Air Pollution Problems and Diseases Caused by Hazardous Gases in Quetta, Pakistan|
Ilyas, Syed Zafar; Nasir, S.M. & Raza, S.M.
Nowadays air over major cities throughout the world has become over burdened with gases
produced by automobiles. The death rate due to automobiles pollution is increasing rapidly in the metropolitan
areas. With passage of time people realized that polluted air had serious effects on their health, climate and
economics. Weather and climate have the integrated impact on human activities which are resulting in worldwide
concentration of the particulate of environmental pollution viz. chloroflorocarbons (CFCs), carbon dioxide,
methane, nitrogen oxide, lead and several other dust and gaseous particles. The present study is an attempt to
exploit air problems and diseases caused by the lead, CO, NH3,NO2 and SO2 of the Quetta city. Data at different
locations recorded for the pollutants,.i.e., CO, NH3,NO2, Pb and SO2 for a period of two months have been
analyzed by two indices ,.i.e. air pollution control status index (APC-Status index) , urban air quality index (Urban
AQ index) and the determination of Pb (lead) emitted from vehicle at roadside in Quetta city was analyzed for two
months without any interval at nine different stations. We conclude from our results that blood pressure, ENT
(eye, nose and throat), fatigue, gastrointestinal, diseases and cancer were highly correlated with lead distribution.
We also conclude that the motor vehicles/ automobiles now constitute the main source of air pollution. The coal
burning, kiln backing in furnaces and natural gas burning are the other sources of air pollution.
