Getting a handle on air pollution`s tiny killers
Many of the particulates in urban air are the result of the gases and vapors that come from evaporated or partially burned gasoline and solvents in paints, among other sources. In the presence of sunlight, these gases react with nitrogen oxides and other chemicals in the air and condense onto bits of dust to form very fine particles. These cause major public health problems and a puzzle for scientists. This article discusses recent research as well as possible US EPA limitations.
