Abstract in Portuguese
O rio Paraíba do Sul, após formar o reservatório do Funil, abastece cidades ribeirinhas e a cidade do Rio de Janeiro. A INB, uma empresa da área nuclear, está localizada na margem norte deste reservatório. Neste trabalho, Ag, Al, As, Ba, Cd, Co, Cr, Fe, Mn, Ni e Pb foram determinados por ICP OES em água e sedimentos em pontos a montante e a jusante do Funil e neste. Urânio, usando fluorimetria, também foi determinado em amostras coletadas a montante e a jusante do ponto de descarga de efluentes da INB, no ribeirão da Água Branca. O estudo não mostrou evidências que a INB está provocando impacto ambiental nesse ribeirão. As, Ni e Pb em todos os pontos de amostragem e Al, Cr e Fe na maioria desses pontos apresentaram concentrações em água acima do máximo permitido pela CONAMA 357. A maioria dos elementos apresentou concentrações nas amostras de água a montante do reservatório do Funil superiores às verficadas a jusante, para ambas as estações chuvosa e seca. Os sedimentos estão impactados por As, Cd, Cr e Pb em quase todos os pontos estudados.

Abstract in English
The Paraiba do Sul River after forming the Funil Reservoir serves as the major source of potable water for downstream cities and for the city of Rio de Janeiro. INB, a company of the nuclear area, is located in the north margin of this reservoir. In the present study, Ag, Al, As, Ba, Cd, Co, Cr, Fe, Mn, Ni and Pb were determined by ICP OES in water and sediments samples at points upstream and downstream from Funil and in this one. Uranium, using fluorimetry, was also determined in samples collected upstream and downstream from the INB effluent discharge point at the Água Branca Creek. The study did not show evidences that INB is provoking environmental impact in this creek. As, Ni and Pb in all the sampling points and Al, C and Fe in most of those points exceeded the CONAMA 357 standards for water. Most of the elements presented concentration in the water samples at the points upstream from Funil reservoir higher than those downstream, for both rainy and dry seasons. Sediments are impacted by As, Cd, Cr and Pb in almost all the studied points.
