摘要

Increase in economic development actively results in the industrialrevolution of the late 18 th century. Air is being filled with both gaseous andparticulate pollutants toxic to life. With passage of time people realized thatpolluted air had serious effects on their health, climate and economics.Weather and climate have the integrated impact on human activitieswhich are resulting in worldwide concentration of the particulate ofenvironmental pollution viz.Chlorofloro, Carbons, Carbon dioxide, Methane,Nitrogen oxide and several other dust and gaseous particles.Now-a-days air over major cities throughout the world has become overburdened with gases produced by automobiles. The death rate due to automobilespollution is increasing rapidly in the metropolitan areas.The present study is an attempt to exploit urban air problems of theQuetta city. Data at different locations recorded for the pollutants,.I.e., CO,NH3,NO2 and SO2 for a period of two months have been analyzed by twoindices,.I.e. air pollution control status index (APC-Status index) and urban airquality index (Urban AQ index). We conclude from our results that the motorvehicles/ automobiles now constitute the main source of air pollution.
