Potentially toxic elements (PTE) can cause significant damage to the environment and human health in function of their mobility and bioavailability. Given the urgency to remediate polluted soils all over the world, appropriate innovative and sustainable remediation strategies need to be developed, assessed, and promoted.
Before that, a detailed knowledge of PTE bioavailability and bioaccessibility as well as of soil processes affecting the contaminant dynamics in terms of lixiviation, colloidal transport, redox conditions, or microbial activity is essential in order to assess the actual danger/risk posed by contamination. It is widely recognized that bioavailability of toxic elements in soils depends on their solubility and geochemical forms, rather than on their origin and total concentration. Therefore, the knowledge of their spatial distribution and chemical speciation in soil is of paramount importance to perform an accurate risk assessment. Investigating these aspects requires the use of analytical techniques able to solve the high complexity of the soil matrix with a spatial resolution down to the micrometer- or even nanometer-scale.
In addition, a correct evaluation of a remediation intervention requires a detailed knowledge of the geochemical forms into which PTE have been converted following the soil treatment. This information is crucial to predict any possible transformation PTEs might naturally undergo over time or as consequence of physical-chemical perturbations that might impact the soil system.
The aim of this Special Issue is to address all the above reported aspects, i.e., the assessment of PTE contamination in soil systems using innovative approaches, the study of soil processes affecting pollutant dynamics and the application of new sustainable remediation techniques for the long-term reduction of the threat posed by PTE towards the health of the environment.
