One of the sources of dust contaminated with heavy metals, landfill sites, which can cause a lot of environmental problems. The aim of this study was to investigate the contamination of deposited dust binding heavy metals cadmium, lead and zinc in the prevailing wind direction(North West – South East) Khash city's landfill .First, by observing the status of the current landfill deals and Dust samples of 10 stations in the study area was prepared in January 2013. After preparation of the samples, the concentrations of heavy metals using atomic absorption were measured. The average concentration of cadmium, lead and zinc, respectively, 3.28, 83.1, 1190.65 mg/kg was achieved. Igeo zinc, cadmium and lead, 2.76, 2.69 and 1.22 respectively, CF,12.53, 10.94,4.15 respectively and significant ecological risk level was measured. Based on there sults of heavy metals in the dust landfills it is was higher than the standard. The results of data analysis and estimate that 1 almost no pollution controlstations and other stations strong have pollution of heavy metals.
