Nitrogen Dioxide is widely used in air quality
assessment. NO2 is an important gaseous air
pollutant that plays a critical role in atmospheric chemistry. Keeping in
view its critical importance for atmospheric chemistry and human health,
information on ambient levels of NO2 in
Islamabad will be monitored using Diffusion Samplers. Diffusion Samplers
provide a convenient alternative for measuring ambient NO2
in a highly cost effective manner. Diffusion Sampler is a simple cheap
device, which is independent of power supply. The present study deals with
24 hours measuring of NO2 concentration
along road side and adjacent residential areas.
In recent years, interest in NO2
as an air pollutant is growing not only because of its phytotoxic nature but
also on account of growing evidence of its adverse effect on human health.
