A simple, portable sample pretreatment procedure was optimized to extract the analytes. Home-made columns, packed with a new sorbent material called CYXAD (CYPHOS 101 modified Amberlite XAD), were used to separate the two forms of the analyte. HgTOT and CH3Hg were determined by anodic stripping voltammetry (ASV), using a solid gold electrode (SGE). Two certified reference materials (BCR-463 Tuna Fish and Tuna Fish ERM-CE 464) and eight fresh fishes were analyzed. Then, the results that were obtained following the optimized portable procedure were compared with the concentrations obtained, using a direct mercury analyzer (DMA). This quantification, using the two techniques, demonstrated the good performance of the proposed method.<\/jats:p>","DOI":"10.3390\/molecules27103178","type":"journal-article","created":{"date-parts":[[2022,5,16]],"date-time":"2022-05-16T21:36:06Z","timestamp":1652736966000},"page":"3178","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["On-Site Determination of Methylmercury by Coupling Solid-Phase Extraction and Voltammetry"],"prefix":"10.3390","volume":"27","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8321-8109","authenticated-orcid":false,"given":"Paolo","family":"Inaudi","sequence":"first","affiliation":[{"name":"Department of Drug Science and Technology, University of Torino, Via Pietro Giuria 9, 10125 Turin, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elio","family":"Mondino","sequence":"additional","affiliation":[{"name":"Department of Chemistry, University of Torino, Via Pietro Giuria 7, 10125 Torino, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2350-4941","authenticated-orcid":false,"given":"Ornella","family":"Abollino","sequence":"additional","affiliation":[{"name":"Department of Drug Science and Technology, University of Torino, Via Pietro Giuria 9, 10125 Turin, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8352-0487","authenticated-orcid":false,"given":"Mery","family":"Malandrino","sequence":"additional","affiliation":[{"name":"Department of Chemistry, University of Torino, Via Pietro Giuria 7, 10125 Torino, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8485-7460","authenticated-orcid":false,"given":"Monica","family":"Argenziano","sequence":"additional","affiliation":[{"name":"Department of Drug Science and Technology, University of Torino, Via Pietro Giuria 9, 10125 Turin, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Laura","family":"Favilli","sequence":"additional","affiliation":[{"name":"Department of Drug Science and Technology, University of Torino, Via Pietro Giuria 9, 10125 Turin, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Roberto","family":"Boschini","sequence":"additional","affiliation":[{"name":"FKV SrL, Largo delle Industrie, 10, 24020 Torre Boldone, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6089-7751","authenticated-orcid":false,"given":"Agnese","family":"Giacomino","sequence":"additional","affiliation":[{"name":"Department of Drug Science and Technology, University of Torino, Via Pietro Giuria 9, 10125 Turin, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,5,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"543","DOI":"10.1146\/annurev.ecolsys.29.1.543","article-title":"The Chemical Cycle and Bioaccumulation of Mercury","volume":"29","author":"Morel","year":"1998","journal-title":"Annu.
