Impacts of Sewage Sludge in Tropical Soil: A Case Study in Brazil

Abstract: A long-term assay was conducted to evaluate the environmental impacts of agriculture use of sewage sludge on a tropical soil. This paper describes and discusses the results obtained by applying a interdisciplinary approach and the valuable insights gained. Experimental site was located in Jaguariúna (SP, Brazil). Multiyear comparison was developed with the application of sewage sludge obtained from wastewater treatment plants at Barueri (domestic and industrial sewage) and Franca (domestic sewage), São Paulo S… Show more

“…According to Bittencourt et al (2014), the main reason for the reduced efficiency of alkalinized sewage sludge as a K source is its low content in the sludge (the lowest of the macronutrients), which occurs because of the loss of this nutrient via effluents during the treatment process. Other studies likewise reported little influence on the soil K + interpretation class for non-alkalinized sewage sludge (Bettiol;Ghini, 2011;Carmo;Lima;Silva, 2016). For practical application, however, the K supply available to cultivated plants, from other sources of this nutrient, must be determined.…”

“…Por outro lado, o uso incorreto deste resíduo pode contaminar o solo, as plantas e as águas superficiais e subterrâneas com nitratos, fosfatos, metais pesados e outros poluentes presentes (Bettiol & Ghini 2011). Estudos recentes não constataram aumento significativo de metais pesados em grãos de milho, após aplicações de lodo de esgoto (Trannin et al 2005, Merlino et al 2010.…”

“…Researches about sewage sludge disposal in soil are focused on its effects on soil fertility, plant development, and contamination by heavy metals and organic compounds [24]. However, few studies have been conducted to evaluate the toxic, genotoxic, and mutagenic potentials of the sewage sludge disposal on exposed plants and animals.…”
