Anthropogenic chemicals such as pesticides or pharmaceuticals are distributed over large areas or regionally limited in the environment. Our research group is investigating the transport, binding and transformation of such substances in water, soil, plants and other organisms. We are also interested in substance residues that are immobilized or fixed in soils and plants and can no longer be extracted. In addition to their chemical structure, the question under which conditions and in what form such "bound residues" are bioavailable, i.e. can be taken up by plants or animals, is of particular importance.
We are developing techniques to reduce the concentration of problematic substances in soil and water with the help of plants and microorganisms. An important aspect is the selection of plants, which on the one hand should be as insensitive as possible to the contaminant in question, but on the other hand are able to absorb it in sufficient quantities.
In addition to the ecotoxicological assessment, the fate of such pollutants is an important aspect of the environmental risk assessment of chemicals. We contribute such knowledge to relevant expert committees.
