Both of these methods consume a large amount of chemicals and require long pretreatment times because of several complicated MeHg extraction steps. Objective: In this study, a new method for the simple and rapid determination of MeHg in fish has been developed. The method is based on the investigation of oxygen combustion\u2013gold amalgamation using a direct mercury analyzer (DMA) after the complete removal of MeHg by organic extraction and back-extraction to an aqueous medium. Methods: The DMA is suitable for the analysis of both solid and liquid materials and has a good detection limit. The developed method was validated by comparing the MeHg recoveries (%) of both certified reference materials and the market-purchased fish samples with the MeHg concentration obtained using the KFC method. Results: The following parameters pertaining to the developed method were established: detection limit, 1.02 \u03bcg\/kg; LOQ, 3.09 \u03bcg\/kg; linearity (r), 0.9998; range, 0.1\u2013300 \u03bcg\/kg; and recovery, 95\u201397%. Conclusions: Our method is a promising alternative by virtue of its much simpler and faster sample pretreatment procedure, with a MeHg recovery as high as that of the KFC method. Highlights: The developed method enables the simultaneous analysis of total Hg and MeHg with only DMA equipment.<\/jats:p>","DOI":"10.5740\/jaoacint.18-0254","type":"journal-article","created":{"date-parts":[[2019,9,20]],"date-time":"2019-09-20T01:12:07Z","timestamp":1568941927000},"page":"244-249","source":"Crossref","is-referenced-by-count":10,"title":["Methylmercury Determination in Fish by Direct Mercury Analyzer"],"prefix":"10.1093","volume":"103","author":[{"given":"Tae-Hun","family":"Kim","sequence":"first","affiliation":[{"name":"Ministry of Food and Drug Safety, National Food and Drug Safety Evaluation, Food Safety Evaluation Department, Food Contaminants Division, Osong, Cheongju 28159, Republic of Korea"},{"name":"Daejeon Metropolitan City Institute of Health and Environment, Noeun Inspection Office for Agricultural, Fishery and Livestock Products, Yuseong-gu, Daejeon 34146, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Min-Ja","family":"Cho","sequence":"additional","affiliation":[{"name":"Ministry of Food and Drug Safety, National Food and Drug Safety Evaluation, Food Safety Evaluation Department, Food Contaminants Division, Osong, Cheongju 28159, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yongmin","family":"Lee","sequence":"additional","affiliation":[{"name":"Ministry of Food and Drug Safety, National Food and Drug Safety Evaluation, Food Safety Evaluation Department, Food Contaminants Division, Osong, Cheongju 28159, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ji Hui","family":"Kim","sequence":"additional","affiliation":[{"name":"Ministry of Food and Drug Safety, National Food and Drug Safety Evaluation, Food Safety Evaluation Department, Food Contaminants Division, Osong, Cheongju 28159, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jeong-Yun","family":"Hwang","sequence":"additional","affiliation":[{"name":"Ministry of Food and Drug Safety, National Food and Drug Safety Evaluation, Food Safety Evaluation Department, Food Contaminants Division, Osong, Cheongju 28159, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hye-Eun","family":"Lee","sequence":"additional","affiliation":[{"name":"Ministry of Food and Drug Safety, National Food and Drug Safety Evaluation, Food Safety Evaluation Department, Food Contaminants Division, Osong, Cheongju 28159, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sheen-Hee","family":"Kim","sequence":"additional","affiliation":[{"name":"Ministry of Food and Drug Safety, National Food and Drug Safety Evaluation, Food Safety Evaluation Department, Food Contaminants Division, Osong, Cheongju 28159, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jang-Duck","family":"Choi","sequence":"additional","affiliation":[{"name":"Ministry of Food and Drug Safety, National Food and Drug Safety Evaluation, Food Safety Evaluation Department, Food Contaminants Division, Osong, Cheongju 28159, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gil-Jin","family":"Kang","sequence":"additional","affiliation":[{"name":"Ministry of Food and Drug Safety, National Food and Drug Safety Evaluation, Food Safety Evaluation Department, Food Contaminants Division, Osong, Cheongju 28159, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2020,1,29]]},"container-title":["Journal of AOAC INTERNATIONAL"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/academic.oup.com\/jaoac\/article-pdf\/103\/1\/244\/38936075\/jaoacint.18-0254.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"http:\/\/academic.oup.com\/jaoac\/article-pdf\/103\/1\/244\/38936075\/jaoacint.18-0254.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2021,7,13]],"date-time":"2021-07-13T16:22:36Z","timestamp":1626193356000},"score":1,"resource":{"primary":{"URL":"https:\/\/academic.oup.com\/jaoac\/article\/103\/1\/244\/5717529"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,1,1]]},"references-count":0,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2020,1,29]]},"published-print":{"date-parts":[[2020,1,1]]}},"URL":"https:\/\/doi.org\/10.5740\/jaoacint.18-0254","relation":{},"ISSN":["1060-3271","1944-7922"],"issn-type":[{"value":"1060-3271","type":"print"},{"value":"1944-7922","type":"electronic"}],"subject":[],"published-other":{"date-parts":[[2020,1]]},"published":{"date-parts":[[2020,1,1]]}}}
