HAZARD OF INDOOR POLLUTION INSIDE OUR HOME IN CAIRO GOVERNORATE

Abstract

Abstract During the last three decades, many efforts have been made to protect populations from harmful exposure to outdoor pollutants. However, people spend about 80-90% of their time in various indoor ambiences (i.e. homes, offices, restaurants, etc.) and the quality of indoor airis an important factor influencing human health. we measured indoor air pollutants levels in homes in Cairo-Egypt to estimate the different sources of pollutants andwe measured the concentration of following indoor air pollutants H2S,No2,Co,SO2 and particulate in four residence areas two of them near industrial area which are shoubra el khiema and Helwan ,the other two residence area were Heliopolis Nasr city to use these data to estimate the health burden that is attributed to air pollution within homes, we collected 30 sample from 30 home in each area using gas analyzer and particulate analyzer (Thermo dust meter).the analyses of the results demonstrated that there was a significant increase of Co level in industrial area with main ±SD: 6.1±8.3 than non-industrial area with main ±SD: 2.7±0.7 with p-value= 0.002, aextremely statistically significant increase of H2S level in industrial area with main ±SD: 0.05±0.01 than non-industrial area withmain ±SD: 0.01±0.07 with p-value= 0.0001, a extremely significant increase of SO2 level in industrial area with main ±SD: 0.05±0.01 than non-industrial area with main ±SD: 0.03±0.02 with p-value= 0.0001,extremely significant increase of NO2 level in industrial area with main ±SD: 0.2±0.09 than non-industrial area with main ±SD: 0.1±0.02 with p-value= 0.002 and significant increase of particulate level in industrial area with main ±SD: 0.3±0.04 than non-industrial area with main ±SD: 0.2±0.03 with p-value= 0.002.
