ECT Oekotoxikologie We are a private enterprise that was founded in 1993. In compliance with Good Laboratory Practice (GLP) and DIN EN ISO/IEC 17025 accreditation, we perform standardised ecotoxicological tests in the laboratory as well as semi-field and field studies. Established test systems cover the aquatic, benthic and terrestrial environment and also include dung organisms. In addition to performing standardised tests, we modify existing or develop new methods to improve the characterisation of environmental risks caused by chemicals. The results of our experimental and desk-based studies are used in the environmental risk assessment of industrial chemicals (REACH), biocides, pharmaceuticals, plant protection products, wastes and genetically modified organisms.
