| description |
Soils around coal mining are important reservoir of hazardous elements (HEs), nanominerals, and ultrafine compounds. This research reports and discusses the soil concentrations of HEs (As, Cd, Cr, Cu, Ni, Pb, and Zn) in coal residues of abandoned mines. To assess differences regarding environmental impact and risk assessment between coal abandoned mines from the Santa Catarina state, eighteen coal cleaning rejects with different mineralogical and chemical composition, from eight abandoned mines were collected. Nanominerals and ultra-fine minerals from mining-contaminated areas were analyzed by X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), and high-resolution transmission electron microscope (HR-TEM), providing new information on the mineralogy and nano-mineralogy of these coal residues. The total contents of 57 elements (HEs, alkali metals, and rare earth elements) were analyzed by Inductively Coupled Plasma Mass Spectrometry (ICP-MS). The calculation of NWACs (Normalized Average Weighted Concentration), together with the chemometric analysis by Principal component analysis (PCA) confirmed the variability of the samples regarding their city and their mine of origin. Moreover, the results confirmed the existence of hotspots in mines near urban areas. |

Esta investigación informa y analiza las concentraciones en el suelo de EE (As, Cd, Cr, Cu, Ni, Pb y Zn) en residuos de carbón de minas abandonadas. Para evaluar las diferencias con respecto al impacto ambiental y la evaluación de riesgos entre las minas abandonadas de carbón del estado de Santa Catarina, se recolectaron dieciocho rechazos de limpieza de carbón con diferentes composiciones mineralógicas y químicas, de ocho minas abandonadas. Los nanominerales y los minerales ultrafinos de las áreas contaminadas por la minería se analizaron mediante difracción de rayos X (DRX), microscopía electrónica de barrido de emisión de campo (FE-SEM) y microscopio electrónico de transmisión de alta resolución (HR-TEM), que proporcionaron nueva información sobre La mineralogía y nano-mineralogía de estos residuos de carbón. El contenido total de 57 elementos (HEs, metales alcalinos y elementos de tierras raras) se analizó mediante espectrometría de masas de plasma de acoplamiento inductivo (ICP-MS). El cálculo de los NWACs (Concentración ponderada promedio normalizada), junto con el análisis quimiométrico por análisis de componentes principales (PCA) confirmó la variabilidad de las muestras con respecto a su ciudad y su mina de origen. Además, los resultados confirmaron la existencia de hotspots en minas cerca de áreas urbanas.Fdez Ortiz De Vallejuelo, Silvia-00d021c4-6aeb-4d4d-90b0-7bc69fca5a35-0Gredilla, Ainara-746084eb-c4aa-49d2-8893-16940c83d90a-0Da Boit Martinello, Katia-b5155ff5-f2e0-4622-9568-50d1b77b8828-0Calesso Teixeira, Elba-abb31af3-2e67-484f-8a31-541e1cb66c18-0Sampaio Hoffmann, Carlos-c9f0a22c-e91c-49f7-8219-dddd0ef6f0c5-0Madariaga, Juan Manuel-2e2778a5-21ee-4def-8143-f3443dcaa560-0Silva Oliveira, Luis Felipe-5c1c9b54-f160-4f3c-bcd5-b9f532c778af-0engUniversidad de la CostaAttribution-NonCommercial-ShareAlike 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-sa/4.0/info:eu-repo/semantics/openAccesshttp://purl.org/coar/access_right/c_abf2Coal mining soilHazardous elements contaminationHotspot identificationNormalized Average Weighted Concentration (NWACs)Principal componentSuelo mineroContaminación por elementos peligrososIdentificación de punto de accesoConcentración ponderada promedio normalizada (NWAC)Componente principalNanominerals and potentially hazardous elements from coal cleaning rejects of abandoned mines: Environmental impact and risk assessmentNanominerales y elementos potencialmente peligrosos de la limpieza con carbón rechazan las minas abandonadas: impacto ambiental y evaluación de riesgosArtículo de revistahttp://purl.org/coar/resource_type/c_6501http://purl.org/coar/resource_type/c_2df8fbb1Textinfo:eu-repo/semantics/articlehttp://purl.org/redcol/resource_type/ARTinfo:eu-repo/semantics/acceptedVersionPublicationORIGINALNanominerals and potentially hazardous elements from coal.pdfNanominerals and potentially hazardous elements from coal.pdfapplication/pdf182179https://repositorio.cuc.edu.co/bitstreams/6ae83d94-3fc4-4eb1-bf4e-a60f32d9d6a2/downloadda15f04163390828edc62f0f62084757MD51CC-LICENSElicense_rdflicense_rdfapplication/rdf+xml;
