Potentially toxic elements in iron mine tailings: Effects of reducing soil pH on available concentrations of toxic elements

Environmental Research, 2022
Tailings from iron mining are characterized by high concentrations of iron and manganese oxides, as well as high pH values. With these characteristics, most of the potentially toxic elements (PTE) contained in the tailings are somewhat unavailable. The aim of the present study was to evaluate how a reduction in the pH of iron mine tailings may affect ...

Arthropods in landfills and their accumulation potential for toxic elements: A review

Environmental Research
Landfills, as a source of potentially toxic elements (PTEs), pose a threat to the environment and human health. A literature review was conducted to explore the diversity of arthropods inhabiting solid waste landfills, as well as on the bioaccumulation of PTEs by arthropods. This review presents scientific papers over the last 20 years. Their importance

Critical tissue concentrations of potentially toxic elements

Plant and Soil, 1985
Tissue concentrations of young plants, or of young leaves, of crop plants or species used as test plants offer some promise as simple and approximate indicators of toxic levels of elemental pollution of the soil environment.

Investigation of potentially toxic elements in urban sediments in Belgrade, Serbia

Journal of Environmental Science and Health, Part A, 2020
Concentrations of 10 potentially toxic trace elements were measured in soil samples collected from 18 sites in urban areas of Belgrade, the capital and the largest city in Serbia. Samples were analysed in order to assess the extent of soil contamination and to distinguish natural and anthropogenic input.

Remediation of Potentially Toxic Elements in Contaminated Soils

2014
This chapter aims to offer an overview of the main remediation methods of potentially toxic elements in contaminated soils, mainly heavy metals, metalloids and radionuclides, focusing on their essential characteristics, advantages and limitations. It consists of two main groups of technologies: the first group dealing with containment and confinement ...

Lability of potentially toxic elements in soils affected by smelting activities

Chemosphere, 2013
Determination of total concentration of potentially toxic elements (PTEs) in soil is not a reliable tool for evaluating potential exposure risk for humans. PTE lability (EDTA, SBET and solution extraction) and chemical speciation (BCR sequential extraction) were investigated for Pb, Cd, Cu, and Zn, as well as how these could be affected by flooding in ...

Biomonitoring potentially toxic elements in freshwater ecosystems

2021
Monitoring of water ecosystems, especially rivers, represents an exceptionally complex task, due to the fluctuating discharges and continuous water movements, with the consequent need to consider either the temporal dynamics in the parameters analysed or time-integrated measures.

BIOACCESSIBILITY STUDIES OF POTENTIALLY TOXIC ELEMENTS IN DUST FROM OFFICES

BIMA JOURNAL OF SCIENCE AND TECHNOLOGY GOMBE
Potentially toxic elements are commonly referred to as heavy metals which are toxic and cannot be broken down. Potentially toxic elements are known to have a negative impact on human health especially children through oral ingestion, dermal and inhalation. In this study, the total metal concentration was determined in dust samples from selected offices
