Abstract
Air pollution is categorized among the major issues due to the fluid nature of air. The most important environmental problems in urban and industrial areas that threaten human health are due to the fact that some of these pollutants are the suspended particles in the air leading to dust phenomenon. Qualitative and quantitative evaluation of dust plays an important role in determining the origin of planning to contain and deal with them. For this purpose, due to the possible presence of metals Hg, Pb, and Cd along with dust particles, the analysis of Teflon and fiberglass filters was used in air pollution monitoring stations in the city of Zahedan. The amount of metals was measured by atomic absorption spectrometry after acid digestion. The results of this study showed that the amount of lead, cadmium and mercury measured in both types of air filters (Teflon and fiberglass) are within the limits permitted by international standards, California, EU Target WHO and Federal.
