This study presents trace elements levels in surface and deep sediments of the Toulon bay (SE France) subjected to anthropogenic inputs (navy base, harbors, etc.). The studied elements (As, Cd, Cr, Cu, Hg, Ni, Pb, Zn) are defined as priority contaminants in aquatic systems. Fifty-five points scattered on the entire bay were sampled, allowing the determination of contaminants distribution with a...

Introduction: This study aimed to assess a good protocol for the contamination indexes, concentration, spatial analysis, and source identification of toxic metals in top soils. Materials and Methods: In the first step, samples were taken from top soil (30 cm) and the metals were extracted and detected with ICP-AES. In the second step, Enrichment Factor, Geoaccumulation Index, and Contamination...

The present research was carried out to examine the health and environmental impacts associated with coal mining activities in Makarwal area Pakistan. To achieve objectives, 41 soil samples were collected from coalmine-affected areas analyzed for major toxic trace elements (TTEs) using atomic absorption spectroscopy. Most of have extremely high concentrations metals such as Ni, Cd, Cr, Cu, Zn, ...

This study collected agricultural surface soil samples from 200 sites in the district of Braničevo, located Carpathian Mountains – Pannonian Basin south Danube River (Serbia). The main objective was to determine contamination by ten potentially toxic elements (As, B, Cd, Cr, Cu, Mn, Mo, Ni, Pb, Zn) and evaluate associated ecological risk via different indices. physicochemical parameters, pH, or...

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...

Introduction. Urban runoff sediments contain heavy metals that generate risk to the environment. Several assessment indexes for have been developed, which show level of contamination particles in environment and their origin. Besides, sediment is also associated with particle size distribution hydrometeorological characteristics. Objective. This work seeks evaluate from collected an experimenta...

The Kolleru Lake is a famous Ramsar wetland of international significance. In this study heavy metal contents in water and sediment samples are reported. It is found that certain potentially toxic metal ions like chromium (4.5-80 µg/L), copper (1-20 µg/L), manganese (1-313 µg/L) and zinc (1.2-57 µg/L) are present in variable quantities in the lake water. When normalized with respect to concentr...
