ABSTRACT

Abstract: Mass size distributions of atmospheric aerosol particles were measured at four different regions in outdoor of El-Minia governorate (Upper Egypt). The study was conducted during March 2012 to March 2013. Measurements were performed using low pressure Berner cascade Impactor as an aerosol sampler. The Impactor operates at 1.7 m3/h flow rate with aerodynamic "cut-off" size range from 0.06 up to 16 µm. Measurement results show that the log normal size distributions in outdoor were bimodal in nature corresponding to accumulation and coarse modes The variation obtained at the different sampling sites could be attributed to the different aerosol particles emitted sources in each area environment as well as the climatic outdoor changes.
