The analysis of persistent organic pollutants (POPs), including polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs), and other persistent organic compounds, primarily relies on gas chromatography coupled with mass spectrometry (GC-MS), the reference technique for their identification and quantification. However, complex matrices from the nuclear sector (sludges, soot, ashes, soils, concrete, etc.) require dedicated sample preparation protocols to ensure reliable analytical results. Interactions between contaminants and the solid matrix, particularly adsorption phenomena, may significantly reduce extraction efficiency.

The objective of this project is to develop and validate robust extraction protocols for the analysis of these contaminants using high-resolution GC-Orbitrap mass spectrometry. Following a comprehensive literature review, the successful candidate will define an experimental strategy, evaluate and compare different sample preparation and extraction methods, and validate the selected protocols before applying them to representative nuclear matrices.

The postdoctoral position will be based at the Institute for Research on Nuclear Systems for Low-Carbon Energy (IRESNE) at CEA Cadarache, France. The successful candidate will develop expertise in the analytical chemistry of complex matrices, with a particular focus on sample preparation, organic contaminant extraction, and GC-Orbitrap analysis. They will design and validate innovative analytical protocols while addressing the specific challenges associated with nuclear matrices. The research outcomes will be disseminated through publications in peer-reviewed journals and presentations at national and international scientific conferences.
