Urea is now injected into the exhaust to neutralize some harmful chemicals. NO2 maybe.
It varies a lot - the amount of pollution you encounter everyday. Around here in the winter and the colder morning, cold engines pollute horrible since the catalytic converter isn't warmed up. I would be worried about asthma if you're breathing in that much.
Have you tried a good filter mask, not a cyclist one but a commercial one.
