عنوان انگلیسی "Chemical Composition of TSP and PM10 and their Relations with Meteorological Parameters in the Ambient Air of Shariati Hospital District"
چکیده انگلیسی مقاله Since particulate matter (total suspended particles and particulate matter with median aerodynamic diameter less than 10 µm) is one of the important pollutants in the ambient air of Tehran, the capital of Iran, organic substances, inorganic substances and lead levels in TSP and PM10, correlation between TSP and PM10 concentrations, ratio among the two fractions and relation between TSP and PM10 concentrations with meteorological parameters (relative humidity and temperature) were studied. Twenty-four hour simultaneous sampling of TSP and PM10 has been carried out during the period of 22 December 2001 to 20 April 2002 in the ambient air of Shariati Hospital district. The results showed that inorganic substances were the most abundant component of TSP and PM10 (Approximately 76% and 68%, respectively); 0.21% of total mass for TSP and 0.26% of total mass for PM10 were lead particles; 64% of lead particles had a diameter less than 10 µm; 48% of TSP had a diameter less than 10 µm; while atmosphere relative humidity and temperature were in the range of 50% and 5-10○C respectively, specially on Saturdays in winter and more importantly in inversion conditions, the highest concentrations of TSP and PM10 would be expected.
