1. REMOVAL OF BPA FROM LANDFILL LEACHATES USING FENTON-ADSORPTION PROCESS
The objective of this investigation was to identify and quantify the presence of Bisphenol-A (BPA) in raw and treated leachates with the Fenton-adsorption process. BPA is used as a monomer to produce epoxy resins and it is a compound classified as endocrine disruptor. For this reason, it is important to quantify its presence in effluents that will be dispose

2. Biomonitors to evaluate the toxic potential of urban solid waste landfill leachate
Resumo O aumento acentuado da produção de resíduos sólidos urbanos (RSU) e o consequente acúmulo de lixiviado em aterros potencializam o risco de contaminação do meio ambiente. Biomonitores são utilizados para avaliação da toxicidade dos poluentes sobre os organismos vivos. Neste estudo, foram avaliados o potencial poluidor do lixiviado de RSU de u

3. Treatment of Sanitary Landfill Leachate by Photo-Fenton Process: Effect of the Matrix Composition
In this study it was evaluated the role of the composition of sanitary landfill leachate on the removal of dissolved organic carbon (DOC) by photo-Fenton process. The composition of the matrix (high turbidity and color, as well as presence of inorganic ions sulfate and chloride) does not reduce the efficiency of DOC removal by photo-Fenton reactions, but inf

4. IDENTIFICAÇÃO DE COMPOSTOS ORGÂNICOS EM LIXIVIADO DE ATERRO SANITÁRIO MUNICIPAL POR CROMATOGRAFIA GASOSA ACOPLADA A ESPECTROMETRIA DE MASSAS
The organic compounds present in leachate can contaminate soil, superficial and underground water, and the majority is considered harmful to the environment and human health. The objective of this study was to identify organic compounds present in landfill leachate located in Maringá-PR by gas chromatography coupled to mass spectrometry (GC-MS). The raw

5. Remoção de nitrogênio amoniacal de lixiviado de aterro de resíduos sólidos por precipitação química com formação de estruvita / Ammonium-nitrogen removal from leachate of solid waste landfill by chemical precipitation with struvite formation
Municipal solid waste landfilling is the best final disposal method due to its low operating cost and minimizing environmental impacts. As a result of degradation of the solid waste, leachate is generated and it is characterized by high concentrations of organic matter, ammonia nitrogen and inorganic salts which has high pollution potential. In this context,

6. Avaliação do tratamento de lixiviado de aterro sanitário através de processo oxidativo avançado conjugado com sistema de separação por membranas
The landfill leachate is characterized by high recalcitrant organic matter concentration, ammonia and toxic compounds. This effluent can be an environmental problem due to its high pollutant potential when it is released without treatment. Studies reported in the literature showed that biological processes are not sufficient in meeting the discharge standard

7. Lixiviado de aterros sanitários brasileiros: estudo de remoção do nitrogênio amoniacal por processo de arraste com ar ("stripping") / Sanitary landfill leachate in Brazil: evaluation of ammonia nitrogen removal by air stripping process
Sanitary landfills are considered as the most appropriate way for final disposal of municipal solid wastes in Brazil, in the technical and economical point of view. Open dumps have been progressively substituted by well engineered and operated landfills. However, landfills still present environmental risks due to the gas emission and leachate production. Gas

8. ANÁLISE QUÍMICA DO LIXIVIADO DA ÁGUA DE XISTO EM UM LATOSSOLO VERMELHO ESCURO DISTRÓFICO
Industrial processes generate a series of products, often without applicability becomes waste that contribute to pollution of soil, air and water. Some products may be reused and / or processed into raw materials for other processes. In this context, analyzed the water of oil shale (a byproduct of the process of obtaining the oil shale) using an Instrumental
