Lichens are sensitive to pollution, so cannot grow in places with bad air quality. As far as I know. Perhaps someone else can elaborate?

It varies a lot, some lichens are more sensitive than others. There are species you won't find in areas with poor air quality but some species will thrive in the the same conditions. I have even read about lichens growing in areas polluted by toxic slag.
