Database of polychlorinated dibenzo-p-dioxins, dibenzofurans and dioxin-like and non-dioxin like polychlorinated biphenyls in bivalves from Shellfish Production Areas in the Basque coast (southeastern Bay of Biscay)
Description
This dataset presents the levels of 17 polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs), and 12 dioxin-like polychlorinated biphenyls (DL-PCBs) (PCB-81, PCB-77, PCB-126, PCB-169, PCB-123, PCB-118, PCB-114, PCB-105, PCB-167, PCB-156, PCB-157 and PCB-189) in bivalves collected annually from 2008 to 2023 in the Shellfish Production Areas of the Basque coast (southeastern Bay of Biscay). Additionally, data on 6 non-dioxin like polychlorinated biphenyls (NDL-PCBs) (PCB-28, PCB-52, PCB-101, PCB-153, PCB-138 and PCB-180) are provided for the 2012-2023 time period. Depending on the availability of bivalves at each Shellfish Production Area, different species, such as mussels (Mytilus galloprovincialis) and oysters (Magallana gigas and Ostrea edulis), were used for the evaluation. Bivalve samples were analyzed following standardized methodologies according to the specific requirements established at the corresponding EU Regulations. This work was supported by the Fisheries and Aquaculture Directorate, Department of Economic Development, Sustainability and Environment of the Basque Government through CULTIVOS Project.

Steps to reproduce
This database can be accessed with any standard database manager or spreadsheet software. It should be taken into account that different species of bivalve mollusks have been used during the study period and at different sampling points. It should be taken into account that the locality of Mendexa corresponds to open waters and sampling began in 2013. In contrast, the other locations are estuarine and sampling began in 2008.
