A study looking at PAHs in urban and rural childcare centers in Nakhon Ratchasima province in Thailand found that total concentrations of 16 PAHs in urban centers was 1.3 times higher, and the estimated value of lifetime lung cancer risk 2 times higher than in rural centres. Distance to road and traffic are the major sources of PAHs. http://iopscience.iop.org/article/10.1088/1755-1315/…/012008
