Soil derived dust as a source of silica: aerosol properties, emissions, deposition, and transport.
Quartz is an abundant mineral in wind generated dust throughout the United States. Of the 18.9 million tons of particles smaller than 10 microns (PM10) dust emitted into the atmosphere by the wind, a significant fraction is silica. Transport of some of this silica to populated areas is possible.
