Resumo: | Contamination of soils and groundwater by volatile organic compounds promotes numerous environmental and health problems. Soil contaminants are fuel leaks resulting from accidents during transportation or even from inadequate infrastructure in buried tanks. In this context gasoline contamination is the most frequent and results in the contamination by aromatic hydrocarbons (BTEX: Benzene, Toluene, Ethyl-benzene and Xylenes); Such compounds are harmful to human health and the environment. With the expansion of the distribution network in the country and the urban reorganization, a significant increase of areas of contamination risk is observed, especially those already existing. The sample methodologies recommended by the official bodies can be questioned, and during the processes of collection and even execution of the analyzes. As a rule, the applied sampling reduces the collection of soil samples on predetermined length by discrete mathematical modeling. The objective of this work is to propose and analyze the appropriate sampling procedure in order to generate maps of contamination in impacted regions in order to evaluate the initial real size of the contamination detected by BTEX and to propose a sampling procedure that takes into account the Influencing factors such as volatility, soil permeability, temperature and expansion of the contaminated spot among others, in order to allow better evaluation of the soil situation. Soil analyzes obtained in a specific case study in which the presence of BTEX shows a reduction of more than 70% in relation to the methodology certified by CETESB, Gas Chromatography, Mass spectroscopy, The Post in question was evaluated in 5 times and the results Obtained point to contamination in 5 of the occasions the tests are inconclusive because in 3 times they gave negative and others (positive) for BTEX. This reinforces the need to develop more accurate and accurate conceptual models that can actually assure the presence, movement or even storage of the BTEX contaminant |

Os responsáveis pela contaminação do solo são os vazamentos de combustíveis resultantes de acidentes durante o transporte ou mesmo pela infraestrutura inadequada em tanques enterrados. Neste contexto a contaminação por gasolina é a mais frequente e resulta na contaminação por hidrocarbonetos aromáticos (BTEX: Benzeno, Tolueno, Etil-benzeno e os Xilenos); tais compostos são danosos à saúde humana e ao meio ambiente. Com a expansão das redes de postos de distribuição no país e da reorganização urbana, é observado um aumento significativo de áreas de risco de contaminação em especial aos já existentes. As metodologias amostrais recomendadas pelos órgãos oficiais podem ser questionadas, e durante os processos de coleta e mesmo posterior execução das análises. Por via de regra, a amostragem aplicada reduz-se a coleta de amostras de solo sobre metragem pré-determinada por modelagem matemática discreta. Este trabalho tem como objetivo, propor e analisar o procedimento de coleta amostral adequados, de modo a gerar mapas de contaminação em regiões impactadas de modo a avaliar a dimensão inicial real da contaminação por BTEX detectados e assim propor um procedimento amostral que leve em consideração os fatores influenciadores tais como, volatilidade, permeabilidade de solo, temperatura e expansão da mancha contaminada entre outros, de modo a permitir melhor avaliação da situação do solo. Análises de solo obtidas em estudo de caso específico no qual demonstram a presença de BTEX redução de mais de 70 % em relação segundo a metodologia certificada pela CETESB, Cromatografia Gasosa, Espectroscopia de massas, O Posto em questão foi avaliado em 5 vezes sendo que os resultados obtidos apontam para contaminação em 5 das ocasiões as contraprovas são inconclusivas pois em 3 vezes deram negativas e outras (positivas) para BTEX. Isto consolida a necessidade do desenvolvimento de modelos conceituais mais adequados e precisos, que possam assegurar realmente a presença, a movimentação ou mesmo o armazenamento do contaminante BTEXSubmitted by Laudeceia Machado (laudeceia.machado@usc.br) on 2017-04-11T00:56:54Z No. of bitstreams: 1 Analise critica de metodologia de investigacao de areas contaminadas - avaliacao preliminar...

Contamination of soils and groundwater by volatile organic compounds promotes numerous environmental and health problems. Soil contaminants are fuel leaks resulting from accidents during transportation or even from inadequate infrastructure in buried tanks. In this context gasoline contamination is the most frequent and results in the contamination by aromatic hydrocarbons (BTEX: Benzene, Toluene, Ethyl-benzene and Xylenes); Such compounds are harmful to human health and the environment. With the expansion of the distribution network in the country and the urban reorganization, a significant increase of areas of contamination risk is observed, especially those already existing. The sample methodologies recommended by the official bodies can be questioned, and during the processes of collection and even execution of the analyzes. As a rule, the applied sampling reduces the collection of soil samples on predetermined length by discrete mathematical modeling. The objective of this work is to propose and analyze the appropriate sampling procedure in order to generate maps of contamination in impacted regions in order to evaluate the initial real size of the contamination detected by BTEX and to propose a sampling procedure that takes into account the Influencing factors such as volatility, soil permeability, temperature and expansion of the contaminated spot among others, in order to allow better evaluation of the soil situation. Soil analyzes obtained in a specific case study in which the presence of BTEX shows a reduction of more than 70% in relation to the methodology certified by CETESB, Gas Chromatography, Mass spectroscopy, The Post in question was evaluated in 5 times and the results Obtained point to contamination in 5 of the occasions the tests are inconclusive because in 3 times they gave negative and others (positive) for BTEX. This reinforces the need to develop more accurate and accurate conceptual models that can actually assure the presence, movement or even storage of the BTEX contaminant |
