Potentially toxic elements, pollution and hair

2011
Heavy metals (HMs) are potentially toxic elements (PTEs) considered to be among the most dangerous and damaging polluting substances. However, at the trace level, many of these may be necessary to living systems. Exposure to PTEs is a well-known problem in industrialized countries.

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 ...

Role of Potentially Toxic Elements in Soils

2018
There are numerous sources of toxic elements in soils. In naturally occurring soils they can accumulate during weathering of rocks. Background concentrations in soils are thus determined by the concentrations in the underlying parent materials. Most toxic elements in soils exhibit strong adsorption by clays.

Potentially Toxic Elements in Drinking Water in Alphabetical Order

2014
Most toxic elements in drinking water are regulated by WHO and EU. Elevated levels of aluminum in drinking water are suspected to be related to dementia and Alzheimer’s disease; arsenic is linked to skin disorders and lung cancers. Cadmium may cause renal effects.

Potentially toxic elements and rare earth elements in sandy soils from the Brazilian Cerrado

Environmental Monitoring and Assessment, 2021
This study aims to determine the concentration of potentially toxic elements (PTEs) and rare earth elements (REEs) in Brazilian sandy soils under the Cerrado at the Parnaíba-São Francisco Basin transition. We also explored the geochemical correlation between these elements and pH, cation exchange capacity (CEC), total organic carbon (TOC), sand, clay ...

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.

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 ...

Quantification of Selected Toxic and Potentially Toxic Elements in Vegetables, and Health Risk Assessment

2020
Vegetables play an important role in human nutrition and their importance in diet is determined by its chemical composition. Numerous studies indicate a high degree of contamination of soil and plants produced in certain agro-ecological conditions, especially near urban and industrial areas.

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
