Abstract :

Background and objective: High concentration of elements (particularly heavy elements) have been always associated with environmental problems in terms of threats for local animals and plants, making it necessary to determine the concentration of heavy elements when assessing environmental quality. Geogenically high concentration of heavy elements and their spread across protected zones tend to impose irreparable damages to regional environment. Method: In the present research, remote sensing studies based on ETM and ASTER data were undertaken to determine regional alterations and structures, and geochemical studies were performed to determine how and why environmentally heavy elements are spread across Palang-Darreh region and Dali deposit located in Markazi province, with the results finally compiled into an environmental interpretation. Approximately, a total of 471 samples were processed، of which 62 samples were taken from Palang-Darreh area. The samples taken from Palang-Darreh area were analyzed via ICP and ICP-OES methods. Findings: Once finished with processing and statistically analyzing the chemical data، elemental anomaly diagrams and maps were prepared and, finally, statistical populations were investigated with respect to the international criteria set by WHO (World Health Organization). Discussion and Conclusion: It was indicated that, high concentration of some elements across the area was of geogenic nature. Since this location is a protected area and Dali mine is situated here, so survey of medical geology studies and proper solutions were presented to lower human and environmental of locations.
