An increased standard of living in developed and developing countries has brought about a distinct rise in pollution. The problem of air pollution has specifically increased the public's awareness of the environmental and health-related consequences resulting from modern day industrial technology. This detailed collection of works devoted to the most popular methods in elemental analysis of airborne particles offers investigators a comprehensive book on the most common laboratory analytical methods currently used in trace element analysis. Discussed are atomic absorption spectrometry, inductively coupled plasma, atomic emission, particle induced gamma ray analysis, particle elastic scattering and Rutherford backscattering, and neutron activation analysis. Specific sections on quality assurance/quality control and source receptor modeling have also been included.
