Abstract

This study presents an assessment of the air quality in Assiut city, Egypt; in summer and in winter seasons. Full-scale measurements at four selected sites located within Assiut city are carried out using a mobile monitoring unit. The major air pollutants for which the variation of daily concentration were obtained from full-scale measurements are; sulphur dioxide (SO2), nitrogen dioxide (NO2), particle matter (PM10) and carbon monoxide (CO). The air quality analysis has been performed using the Air Quality Index (AQI) based on the four measured pollutants. The assessment criteria of air quality are classified according to the categories set by EPA as: good, moderate, unhealthful, very unhealthful and hazardous. The study results indicate that; the air pollution levels in Assiut city reached very high concentrations due to a combination of emissions from a number of different sources and adverse weather conditions. The determined AQI value exceeded the standard value of 500 in summer. It is about 2.5 times the extreme limit of 500 in almost all sites. In winter, the AQI values are below 500 in all measurement sites. However, in both seasons, the AQI values reflect hazardous air quality conditions in almost all measurement sites. The pollutant that is responsible for the worse air quality in almost cases is the suspended particulate matter (PM10). Such results reflect that the main air pollution problem in Assiut, Egypt is the level of dust.
