        Evaporate basin of North and West of Garmsar, tectonically is an east-west graben that located in thenorth border of central Iran back-arc basin. Garmsar fault as the most important tectonic structure ofthe studied area, trending east-west, is accommodated in north of Garmsar which declines towards thewest and its trend changes to NW-SE. The mentioned fault is a thrust dipping to the north with leftlateral attitude. Considering fracture system of salt structures in the studied area implies on influencingE-W structural trend of Garmsar thrust on salt structures. Garmsar thrust as the principle structure hasthe most important role in upwards movement of upper Eocene-Oligocene salt mass and taking themto the surface. Outcropped evaporate system imply existing a salt nappe aquifer in north of centralIran. Manuscript profile

        AbstractDue to industrial activities, water and soil pollution with heavy metals is one of the most critical threats to natural ecosystems and humans. Due to their non-degradability and bioaccumulation properties in living tissues, these metals are moved in the food chain and cause various diseases when they enter the body of consumers. Therefore, the purpose of this study was to evaluate the health risk of nasal metals, and cadmium is in water and Snapper in Imam Hassan port. In this study, 60 samples of common Snapper from the Imam Hassan port of Bushehr were caught by the net and selected. Findings show that the mean concentrations of lead and cadmium in the muscle tissue of average Snapper are 0.903 0 0.021 and 0.348 0 0.045 mg/kg, respectively. Comparison of the results of this study with the standards of the World Health Organization showed that the average concentration of lead and nickel in the muscle tissue of each fish is higher than the permissible level of the World Health Organization, which can be dangerous to human health. According to the results, these metals in the skin and muscle significantly correlated with weight and length. Still, the amount of lead and cadmium in muscle was not significantly correlated with weight and length. Manuscript profile
