Air Pollution


“[Particulate matter] is a mixture of

substances that include … carbon and

metals … nitrates, organic compounds,

sulfates, and complex mixtures such as

diesel exhaust and soil. Some particles

are emitted directly into the atmosphere.

Others … result from … physical and

chemical processes in the atmosphere.”1

Vehicle Impacts on Community


Previously, we showed a slide

breaking out the contribution from

mobile sources – cars, trucks, etc.

The District has developed a tool that

estimates vehicle risk near busy

roadways (highways)

Numbers displayed for some major

intersections represent increased

cancer risk in # per million people.
