Exposure science

Exposure science is the study of how people come into contact with things like pollutants, chemicals or even viruses. Imagine you're playing in a sandbox and some sand gets in your mouth. That's a form of exposure. Scientists want to know how much sand you might have eaten and how that might affect your health. They use special tools, like sensors and monitors, to measure or track these things. They might also collect information about how often or how long people are exposed to things. All of this information can help scientists figure out which things are safe for people, and which things might be harmful if we're exposed to too much of them.
