The
dendrotolerance experiments with wick supplied tree test systems may simulate
the dendroremediation in a time-sparing manner.
Driven
by
the transpiration stream of the trees, a slowly pollutant application rate to
the soil-tree-system is guaranteed.
The
experiments only simulate the
dendroremediation effects on the soil-water-solved portion
of the nitroaromatic pollutants.
The simulations do not consider those
pollutant portions, which are extracted by the
trees from nitroaromatic pools reversibly bound to the organic soil matrix or
clay
minerals,
Under
natural soil conditions additional enhancement effects of the dendroremediation
potential are expected through:
-
The
additional phytoextraction force of the tree roots by exsudations of enzymes and organic acids
-
The effects of the
microbial consortiums of the rhizosphere promoted by root exudates
-
The
mycorrhiza action with special importance for the coniferous trees
