TI  - Metal and Metalloid Contaminants in Atmospheric Aerosols from Mining Operations.
PG  - 145-157
AB  - Mining operations are potential sources of airborne metal and metalloid 
      contaminants through both direct smelter emissions and wind erosion of mine 
      tailings. The warmer, drier conditions predicted for the Southwestern US by 
      climate models may make contaminated atmospheric dust and aerosols increasingly 
      important, with potential deleterious effects on human health and ecology. Fine 
      particulates such as those resulting from smelting operations may disperse more 
      readily into the environment than coarser tailings dust. Fine particles also 
      penetrate more deeply into the human respiratory system, and may become more 
      bioavailable due to their high specific surface area. In this work, we report the 
      size-fractionated chemical characterization of atmospheric aerosols sampled over 
      a period of a year near an active mining and smelting site in Arizona. Aerosols 
      were characterized with a 10-stage (0.054 to 18 mum aerodynamic diameter) multiple 
      orifice uniform deposit impactor (MOUDI), a scanning mobility particle sizer 
      (SMPS), and a total suspended particulate (TSP) collector. The MOUDI results show 
      that arsenic and lead concentrations follow a bimodal distribution, with maxima 
      centered at approximately 0.3 and 7.0 mum diameter. We hypothesize that the 
      sub-micron arsenic and lead are the product of condensation and coagulation of 
      smelting vapors. In the coarse size, contaminants are thought to originate as 
      aeolian dust from mine tailings and other sources. Observation of ultrafine 
      particle number concentration (SMPS) show the highest readings when the wind 
      comes from the general direction of the smelting operations site.
