RESUMO

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 objective to study the quality of the waters in Jacuba stream in Hortolândia city, residual waters and sewages, through heavy metal analysis in several samples. The samples were divided in three groups that define the study area: samples of superficial waters, collected in nine different locations, samples of inorganic and organic residual waters, without treatment and treated and, samples of sewage from state prison. The technique employed (SR-TXRF) presents some advantages in relation to the other methods, which we can emphasize the detection limit in the range of a few micrograms per liter (ppb), besides being a multi-elementary method that allows the detection of several elements in a unique measure. This technique has a high potential application in several areas, mainly in areas where it is necessary a correlation among the essential and toxicant elements...Note: The complete abstract is available with the full electronic digital thesis or dissertations
