Data on different sources of exposure to Ba and possible routes of entry are important for preventing adverse health effects. Blood Ba levels were evaluated in 10 localities in the cities of Barcarena and Abaetetuba in the Amazon. Ba levels were quantified using induced coupled plasma mass spectrometry, and the data were stratified per epidemiological variables and lifestyle habits. The localities were divided into two groups: Group 1, localities wherein individuals had the lowest median levels (0.299\u20131.330 \u00b5g\u00b7L\u22121), and Group 2, localities wherein individuals had the highest median levels (8740\u201337,300 \u00b5g\u00b7L\u22121). Factors such as duration of residency, sex, age, smoking status, and alcohol consumption significantly contributed to the increase in exposure. The highest concentrations were associated with drinking water sources such as underground wells and local rivers, as well as the consumption of fish. This is the first study to record Ba exposure in individuals living in localities close to the industrial areas in the Amazon. These findings may facilitate the development of new health surveillance policies and the implementation of preventive measures.<\/jats:p>","DOI":"10.3390\/ijerph22010109","type":"journal-article","created":{"date-parts":[[2025,1,15]],"date-time":"2025-01-15T05:59:42Z","timestamp":1736920782000},"page":"109","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["The First Report of Environmental Exposure to Barium in 10 Localities Close to Industrial Areas and Ports in the Amazon"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0687-2048","authenticated-orcid":false,"given":"Brenda Rodrigues","family":"Chagas","sequence":"first","affiliation":[{"name":"Programa de P\u00f3s-Gradua\u00e7\u00e3o em Sa\u00fade Coletiva, Instituto de Estudos em Sa\u00fade Coletiva, Universidade Federal do Rio de Janeiro (IESC\/UFRJ), Rio de Janeiro 21941-901, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6596-6653","authenticated-orcid":false,"given":"Volney","family":"de Magalh\u00e3es C\u00e2mara","sequence":"additional","affiliation":[{"name":"Programa de P\u00f3s-Gradua\u00e7\u00e3o em Sa\u00fade Coletiva, Instituto de Estudos em Sa\u00fade Coletiva, Universidade Federal do Rio de Janeiro (IESC\/UFRJ), Rio de Janeiro 21941-901, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9859-0341","authenticated-orcid":false,"given":"Karytta Sousa","family":"Naka","sequence":"additional","affiliation":[{"name":"Programa de P\u00f3s-Gradua\u00e7\u00e3o em Sa\u00fade Coletiva, Instituto de Estudos em Sa\u00fade Coletiva, Universidade Federal do Rio de Janeiro (IESC\/UFRJ), Rio de Janeiro 21941-901, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tha\u00eds Karolina Lisboa","family":"de Queiroz","sequence":"additional","affiliation":[{"name":"Programa de P\u00f3s-Gradua\u00e7\u00e3o em Sa\u00fade Coletiva, Instituto de Estudos em Sa\u00fade Coletiva, Universidade Federal do Rio de Janeiro (IESC\/UFRJ), Rio de Janeiro 21941-901, Brazil"},{"name":"Se\u00e7\u00e3o de Meio Ambiente (SAAMB), Instituto Evandro Chagas, Secretaria de Vigil\u00e2ncia em Sa\u00fade e Ambiente, Minist\u00e9rio da Sa\u00fade (IEC\/SVSA\/MS), Ananindeua 67030-000, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1981-6822","authenticated-orcid":false,"given":"Lorena","family":"de C\u00e1ssia dos Santos Mendes","sequence":"additional","affiliation":[{"name":"Se\u00e7\u00e3o de Meio Ambiente (SAAMB), Instituto Evandro Chagas, Secretaria de Vigil\u00e2ncia em Sa\u00fade e Ambiente, Minist\u00e9rio da Sa\u00fade (IEC\/SVSA\/MS), Ananindeua 67030-000, Brazil"},{"name":"Programa de P\u00f3s-Gradua\u00e7\u00e3o em Epidemiologia e Vigil\u00e2ncia em Sa\u00fade (PPGEVS\/IEC\/SVSA\/MS), Instituto Evandro Chagas (IEC), Ananindeua 67030-000, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Iracina Maura","family":"de Jesus","sequence":"additional","affiliation":[{"name":"Se\u00e7\u00e3o de Meio Ambiente (SAAMB), Instituto Evandro Chagas, Secretaria de Vigil\u00e2ncia em Sa\u00fade e Ambiente, Minist\u00e9rio da Sa\u00fade (IEC\/SVSA\/MS), Ananindeua 67030-000, Brazil"},{"name":"Programa de P\u00f3s-Gradua\u00e7\u00e3o em Epidemiologia e Vigil\u00e2ncia em Sa\u00fade (PPGEVS\/IEC\/SVSA\/MS), Instituto Evandro Chagas (IEC), Ananindeua 67030-000, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3983-1672","authenticated-orcid":false,"given":"Marcelo","family":"de Oliveira Lima","sequence":"additional","affiliation":[{"name":"Associa\u00e7\u00e3o Brasileira de Sa\u00fade Coletiva (ABRASCO), Rio de Janeiro 21040-900, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5258-8016","authenticated-orcid":false,"given":"Armando","family":"Meyer","sequence":"additional","affiliation":[{"name":"Programa de P\u00f3s-Gradua\u00e7\u00e3o em Sa\u00fade Coletiva, Instituto de Estudos em Sa\u00fade Coletiva, Universidade Federal do Rio de Janeiro (IESC\/UFRJ), Rio de Janeiro 21941-901, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,1,15]]},"reference":[{"key":"ref_1","first-page":"472","article-title":"Trace element analysis in hair: Factors determining accuracy, precision, and reliability","volume":"6","author":"Bass","year":"2001","journal-title":"Altern.
