Aquatic tests
Plant protection agents cannot usually be limited to the area to which they are applied. They will enter surrounding bodies of water, e.g. by being washed off after rain. Therefore, it must be ensured that they or their degradation products do not negatively influence the ecosystem there.
Our service
We offer a broad range of aquatic toxicity tests for plant protection agents, pharmaceuticals, biocides and other chemicals. The studies are conducted according to the OECD/ISO/EPA directives under GLP conditions.
