This work contributes to the monitoring of heavy metal pollution Agricultural soils, Katsina State Nigeria, using Atomic Absorption Spectrophotometry. The contamination soil samples were analyzed based on Geoaccumulation index (Igeo), enrichment factor (EF), (CF), load (PLI) and potential ecological risk (PERI). health risks evaluated metals estimated Hazard Quotient (HQ) Index (HI)) evaluate p...

Heavy metal pollution significantly reduces the quality of environment and threatens human health, especially in industrial cities. This study investigated toxic metals concentrations, levels health risks assessment urban soils Yazd City, as an city center Iran. Soil surface samples (0–10 cm) were collected from 30 points area for geochemical analysis. The concentrations heavy determined using ...

Oil spillage is one of the common pollution events global water-soil ecosystems. A comprehensive investigation on heavy metals surface water and sediments was conducted after oil spill incident in Sela River its tributaries Sundarbans mangrove forest ecosystems, Bangladesh. Water sediment samples were collected from preselected sampling points River, elemental (Pb, Cd, Cr, Co, Cu, Ni, Fe, As, H...

Xi’an-Baoji Highway is one of the oldest and most important highways in northwest China. In this study, the concentrations (0-20 cm) of Pb, Zn, Cu and Cr at 5-1000 m distances in the roadside soils along Xi’an-Baoji Highway were experimentally determined to analyze their spatial distribution and evaluate their contamination levels. The spatial distribution (mg·kg) of Pb, Zn, Cu and Cr at 5-1000...

Concentrations of seven heavy metals (Cd, Cr, Cu, Hg, Ni, Pb, and Zn) and one metalloid (As) as well as various parameters (pH, organic carbon, granulometric analysis and cation exchange capacity) were analyzed in 77 soil samples collected in the mining areas of La Zanja and Colquirrumi (Department of Cajamarca) and Julcani (Department of Huancavelica). Our study proposed geochemical baseline v...

To accurately understand soil environmental quality and improve the problem of traditional method, which is that it has a single evaluation factor cannot reflect overall condition soil, complex geological heavy metal modeling method based on Nemerow index proposed. Index methods, ArcGIS technology, human health risk assessment were carried out to obtain spatial distribution metals in current st...
