The main purpose of the research was to analyze distribution Arsenic (As), Cadmium (Cd), Copper (Cu), Iron (Fe), Nickel (Ni), Cobalt (Co), Mangan (Mn), and Zinc (Zn) in soft tissues, shells, associated surface sediments Cerithidea obtusa (C. obtusa) mangrove snails collected from Sungai Besar Sepang. concentration iron (Fe) found be highest relation other toxic elements sediments, shells C. obt...

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,...

The goal of this research is to assess hazardous heavy metal levels in PM2.5 fractioned road dust order quantify the risk inhalation and potential health effects. To accomplish this, Inductively Coupled Plasma Mass Spectroscopy (ICP-MS) was used determine concentrations eight metals (Cr, Cu, Ni, Zn, Cd, As, Pb, Hg) portion samples from five different land use areas (commercial, residential, ind...

The Chah-Shaljami polymetal ore deposit contains heavy metal anomalies in various mineralization zones. Geochemical distribution and correlation of elements in surficial soilsindicate that sulfide, sulfate, sulfosalt and silicate mineral occurrences (e.g. Pyrite, chalcopyrite, galena, sphalerite, molybdenite, enargite, hornblend and biotite) in mineralization and stockwork zones resulted in the...

The concentration of heavy metals (HMs) in soil-plant systems was an important indicator soil metal pollution, and the migration transportation abilities HMs from to plants were great significance for evaluating food safety reducing health risks. This study conducted investigate contamination translocation soil-Paeonia lactiflora system Bozhou, Anhui Province, China. pollution assessed by calcu...

the contents of as, cd, cu and mo were determined in soil surrounding meyduk tailings dam based on 21 surface soil samples. assessment of toxic element pollution in studied soil samples needs knowledge of pre-anthropogenic metal concentration to act as a reference against which measured values could be compared. estimating the background values was executed by sampling rocks adjacent to soil sa...

Soil samples in Moryayla village located 156 km northeast of Erzurum and Cu mineralization area around it were collected randomly. In these samples, 20 taken order to investigate the metals found pollution limits sources that cause this pollution. The geochemical analyzes (Cd, Cr, Cu, Ni, Pb, Zn Fe) soil made evaluated with parameters. calculation parameters, enrichment factor (EF); geoaccumula...

Water and sediment samples were collected from six different stations, located along the Nil River between February and June 2015. Concentrations of cadmium, lead, zinc, and copper were determined. The extent of the sediment pollution was assessed, using the multiple pollution indices, namely contamination factor (CF), pollution load index (PLI), and the geoaccumulation index (Igeo). The result...
