What I'd like to see is a study of gasoline vs. diesel exhaust exposure in a "normal" concentration environment, as far as cancer rates go.
My understanding is that gasoline particulates, due to the particulate matter being smaller in mass, hung in the air for longer (exposing more people) and went further into the lungs (causing more damage) than diesel particulates.
