Ever heard of or seen the following?

There are thousands of chemicals on the list... most I don't recognize, but couple I do... Diesel Engine Exhaust and Gasoline Engine Exhaust. Ever been exposed to that? Yes? Should we shut down all transportation because of the risk?
Granted, there is no x number of years of half life, but who needs to worry about the half life when you're exposed to it all the time anyway?!?
