Breathing polluted air for even a short period of time can cause some genes to undergo reprogramming, which may affect a person's risk of developing cancer and other diseases, say Italian researchers.
Comparisons of blood DNA samples from healthy workers who were exposed to high levels of airborne particulates at a foundry near Milan revealed that after only three days of exposure, changes occurred in four genes that have been linked to tumor suppression, according to research presented Sunday

This is interesting news. Reprogramming of DNA by pollution chemicals. This could actually mean that the human species can actually evolve to be better suited to absorb these chemicals with no undesired effects.
If so, there may be evidence out there that children born free of the ill effects could have a slight genetic mutation in which these chemicals to not effect their body in a negative way.
We might just be evolving without even realizing it.
