What is Exposure Science?

Exposure science considers people's varied activities and multiple exposure pathways
Exposure science studies the contact of target organisms, such as people, to pollutants and other agents in the environment. We are exposed to a myriad of toxic substances through our daily life. Some compounds are released to the outdoor environment, such that people living in particular communities with significant pollution sources or those living near busy roads are more highly exposed. Some are released in the indoor environment, such that an individual's behaviors and consumer product choices influences their exposures.

Several important questions can be answered using exposure science. Will the emissions of a new facility cause exposures that might result in adversehealh effects? What routes of exposure (ingestion, inhalation, dermal exposure) are most important for a compound of interest? How do we classify individuals by exposure for an epidemiology study to determine if exposures are related to health effects?


In addition, UC Davis has scientists developing cutting edge tools to measure exposures in the environment. We also have extensive research in air pollution fate and transport as well as health effects. Our Western Center for Agriculture provides close ties to the agricultural communities. UC Davis faculty lead two of the premier studies on environmental causes of Autism. All of these provide unparalleled opportunities for collaboration.



Exposure science links the environment to the body, allowing us to relate sources of pollution in the environment to disease. Exposure Science helps us understand how a particular source to the environment will cause harm. Exposure scientists can also work with epidemiologists to help determine what sources of exposure may have caused a particular delay.

Exposure science shows how and where people spend their time and how this influences their exposures to pollutants in the environement.
