  <dc:description xml:lang="eng">Abstract: Soil contamination by potentially toxic elements (PTEs) poses a persistent environmental challenge
due to their long-term stability and bioaccumulation in the food chain. Effective assessment of
environmental and human health risks associated with PTEs requires a thorough understanding of the
processes governing their transformation and immobilization in soil.
In this study the long-term behavior of Pb, As, Cd, and Cr in soils from a historically contaminated
mining area was analyzed using both individual and integrated soil pollution indices, including the
enrichment factor (EF), geoaccumulation index (Igeo), Nemerow index (NI), Pollution Load Index
(PLI), Environmental Risk Index (ERI), and Potential Ecological Risk Index (PERI). A sequential
extraction procedure was performed to assess the geochemical partitioning and potential mobility of
these elements. In addition, a plant growth experiment was conducted under controlled conditions to
evaluate the transfer of PTEs from soil to plants, their accumulation in plant tissues, and their effects
on plant development. Furthermore, potential impacts on human health were evaluated through
carcinogenic and non-carcinogenic risk assessments that considered multiple exposure pathways. In
addition, chromium speciation was analyzed, taking into account the distinct behavior and impacts of
chromium (III) and chromium (IV).
The results demonstrate that the speciation and transformation of PTEs are critical determinants of
their environmental behavior, bioavailability, and potential ecological and health risks. Moreover,
integrating experimental and field-based studies provides new insights into the mechanisms that
control the environmental fate of PTEs and their interactions within the soil-plant system.</dc:description>
