Coastal aquatic ecosystems are environments increasingly affected by human activities due to urban discharges and their use as dumps. The objective of this study is determine the profiles metallic elements concentration (Al, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Cd, Pb) Cotonou channel sediments evaluate quality. For this, surface (0-5cm) were sampled at 13 sites along channel. Thus,Geoaccumulation I...

This study aimed to investigate the risk of element/heavy metal pollution caused by listvenitization. In this context, heavy listvenite-derived soils in region where listvenitized ultrabasic rocks are present as a result hydrothermal alterations vicinity Alakeçi (Bayramiç Çanakkale/Western Türkiye) was investigated with index, geoaccumulation index and integrated parameters. For purpose, Cu, Zn...

in this study, the concentrations of heavy metals (ca, zn, cu, fe, mn, ni) in thesediment of shavoor river in khuzestan province in iran has been investigated. after the library studies and field studies, six samples of water and sediment were taken from the river in order to evaluate heavy metal pollution in sediments. to determine the geochemical phases of metals in sediment samples the 5-ste...

Soils are the basic and most important resources of any people. Differences in soil’s physical and chemical properties are related to the spatial distribution of land uses. Most of these human activities generate toxic substances that are transported considerable distances away from source and become accumulated in soils, sediment, water bodies and fisheries. Urban soils are largely affected by...

The Al-Salam Lagoon is one of the recreational sites along Jeddah coast, showing environmental impacts urbanization coast. A sediment core (220 cm) was collected from intertidal zone to evaluate heavy metals (Fe, Mn, Cr, Ni, Cu, Zn, and Pb) geochemical indices (contamination factor, geo-accumulation index, pollution load index). In organ-ic-rich muddy sediments (0–100 cm), there a high content ...

A three-year study, designed to record the level of potentially toxic elements within urban complex in city Volos, Greece, was carried out between 2018 and 2020. For needs aforementioned 62 surface (0–15 cm) soil samples were collected each year (i.e., 186 total) from an area 3.65 km2, average value pseudo-total metal concentration measured. Soil pollution indices, such as contamination factor ...

the inter-tidal mangrove environment of mengkabong lagoon is important as it supports the local fishing activities, nursery grounds for many fish and shellfish species, and as well as being central for ecotourism activities. the study showed that in general, the physicochemical parameters (ph, salinity and electrical conductivity), granulometric fractions, organic matter, base cations (na, k, c...
