Areas polluted by heavy metals in soil may pose a major risk to human health and ecological environment safety. In this study, 89 samples were collected from four potato producing areas (Libo, Chishui, Panxian Weining) Guizhou Province, China, the concentrations of 9 analyzed measured. The aims study was evaluate pollution index some potato-producing Province using geoaccumulation method, load ...

Constructed wetlands are an affordable and reliable green alternative to conventional mechanical systems for treating domestic sewage. This study investigates the potential of 14 tropical wetland plant species removing heavy metals from sewage through bioconcentration factor (BCF), translocation (TF), enrichment (EF), geoaccumulation index (Igeo) using batch mesocosm studies. Plants with BCF &g...

Bogra city is highly susceptible to environmental pollution due to over population, rapid industrialization and urbanization during the last decades. A study was conducted to determine heavy metals (Cu, Zn, Pb, Cr, Cd and Ni) pollution level and physicochemical properties in the soils of Bogra city. The concentrations of heavy metals in 14 soil samples were determined by using an Atomic Absorpt...

Gold mining is now widely acknowledged as one of the significant sources soil pollution in developed countries. In developing countries, and levels contamination have not been thoroughly addressed. Thus, this study was intended to determine source level active closed gold areas. The research paper presents load heavy metals (lead-Pb, chromium-Cr, cadmium-Cd, copper-Cu, arsenic-As, manganese-Mn,...

Background and Objective: Contamination of roadside soils with heavy metals is a serious threat to soil ecosystems and organisms and human health. Therefore, the purpose of this study was to determine the concentration of heavy metals in the roadside soils of the Rasht-Qazvin old road. Materials and Methods: 10 out-of-town sampling sites were selected via the field observation of the entire ar...

Total metals concentrations, Geoaccumulation index (Igeo), Pollution load index (PLI), degree of contamination (DC) and sediment quality guidelines (SQGs) were used to assess heavy metals contamination status and ecological risk in the sediments from the Libyan Mediterranean coast. The distribution pattern of heavy metals in the sediment follows the sequence: Fe>Pb>Mn>Ni>Zn>Cr>Cu>Co>Cd. Over th...

There is currently a wide variety of methods used to evaluate soil contamination. We present a discussion of the advantages and limitations of different soil contamination assessment methods. In this study, we analyzed seven trace elements (As, Cd, Cr, Cu, Hg, Pb, and Zn) that are indicators of soil contamination in Dexing, a city in China that is famous for its vast nonferrous mineral resource...
