Polychlorinated Biphenyls (PCB) indicators in sediments from the main French Rivers from 1945 to 2018 (Garonne, Loire, Rhône, Seine)

We collected PCB analysis results from multiple sources (French Water Basin Agencies, Port Authorities, Research Laboratories) to produce a spatio-temporal database of PCB contamination in sediments along the main French Rivers (source-estuary) from 1945 to 2018. This database contains data from bed and flood deposits, cores, suspended particulate matter and dredged sediments. It presents sediment concentrations of PCB indicators (PCB28, 52, 101, 118, 138, 153, 180; µg/kg) and their sum or reconstructed sum according to the porportion of highly chlorinated congeners (PCB 138, 153 and 180).
