Abstract. Environmental pollution by polychlorinated biphenyls (PCBs) is a key cause for concern about river quality because of their low degradation rates leading to their accumulation in sediments and living organisms. An original interdisciplinary work was conducted along the four main French rivers (Seine, Rhône, Loire and Garonne rivers), which flow into major European seas. We completed a dataset based on sediment analyses provided by monitoring agencies, port authorities and research teams on different solid matrices (sediment cores, bed and flood deposits, suspended particulate matter and dredged sediments). This dataset focused on the seven indicator PCBs and their sum (ΣPCBi) from 1945 to 2018 (nΣPCBi =1416). Special effort was put into the quality control to provide robust spatio-temporal information. Taking into account hydrological and human drivers, we outlined two main pollution trends: (1) from 1945 to 1975, a quick increase in ΣPCBi (up to 4 mg kg−1 dry weight, dw) and a sharp decrease in the 1980s on the Seine and Loire rivers and (2) increasing but moderate ΣPCBi levels (50 to 150 µg kg−1 dw) followed by a decline after the 1990s on the Rhône and Garonne rivers. In addition to these patterns, PCB emissions from urban and industrial areas or accidental events were significant in each river. Finally, when calculating specific flux, the Rhône exhibited the uppermost ΣPCBi load (up to 12 µgm-2yr-1 in 1977–1987), at least 25 % higher than those of the Seine and Loire rivers, while the Garonne showed a very low flux. In western Europe, we confirmed that the Rhône, Seine and Loire rivers contribute significantly to the PCB contamination of the seas, while French specific ΣPCBi fluxes are 2 orders of magnitude lower than those found in American or Asian rivers. The dataset is available at https://doi.org/10.1594/PANGAEA.904277 (Dendievel et al., 2019).

“…The sediment deposits in Martot Pond are characterised by two sedimentary facies, as previously described by Gardes et al (2020b). The "Seine Unit" facies corresponds to sediment deposits from the Seine River watershed until the early 1940s, when Martot Pond was connected to the Seine channel.…”

“…The grain size distribution exhibited a low D 50 (D 50 = 13.8 ± 7.0 μm), the TOC content (TOC mean = 1.75 ± 0.33%) was low, HI (HI mean = 147 ± 24 mg HC g -1 TOC) was constant, OI (OI mean = 260 ± 35 mg O2 g -1 TOC) increased to 103.5 cm followed by a decrease, and the average RC/TOC was 0.76 ± 0.01. The "Eure Unit" facies, for which an age model has been established, corresponds to the Eure River inputs since the 1940s, with a sedimentation rate of 12.73 ± 2.2 mm y -1 (Gardes et al, 2020b). For this facies, the grain size distribution was centred around a D 50 of 33.9 ± 7.8 μm and the TOC content (TOC mean = 3.88 ± 1.49%) increased towards the surface, with high contents (TOC = 8.26 ± 0.19%) in the 9-12 cm range.…”

“…The main Seine estuary tributary is the Eure River. Moreover, the Eure River watershed was recently found to carry significant heavy metal burdens since the 1940s, which may have impacted the sediment quality of the Seine estuary (Gardes et al, 2020a(Gardes et al, , 2020b. Therefore, this study aimed to establish a link between sediment deposit characteristics and POPs, as well as to reconstruct the temporal trends in PAHs and PCBs accumulation based on sediment cores collected downstream of the Eure River watershed.…”
