Potentially toxic elements in serpentine soils and plants from Tuscany (Central Italy). A proxy for soil remediation

摘要

Serpentine soils have relatively high concentrations of potentially toxic elements (PTEs) (Co, Cr, Cu, Fe, Ni) but generally low amounts of major nutrients. They often bear a distinctive vegetation, with specific tolerance to PIES, and a frequently-used approach to understanding serpentine ecology and related environmental hazard has been the chemical analysis of soils and plants. In this paper we report the results of a study on serpentine soils and serpentinophytes from different outcrops in central Italy.
