TIMBRE Guidline on Tree Coring

01.07.2014 05:00

As public version of the TIMBRE Deliverable D4.2, a Guideline for application of Tree Coring as an initial screening tool for typical pollutants in the subsurface is available.

This guideline is an outcome of the work accomplished in TIMBRE working package 4 - Strategies and technologies for integrated site characterisation and remediation are investigated.  One of the tasks coordinated by DTU was to test the feasibility of vegetation sampling as a screening tool for typical pollutants in the subsurface.  

Previous guidelines of tree coring as bio-indicators for subsurface pollution are available. These guidelines report that tree coring is more or less useful for a variety of volatile organic compounds (VOC) such as BTEX (benzene, toluene, ethylbenzene, xylenes), methyl tert.-butyl ether (MTBE), trimethyl benzene and chlorinated solvents (PCE, TCE, DCE, VC). This new guideline goes beyond the previous guidelines, and the main novelty is that it also includes the application for screening of heavy metals, plus some new examples for BTEX. It is based on field applications at sites polluted with BTEX, chlorinated solvents and/or heavy metals.

The guideline describes the method and the application of it including sampling, chemical analysis and data treatment. Finally a short overview of current literature obtained within the TIMBRE project and by others is given.
