MONITOOL Project: dataset of metal concentrations in seawater from European estuaries and coastal sites measured by Diffusive Gradients in Thin-films (DGT) passive samplers and spot sampling.
This dataset presents metal concentrations in transitional and coastal waters measured in Diffusive Gradients in Thin-films (DGT) passive samplers by Inductively Coupled Plasma Mass Spectrometry (ICP-MS: Cd, Co, Cu, Fe, Mn, Ni, Pb, Zn) and in concurrently collected spot samples by ICP-MS (Al, Cd, Co, Cu, Mn, Ni, Pb, Zn) and Anodic/Cathodic Stripping Voltammetry (ASV/CSV: Cd, Ni, Pb) and obtained in the framework of the MONITOOL Project. Data on seawater physico-chemical parameters is also provided (salinity, temperature, dissolved oxygen, pH, turbidity, total suspended solids, dissolved organic carbon, total organic carbon). Sampling sites include the following ecoregions: Canary Islands, Iberian Coast, Bay of Biscay and English Channel, Celtic Sea North Sea and Western Mediterranean Sea (for detailed description of sampling sites see Caetano et al., Marine Pollution Bulletin 179 (2022) 113715). ICP-MS and voltammetry analysis (Anodic Stripping Coltammetry: Cd and Pb; Cathodic Stripping Voltammetry: Ni) were carried out in filtered seawater (see Bersuder et al., MethodsX 8 (2021) 101462; Rodríguez et al., Science of the Total Environment 783 (2021) 147001; Amouroux et al., Environmental Sciences Europe (2023) 35:29). Detailed description of the DGT technique and a user-friendly guidance can be found in Millán et al. (2021. A Good Practice Guide for the Use of DGTs. ITC. ISBN: 978-84-09-30846-0) and Gonzalez et al. (Science of the Total Environment 847 (2022) 157499). More info: https://www.monitoolproject.eu.
Steps to reproduce
Tips to use the database: i) This database can be accessed with any standard database manager or spreadsheet software. ii) If you want to compare the concentrations measured with passive samplers vs. spot sampling, you have to take into account the exposure time of DGT passive samplers. The exposure time is indicated in the column ' Sampling DGT Deployment time (days)’; i.e., this refers to the number of days the passive sampler has been submerged in water. The retrieval date (‘Sampling Date’) and retrieval time (‘Sampling Time’) of passive samplers are also given. The date and time of the start of deployment of the passive sampler is not given but can be calculated indirectly from available information. As an example, at DEBA sampling site, the passive samplers retrieved on February 16, 2018 at 17:13 had a deployment time of 4.273842593 days, that means that these passive samplers were placed in the water on February 12, 2018 at 10:39. iii) It should be noted that not all the variables are available for each time and site. iv) It should be noted that passive samplers were exposed in replicates (see field ‘Result Field Replicate’). v) It should be noted that in some cases spot sample replicates were collected for voltammetry analyses (see field ‘Result Field Replicate’). vi) Any errors that are detected may be reported to the following e-mails: grodriguez[at_sign]azti.es; nmontero[at_sign]azti.es
