Summary |
 |
| The combination of carbon isotopes,
nutrients and heavy metals (tracers) in tree-rings constitutes a new environmental
monitoring tool that can distinguish between natural and anthropogenic accumulation of
metals. The degree of influence on tracer assimilation of the different processes to be
studied can vary along a tree. The investigation should address the tracers in tree
leaves, branches and stems (rings) with vertical position above ground level, as this
variation might have a significant impact on the specification of a dendrochemistry
sampling protocol for monitoring of atmospheric pollutants. |
