Dynamically developing urbanization causes a number of environmental effects, including those related to the chemical transformation soils. Relatively less information about urban areas Arctic and Subarctic zones, constructed mostly on permafrost intensively populated can be found. By example analysis basic soil properties concentrations trace metals in soils cities Salekhard, Urengoy, Nadym, N...

Heavy metals are naturally occurring elements, but they regarded as significant environmental pollutants due to their high density and toxicity even at low concentrations. The aim of this paper is the evaluation pollution level heavy in river riverbank sediments, well estimation origin spatial differences along course Vrbas River through Banja Luka. concentrations have been assessed using Induc...

In order to assess the distribution of mercury along the Tarut coast, Arabian Gulf, Thirty eight (38) sediment samples, twenty six (26) seawater samples, and forty (40) Mollusca specimens were collected from the Tarut coast. The concentrations of Mercury in the sediments of the studied area (average 1⁄4 0.55 mg/g) are generally high comparing to the reported values from the Gulf of Oman, Red Se...

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...

To better understand heavy metal pollution and the potential ecological risk of mangrove sediments in Nanliu River estuary, speciation distribution characteristics metals Fe, Mn, Zn, Co, Ni, Cd, Cr, Cu, Pb 13 surface study area were determined analyzed using a modified four-step BCR extraction method, was assessed Geo-accumulation Index (Igeo), Potential Ecological Risk (RI), Assessment Code (R...

In order to investigate concentrations, variability, sources, and human health risk of trace elements, 38 atmospheric dust samples were collected around Arak industrial area. The average concentrations Cd~Zn, As, Pb 3.3, 2.5, 2.4 times higher than the corresponding geochemical background, respectively, while Co, Cu, Ni, Hg lower. Based on geo-accumulation index (Igeo), elements classified betwe...

Abstract This article discussed on the status of heavy metals (As, Cr, Cu, Mn, Ni, Pb and Zn) pollution in coastal sediment cores assess quality from Usukan Beach, Kota Belud. Several geochemical parameter analyses such as pH, moisture content (MC), organic matter (OM) granulometric size were performed to identify physico-chemical properties sediments that affect assessment metal pollution. Hea...

Agriculture plays an important role in the sustainable development of country. Use chemical fertilizers escalate certain components excess quantity thereby deteriorate productivity and leads to unpredicted outcome. This study makes effort reckon accumulation some selected heavy metals [Lead (Pb), Nickel (Ni) Cadmium(Cd)] related indices [bio concentration factor(BCF) translocation factor (TF)] ...

ABSTRACT This study aims to evaluate potential ecological risks and heavy metal pollution in sewage sludge. For these purposes, domestic sludge samples were collected for a period of one year from wastewater treatment plant Bursa, Turkey analyzed metals. The average content the was wherein decreasing order Zn>Cu>Ni>Cr>Pb>As>Se>Cd. As whole, concentration metals below limit values indicated with...

In the Xining area of Huangshui River, China, concentrations globally alarming toxic heavy metals such as chromium (Cr), arsenic (As), lead (Pb), cadmium (Cd), and zinc (Zn) in surface sediments were measured to determine ecological risks riverine ecosystem. Overall, relatively high. The results indicated that Pb/Zn/Cr lower than 120/250/200 mg·kg−1 which was risk screening value each metal for...
