This project will merge the expertise and contributions of three French leading laboratories with strong historical background and internationally recognized expertise in the exposomics research area (performing cutting edge research in analytical chemistry, statistics, exposure science, epidemiology, toxicology and risk assessment) gather their skills in an ambitious research program focused on the development and implementation of a new large-scale suspect and non-targeted screening approach for extensive characterization of human exposure to pesticides. The present post-doctoral position is opened will be based at LABERCA (UMR 1329 Oniris-INRAE) in Nantes, that have all facilities and cutting-edge mass spectrometry instrumentation (MS/MS and HRMS) to assess human exposure to organic mixtures.
The Screenpest project aims to (i) propose a methodology for the large-scale characterization of human internal exposure to pesticides, based on an innovative approach of “suspect screening” by high-resolution mass spectrometry and (ii) generate new exposure data and test possible associations between the exposure levels and certain health parameters from cohort studies. With regard to the first objective, i.e. to cover the widest part possible of the chemical exposome, this will imply on one hand the development, improvement and harmonization of sample preparation methods for human urine, complementary HRMS-based methods with special emphasis on GC-HRMS based workflow, and on the other hand the elaboration of bioinfomatic tools for the treatment of the generated data with use of a dedicated spectral database efficient annotation.
