Abstract

The application of sewage sludge on agricultural land has been considered the most suitable practice for final disposal of this organic waste daily generated in large quantities in urban areas. Within the agriculture context, the forestry sector stands out as potential candidate for the use of organic waste due to several peculiarities that have the incorporation of organic matter as a source of benefits. The sewage sludge can contain many pathogens such as helminth eggs, bacteria, viruses, protozoa and fungi, which restrict your application to soil in some countries. In Brazil, the CONAMA Resolution nº. 375 of August 30, came after several years of discussion involving acceptable risks for the use of sewage sludge in agriculture and establishes maximum limits for the concentration of pathogens in sludge to be applied in soil. The main studies involving the survival time of pathogens in soils fertilized with sewage sludge were conducted in North America and Europe, which makes the tropical regions at a disadvantage due to the lack of specific information. The present study will evaluate the persistence of viable helminth eggs, fecal coliforms, Salmonella sp and enteroviruses in soil cultivated with Eucalyptus and fertilized with sewage sludge in an area located in the city of Avaré, State of São Paulo, Brazil, following the method developed by the United States Environmental Protection Agency (USEPA) and adopted by CONAMA Resolution nº 375/2006. We also intend to compare the results obtained with the parameters established by that Resolution.
