Theoretische und praktische Aspekte bei der Behandlung von TNT-Kontaminationen

Description: Das Projekt "Theoretische und praktische Aspekte bei der Behandlung von TNT-Kontaminationen" wird vom Umweltbundesamt gefördert und von BioPlanta GmbH durchgeführt. Phytoremediation has been defined as the use of green plants and their associated micro-organisms, soil amendments and agronomic techniques to remove, contain or render harmless environmental contaminants. Phytoremediation is expected to be complementary to classical bioremediation techniques, based on the use of microorganisms. It should be particularly useful for the extraction of toxic metals from contaminated sites and the treatment of recalcitrant organic pollutants. At the present time, phytoremediation is still a nascent technology that seeks to exploit the metabolic capabilities and growth habits of higher plants: delivering a cheap, soft and safe biological treatment that is applicable to specific contaminated sites and wastewaters in a relatively recent focus. To develop such techniques, in vitro systems often offer advantages over the whole plant, provides that xenobiotic metabolism or metal accumulation in cultivated plant cells and tissues reflect what occurs in vivo. In particular the screening of plant species to degrade or accumulate xenobiotics belonging to the same chemical family will be done much easier, quicker and independently of the climate conditions. According to the results obtained in vitro, the most promising systems have then to be tested in whole plants cultivated in controlled and well defined plots or under hydroponic conditions for validation, before any application at large scale. During this project the cooperation of an industrial partner with a basic research laboratory is proposed. The aim of the cooperation is to combine the knowledge of both partners in the field of phytoremediation of TNT and develop a methodology for cleaning of TNT (nitroaromatics) polluted soils and waters.
