Multi-element Analysis and Characterization of Atmospheric Particulate Pollution in Dhaka

  title={Multi-element Analysis and Characterization of Atmospheric Particulate Pollution in Dhaka},
  author={Bilkis Ara Begum and Swapan Kumar Biswas and Philip K. Hopke and David M. Cohen},
PIXE (Proton Induced X-Ray Emission) and PIGE (Proton Induced Gamma Ray Emission) have been used to measure the concentration of over 20 elements present in coarse and fine atmospheric particle samples. These samples were collected at a semi-residential site at Dhaka, Bangladesh from July 2002 to June 2003. The multi-elemental capability of PIXE and PIGE enabled the use of these elemental-concentration data to define fingerprints of various coarse and fine particle sources in the atmosphere… CONTINUE READING
