Abstract
Abstract Mass size distribution of aerosol particles and the elemental composition of Particulate Matter (PM) were examined in rural and urban areas in El-Minia governorate, Upper Egypt. Low pressure Berner cascade impactor was used to collect aerosol particles. Seven elements were investigated including Ca, Ba, Fe, K, Cu, Mn and Pb using atomic absorption technique. Measurements were performed in El-sharyna village representing a rural site and Maghagha city representing an urban site in El-Minia governorate. Meteorological parameters (temperature and relative humidity) were recorded during the sampling. Elemental mass size distributions were founded as a bi-modal log normal distribution corresponding to accumulation and coarse modes. The mass concentrations of the measured elements ranged from 0.58 ng/m3 (for Ba) to 108.7 ng/m3 (for Fe) at El-sharyna village. The mass concentration at Maghagha city ranged from 0.05 ng/m3 (for Ba) to 96.8 ng/m3 (for Fe).
