Integrated Assessment of Air Pollution in Tehran, Over the Priod From September 2008 to September 2009
Background: Air pollution is a major problem in urban"industrial areas, like Tehran, and has several impacts on human health. This study aimed at assessing concentrations of criteria air pollutants (CO, SO2, NO2, O3, PM10) in Tehran, extracting patterns of hourly, daily, weekly, and monthly var...
