* ppm - parts per million
** Tiny solid or liquid particles of soot, dust, smoke, fumes, or mists. The size of the particles (10 microns or smaller, about
0.0004 inches or less) allows them to enter the air sacs deep in the lungs where they may be deposited to the result in
adverse health effects. Also causes visibility reduction. Data listed here are reported as 24-hour average concentrations in
ug/m3 (weight of particles in micrograms per one cubic meter of air).

Smog Kills. According to the South Coast Air Quality Management District, an estimated 1,600 people die prematurely
each year in the greater Los Angeles region due to smog. Thousands more suffer temporary or long-term health effects
and millions more are at least inconvenienced.
