Cr, Co, Cu, Zn, Cd and Pb in the bottom sediments from 93 sites at Quiberon bay were analyzed by Inductively Coupled Plasma Mass Spectrometry (ICPMS) after acid extraction. The ranges of the concentration in the sediments are as follows: 27.3 μg/g (Cr), 11.6 μg/g (Co), 13.8 μg/g (Cu), 42.0 μg/g (Zn), 0.08 μg/g (Cd) and 17.8 μg/g (Pb). Potential contamination of the bay was assessed by Igeo and ...

Background: Evaluation of heavy metals as toxic pollutants in environment has a significant importance in environmental pollution studies. surficial sediments of water resources have a high potential in releasing heavy metals to the upper water environment, hence sediment analysis presents guidelines to the authorities for monitoring the environmental systems. Methods: In this study, total an...

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...

The Salado River is a lowland river that drains vast and productive region of central Argentina into the Río de la Plata estuary. To evaluate water quality geochemistry major trace metals (Fe, Mn, Zn, Cu, Pb, Cr Ni), sediments samples were collected along 500 km basin (n = 21). Waters highly alkaline (pH: 8.8 ± 0.4), saline (5.2 1.8 mS/cm), turbid (467 237 NTU) eutrophic (chlorophyll a: 187 119...

Kawasan muara merupakan salah satu ekosistem perairan yang sering mengalami kontaminasi logam berat seperti nikel (Ni), cadmium (Cd), timbal (Pb), dan merkuri (Hg). Kontaminasi tersebut biasanya berasal dari aktivitas manusia kegiatan rumah tangga, perkapalan, industri. Salah wilayah terletak di sekitar kawasan adalah laut Pulau Pasaran. ini terkenal sebagai sentra pembuatan ikan asin Provinsi ...

 Study Design: were randomly within industries communities vicinity (SMRI) analyzed XRF.
 Place Duration Study: was carried out Ogijo Sagamu Local Government Area, State, located Southwestern Ni...

In the present paper, an investigation on natural and anthropic radioactivity heavy metals content in a basalt aggregate for concrete from Sicily, Southern Italy, was performed as case study. particular, evaluation of specific activity radium-226, thorium-232, potassium-40 caesium-137 radionuclides by using High-Purity Germanium (HPGe) γ-ray spectrometry, together with estimation several indexe...

Dynamically developing urbanization causes a number of environmental effects, including those related to the chemical transformation soils. Relatively less information about urban areas Arctic and Subarctic zones, constructed mostly on permafrost intensively populated can be found. By example analysis basic soil properties concentrations trace metals in soils cities Salekhard, Urengoy, Nadym, N...

The accumulation of tailings from gold mining and smelting may result in PTE pollution. We investigated contamination a large amalgamated mine pond Pinggu County, Beijing. In November 2017, 30 soil samples were collected around the pond. concentrations pollution degree PTEs sources Sb, As, Cd, Cu, Pb, Zn Hg analyzed. average concentration these elements near (16.24, 28.29, 0.99, 171.04, 263.25,...
