Spatial Evaluation of Environmental and Geomedical Effects of Heavy Metals in Davijan 1:50000 Sheet based on Single-Variable Statistical Tests

Metals enter the life cycle of plants and organisms through water and soil, causing short-term and long-term effects which can endanger theirbio-system. As heavy metals do not play a significant role in the biological and organic compounds of human body (and the majority of other plant and animal species), they would gradually be accumulated in specific areas in the body, ultimately leading to poisoning as well as physical and sychological disorders(Humans). Davijan Area is located in the southeast of Malayer 1:100000 Geological Sheet. Through conducting field, laboratory, and library studies in the vicinity of thissheet, as well as taking geochemical samples providing 2D and 3D maps of the area, we discovered that concentrations of certain elementslike arsenic, nickel, and lead, in certain areas such as Lasavand Village,Zanganeh Paeen, Mishen and Aznavole were greater than themaximum standard limits recommended by international Organizations and institutions. This can be a significant reason for the highdocumented cancer statistics in the area. Therefore recommend that a more detailed investigation into the matter be conducted in the future works.
