Dirty Diesel

70% of Cancer Risk comes from Diesel Exhaust

No Escape from Diesel Exhaust.Fine particulate matter pollution in the air is responsible for at least 70,000 deaths a year...Studies throughout the world show that people who live or work around diesel engines are at highest risk. But what about the rest of us? Exposure studies suggest that commuters on busy roadways, on diesel transit buses, and on commuter trains receive above-average exposures to fine particles. Studies by California Air Resources Board (CARB) researchers estimate that during the relatively small part of the day when we are in our vehicles, we experience over half of our exposures to ultrafine particles and black carbon.
