Look up Chinese cancer villages, this is the real scary pollution. Thankfully we have the EPA in America (and unions, and many other things) that have defended the US population from mass poisonings. This is evidence that our laws and regulations are working well here in the US. As it seems it's getting harder and harder to find "cancer causing something" in the US. Which is why maybe we are now finally getting around to finding "nontraditional source of secondary organic aerosol precursors".
