On the other hand, most sands and soils possess significant amounts of iron, manganese or other metallic species that often provide excessively broad EPR signatures combined with well-defined sharp features by quartz defects. In this study, we demonstrate the feasibility to identify oil contamination in natural environments that are subject to oil spillage during production on land, as well as beachside accumulation of marine oil spillage. Straightforward identification of oil is enabled by the radical contributions of asphaltenes, in particular by vanadyl multiplets that are absent from natural soils. This potentially allows for high-throughput soil analysis or the application of mobile EPR scanners. article Papmahl, Eric VerfasserIn Author aut Mattea, Carlos 1966- VerfasserIn Author aut (DE-588)131718916 Stapf, Siegfried 1965- VerfasserIn Author aut (DE-588)130665630 Technische Universität Ilmenau Fakultät für Mathematik und Naturwissenschaften host institution his 52(2021), 5, Seite 633-648 52, 2021:5<633 Technische Universität Ilmenau, Universitätsbibliothek Applied magnetic resonance Enthalten in 1613-7507 dbt_mods_00050302 Department of General Physics and Astronomy and Kazan Physical-Technical Institute of the Academy of Science of USSR 1.1990 - https://www.db-thueringen.de/receive/dbt_mods_00050304 object in context https://www.db-thueringen.de/servlets/MCRFileNodeServlet/dbt_derivate_00054700/1613-7507_52_2021_5_633-648.pdf raw object https://www.db-thueringen.de/rsc/thumbnail/dbt_mods_00050304.png preview http://uri.gbv.de/document/gvk:ppn:1757457933 uri
