Testing of Potential Endocrine Disruptors

ibacon offers a wide variety of ecotoxicological studies for the testing of potential endocrine disruptors. For agrochemicals, biocides and industrial chemicals testing of endocrine activity is required in case the substance is assumed to have an endocrine disrupting potential. For those three groups of chemicals the classification of a substance as endocrine disruptor is a cut-off criterion, resulting in restriction of registration.

We have been performing many of these studies regularly also for other purposes and we have a vast know-how with the relevant species and test performance. Take your advantage and discuss your needs with us!
