Background and aims: Particles in the Breathing air composting Complex because of the diversity of waste, are Carrying dangerous chemicals compound such as metals. The aim of this study was determine the sources and health risk assessment of metals.
Methods: In order to measuring the particle, frm OMNITM Ambient Air Sampler was used. Sampling in the months of February and March 2016 was performed in Processing, aeration and filtration sites. For analysis of heavy metals and sources determined, ICP1-AES and Enrichment factor were used respectively

Results: In this study the average concentration of PM10 particles in Processing, Refinery and aerated Site were 1291, 3557,143 µg/ m3 respectively. The highest concentrations of metal in PM10 particles of aluminum and iron, 73.07, 44.71 µg/ m3 for refining site was obtained respectively. In this study, the additional cancer risks of metals, in refining, processing and aeration was found respectively and all of the cancer risk was higher than the limit set by the Environmental Protection Agency.

Conclusion: The results of this study show that due to the lack of information in the field of measuring particle concentrations on composting in order to study the effects of pollutants on those exposed, investigations of Monitoring study in different parts of the composting facility is necessary.
