To record the effect of surface-bound pollutants in the aquatic environment and in soils, we carry out contact tests with
- Fish eggs
- Aquatic plants (Myriophyllum spec.)
- and nematodes (nematodes)
through. The test organisms are exposed to aquatic sediments, soils or other finely granulated materials in defined test solutions. The contact tests record the effects of substances that are mediated by the direct contact of the test organisms with the solids or by pore water.
