Here you go, buddy. This is from our govt. Heath/Safety website:
Quote:
Over a half-million workers are exposed to fumes from asphalt, a petroleum product used extensively in road paving, roofing, siding, and concrete work. Health effects from exposure to asphalt fumes include headache, skin rash, sensitization, fatigue, reduced appetite, throat and eye irritation, cough, and skin cancer.
There is more detailed info on the site:

Don't even stress over the exhaust fumes. Those won't do
anything to you at 15hrs/wk.
