Heavy metal concentration of soils affected by Zn-smelter activities in the Qeshm Island, Iran
Authors
Abstract:
In this study, concentrations of heavy metals in soils around a Zn-smelter in Qeshm island, Iran, are investigated. Calculated geoaccumulation index (Igeo), contamination factor (Cf), and contamination degree (Cdeg) values indicate surface soil contamination by toxic metals (As, Cd, Pb, and Zn). The results also indicate that most contaminated areas are located in the vicinity of the smelter and waste pile. However, concentrations of soil metals decrease with increasing distance from the pollution sources. Results from a potential ecological risk assessment indicate high risk in areas around the smelter. Statistical analysis also confirms the role of the Zn-smelter in soil contamination in the study area.

Fuel storage tanks are one of the main sources of water pollution as well as loss of crude oil and oil products in refineries. In the process of utilization of these tanks, considerable amounts of hydrocarbons may find their way into the coastal water, which eventually lead to loss of valuable hydrocarbons. Oil type, climatic condition and characteristics of oil tanks are among the main variab...
