Can working in a building that's in a shopping center expose you to auto exhaust particulates and such?

Question

Or are the air conditioning units in these places generally filtered to dredge out the quagmire of toxins and pollutants inundating the outside air in these areas?

Answer 1

Just living day to day will expose everyone.

Answer 2

There will be some exposure, but it will be quite minimal.  Most likely less than in your own home.
