Vertical Transport of Heavy Metals in the Soil at a Field Test Site
Abstract
The transport of zinc and copper in soil during a long-term phytoremediation test site was assessed by sampling, analysis and numerical modelling. Initially heavy metal contamination had been applied at different concentration levels using three replicates, and soil properties and vertical heavy metal concentration distribution were measured after 4 years. The results of this study show the change in the vertical distribution of zinc and copper after the following period of ten years. The vertical transport was interpreted considering recharge, evapotranspiration, sorption, plant uptake and outflux. Numerical modelling with Hydrus-1D was applied especially for the zinc movement. It illustrated the vertical movement downwards and the relative importance of the processes involved and the impact of the planned remediation strategy.
