Environmental Fate

ECT offers a range of environmental fate tests under GLP in compliance with national and international guidelines. Tests are either conducted in house or in cooperation with established partners. Additional test designs can be developed in response to specific scientific or regulatory interest. We can conduct studies with radio-labelled as well as non-labelled test substance.
