Air Pollution
Air Pollution Sources Overview – January 24, 2019
“[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
Air Pollution Sources Overview – January 24, 2019
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.
