“…375 of 2006 provides that the maximum total content of As, Cu and Zn in sanitary sewage sludge is 41; 1,500 and 2,800 mg kg -1 , respectively (Brasil, 2006), these limits much higher than those found in sanitary sewage sludge used in this study (Table 2). Nascimento et al (2014) also found lower total contents of Cd, Cr, Cu, Ni, Pb and Zn in relation to the legislation for sanitary sewage sludge, under different stabilization processes, to be used in agricultural cultivation areas.…”

This study aimed to evaluate the total contents of As, Cu and Zn in the profile of a Haplic Cambisol cultivated with crambe and corn and fertilized with sanitary sewage sludge and to compare them with those obtained in other forms of fertilization, as well as the content of metals in the grain of these crops. Two experiments were carried out in the field, one with maize cultivation and another with crambe, both were delineated as randomized blocks with four treatments and six replicates, which were: without fertilization, fertilization with sewage sludge dewatered and dried in the sun, with dry sewage sludge and with mineral fertilizers. At the end of the experiments soil samples were collected at 15, 50, 100, 150 and 200 cm depth for analysis of the total contents of As, Cu and Zn, as well as the grain of the crops. No differences were observed among the treatments. The total contents of As, Cu and Zn in the soil in both experiments and in the corn grains are below the limits of prevention and the maximum limit in grains established by the Brazilian resolutions. In relation to depth, the metal contents in the samples collected from the soil submitted to the fertilization treatments were similar to those quantified in the plots that did not received fertilization, but there was accumulation of Cu and Zn in the upper layers of the soil that received fertilization.

“…The contents of the elements Fe, Zn, Cu, Mn, Al and Se decreased with the DE addition to the vermicomposting process (Table 2), since this residue has low contents of these elements in its composition (Table 1) Nascimento et al (2014) in vermicompost of SS and plant residues, which were equal to 374 and 71 mg kg -1 , respectively. For Fe and Mn, Hashemimajd & Jamaati-e-Somarin (2011) reported contents ranging from 3,000 to 6,000 mg kg -1 and from 225 to 300 mg kg -1 , respectively, in vermicompost of SS and plant residues.…”

The pursuit for waste recovery has been the best way to contribute to environmental sustainability. The mix of sewage sludge (SS) from Sewage Treatment Plant with diatomaceous material containing oil (DE), used as a filter in biofuel production, can form a substrate rich in minerals and organic matter through vermicomposting. Therefore, this study aimed to produce vermicompost using worms, Eisenia foetida, from a pre-compost (PC) of sewage sludge and garden pruning residues mixed with different proportions of DE in relation to PC: 0; 7.53; 15.06; 22.59; and 30.12% v/v. The design was randomized complete blocks with five treatment replicates. The chemical characteristics of the vermicompost were analyzed after a period of four months. The proportion of up to 30.12% v/v of DE met the criteria established for agriculture uses, registration and marketing of the product as organic compost in accordance with the Normative Instructions SDA 27/2006 and 25/2009 from the Ministry of Agriculture.

“…There was a trend towards bioindicator higher dry matter yield from the increase of the biosolid dose. This may be justified by the fact that biosolids appear as a source of plant essential nutrients (Nascimento et al, 2014). Depth increase in the test column also provided higher dry matter yield ( Figure 1D).…”

Biosolids in Leaching of Herbicides Mimicking Auxin in Tropical Soils

-Biosolids are residues from the treatment of urban fluids used as a source of nutrients for agricultural and forestry crops. The organic matter contained in this residue and its chemical characteristics may interfere with the behavior of herbicides in the soil. The objective of this study was to evaluate the influence of biosolids on the potential for leaching herbicides mimicking auxin. Two simultaneous experiments were performed: a leaching test of picloram + 2.4-D in soil column with addition of thermally treated biosolids or solarized biosolids and another one to evaluate the effect of leachate application from the leaching tests under inert material. Each type of biosolid was incorporated in sandy soil in the proportions of 0%, 50%, 100% and 150% of the maximum recommended dose for subsurface fertilization for eucalyptus. The soil was conditioned in PVC columns and the herbicide columns based on picloram + 2.4-D (Turuna® Commercial Formulation), corresponding to 240 g L -1 of 2.4-D + 64 g L -1 of picloram at a dose of 3.5 L ha -1 of the commercial product. The columns were submitted to rain simulation and the resulting leachate was collected, followed by its application in sand-filled pots. The Cucumis sativus was sown along the profile of the soil columns and in the pots. The incorporation of the biosolid, independently of the type and dose tested did not interfere in the leaching potential of picloram + 2.4-D. Symptoms of intoxication were observed along all soil columns and pots. Therefore this residue is not very effective for the resolution of environmental problems caused by the leaching of auxin-mimicking herbicides in the soil. Keywords
