Abstract

Ironically, air pollution is one of the most serious environmental issues of Pakistan. In this study, different cities including Lahore, Islamabad, Karachi, Peshawar, and Quetta were selected to analyze the relationship of different gases in air such as carbon monoxide CO, nitrogen dioxide NO2, sulphur dioxide SO2, methane CH4, ozone O3, and particulate matter PM. The automatic ambient air data of the above mentioned cites were obtained from air quality monitoring stations installed in Pakistan Environmental Protection agency (Pak-EPA) and as well as provincial EPAs. Therefore, the results of air gases were quite alarming such as Lahore was found to be SO2 (200 µg/m3) and PM 2.5 (85 µg/m3) compared with the standard ambient air geese values. Subsequently, in Peshawar city CH4 gas was analysed (7510.29 µg/m3) was ten times higher than Pakistan National Environmental Quality Standard (NEQS) values.  This conclusive evidence of air pollution in Pakistan cities will lead many diseases, such as cardiovascular, cancer, and many respiratory diseases. In conclusion, if no suitable and efficient ways are adopted at government level the situation will very worst in the nearly future.
