Stable Zn isotopes are increasingly used to trace the source of metal pollution in the
environment and to gain a better understanding of the biogeochemical cycle of Zn. In this
work, we investigated the effect of plants on Zn isotope fractionation in the soil–plant system
of the surface horizon of two Zn-rich Technosols (pH 6.73–7.51, total Zn concentration=
9470–56600 mg kg–1). In a column experiment, the presence of Agrostis capillaris L.
significantly increased the mobilization of Zn from soil to leachate, predominantly as a result …
