Our expertise

ECT Oekotoxikologie GmbH builds on four pillars of activity and expertise:


In the area of testing, ECT conducts a broad range of ecotoxicological tests at the laboratory, semi-field and field scale in compliance with Good Laboratory Practice (GLP) and according to international test guidelines. Established test systems cover the aquatic (pelagic and benthic) and terrestrial environment, including dung organisms. We also offer selected tests that relate to the environmental fate of chemicals, such as bioaccumulation studies with fish or invertebrates. ECT has extensive experience in adapting tests to special requirements as demanded by scientific or regulatory needs. Several study directors at ECT have more than 10 years of experience in their role, which ensures highly competent support of industry customers and thorough training of our skilled young study directors.


The consultancy team at ECT assembles and evaluates data for the environmental hazard and risk assessment of industrial chemicals under REACH, biocides, plant protection products, pharmaceuticals, mixtures of substances and wastes. We support the preparation and submission of environmental dossiers and provide expert opinions for governmental authorities and industry. Based on broad scientific expertise, we develop strategies to solve problems that may arise during marketing authorisation, registration or classification of chemical substances.


Studies on the effects and the fate of chemicals that are required in the environmental risk assessment within the process of authorisation and registration are generally conducted according to international guidelines. ECT actively contributes to the development, standardisation and validation of such methods, e.g. by organising international ring tests. This activity has in many cases contributed to the establishment of new international guidelines. Examples of major involvement are the sediment-water toxicity test with Lumbriculus variegatus, the reproduction test with the predatory mite Hypoaspis aculeifer, and, more recently, laboratory tests with dung beetles and dung flies.


Through constant participation in and coordination of national and international research projects, ECT keeps up with the state of the art in the field of ecotoxicology and environmental risk assessment. We improve existing or develop new testing methods as well as environmental risk assessment schemes (e.g. for mixtures of chemicals). In addition, ECT is experienced in studying soil biodiversity, both in ecotoxicological field trials and ecological monitoring programs.
