Prediction and Properties of Airborne Dust Arising from Mining Sites
- 245 - Using Lead Isotopes to Identify Sources of Metal and Metalloid Contaminants -- Betterton
Release Date: 05/06/2015
By sampling wind-blown dust and aerosol, researchers from the University of Arizona Superfund Research Program (UA SRP) have measured airborne metal and metalloid contaminant dispersion patterns from mining operations. While using an existing technique in a new way, the UA SRP researchers measured the extent of soil contamination near a mine and smelter while verifying the use of lead isotope analysis to identify contaminant sources.
- 202 - Size-resolved Chemical Characterization of Atmospheric Aerosols -- Betterton
Release Date: 10/05/2011
Some mining operations release dust containing hazardous elements like arsenic and lead into the air. Scientists have developed a new approach for detecting these airborne pollutants, assessing their potential health impacts and reducing human exposures.
