Narrator: This is Science Today. Young children are more susceptible than adults are to the harmful health effects of pesticides. Because of this, many regulatory agencies are taking a special interest in protecting children from harmful pesticide exposure. Environmental health scientist, Thomas McKone of the University of California, Berkeley, is involved in a project looking into the use of pesticides and the levels in people.
McKone: The overall goal of the project is to look at health effects, but a key part of that is to understand where it's coming from when you see it in the children. So they're taking a lot of blood samples and tissue samples to look at levels of pesticides.
Narrator: In the past, McKone says researchers have always looked at adults to understand the relationship between intake of chemicals and levels in our environment.
McKone: And that doesn't help us when you look at children because they interact in a much more intimate and oral way with their environment. So they have a lot more contact with surfaces and of course, a lot of the pesticides - we find them in the dust, we find them on surfaces inside of homes.
