Journal of Soils and Sediments, 2014
This study investigated the behavior of cadmium (Cd), lead (Pb), nickel (Ni), and zinc (Zn) in urban sediments collected in commercial, residential, and industrial areas of the city of Porto Alegre, Brazil, and evaluated different degrees of pollution in this urban subdrainage basin through the use of the geoaccumulation index (Igeo). Concentrations of

Heavy metal pollution in orchard soils is of increasing concern owing to the potential health risk via the food chain. The evaluations of the degree of heavy metal contamination and the potential sources in soils from navel orange orchards in the Ganzhou district were investigated in the present study with the geoaccumulation index and hierarchical ...

An assessment of marine pollution due to metals was made in the Suez Gulf based on surface costal sediment collected from 18 locations along the Gulf. The samples were dried and acid-digested, and the metal contents (Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, and Zn) were determined using a flame atomic absorption spectrophotometer (air–acetylene) with deuterium ...

A study on the characterization of sediment quality was conducted along a stretch of the Benin River, Niger Delta, Nigeria, between June and December, 2011 to evaluate the impact of anthropogenic activities. Five stations were selected from Ajimele to Koko for the investigation. Samples were analysed using standard methods.

Although the Igeo is widely used in heavy metal contamination studies, its application differs in each study in terms of the mathematical equation used, the chosen background, and whether the fine fraction or whole sediment matrix is used. This study aims to assess these different methods, propose a new equation to calculate this index and use the ...

In this paper, the contamination degree of the Rybnik Reservoir with cadmium, copper and nickel was analyzed. Quality of the water from the reservoir was determined by drawing comparisons between the metal content in the water and both the officially permitted levels (contamination factor) and levels of metals occurring in the water of non-contaminated

The Meme River in Lokoja is a tributary of the River Niger and a place where household discharge their domestic and industrial refuse. This however makes the river to be highly polluted due to these discharges. This necessitates the present study to assess the level of heavy metals contamination in the coastal sediment of Meme River in Lokoja using ...
