Artigo IPEN-doc 26462 Long-term leaching of As, Cd, Mo, Pb, and Zn from coal fly ash in column test2019 - LANGE, C.N.; FLUES, M.; HIROMOTO, G.; BOSCOV, M.E.G.; CAMARGO, I.M.C.Globally, millions of tons of coal fly ash (CFA) are generated per year, and the majority of this material is usually stored in stock piles or landfills, and in a long-term, it can be an environmental hazard if rainwater infiltrates the ashes. Long-term leaching studies of Brazilian ashes are scarce. The purpose of this study was to evaluate arsenic, cadmium, molybdenum, lead, and zinc leaching behavior from a Brazilian CFA by a column experiment designed to simulate field conditions: slightly acid rain considering seasonality of precipitation and temperature for a long-term leaching period (336 days). All elements were leached from CFA, except lead. Elements leaching behavior was influenced by leaching time, leaching volume, and temperature. Higher leachability of As and Cd from CFA during warm and wet season was observed. Results indicate a potential risk to soil and groundwater, since ashes are usually stored in uncovered fields on power plants vicinity.Artigo IPEN-doc 14197 Speciation of sup(238)U, sup(226)Ra, sup(210)Pb, sup(228)Ra, and stable Pb in the soil near an exhaust ventilating shaft of a uranium mine1995 - BUNZL, K.; KRETNER, R.; SCHRAMEL, P.; SZELES, M.; WINKLER, R.Artigo IPEN-doc 12840 Water soluble ions and trace metals in airbone particles over urban areas of the state of Sao Paulo, Brazil: influences of local sources and long range transport2007 - VASCONCELLOS, PEROLA C.; BALASUBRAMANIAN, RAJASEKHAR; BRUNS, ROY E.; CCOYLLO, ODON S.; ANDRADE, MARIA F.; FLUES, MARLENEArtigo IPEN-doc 09859 Soil characterization in a subtropical forest crossed by highways (Cantareira State Park, SP, Brazil)2004 - FLUES, M.; SATO, I.M.; COTRIM, M.B.; SALVADOR, V.L.; RANZANI, A.C.; VALLILO, M.I.; OLIVEIRA, E.Artigo IPEN-doc 12911 An improved method for determination of uranium isotopic composition in urine by alpha spectrometry1994 - DUARTE, CELINA L.; SZELES, MARLENE S.M.F.Artigo IPEN-doc 09073 Evaluation of the rainwater acidity of a rural region due to a coal-fired power plant in Brazil2002 - FLUES, M.S.M.; HAMA, P.; LEMES, M.J.L.; DANTAS, E.S.K.; FORNARO, A.Artigo IPEN-doc 09097 The influence of a coal-fired power plant operation on radionuclide concentrations in soil2002 - FLUES, M.S.M.; MORAES, V.; MAZZILLI, B.P.Artigo IPEN-doc 16461 Avaliação do nível da vulnerabilidade do solo devido à presença de termelétrica a carvão (Figueira, PR-Brasil)2003 - FLUES, MARLENE; HAMA, PATRICIA; FORNARO, ADALGIZAArtigo IPEN-doc 09853 Estabilizacao de solo contaminado com zinco usando zeolitas sinterizadas a partir de cinzas de carvao2004 - FUNGARO, D.A.; FLUES, M.S.M.; CELEBRONI, A.P.Artigo IPEN-doc 11735 Radioactivity of coal and ashes from Figueira coal power plant in Brazil2006 - FLUES, M.; CAMARGO, IARA M.C.; SILVA, P.S.C.; MAZZILLI, B.P.
