Screening various plant species to act as hyperaccumulators and associated health risks could serve a sustainable solution for the bioremediation heavy metals (HMs). For first time, present study explored phytoremediation potential of native plants, soil enrichment, human with contamination HMs in samples collected from municipal solid-waste open dump site. Soil (n = 18 + 18) dumpsite control s...
In this study, concentrations of heavy metals in soils around a Zn-smelter in Qeshm island, Iran, are investigated. Calculated geoaccumulation index (Igeo), contamination factor (Cf), and contamination degree (Cdeg) values indicate surface soil contamination by toxic metals (As, Cd, Pb, and Zn). The results also indicate that most contaminated areas are located in the vicinity of the smelter an...
This study reports the presence of heavy metals (Cr, Ni, Cu, Cd, Pb) in sediment and water column Köyceğiz Lagoon Estuary System (KLES) (South-West Anatolia). The mean metal concentrations (µg L-1) were found as Cr: 3.72-8.36, Ni: 6.51-9.48, Cu: 1.29-11.88, Cd: ND-0.08, Pb: ND-0.34. samples to be below internationally acceptable limits. (mg kg-1) 1.75-4.25, 5.24-12.69, 0.25-0.51, <0.01, ...
The aim of this study is to determine the anthropogenic effects in lake Gala Thrace Region and make an ecological risk analysis as a result these effects. Based on multi-element analyzes samples collected from by Grab Core method, using ICP-MS, which frequently used calculation sediment pollution studies; Ecological lakes with statistical such Enrichment Factor (EF), Contamination (CF), Geoaccu...
Lake Victoria (L. Victoria) is the largest African tropical and freshwater lake, with one of highest pollution levels, globally. It shared among Uganda, Kenya Tanzania, but it drained only by river Nile, longest in Africa. Though environmental studies have been conducted investigations heavy metals (HMs) contamination sediments from fish landing sites ports on Ugandan portion L. are limited. In...
Analyzing the presence and quantifying trace elements is of paramount importance to understand natural environmental processes monitor degree anthropogenic disturbance mitigate impacts already caused. Here, we aimed establish a baseline profile concentrations in sandy sediments intertidal areas three Amazonian beaches (Brazil). For each beach, were collected from different sectors (south, cente...
Assessment of Heavy Metals Pollution in Water and Sediments of Djendjen River, North Eastern Algeria
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...
زمینه و هدف: هدف از انجام این مطالعه بررسی آلودگی خاک های اطراف معدن منگنز ونارچ قم به فلزات سنگین منگنز ، نیکل ، سرب و مقایسه روش های مولر و کرباسی در تعیین شاخص آلودگی و تعیین سهم طبیعی و انسان ساخت عناصرمذکور درمنطقه مورد مطالعه است. روش بررسی: جهت انجام این مطالعه 3 نمونه به صورت سیستماتیک از عمق 5- 25 سانتی متری خاک برداشت و مخلوط شده و یک نمونه مرکب...

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 ...
