Aquatic Toxicology

SynTech Research’s Aquatic Ecotoxicology Team at  ECT Oekotoxikologie GmbH in Germany, located near Frankfurt airport, provides complete aquatic study programs under GLP.

Our highly experienced Study Directors are supported by well-trained technicians and can rely on an efficient Quality Assurance team to deliver timely, high quality studies to our customers.

Programmes offered range from single First tier standard studies to complex packages including Higher tier studies with, for example, variable exposure designs. Our testing capabilities include acute and chronic laboratory toxicity tests on fish, invertebrates, algae and aquatic macrophytes, and sediment-dwelling organisms as well as bioaccumulation studies with fish and aquatic invertebrates. Test organisms originate from our in-house cultures, and we have broad experience with setting up cultures and toxicity test with non-standard species.
