“…A concentration below the maximum limits allowed does not necessarily eliminate the risks of contamination since successive applications may lead to the accumulation of these metals in the agricultural soil (FJÄLLBORG et al, 2005). Andrade et al (2014) analyzed the heavy metal contents in two corn-cultivated Oxisols, which received thirteen annual applications of 5, 10, and 20 t ha −1 of sewage sludge, and found an increased content of heavy metals in the soil surface layer. Despite the fact that the contents were below the values determined by CONAMA Resolution No.…”

Sanitary sewage collection and treatment is a serious environmental problem in Brazilian cities, as well as the destination of solid waste resulting from this process, i.e. the sewage sludge, a substance rich in organic matter and nutrients, which is normally discarded in landfills. The aim of this study was to characterize the sewage sludge generated in four treatment stations in Rio de Janeiro State, Brazil and check if they meet the legal criteria of the National Environment Council (CONAMA), Resolution No. 375/2006. It also focused on analyzing the perspectives for its agricultural recycling based on the potential demand for main agricultural crops grown in Rio de Janeiro State. Samples from eight sewage sludge lots from four treatment stations located in the metropolitan area of Rio de Janeiro were analyzed. These stations receive and treat only domestic sewage by activated sludge system. For chemical and biological characterization of these lots, representative samples were collected and analyzed according to parameters of CONAMA Resolution No. 375/2006. In order to analyze the perspectives of agricultural recycling of sewage sludge in Rio de Janeiro State, 10 crops with the largest cultivated area in the state were surveyed and analyzed which of them are apt to receive sewage sludge as fertilizer and/or soil amendment. To determine the potential demand for sewage sludge in agriculture, the area occupied by these crops were multiplied by each fertilizer recommendation considering the sewage sludge as fertilizer. The analyzed sludge presented a high content of nutrients and organic matter and was included in the parameters of heavy metals, pathogenic agents, and bacteriological indicators stipulated by CONAMA Resolution No. 375/2006. The agricultural panorama of Rio de Janeiro State is favorable for agricultural recycling of sewage sludge since there is a great potential demand for this residue and, among the 10 agricultural crops with the largest cultivated area in the state, sludge can be used as fertilizer or soil amendment in eight of them. The implementation of a State Sewage Sludge Recycling Program could dispose of this material in a more sustainable way, as well as improve the quality of agricultural soils and reduce costs with chemical fertilizers, bringing positive results for sanitation companies and producers.

Objetivou-se com este trabalho caracterizar o lodo de esgoto gerado em quatro estações de tratamento do estado do Rio de Janeiro e verificar se os mesmos atendem aos critérios legais presentes na resolução CONAMA n°375/2006.

“…In Brazil, the application of biosolids from a sewage treatment station on red Latosol (Oxisol) for 12 consecutive years resulted in a significant accumulation of HMs, such as As, Ba, Cd, Cr, Cu, Hg, Ni, Pb and Zn. Moreover, in only a little more than a decade, the values of Cd (1.98 mg dm À3 ), Cr (162 mg dm À3 ), Cu (147 mg dm À3 ) and Ni (31 mg dm À3 ) exceeded the prevention value established by Resolution 420 (CONAMA 2009), a law that establishes the prevention values for Brazilian soils (Andrade et al 2014).…”

“…In tropical agricultural soils, the accumulation of HMs mainly occurs through the application of pesticides, inorganic fertilisers, biosolids and organic fertilisers, such as pig manure and poultry litter (Fontes and Gomes 2003;Andrade et al 2014;Mishra et al 2009;Khairiah et al 2006;Uchimiya et al 2012;Huang and Jin 2008). Among inorganic fertilisers, phosphate fertilisers are considered the major source of HMs in agricultural soils (Kabata-Pendias 2011; Atafar et al 2010;Huang and Jin 2008;Thawornchaisit and Polprasert 2009).…”

“…In general, the prolonged use of phosphate fertilisers, biosolids and pesticides in tropical soils has substantially increased the natural levels of Cd, Cr, Cu, Pb and Zn in soils and crops, whereas other metals, such as As, Ba, Hg, Mo, Ni, Mn and Fe, are less reported and studied, most likely due to less significant changes or more regional accumulations (dos Anjos and Mattiazzo 2000; Appel and Ma 2002;Cai et al 2007;Atafar et al 2010;Camilotti et al 2012;Andrade et al 2014;Araújo et al 2014;Doelsch et al 2006;Fernandes et al 2007a;Fontes and Gomes 2003;Gonçalves Júnior et al 2000;Huang and Jin 2008;Khairiah et al 2006;Maftoun et al 2005;Mishra et al 2009;Nogueira et al 2013;Parkpain et al 2000;Parkpian et al 2003;Sharma et al 2009;Soumare et al 2003;Udom et al 2004).

“…The final disposition of sewage sludge also offers a risk to the environment, plant, animal and human health because it contains trace elements (Andrade et al [1]) and toxic organic substances and pathogenic organisms (Sidihu and Toze [2]) in different concentrations and combinations. It also attracts insects and other disease transmitters.…”

Sewage sludge (SS), a residue from wastewater treatment can be a hazard to the environment because it may contain trace elements and other toxic substances. But it is also rich in organic matter and plant nutrients so that an attractive destination for the residue is its use in agriculture as fertilizer and soil conditioner. The aim of this work was to evaluate the effect of doses of SS from the textile industry on sorghum plant growth. The experiment was carried out under greenhouse conditions using typic Haplorthox soil occurring at Jaboticabal, SP, Brazil. The experiment design was totally randomized with 7 treatments (absolute control, without fertilization and SS, mineral control, with mineral fertilization based on soil analysis, 7, 14, 21, 28 and 35 t ha-1 SS, dry basis) in 3 replications and sorghum as the test plant. At the end of the plant cycle, plant dry matter and grain production were estimated, and soil samples were analyzed for soil chemical fertility. Textile sewage sludge improved soil fertility, except in relation to K and Mg, plant dry matter and grain production. It also caused symptoms of K deficiency and other symptoms of unknown origin. The SS rates caused the same grain production and the highest doses caused delay in the panicle emission.
