The CHLOR2NOU project aims to develop new monitoring tools for CLD and its TPs, to provide new knowledge on the fate and risk of CLD TPs, and to explore realistic alternative approaches for pollution remediation. The postulate of the non-degradability of CLDs commonly admitted for several decades has had a strong negative impact on pollution management by ruling out the possibility of CLD degradation. The representation of CLD in the FWI society and in the scientific community is therefore of paramount importance. The CHLOR2NOU project is divided into 7 Work Packages that bring together scientists from various background: the WP1 with the synthesis of CLD TPs, CLD baits and fluorescent macromolecular cages; the WP2 that deals with innovative analytical methods: (i) routine laboratory method for the detection of CLD TPs in environmental and food matrices, (ii) immunoassay using a CLD-selective antibody, (iii) a semi-high-throughput detection protocol based on the recognition of CLD by a fluorescent macromolecular cage; the WP3 dedicated to toxicological and ecotoxicological studies in order to define the toxicity profile of CLD TPs; the WP4 with several analytical campaigns to obtain a first estimate of the possible exposure to CLD TPs; the WP5 that aims at studying the fate of CLD TPs, in particular in FWI soils, while defining degradation indicators; the WP6 that is focused on the study of realistic agronomic and environmental conditions capable to favor CLD degradation; the last WP centered on the representation of CLD in the FWI society at large. A co-construction method will be used to help the population and stakeholders to better assimilate the scientific results.
