PM-10 represents particles in the air that we consider pollution. These particles might be smoke, dirt, mold, pollen etc. What do these statistics mean for the health of Californians?

Is it that these cities produce more pollutants or is it something about the weather patterns that keep the pollutants in the air?

I would think a lot of this has to do with number of cars and the Sierra Nevadas containing all that pollution on the west coast.
