Resumo: The use of sewage sludge in agricultural soils as a macro and micronutrient source and as a soil conditioner has been one of the alternatives for its disposal. However, sewage sludge contains trace metals, which are potential sources of pollution. The goal of this study was to evaluate the effect of sewage sludge application on surface water contamination through runoff when it was applied in a soil cultivated with corn. The effect of sludge application on the concentration and load of copper, nickel and zinc and the volume of runoff water and sediment were evaluated. The experiment was set up in plots used to study erosion losses in Campinas, Sao Paulo State, Brazil. The soil is a clayey Rhodic Hapludox. Three treatments were studied: no sewage sludge, sewage sludge to supply the N required by the crop and twice that amount, with four replications. The water and sediment lost by runoff were measured after each rainfall, and sampled for chemical analysis. The volumes of water and sediment lost by runoff decreased after sewage sludge application. The waste application increased trace metal concentration in the runoff water and sediment, especially zinc, which was present in high concentration in the sewage sludge used. Nevertheless, the load of trace metals transported from the plot was mostly dependent on the total runoff volume. Most of the Cu, Zn and Ni losses were via sediment, and occurred in a few highly erosive rainfall events in the period studied.

O uso de lodo de esgoto em solos agrícolas como fonte de macro e micronutrientes e como condicionador de solos tem sido uma das alternativas para sua disposição final. O lodo de esgoto, entretanto, contém metais que são potencialmente fonte de poluição. Estudou-se o efeito da aplicação de lodo de esgoto na contaminação de águas superficiais por meio da enxurrada proveniente de solo agrícola cultivado com milho. O efeito da aplicação do lodo na concentração e no carreamento de cobre, níquel e zinco e no volume de enxurrada e sedimentos foi avaliado. Os tratamentos foram aplicados em parcelas utilizadas para estudos de perdas por erosão em Campinas, São Paulo, Brasil. O solo era um Latossolo Vermelho férrico argiloso. Os três tratamentos foram: sem lodo, com lodo para suprir o N requerido pela cultura e duas vezes essa quantidade, com quatro repetições. A água e o sedimento perdidos pela enxurrada eram medidos na manhã seguinte de cada chuva e amostrados para análise química. Os volumes de água e de sedimentos perdidos por enxurrada diminuíram com a aplicação do lodo. A aplicação do resíduo aumentou a concentração de metais na água e no sedimento, especialmente do zinco que estava presente em alta concentração do lodo de esgoto utilizado. Entretanto, a carga de metais transportados das parcelas foi dependente principalmente do volume total de enxurrada. A maior parte das perdas de Cu, Ni e Zn foi via sedimento e ocorreu em alguns poucos eventos de alta erosividade no período de estudo. Universidade de São Paulo.
