Aquatic Organisms
ECT offers a wide range of aquatic ecotoxicological standard tests under GLP according to OECD, EPA and ISO guidelines. We can adapt test designs to the specific requirements of a test substance. We further develop and conduct tests with non-standard test species and multi-species systems and we are familiar with species sensitivity distributions.
