Risk assessment of soils polluted by potentially toxic trace elements generally is a complex
procedure that includes many variables and parameters, many of them difficult to assess …

Trace metals occur naturally in rocks and soils, but increasingly higher quantities of metals
are being released into the environment by anthropogenic activities. Metals are chemically …

Purpose The determination of the contribution of background values in a potentially polluted
soil is very important in defining the contamination extension, in particular in areas of …

The aim of this survey was to assess the concentration range of potentially toxic elements
(PTE) in agricultural soils of the Lombardia plain and to consider their spatial variability …

During the last three decades, the scientific community, politicians and decision makers
have focussed on the behaviours of trace elements in soil, its accumulation and toxicity, the …

Concern about health effect of Potentially Toxic Elements (PTEs) has led to an increasing
global attention about their concentration levels in the environment. Soil geochemistry has …

Harmful effects of potentially toxic elements (PTE's) in soils relate to their geochemically
reactive fraction. To assess the degree of the reactivity, specific extractions or models are …

A soil geochemical survey was undertaken in the cultivated region of Agia in Thessaly area,
Central Greece. The objectives of the study were to assess the levels of soil contamination in …

Geochemical background concentrations of potentially harmful elements and species
(PHES) may have a high spatial variability and their natural levels can be higher than those …

A brief review on the occurrence of high natural concentrations of potentially toxic elements
(PHEs) in soils and water is presented, analysing also various approaches and strategies …
