Water and sediment samples have been collected from five different stations, located along Djendjen River between February and June, 2016 so that the concentrations of Cd, Ni, Zn, and Cu could be determined. The extent of the sediment pollution has been assessed, using the multiple pollution indices, namely Contamination Factor (CF), Pollution Load Index (PLI), and the geoaccumulation index (Ig...

Soils in the Lower Swansea Valley, (United Kingdom) contain elevated level of metals, enough to cause direct or indirect effects on human health. This study assesses severity soil pollution and bioavailability Cu other metals (Ni, Zn, Co, Pb Cr) soils with various distances from a Ni refinery. We compare concentrations operationally defined fractions (bioavailable, bound Fe/Mn oxide incorporate...

Soil pollution by some heavy metals including: Cr, Mn, Fe, Ni, Cu, Zn, As, Mo, Cd and Pb from northern industrial area of Erbil City was assessed. The contamination indices geoaccumulation (Igeo), factor (CF), enrichment (EF), degree (Cdeg), load index (PLI) element (ECI) were applied to assess soil in North Industrial at three sites (for both surface sub-surface soils). Maximum Fe value 34243....

Kadmium (Cd) merupakan logam berat berbahaya yang dapat mengakibatkan terjadinya pencemaran di perairan. Penelitian ini bertujuan untuk mengetahui kandungan Cd pada matriks air, sedimen, dan ikan nilem (O. hasselti) Sungai Tajum, Banyumas serta tingkat berdasarkan Single Pollution Index (Pi), Contamination Factor (CF), of Geoaccumulation (Igeo), Bioaccumulation (BAF), Estimated Daily Intake (ED...

Grain size and concentrations of heavy metals (arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), mercury (Hg), lead (Pb), and zinc (Zn)) of 148 surface sediments and activities of 210Pb and heavy metal concetrantions of one sediment core from the Pearl River Estuary were analyzed. The surface sediments were dominated by silt and sandy silt. Sediment type controlled the spatial distributio...

Contamination of soils with heavy metals is widespread and poses a long-term risk to ecosystem health. Abandoned and active mining sites contain residues from ore-processing operations that are characterised by high concentrations of heavy metals. The distribution and mobility characteristics of heavy metals (As, Cd, Cu, Pb, and Zn) in paddy soil samples from Kočani Field (Macedonia) using ICP-...

As a primary sink of pollutants, urban soil heavy metal pollution and its influence on residents ecosystems has been becoming one the most important environmental problems. In present study, four indices, Geoaccumulation index (Igeo), improved Nemerow (IMN), degree contamination (mCd), security (CSI), as well potential ecological risk (RI), were used to evaluate individual or integrated for sam...

With the rapid development of economy, heavy metal soil pollution causes ecosystem deterioration and raises serious concerns. Topsoil samples (n = 205) were collected to investigate characteristics, risk levels, sources metals in topsoil eastern Tibet. Heavy contents, such as As, Hg, Pb, Cr, Mn, Mo, Ni, Cu, Zn, Cd, tested, potential analyzed using correlational principal component analysis. The...

Introduction: Uncontrolled and improper landfilling of solid waste increases the concentration of heavy metals in the soil. Therefore, this study aimed to investigate soil contamination with heavy metals in the landfill of municipal and hospital waste in Sabzevar city by compiling a map of the severity of heavy metal pollution in the soil. Materials and Methods: Concentrations of heavy metals ...
