Abstract

Abstract:

The present study reports characterization of some gaseous and particulate pollutants in three different studied sites around Quesna Industrial City, in Monufia Governorate, Egypt. Samples were collected monthly from December 2018 to November 2019 in all studied sites. Seasonal mean concentrations (μg/m3) of SO2, NO2 and NH3 were higher in spring, summer and winter, respectively, with maximum concentrations recorded at site 1 (urban–industrial area). Dust fall concentrations were higher in autumn, with maximum values recorded at site 1 followed by site 3 (traffic-residential area). The monthly mean concentration of dust varied from 17.41 to 221.28 (g/m3/ month). Dust fall, have no Air Quality Limit value. However, some countries normally state that when dust fall values exceed 10 g/m3 per 30 days, the area is considered unclean (polluted).

The chemical composition of dust fall including SO42- , CL-, NH4- and NO2- (%) was analyzed for samples collected from the three studied sites. Correlation coefficient values of the relationships between the chemical constituents of collected dust samples indicated that the total soluble and insoluble matter were negatively correlated (P ≤ 0.01). A significant negative correlation was found between SO2 and NO2 at 0.05 significant level for samples collected from semi-residential area.
