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...

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...

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...

Erzurum ili İspir ilçesi Ulutaş köyünde yapılan bu çalışmada, tabanda yer alan metamorfik birimin üzerinde volkanik ve sedimanter kayaçlar diskordanslı bir şekilde almıştır. ilçesinin 20 km kuzeyinde köyü yakın çevresinde Cu - Zn cevherleşmesinin çevre topraklardaki metal birikimlerini, kirliliğini metallerin neden olduğu kirlilik kaynaklarını araştırmak amacıyla toprak örneği alınmıştır. Bu ka...

This study presents trace elements levels in surface and deep sediments of the Toulon bay (SE France) subjected to anthropogenic inputs (navy base, harbors, etc.). The studied elements (As, Cd, Cr, Cu, Hg, Ni, Pb, Zn) are defined as priority contaminants in aquatic systems. Fifty-five points scattered on the entire bay were sampled, allowing the determination of contaminants distribution with a...

The objectives of this study were to investigate the seasonal and spatial variations of heavy metal pollution in the overlying water and surface sediments of the Tiaozi River, a tributary of the Liao River, which is one of the seven major rivers and one of the most heavily-polluted rivers in China. Water and sediment samples were collected over four seasons, analyzed for heavy metals (Pb, Cu, N...

This study evaluated the concentration of toxic elements in soil samples from agricultural fields districts Sachaca, Socabaya, Hunter, Quequeña, Yarabamba, Characato and Tiabaya city Arequipa, Peru. The ecological risk, enrichment factor (EF), geo-accumulation index (Igeo) integrated risk (RI) were estimated, while health was determined with hazard coefficient (HQ) (HI) values. Seven collected ...

Heavy metals in road dust pose a significant threat to human health. This study investigated the concentrations, patterns, and sources of eight hazardous heavy (Cr, Ni, Cu, Zn, As, Cd, Pb, Hg) street Zhengzhou city PR China. Fifty-eight samples were analyzed based on three methods risk assessment, i.e., Geo-Accumulation Index (Igeo), Potential Ecological Risk Assessment (RI), Nemerow Synthetic ...
