Abstract The paper presents the results of research into toxic metal concentrations in surface layer bottom sediments Lake Gopło. objectives were to identify levels and spatial variability Cu, Pb, Cd, Zn, Ni, Cr, As Hg concentrations, their potential sources determinants pollution levels. Metal contamination was assessed using geoaccumulation index (Igeo), load (PLI) ecological risk (RI). Chemo...
Heavy metal(loid)s (HMs) contamination in agricultural soil and crops is related to the quality safety of products public health has attracted worldwide attention. This study systematically investigated bioaccumulation HMs including Cd, Pb, Cr, Hg, As Se associated (Tea, Plum Corn) Guizhou Province, China, assessed risks edible part using bioconcentration factor (BCF), geoaccumulation index (Ig...
Water and sediment samples were collected from six different stations, located along the Nil River between February and June 2015. Concentrations of cadmium, lead, zinc, and copper were determined. The extent of the sediment pollution was assessed, using the multiple pollution indices, namely contamination factor (CF), pollution load index (PLI), and the geoaccumulation index (Igeo). The result...
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...
Background and Objective: Today, soil and water pollution with heavy metals is one of the major challenges around the world. The aim of this study is to investigate the contamination of soils around a lead and zinc mine. Materials and Methods: In the summer of 2019, 100 soil samples were taken from the mine vicinity and the characteristics of texture, acidity, salinity, calcium carbonate, orga...
Since oil is the primary source of vanadium in environment and crude has a correspondingly high percentage vanadium. Vanadium crucial as sign contamination. Twenty soil samples were taken from various locations surrounding East Baghdad field Iraq during February 2022 then analyzed to determine effects industrialization along with urbanization-related pollutants. The using spectrophotometry anal...
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 ...
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 Chah-Shaljami polymetal ore deposit contains heavy metal anomalies in various mineralization zones. Geochemical distribution and correlation of elements in surficial soilsindicate that sulfide, sulfate, sulfosalt and silicate mineral occurrences (e.g. Pyrite, chalcopyrite, galena, sphalerite, molybdenite, enargite, hornblend and biotite) in mineralization and stockwork zones resulted in the...
water and sediment samples were collected from six different stations, located along the nil river between february and june 2015. concentrations of cadmium, lead, zinc, and copper were determined. the extent of the sediment pollution was assessed, using the multiple pollution indices, namely contamination factor (cf), pollution load index (pli), and the geoaccumulation index (igeo). the result...
