3. Effects of emerging pollutants on biota and the environment
Since 2016, the LBBM has developed activities aimed at assessing the impact of xenobiotics on the marine environment, using standardized methods and developing new approaches to evaluate the toxic effects, both lethal and sublethal, of xenobiotics on marine organisms. In particular, an innovative non-targeted metabolomics analysis approach has been implemented on reef-building corals, representing a significant advancement in understanding the impact of xenobiotics on corals and their fate in the marine ecosystem.
Additionally, the laboratory also investigates the impact of emerging pollutants on soil microorganisms in the vicinity of Perpignan, using a multidisciplinary approach that combines analytical chemistry techniques (HPLC), omics methods (sequencing and metabarcoding), ecotoxicological tests in biochemistry, as well as the screening of microbial strains.
Some recent examples of publications from the LBBM in this field include:
