Abstract The Akaki River and its tributaries, in the city of Addis Ababa, are polluted by potentially toxic elements (PTEs) (Sb, Zn, Cd, As, Hg, Cu, Pb, Fe, V, Ni, Co, Mn, Cr, B, Sr Ba) varying degrees due to significantly fast urban expansion industrial activities. water samples collected from twenty-six different locations or sampling sites along some tributaries were analyzed ICP-MS determin...

In the last decade, extensive studies have been conducted to quantify influence of different factors on potentially toxic elements (PTE) bioaccessibility in soil; one most important is soil size fraction. However, there no agreement about fraction and methods investigate bioaccessibility, as very few review articles are available PTE none addressed particle bioaccessibility. This study provides...

Background: Cereals are the most staple foods in human diet and the main components of the daily diet. This work was designed to determine the level of essential and non-essential elements, the in vitro bioavailability, interrelationship, and associated health risk in consumed cereal grains in Nigeria to assess their safety and wholesomeness. Methods: The contents of phytate, oxalate, and some...

sediments are generally regarded as the sink for dissolved elements carried out to the sea by rivers. in order to study the source and mechanism of metal transport in sea water, 123 surface sediment samples were taken by using grab sampler in the northwest part of the persian gulf in summer. grain size analysis and geochemical analysis by icp-oes were carried out on samples after sample prepara...

In this study, the sequential extraction method was applied to extract selected potentially toxic elements (PTEs) (Cd, Cr, Cu, Fe, Ni, Pb and Zn) in river sediments collected from Blood River situated Seshego area, Limpopo Province, South Africa. The study aimed assess a possible trend of mobilisation these sediment water. accuracy confirmed by analysing sediment-certified reference material, q...

The aim of this research was to determine the Cu, Ni, Zn, Cd, and Pb contents in following wild plants: dandelion (Taraxacum officinale Web.), broad-leaved plantain (Plantago major L.), ribwort lanceolata L.) collected from natural environment at three different locations north Republic Srpska, surroundings Banja Luka (two localities) Doboj (one locality). examined species represent edible medi...
