STUDY AND ANALYSIS FOR PRECEPITATE DUST PARTICLES IN RESIDENTIAL SECTOR AT AL-NAJAF AL-ASHRAF CITY

Abstract

This paper has been carried out to study the precipitate dust particles in residential area at Al-Najaf Al- Ashraf city, with special site of Alsaad quarter. It also studied the impact of the most important climatic characteristics ( such as temperatures, wind speed, humidity and evaporation, and rain) with rate affecting the collection the dust particles and to identify the levels of generation at the city. Also the climatic properties of city had been analyzed that resulted in Knowing the range of dust collected. And to identify the environmental impact of the collecting precipitate dust particles, samples were taken at Alsaad quarter by using metal cylinder, for three years from 2007 until 2009, at monthly rate for each sample. The most important results of this paper are the seasonal changes of the climate with anthropogenic activities accompanied by seasonal changes in dust quantities. Finally, the conclusions and recommendations which help the reducing of the risks of this important problem were presented.
