Geochemistry, Zoning and Ecological Risk of Heavy Metals in the Dust in Schools located in West Bandar Abbas Industrial Zone
In this study, the dust of primary schools located around the industrial centers of western Bandar Abbas was analyzed. Samples were analyzed by induced coupled plasma spectroscopy (ICP-MS). Environmental index of lead, zinc, cadmium, arsenic, chromium and nickel were evaluated. The results indicate that the study samples, except for chromium, have moderate to very strong contamination factor compared to other heavy elements, with the highest amount belonging to cadmium and lead. The highest value of ecological risk index belonged to the element cadmium (285) and the lowest value of this index showed the element chromium (3.68). The mean geo accumulation index of cadmium was the lowest and lead was the highest. Concentration of these elements was zoned using geochemical analysis datas. Comparison of how metal change and the similarity of their patterns in school dust samples with the average pattern of industrial centers and geological formations confirms the results
