title: Concentrations and source assessment of some atmospheric trace elements in northwestern region of Tehran, Iran.
abstract: Outdoor concentrations of some elements such as iron, aluminum, magnesium, titanium, copper, zinc, lead,manganese, sulfur, chromium and arsenic in PM(10) and PM(2.5), was evaluated at four points in north-western part of Tehran in winter 2007. The total concentration of the elements in PM(10) and PM(2.5) at the north Karegar avenue found to be as high as 82.05 and 60.64 microg/m(3), respectively, while at the Arjantin square it was measured to be 34.30 and 28.03 microg/m(3). The emission sources of the trace elements were attributed to the adjoining local industries in the west parts of Tehran.
