Ahmad, S.S., Büker, P., Emberson, L., Shabbir, R. (2011). Monitoring nitrogen dioxide levels in urban areas in Rawalpindi, Pakistan. Water Air and Soil Pollution 220, 141-150.
Nitrogen dioxide is an important gaseous air pollutant. It plays a major role in atmospheric chemistry, particularly in the formation of secondary air pollutants, and contributes to environmental acidification. A comprehensive assessment of NO2 levels in the atmosphere is required for developing effective strategies for control of air pollution and air quality improvement. Air pollution is a serious problem in all major cities of Pakistan and needs to be addressed to minimize detrimental effects on human health and urban vegetation. In this research, we focused on the monitoring of NO2 levels in the urban environment of Rawalpindi city.
In this study, average concentrations of NO2 were determined using diffusive passive sampling in the city boundaries of Rawalpindi.
The aims of this work have been:
to monitor the NO2 concentration in Rawalpindi city,
to determine average NO2 concentrations for different parts of the city and
to investigate the influence of meteorological variables on the measured concentrations.
The monitoring of NO2 is critically important, in order to assess the potential effect of NO2 on human health and ecosystems, as well as developing strategies for the effective control of NO2 pollution.
