Author Description

In Pakistan air pollution is increasing at an alarming rate that poses some serious threats to health issues. Dust and smoke particles are generally twice the world average and five times higher than the developed world but unfortunately no serious action has yet been taken in this concern. This book has been completed with the help of literature review and field testing by the help of portable digital detectors. The available data on air quality for the twin cities of Pakistan (Rawalpindi/Islamabad), especially information regarding input sources were collected from all the relevant organizations/departments and after that the actual `experimental work was done. Analysis of collected data was carried out in general to signify background of air quality in these cities. Different points with respect to traffic and industrial loads were selected and tested for different selected parameters. After that a thorough experimental research work was carried out on these locations to study the air quality. Air quality degradation due to road transportation and industrialization trend was checked in the field. Effects of traffic flow on air quality in these cities due to increase in number of vehicles per year was studied experimentally for better understanding of the phenomena. Sampling was performed in detailed to check the quantity of CO2, NOx, HC and CO etc. As per study of JICA in the year 2000, examination of SO2, CO, SPM data shows pollution levels exceeding the international standards. The research work done showed gradual increase in the air pollution in both cities with a percentage of 10% to 15%. Experimental work presented in the graphical form and computer models in the book based on excel sheet proposed on the collected data. Proper solutions are proposed in the book to improve the air quality in these cities. Results mentioned were analyzed graphically to explore the trends through interpolation estimated value of these pollutants which are predicted to highligh
