Current techniques for continuous PM monitoring are usually complex, costly, time consuming and do not provide real-time measurements. In this work, based on micro laser-induced breakdown spectroscopy (LIBS), an innovative method with an optical design and multi-elemental scanning imaging, is presented to characterize PM collected in filters from Antarctica. After following a simple protocol and under atmospheric pressure, the new approach allows to obtain a global visualization of the elemental PM composition of the filters with a minimum sample destruction and preparation. For the first time, we were able to map the localization of pollutants in filters at high spatial resolution and speed. This recent method offers a new insight on the characterization of PM, particularly in isolated areas, where no complex equipment and real time measurements are demanded. info:eu-repo/grantAgreement/ES/AEI/CTM2017-82929-R info:eu-repo/grantAgreement/ES/DGA/E23-17D info:eu-repo/grantAgreement/ES/DGA/E49-20R info:eu-repo/grantAgreement/ES/MICINN/PID2020--112570RB-C2 info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 6.911 2021 CHEMISTRY, ANALYTICAL 10 / 87 = 0.115 2021 Q1 T1 1.105 2021 Analytical Chemistry 2021 Q1 Spectroscopy 2021 Q1 Environmental Chemistry 2021 Q1 10.5 2021 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Motto-Ros, Vincent Pérez-Arribas, Luis Vicente Anzano, Jesús Universidad de Zaragoza (orcid)0000-0002-8581-4972 Millán-Martínez, María Cáceres, Jorge O. 2009 750 Universidad de Zaragoza Dpto.
