Heavy metal concentration of soils affected by Zn-smelter activities in the Qeshm Island, Iran

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 an...

Copper Speciation Assessment in Aquatic Ecosystem Affected by Historical Mining Activities

Abrud river is an aquatic ecosystem exposed to anthropogenic influences exerted by long-term mining. This study examines the level of copper concentrations by assessing both total copper content and ionic forms in surface waters and sediments. These components were studied in 10 control sites located in a section of river that has been exposed to acidic mine water spills and leaks. The partitio...

Current Status of Trace Metal Pollution in Soils Affected by Industrial Activities

There is a growing public concern over the potential accumulation of heavy metals in soil, owing to rapid industrial development. In an effort to describe the status of the pollutions of soil by industrial activities, relevant data sets reported by many studies were surveyed and reviewed. The results of our analysis indicate that soils were polluted most significantly by metals such as lead, zi...
