Environmental Fate

ECT offers to manage a range of environmental fate tests in the context of study packages. These tests are subcontracted to established and experienced partners to be performed under GLP and in compliance with the relevant guidelines. Adapted test designs can be developed in response to specific scientific or regulatory interest. Tests are conducted with radio-labelled and non-labelled test substances. For bioaccumulation and bioconcentration studies see here.
