The contamination levels and distribution of heavy metals were assessed in riverbed sediments water column samples from Mura Kimpulande Rivers, both impacted by copper-cobalt gold mining activities. Analyses performed using inductively coupled plasma-mass spectrometry (ICP-MS), atomic absorption (AAS), fluorescence (AFS). Results showed high concentrations Ni, Cu, Zn, As, Cd, Hg samples. rivers...

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...

The concentration and distribution of trace metals were determined in sediment cores from the Khuan Khi Sian wetland, Thailand. collected seven stations dry wet seasons 2022. Pb, As, Cd season range 0.00–60.16, 0.00–6.68, 0.00–0.92 mg/kg (dry weight), respectively. Meanwhile, 0.00–12.12, 0.00–3.86, vertical profiles metal concentrations core show a general increase bottom to top. Average heavy ...

Abstract Background The concentration of heavy metals and their spatial distribution in surface sediments collected from the Thondi coast, Palk Bay, South India were analysed this study. sediment grain size, pH, EC, major elements (Fe, Al), metal concentrations (Mn, Cr, Zn, Cd, Ni, Cu, Pb) determined values for geoaccumulation index ( I geo ), enrichment factor (EF), potential contamination C p...

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...

Coal mining is inevitable for economic growth of a country, but at the same time deteriorates the quality of the environment. Open cast mine, especially affects the top soil most negatively. In the present study, soil samples from three representative areas of mining viz proposed, operational and abandoned sites from Charhi and Kuju of Jharkhand were collected and analysed for physicochemical p...

Total metals concentrations, Geoaccumulation index (Igeo), Pollution load index (PLI), degree of contamination (DC) and sediment quality guidelines (SQGs) were used to assess heavy metals contamination status and ecological risk in the sediments from the Libyan Mediterranean coast. The distribution pattern of heavy metals in the sediment follows the sequence: Fe>Pb>Mn>Ni>Zn>Cr>Cu>Co>Cd. Over th...

There is currently a wide variety of methods used to evaluate soil contamination. We present a discussion of the advantages and limitations of different soil contamination assessment methods. In this study, we analyzed seven trace elements (As, Cd, Cr, Cu, Hg, Pb, and Zn) that are indicators of soil contamination in Dexing, a city in China that is famous for its vast nonferrous mineral resource...
