Narrator: This is Science Today. The U.S. Environmental Protection Agency has awarded a 40 million dollar grant to establish five new national air pollution centers to study how particulate matter affects human health. Two of these centers will be located at University of California campuses; one at UCLA and another at the University of California , Davis . Kent Pinkerton is co-director of the San Joaquin Valley Aerosol Health Effects Center in Davis .
Pinkerton: A lot of the research that we would like to do is to look at actual problems that exist in the environment and work at that level and in trying to understand what are the specific components within the environment that might help us to better understand the consequences of inhaling of those particles.
Narrator: At the same time, Pinkerton says they would like to break down those studies and look at a single, chemical compound.
Pinkerton: So that we might be able to look at how that particular component may contribute to the overall health effects that we see in the environment.
Narrator: For Science Today, I'm Larissa Branin.
