Assessment of the Risk of Non-Cancerous Diseases under the Exposure of Heavy Element in Urban Areas and Troubleshooting Pollutant Sources (The Case of Zanjan)
Journal Title: Journal of Human Environment and Health Promotion - Year 2017, Vol 2, Issue 3
Abstract
Background: Heavy metals are the main air pollutants in cities. Therefore, assessment of the risk of exposure to these metals through inhalation, ingestion, and dermal contact on inhabitants of contaminated areas of the world is of great importance. Methods: A weekly sampling of air particles smaller than 10 microns was performed in a residential area of Zanjan for two years. Risk assessment in the face of heavy metals from inhalation, ingestion, and dermal contact for were measured for two children and adults. After fingerprinting high-risk metals, the air pollutants of the region were analyzed according to the PMF5 model. Results: The results showed that children at risk assessment (1.40 × 1000) at the highest concentration of manganese. The PMF5 model results of fingerprinting 15 heavy metals showed that predominant pollutants in the region, included lead and zinc industries with 42.3%, suspended soil with 26.4%, industrial activities with 23.5%, and combustion and fuel with 7.8% of contamination. It was also found that 55.5 percent of manganese emission was associated with lead and zinc industries and 22.4 percent were related to suspended soil. Conclusion: Risk assessment showed that children were exposed to non-cancerous diseases due to inhalation of manganese particles.
