Source identification of airborne elements in industrial area by XRF technique

In this work, X-ray fluorescence was applied to analyze aerosol samples collected from indoor and outdoor atmosphere Sudan Mint Company in Khartoum industrial area. The collected X-ray spectra were analyzed using AXIL program. The concentration of Calcium, Chromium, Iron, Cobalt, Nickel, Copper, Zinc, Bromine, and Lead were determined compared to the prepared standards. The accuracy of the results was crosschecked using Atomic Absorption Spectrometer. Various receptor models were used in aerosol source identification and apportionment. In this study, the Zinc and Copper showed highest concentration in the indoor and outdoor samples. The correlation between the elements showed that the elements were contributed by the same source. The principal factor and enrichment factor confirms the elements in industrial area aerosol are industrial emission and soil dispersion. The data can be used by occupational health department to assist in drafting policies on work places to control pollutants
