Resumo: | Contamination of terrestrial environments by oil spills is a recurrent fact in the world, which creates biological risks to human´s and ecosystem´s health. The studies about oil spill aim to evaluate the toxicity and changes in the chemical composition of soils and waters, in a field of potential interest to the scientific community. In this context, the present work evaluated the changes in the chemical composition of crude oil fractions after the simulation of a spill in soil and sand, with emphasis on an immediate temporal investigation. Were used samples of medium and heavy oils from the Sergipe-Alagoas basin, soil from the rural area of São Cristóvão-SE and sand from Atalaia´s beach in Aracaju- SE. The simulations were performed with a 40:1 (m/m) mixture of terrestrial:oil with direct influence of a 60 W lamp with cycles of 12 hours per day. The aliquots of soil and sand were taken from the system at times of 1, 12, 24, 48 and 72 h, then were extracted with n-hexane/dichloromethane/methanol (7:2:1) and submitted to SARA fractionation in micro column and GC-FID analysis. SARA gravimetric data showed that the saturated fraction decreased 14.2 % and 3.7 % for the medium oil that interacted with soil and sand respectively. On the other hand, the saturated fraction of heavy oil decreased 16.8% and 14. 7 % when it interacted with soil and sand respectively. It was highlighted the evaporation process in the soil; while the GC-FID chromatographic profiles demonstrated the disappearance from n-C12 until n-C14 compounds, besides a decrease of more than 50% in n-C15 and n-C16 n-alkanes. The absolute aromatic and resins fractions remained constant during the exposure time (1 h to 72 h) for both environments and oils. Analysis of resins fraction performed by Orbitrap-MS, have shown changes in the mass spectra profile during the soil exposure process, with N1, O1,ad O3 species showing the greatest changes in the relative intensity in ESI(+) mode, O2, N1, O3 and O1 for ESI(-). Changes in polar oil compounds will depend on the extent of the time they interact with soil and sand, taking into account aspects such as the nature of the soil and components in it as the organic matter. |

Os estudos sobre derrames de petróleo visam avaliar a toxicidade e mudanças na composição química de solos e águas, em um campo de potencial interesse para a comunidade científica. Neste contexto, o presente trabalho avaliou as mudanças na composição química das frações de petróleo bruto após as simulações de derrames em solo e areia, com ênfase em uma investigação temporal imediata. Foram utilizadas amostras de óleos, mediano e pesado, da bacia de Sergipe-Alagoas, areia da praia de Aracaju-SE e solo da área rural de São Cristóvão-SE. As simulações foram realizadas com misturas 40:1 (m/m) de ambiente terrestre:óleo com incidência direta de uma lâmpada de 60 W operando em ciclos de 12 horas por dia. As amostragens do solo e areia foram realizadas com 1, 12, 24, 48 e 72 horas. As amostras foram extraídas com n-hexano/diclorometano/metanol (7:2:1) e submetidas ao fracionamento SARA em microcoluna, acompanhada de análises por GC-FID. A classificação SARA mostraram que a fração de saturados diminui 14,2 % e 3,7 % para o óleo mediano que interagiu com solo e areia respectivamente. A fração de saturados do óleo pesado diminui 16,8 % e 14,7 % quando interagiu com solo e areia respectivamente. Foi destacado o processo de evaporação no solo, enquanto os perfis cromatográficos demonstraram o desaparecimento dos compostos desde n-C12 até n-C14, além da diminuição de mais de 50 % nos nalcanos n-C15 e n-C16. A fração absoluta de aromáticos e as resinas permaneceram constantes durante o tempo de exposição (1 a 72 h) para os dois ambientes e os dois óleos estudados. A análise das frações de resinas realizadas por Orbitrap-MS mostraram que o perfil dos espectros de massas mudam ao longo do processo de exposição ao solo e areia, sendo as espécies N1, O1, e O3 as que apresentaram maior mudanças na abundância relativa no modo ESI(+), e as espécies O2, N1, O3 e O1 no ESI(-). As mudanças nos compostos polares do petróleo, apresentaram relação com a medida do tempo que interagirem com o solo e a areia, tendo relevância alguns aspectos, como a natureza do solo e os componentes presentes nele, como a matéria orgânica.Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPESSão Cristóvão, SEporQuímicaPetróleoSolosPoluição por óleoAreiaCompostos saturados do óleoResinasSaturados, aromáticos, resinas e asfaltenos (SARA)Espectrometria de massas com transformada de Fourier (FTMS)Crude oilSoilSandSaturatesResinsFourier Transform - Mass Spectrometry (FTMS)CIENCIAS EXATAS E DA TERRA::QUIMICAAvaliação da alteração molecular na composição química de petróleo nos estágios iniciais de contato com ambientes terrestresEvaluation of the changes in the molecular composition of crude oil in the initial stages of contact with terrestrial environmentsinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisPós-Graduação em QuímicaUFSreponame:Repositório Institucional da UFSinstname:Universidade Federal de Sergipe (UFS)instacron:UFSinfo:eu-repo/semantics/openAccessTEXTJULIAN_EDUARDO_BALLEN_CASTIBLANCO.pdf.txtJULIAN_EDUARDO_BALLEN_CASTIBLANCO.pdf.txtExtracted texttext/plain160590https://ri.ufs.br/jspui/bitstream/riufs/11892/3/JULIAN_EDUARDO_BALLEN_CASTIBLANCO.pdf.txtb56ef773c504957a8e175b7e1ca64514MD53THUMBNAILJULIAN_EDUARDO_BALLEN_CASTIBLANCO.pdf.jpgJULIAN_EDUARDO_BALLEN_CASTIBLANCO.pdf.jpgGenerated Thumbnailimage/jpeg1572https://ri.ufs.br/jspui/bitstream/riufs/11892/4/JULIAN_EDUARDO_BALLEN_CASTIBLANCO.pdf.jpgaa00e5dcd60a79b57e9c7a5f59dae9d3MD54LICENSElicense.txtlicense.txttext/plain; charset=utf-81475https://ri.ufs.br/jspui/bitstream/riufs/11892/1/license.txt098cbbf65c2c15e1fb2e49c5d306a44cMD51ORIGINALJULIAN_EDUARDO_BALLEN_CASTIBLANCO.pdfJULIAN_EDUARDO_BALLEN_CASTIBLANCO.pdfapplication/pdf5262717https://ri.ufs.br/jspui/bitstream/riufs/11892/2/JULIAN_EDUARDO_BALLEN_CASTIBLANCO.pdfdedbde06b94feb6dc4ddeb8bfe63d1f7MD52riufs/118922019-09-04 18:46:28.525oai:ufs.br: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Repositório InstitucionalPUBhttps://ri.ufs.br/oai/requestrepositorio@academico.ufs.bropendoar:2019-09-04T21:46:28Repositório Institucional da UFS - Universidade Federal de Sergipe (UFS)false |

Contamination of terrestrial environments by oil spills is a recurrent fact in the world, which creates biological risks to human´s and ecosystem´s health. The studies about oil spill aim to evaluate the toxicity and changes in the chemical composition of soils and waters, in a field of potential interest to the scientific community. In this context, the present work evaluated the changes in the chemical composition of crude oil fractions after the simulation of a spill in soil and sand, with emphasis on an immediate temporal investigation. Were used samples of medium and heavy oils from the Sergipe-Alagoas basin, soil from the rural area of São Cristóvão-SE and sand from Atalaia´s beach in Aracaju- SE. The simulations were performed with a 40:1 (m/m) mixture of terrestrial:oil with direct influence of a 60 W lamp with cycles of 12 hours per day. The aliquots of soil and sand were taken from the system at times of 1, 12, 24, 48 and 72 h, then were extracted with n-hexane/dichloromethane/methanol (7:2:1) and submitted to SARA fractionation in micro column and GC-FID analysis. SARA gravimetric data showed that the saturated fraction decreased 14.2 % and 3.7 % for the medium oil that interacted with soil and sand respectively. On the other hand, the saturated fraction of heavy oil decreased 16.8% and 14. 7 % when it interacted with soil and sand respectively. It was highlighted the evaporation process in the soil; while the GC-FID chromatographic profiles demonstrated the disappearance from n-C12 until n-C14 compounds, besides a decrease of more than 50% in n-C15 and n-C16 n-alkanes. The absolute aromatic and resins fractions remained constant during the exposure time (1 h to 72 h) for both environments and oils. Analysis of resins fraction performed by Orbitrap-MS, have shown changes in the mass spectra profile during the soil exposure process, with N1, O1,ad O3 species showing the greatest changes in the relative intensity in ESI(+) mode, O2, N1, O3 and O1 for ESI(-). Changes in polar oil compounds will depend on the extent of the time they interact with soil and sand, taking into account aspects such as the nature of the soil and components in it as the organic matter. |
