CDTA
Centre for Development and Analytical Transfer
The CDTA is a technology transfer unit of the Université de Bordeaux, attached to the Environmental Physics and Toxicochemistry Team (LPTC) of the EPOC (Environnement et Paléoenvironnements Océaniques et Continentaux, CNRS/Université de Bordeaux, INP, EPHE) joint research unit. The CDTA provides services, studies and expertise in the analysis of organic micropollutants in the environment on behalf of various partners.
The CDTA’s major areas of specific expertise include the study of water contamination by emerging contaminants (pharmaceutical substances) and pesticides, and considerable expertise in the field of passive samplers, which can be used to analyse trapped organic pollutants and report on pollution averaged over time. The CDTA also has extensive experience in the field of ultra-trace analysis, developing specific methodologies for characterising concentrations of ppt and ppq (e.g. pesticides, PFAS, chlordecone, bisphenols). The CDTA relies on the Plateforme de chimie analytique organique environnementale (PLATINE) accredited by the University of Bordeaux (UB) and associated with the Réseau Géochimique et Expérimental Français RéGEF via its network of specific instruments GEOF (Géochimie Organique Française).
Platine is a multi-instrument platform combining sample preparation and mass spectrometry analysis. It provides support and technical and scientific expertise for CDTA projects.

Expertises
Expertise : Characterisation of the organic ultra-trace pollution
1.Targeted quantitative ultra-trace approaches :
- Historical organic compounds (‘HAPs’, ‘PCBs’, organochlorine pesticides, etc.).
- Compounds of emerging interest (pharmaceuticals, pesticides, PFAS, biocides, cosmetics, etc.).
- Compounds with biological effects (endocrine disrupters, etc.).
2. Unconventional approaches :
- Global xenometabolomic analysis.
- Characterisation of unknown and/or unregulated compounds (transformation products, etc.).
