THE ROLE OF PLANTS AND BACTERIA IN PHYTOREMEDIATION - KINETIC ASPECTS
- 997 Downloads
Phytoremediation is the common name for cleaning techniques for polluted soils, sediments, and wastewaters using plants. It has been shown repeatedly that several types of pollutants, e.g., petroleum products and solvents, are degraded faster in the presence of plants. A couple of processes are known to influence the elimination of pollutants, among them transpiration of water, oxygen transport, biological stimulation in the root zone and plant uptake of chemicals. However, it is frequently unclear whether the plants directly metabolise the pollutants, or whether they only play an indirect role by supporting microbial action.
