or squalene ozonolysis.
Ambient ozone penetrates indoors and drives indoor air chemistry. Squalene, a component …

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 …

Human-emitted volatile organic compounds (VOCs) are mainly from breath and the skin. In
this study, we continuously measured VOCs in a stainless-steel environmentally controlled …

Hydroxyl (OH) radicals are highly reactive species that can oxidize most pollutant gases. In
this study, high concentrations of OH radicals were found when people were exposed to …

Here, we investigated the use of breath-borne volatile organic compounds (VOCs) for rapid
monitoring of air pollution health effects on humans. Forty-seven healthy college students …

Natural window ventilation is frequently employed in schools in Europe and often leads to
inadequate levels of human bioeffluents. However, intervention studies that verify whether …

Ammonia (NH3) is typically present at higher concentrations in indoor air (∼ 10–70 ppb)
than in outdoor air (∼ 50 ppt to 5 ppb). It is the dominant neutralizer of acidic species in …

Ozone reaction with human surfaces is an important source of ultrafine particles indoors.
However, 1–20 nm particles generated from ozone–human chemistry, which mark the first …

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 …

Humans spend approximately 90% of their time indoors, impacting their own air quality
through occupancy and activities. Human VOC emissions indoors from exercise are still …
