T1 - Phytoscreening with tree cores N2 - The sampling of plants represents an economical semi-quantitative non-invasive method that complements conventional methods of investigating pollutants in groundwater and soil (leachate). The fundamental principle thereby is that the dissolved contaminants are absorbed through water by the roots. Inside the plant the substances move upwards with the sap current into the trunk or stem and then into the leaves. Using an increment borer, tree cores can then be taken from the trunks of trees and analysed in the laboratory for pollutants. The measured contents can then provide us with insights into the subsurface contamination of a particular site. The scientific literature refers to this semi-quantitative procedure as “phytoscreening” (Sorek et eil., 2008). The suitability of phytoscreening for investigation or monitoring purposes could already be undoubtedly proven for some pollutants, particularly those in the group of chlorinated solvents. The main focus of this document is therefore on those.
