Ultrafine air pollution particles are tiny – about 0.1 micron in diameter or roughly one-thouh the width of a human hair. These particles are generated from gas and diesel motor vehicle engines, biomass burning and energy production. The study is the first to consider the effects on people of long-term exposure to ultrafine particles.
