Industrial activities and high traffic density are the most important heavy metal pollution sources in urban areas. Roadside dust created by atmospheric deposition can be one of the best indicators for heavy metal contamination levels. The present study reports the spatial distribution patterns and degree of heavy metal pollution (Cd, Cr, Ni, Pb, Zn, and As) in 50 roadside dust samples from urb...

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...

Polluted sediments limit the useful and biotic life of a water reservoir. Therefore, classification verification contamination pollution levels reservoirs are essentials for preservation biota to organize actions environmental management. Thus, aim this study is determine concentrations potentially toxic metals [lead (Pb), zinc (Zn), nickel (Ni), copper (Cu), cadmium (Cd)] in sediment samples c...

The Salado River is a lowland river that drains vast and productive region of central Argentina into the Río de la Plata estuary. To evaluate water quality geochemistry major trace metals (Fe, Mn, Zn, Cu, Pb, Cr Ni), sediments samples were collected along 500 km basin (n = 21). Waters highly alkaline (pH: 8.8 ± 0.4), saline (5.2 1.8 mS/cm), turbid (467 237 NTU) eutrophic (chlorophyll a: 187 119...

This study concerns the distribution and potential sources of elevated heavy metal concentrations (Cu, Zn, Pb, Cd, As) in surface sediments of the Dongzhai Harbor, Hainan Island,a national important mangrove ecosystem protection area.It was found that the pollution of As may occur occasional biological effect by numerical Sediment Quality Guidelines. Further, Geoaccumulation indices (Igeo) sugg...

Radiochemical and elemental analysis of clay soils collected from different locations within Ekiti State have been performed in this study using gamma and XRF spectrometric measurements. The results of this study show that the mean concentrations of uranium ranged from 2.2 ± 1.0 mg/kg to 3.2 ± 1.1 mg/kg, that of thorium ranged from 4.0 ± 0.5 mg/kg to 5.7 ± 1.7 mg/kg, while potasium presented in...

Urban ares are subjected to intensive pollution due continuous anthropogenic activity. In order assess the influence of thermal power plants and waste incineration on City Moscow recreational areas, mass fractions 37 major trace elements were determined using instrumental neutron activation analysis in soil samples collected at two different depths vicinity more potential contamination sources....

For the pollution assessment and quantitative source apportionment of heavy metals in surface dust, a total 52 dust samples were collected from bus stops Tianshui City. The geoaccumulation index (Igeo) potential ecological risk (RI) used to analyze levels caused by metals. Positive Matrix Factorization (PMF) receptor modeling geo-statistics employed results as follows. ① Except for Mn, Co V, me...

Exponential industrialization and rapid urbanization have resulted in contamination of soil by metals from anthropogenic sources in Dongguan, China. The aims of this research were to determine the concentration and distribution of various metals (arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), mercury (Hg), nickel (Ni), lead (Pb) and zinc (Zn)) in soils and identify their potential heal...

Previously conducted studies have established that soil contamination by trace elements (TEs) around coal mines affects ecological biodiversity and human health. One of the ways to protect health surrounding population mine sites is through assessment impacts accurate procedures for establishment relevant reclamation plan. The aim study develop an applied methodological approach easily assess q...
