Spatial Analysis of the Air Quality Index of Nitrogen Dioxide Gas in Karbala City

Abstract

That the air quality in the city should be a health indicator with a positive indication of the health, purity and freedom of air from gases harmful to the population, there are several factors that contributed to the low air quality index of nitrogen dioxide gas in the city of Karbala, including the lack of green spaces, as well as the emission of gas from various sources, including industrial activities, the increasing number of vehicles and the large number of private generators in the city, maintaining the cleanliness of the ambient air is one of the most prominent challenges faced by the city, the research includes the definition of the air quality index for nitrogen dioxide, then study the spatial and temporal variation of the air quality index of nitrogen dioxide gas in the city of Karbala within the studied sites, the locations of the study area were marked by certain colors, each color indicates a specific situation and then represent them with color gradient maps and for the summer and winter seasons using modern technologies (geographic information systems) in order to know temporal and spatial changes.
