Abstract

Concentration of elements in atmospheric particulate of urban areas has been determined by employing a Ge(Li) detector. In the first part of this study, a single area was selected and samples were collected on millipor filter during three seasons of the year and their results were compared. These results were also compared with the concentration of the same elements reported for other cities. We have concluded that in a dry climate at least two parameters are involved in seasonal changes of trace elements in the atmosphere. They are the rate of wet deposition and reduction of vertical diffusion of airborne particulates.
