Previous issue date: 2017-03-31 / As Unidades de Terminais Aquavi?rios tem como fun??o principal receber, armazenar e distribuir petr?leo, derivados e combust?veis renov?veis l?quidos, garantindo o abastecimento dos mercados nacional e internacional. A grande movimenta??o log?stica gerada pela explora??o, beneficiamento, armazenagem, transporte e comercializa??o do petr?leo e seus derivados vem gerando preocupa??es relacionadas ? sua potencialidade de contamina??o do ambiente. Por causa dos in?meros acidentes com derramamento de combust?veis, os quais ocasionam contamina??es de solos e ?guas por hidrocarbonetos derivados de petr?leo, torna as pesquisas neste contexto um desafio para os profissionais que atuam na ?rea, em fun??o da complexidade de intera??es que ocorrem no solo e na ?gua. O Terminal, objeto de estudo, est? localizado na cidade de Natal-RN e ocupa uma ?rea de 110.000 m2. O estudo visa avaliar a contamina??o do solo e ?gua subterr?nea por derivados de petr?leo na bacia do tanque 1430-04, caracterizando a presen?a de subst?ncias com potencial de contamina??o atrav?s de dados obtidos pela coleta de amostras do solo e ?gua distribu?das para an?lise dos par?metros TPH fracionado, BTEX, VOC, SVOC e Metais. Como tamb?m, a an?lise dos par?metros f?sicos do solo (granulometria, porosidade total e efetiva, densidade de part?culas e total do solo, umidade natural) e fra??o de carbono org?nico. As an?lises qu?micas das amostras de solo n?o apresentaram concentra??es dos par?metros analisados (TPH, BTEX, VOC, SVOC e Metais). Nas amostras de ?gua subterr?neas foram detectadas concentra??es de benzeno, al?m de xilenos e TPH. Para os metais, foram detectados concentra??es de chumbo, al?m do ferro. J? para os metais dissolvidos apenas o chumbo apresentou concentra??es acima dos valores de investiga??o. Todos os resultados das an?lises qu?micas foram comparados com os valores da Resolu??o 420 do CONAMA de 2009. / The Aquavi?rios Terminal Unit's main function is to receive, store and distribute oil, oil products and liquid renewable fuels, ensuring the supply of domestic and international markets. The great logistic movement generated by the exploration, processing, storage, transportation and commercialization of oil and its derivatives has generated worries related to its potential contamination of the environment. Because of the numerous accidents with fuel spills, which cause contamination of soils and waters by oil-derived hydrocarbons, research in this context makes it a challenge for professionals working in the area, due to the complexity of interactions occurring in the soil and in the water. The Terminal, object of study, is located in the city of Natal-RN and occupies an area of 110,000 m2. The aim of this study is to evaluate soil and groundwater contamination by petroleum by-products in the 1430-04 basin, characterizing the presence of substances with potential contamination in soil and groundwater through the collection of soil and water samples for the analysis of TPH fractional parameters, BTEX, VOC, SVOC and metals. As well as the analysis of soil physical parameters (particle size, total and effective porosity, particle density and total soil, natural moisture) and organic carbon fraction. The chemical analyzes of soil samples did not present concentrations of the analyzed parameters (TPH, BTEX, VOC, SVOC and metals). Concentrations of benzene were detected in the groundwater samples, in addition to xylenes and TPH. For metals, concentrations of lead were detected in addition to iron. For dissolved metals, only lead had concentrations above the values investigated. All results of the chemical analyzes were compared with the values of CONAMA Resolution 420/2009.
