PM and soil samples were collected during the 2016–2017 austral summer season at the surroundings of the Spanish Antarctic Research Station “Gabriel de Castilla” (Deception Island, South Shetland Islands). PM was deposited in a low-volume sampler air filter. Raman spectroscopy (RS) and Scanning Electron Microscopy with Energy-Dispersive X-ray Spectroscopy (SEM-EDS) were used to determine the elemental and molecular composition of the individual aerosol and soil particles. Filter spectra measured by these techniques revealed long-range atmospheric transport of organic compounds (polystyrene and bacteria), local single and cluster particles made of different kinds of black carbon (BC), exotic minerals (polyhalite, arcanite, niter, ammonium nitrate, syngenite and nitrogen, phosphorus, and potassium (NPK) fertilizer), and natural PM (sea salts, silicates, iron oxides, etc.). In addition to the filter samples, forsterite and plagioclase were discovered in the soil samples together with magnetite. This is the first report of the presence of a microplastic fiber in the Antarctic air. This fact, together with the presence of other pollutants, reflects that even pristine and remote regions are influenced by anthropogenic activities. 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/semantics/openAccess by-nc-nd https://creativecommons.org/licenses/by-nc-nd/4.0/deed.es 4.4 2022 SPECTROSCOPY 5 / 41 = 0.122 2022 Q1 T1 0.635 2022 Analytical Chemistry 2022 Q2 Spectroscopy 2022 Q2 Instrumentation 2022 Q2 Atomic and Molecular Physics, and Optics 2022 Q2 7.9 2022 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Perez-Arribas, Luis, V.
