1. BioacumulaÃÃo de Ãons de Pb+Â na macrÃfita Salvinia auriculata / Of the lead ions bioaccumulation process by living aquatic macrophytes Salvinia auriculata
In this work was carried out a study of the lead bioaccumulation process by living aquatic macrophytes Salvinia auriculata. Initially, they were performed toxicological and growing tests in order to determine the non-toxic lead concentration limits and the minimum amount of biomass for the lead uptake experiment duration. The bioaccumulation experiment was p

2. Application of electroflocculation technique for the tannery effluent treatment / AplicaÃÃo da tÃcnica de eletro-floculaÃÃo no tratamento de efluentes de curtume
In the present work has been studied the electro-flocculation efficiency on the reduction of organic and inorganic material concentrations such as Chemical Oxygen Demand (COD), turbidity, total solids and metal, mainly chromium, on an untreated tannery effluent using a pair of electrodes. For this purpose, a lab scale Electro-Flocculation (EF) reactor was co

3. Tree-rings as indicator of contamination for metals : the use of technique X-ray total reflection fluorescence with synchroton radiation (SR-TXRF) / Aneis de crescimento como indicadores de contaminação ambiental : o uso da tecnica de fluorescencia de raios X por reflexão total com radiação sincrotron (SR-TXRF)
O crescimento populacional acompanhado de um aumento dos parques industriais trouxe alguns problemas a serem enfrentados por toda a sociedade, como a emissão de poluentes. As árvores registram em seu lenho reações às variáveis ambientais podendo assimilar e armazenar contaminantes de ação antropogênica. Para identificar e quantificar tais elementos

4. Avaliação da qualidade das aguas do Ribeirão Jacuba empregando a fluorescencia de raios X por reflexão total com radiação sincroton (SR-TXRF)
The pollution of the environment became everywhere of public interest of the world. The developed countries not just come being affected for the environmental problems; the developing nations also begin to suffer the serious impacts of the pollution, what elapses of the fast economic growth associated to the exploration of natural resources. This work has as
