Claim: Exposure to particulate air pollutants associated with numerous cancers

Claim: Exposure to particulate air pollutants associated with numerous cancers

Ridiculous. Here’s a one big reason.

In Beijing and other Chinese cities, PM2.5 levels average 100 µg/m³. This study claims that for every 10 µg/m³ of increased exposure to PM2.5, the risk of dying from any cancer rose by 22 percent. So Chinese cities should be witnessing more than three times as many cancer deaths as low PM2.5 areas. Also, about 50% of Chinese men smoke and cigarette is worth 10,000 to 40,000 µg worth of PM2.5 exposure in 10 minutes. If PM2.5 is so carcinogenic, where’s all the cancer?

And of course, what would this say about EPA’s human testing program which included exposing human guinea pigs to PM2.5 levels as high as 750 µg/m³?
