Exposure science: Routes of exposure-inhalation

Research output: Chapter in Book/Report/Conference proceedingChapter


Inhalation exposure increases the body burden of airborne pollutants. People spend 90% of their time indoors, so indoor air levels often drive exposures. The concentrations of many air pollutants indoors and in enclosed settings are often higher than outdoors since even small emissions within a limited volume can lead to elevated concentrations. Activities that people engage in and consumer product use can result in emission sources being in very close proximity to people contributing to the overall inhalation exposure. It is necessary to understand the time spent and the air concentrations in each microenvironment people encounter over the course of a day to determine inhalation exposures, and to develop a risk management plan to reduce those exposures. Both measurement and modeling approaches have incorporated a variety of exposure science principles to calculated inhalation exposures. As new products are brought into use it is important to recognize how they will actually be used and the resulting emissions that can lead to exposures and adverse health outcomes. Accurate determination inhalation exposure on an individual and population basis is a key component of environmental and occupational epidemiology studies as well as risk assessment and risk management applications done to protect public health.
