  Air pollution is a major contributor to chronic respiratory and cardiovascular diseases, resulting in an estimated annual premature death toll of 6.2 to 8.4 million individuals. The objective of this study is to investigate the concentration of potentially toxic elements in dust collected from residential complex in Isfahan during the winter (2022-2023). To ensure comprehensive coverage, 31 residential residential complex were chosen across the entire Isfahan City. Dust samples were collected in triplicate (totaling 93 samples) from from the internal surfaces of the ground or first floor of residential complexes, except for common spaces. The samples were transferred to the laboratory and the concentrations of Lead, Cadmium, Arsenic, Zinc, Cobalt, Nickel, Copper, Chromium, and Vanadium were then measured using an ICP-OES device, model Optima 83. The average concentrations of Arsenic, Cadmium, Nickel, Manganese, Cobalt, Lead, and Vanadium in the collected samples were found to be 5.55, 0.95, 32.6, 241, 3.87, 300, and 30.6 mg/kg, respectively. According to the enrichment factor analysis, the concentrations of Lead and Cadmium were of non-natural and anthropogenic sources in all sampling stations except for West Allameh Amini. A notable positive correlation was observed between the Lead enrichment factor and the traffic index at a 95% confidence level (p-value=0.021, r= 0.369). Similarly, a significant strong positive correlation was found at a 99% confidence level between the ecological risk assessment index and the traffic index (Pvalue=0.00, r= 0. 619). This suggests that traffic has a major impact on the concentration of potentially toxic elements at the sampling stations. Manuscript profile

  Soils from the industrial areas in the south of Bandar Abbas County are susceptible to contamination by the export terminal, metal and non-metallic industries. In this research, the concentrations of selected potentially toxic elements in order to determine the contamination level, source and assessment of ecological risk index, also health risk assessment to determine the quantity of potential carcinogenic and non-carcinogenic risks of the elements in the soil of this area was investigated So that a total of 66 soil samples were collected. The Enrichment Factor (EF) and Ecological Risk Index were calculated to measure the contamination level. Principle component analysis (PCA) was used to determine the sources of heavy metals pollution, and also the health risk assessment was used in three ways: ingestion, inhalation and dermal contact. Results indicated that the average of EF for studied elements decreased in the order of Cu, Cd, Pb, Zn, As, Ni and Cr. The mean value of the ecological risk of Cu and Cd indicates medium and high ecological risk, respectively. The Hazard index for all selected elements through ingestion, inhalation and dermal contact in children is higher than that of adults. The results of EF and PCA indicate that the As, Cd, Cu, Pb and Zn have been affected by anthropogenic sources. As, Cr and Cd were regarded as the priority pollutants and Cancer risks in soils were within tolerable risk to human health. Manuscript profile
