Aerosol Size Segregated of Tehran's Atmosphere in Iran
Tehran is located in a valley at the foot of the Alborz Mountains in
northern Iran (35 degrees latitude north). Urban expansion in Tehran
resulted from a high rate of population growth and rural-urban
migration combined with a strong tradition of centralization in the
capital. Airborne particulate of Tehran's atmosphere was fractionated
in a 6-stage high-volume cascade Impactor. The first objective was to
measurement of PM in twenty sites in Tehran areas. Other objectives
were to obtain detailed measurements of aerosol size distribution in
Tehran's atmosphere during the 2004 at five sites. In all samples the
PM is high for stage 6 (< 0.49 μm). In Enghelab station mean of
PM value (< 0.49 μ) is 260.97 μg/m3. The highest PM (10-7
μm) concentration is found 115.12 μg/m3 at the Enghelab
station. And the highest PM (3-1.5 μm) was found 40.5μg/m3 at
the Baseej site
