Because of that, the study of atmospheric aerosols looking for harmful pollutants is rising, as well as the interest in the origin of the contaminants. Depending on the nature and size of the aerosols, some elements can be detected at a great distance from the emission source, even in Antarctica, where this study is conducted. Several samples of PM filters from 2018 to 2019 (Deception Island) and 2019–2020 (Livingston Island) campaigns have been analyzed by three powerful spectroscopic techniques: FESEM (Field Emission Scanning Electron Microscopy), LIBS (Laser Induced Breakdown Spectroscopy), and ICP-MS (Inductively Coupled Plasma Mass Spectrometry). These techniques have allowed us to find some heavy metals in the air of the Antarctic region (Al, Fe, Ti, Ni, Cr, and Mn). Deeper studies on ICP-MS results have confirmed those results and have also provided information on their potential sources. Thus, while Al, Fe, Ti and Mn concentrations can be explained by crustal origin, Ni and Cr presented high values only coherent with important human contribution. The results point out that the Antarctic region is no longer a clean and isolated environment from human pollution. info:eu-repo/grantAgreement/ES/DGA/E23-17D info:eu-repo/grantAgreement/ES/DGA/E49-20R info:eu-repo/grantAgreement/ES/MCINN/CTM2017-82929-R info:eu-repo/grantAgreement/ES/UZ/UZ2021-CIE-01 info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 8.8 2022 ENVIRONMENTAL SCIENCES 30 / 275 = 0.109 2022 Q1 T1 1.727 2022 Chemistry (miscellaneous) 2022 Q1 Environmental Chemistry 2022 Q1 Environmental Engineering 2022 Q1 Public Health, Environmental and Occupational Health 2022 Q1 Medicine (miscellaneous) 2022 Q1 Pollution 2022 Q1 Health, Toxicology and Mutagenesis 2022 Q1 13.3 2022 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Marina-Montes, César Universidad de Zaragoza (orcid)0000-0001-5652-3677 Laguna, Mariano (orcid)0000-0002-5801-3352 Lasheras, Roberto Rivas, Patricia Peribáñez, Pablo Valle, Javier del (orcid)0000-0002-9414-4720 Escudero, Miguel Universidad de Zaragoza (orcid)0000-0001-8227-5689 Velásquez, Abrahan (orcid)0000-0002-0010-4729 Cáceres, Jorge O.
