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...

Sediments represent a critical compartment of marine coastal ecosystems due to the toxic and long-lasting effects contaminants buried therein. Here, we investigated properties surficial sediments in front Southern Marche Region coast (Central Adriatic Sea, Italy). The grain size was determined by X-ray sedigraphy. TN OC contents were elemental analysis. concentrations Al, Fe, Mg, K, S, Ca, Ti, ...

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...

This study presents an overview about the arsenic (As) contamination and its sources in two European countries. Arsenic is a highly toxic element inorganic form it carcinogenic to human seven low concentrations. The occurrence of As surface water, stream marine waters, groundwater, bottled sediment, soil, mines, seafood, environmental origin, impacts on health are discussed. classes Geoaccumula...

The aim of the study was to assess quality agricultural soils, which accumulate additional amounts heavy metals from fertilization and modify their bioavailability, with use interdependencies between biological chemical properties conditioned by distance communication routes. Our results indicated that had an impact on enzyme activity in soils accumulation significantly related edge road, locat...

In tropical and subtropical latitudes, woody plants known as mangroves flourish in slimy, anaerobic soils on the boundary between land sea. They can withstand extreme weather conditions like high temperatures, unreliable tides, strong winds, salt. The objective of this study was to determine concentration nine trace elements (Hf, Ga, Ba, V, Cs, Sc, Sb, Ta, Co) sediment mangrove forest along wes...

The concentrations of eight heavy metals (Cu, Zn, Pb, Cd, Cr, Ni, Hg, and As) in the intertidal surface sediments from Quanzhou Bay were determined to evaluate their levels and spatial distribution due to urbanization and economic development of Quanzhou region, southeast China. The ranges of the measured concentrations in the sediments are as follows: 24.8-119.7 mg/kg for Cu, 105.5-241.9 mg/kg...

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...
