STUDIES ON SIZE DISTRIBUTION AND ELEMENTAL COMPOSITION OF ATMOSPHERIC AEROSOL PARTICLE OF EL-MINIA CITY, EGYPT

Using X-ray diffractometer in conjunction with an 8-stage cascade impactor sampler, we have measured the size distribution of elemental mass concentrations in the atmospheric aerosols derived from different sources. Semi quantitative analysis for both atmospheric and car exhaust aerosol particles were performed. Mass size distribution of the particles can be described by bimodal log-normal distribution. It was found that Sr2Sio4 and ZnCl2 are the major aerial contaminant in the fresh aerosol particles. The ratios between coarse and fine particles containing Mn, Fe, Cu, Zn and lead were also studied.
