Speciation and reactivity of lead and zinc in heavily and poorly contaminated soils: Stable isotope dilution, chemical extraction and model views

Z Ren, Y Sivry, M Tharaud, L Cordier, Y Li, J Dai… - Environmental …, 2017 - Elsevier
Correct characterization of metal speciation and reactivity is a prerequisite for the risk
assessment and remedial activity management of contaminated soil. To better understand
the intrinsic reactivity of Pb and Zn, nine heavily and poorly contaminated soils were
investigated using the combined approaches of chemical extractions, multi-element stable
isotopic dilution (ID) method, and multi-surface modelling. The ID results show that 0.1–38%
of total Pb and 3–45% of total Zn in the studied soils are isotopically exchangeable after a 3 …
