Determining acute toxicity
We perform tests to determine the acute toxicity of substances and thus provide information that may be used for regulatory purposes. These tests can be divided into two categories:
- the tests recommended by the OSPAR Commission which are conducted on four species representative of the different trophic levels of the aquatic ecosystem: an algae, a copepod, an amphipod and a fish
- dispersant tests on a species of marine shrimp.
Determining sublethal toxicity
We also carry out experiments on aquatic organisms in order to determine how hazardous a product is by identifying its sublethal effects. These effects can influence the behaviour, growth, reproduction and/or immunology of the individuals affected.
Accreditation for the protection and health surveillance of animals and plants
In July 2020, Cedre was granted a 5-year renewal of its accreditation issued by the Finistère Departmental Directorate for the Protection of the Population (animal and plant protection and health surveillance department), as an establishment using animals for scientific purposes.
For this, Cedre’s staff includes four level I animal testing licence holders, one level II licence holder as well as a captive wildlife permit holder.
