Quality of Soils and Water

In this research topic we focus on quality assessments for soil and water, as determined by the German Federal Soil Protection Act, the EU Water Framework Directive and the German Ordinance on the Protection of Surface Waters.

Furthermore, we carry out studies that investi­gate priority setting with respect to (legal) measures related to the im­plementation of the Water Frame­work Directive, e.g., the derivation of chemical environ­mental quality standards for water, sediment and biota. Water and sediment quality is investigated using biomarkers and bioas­says and by ecological monitoring.

To describe the influence of surface water properties on the biological availability and effects of metals such as copper, nickel and zinc biotic ligand models (BLM) have been developed. BLMs allow assessing possible effects of dissolved metal concentrations in waters by considering local water parameters such as pH, dissolved organic carbon (DOC) and calcium concentrations. By this approach generic environmental quality standards for metals derived from risk assessment can be adapted to local water conditions. Fraunhofer IME is involved in a IUPAC project which evaluates advantages and possible drawbacks of BLM and BLM-based software tools and develops recommendations for an appropriate implementation.

Metal bioavailability

We also devel­op and apply strategies to determine existing or potential hazards for natu­ral soil functions caused by the impact of anthropo­genic activities. In this context (bio-)availability is considered.

The structure of a community at a site, the ensemble of species and their abundance, is an excellent integrator of present and past exposure to stress. Thus, ecological monitoring is also an important tool to assess the ecological quality of water bodies.

In ecological monitoring projects we closely cooperate with external partners which are experts of the local fauna and flora to be monitored.  The Fraunhofer IME coordinates the projects and is responsible for statistical evaluation and assessment of the results.
