| Resumo: O lodo pode fornecer às plantas, em quantidades satisfatórias, com exceção do potássio, todos os nutrientes essenciais para as culturas. A composição química do lodo é de suma importância na recomendação da quantidade a ser aplicada no solo. As recomendações são normalmente baseadas no teor de nitrogênio levando-se em consideração as concentrações de metais pesados presentes na massa de lodo, além da presença de patógenos. Assim, o conhecimento da taxa de mineralização do N orgânico é um dos principais fatores que determinam a quantidade de lodo a ser aplicada no solo. Apesar das vantagens do uso de lodo de esgoto para recuperar áreas degradadas, como apontado pela avaliação de outras variáveis neste estudo, deve ser salientado o inconveniente... |

| ABSTRACT: With the increase of the population density in the cities, a great amount of residual waters passed to be generated. The usual practical ones of disposal of the sewage sludge, as the "sanitary and controlled embankment" or the "oustings the opened sky", are alternative of cost to each day more raised or have potential to produce impacts ambient undesirable, beyond constituting, frequently, in focus of problems of public health, through contamination of superficial and underground waters, and of the proliferation of animals and insects vectors of illnesses. Processes come being perfected to get a sewage sludge with biological, physical and chemical characteristics desirable for its use in agricultural areas, as biosolid. Data on the effect of its... |

| In this paper, we review those data which have recently become available for brominated flame retardants (particularly the brominated diphenyl ethers (BDEs) and hexabromocyclododecane (HBCD)) in samples from the European environment. Environmental compartments studied comprise the atmosphere, sediments and soils. sewage sludges. and a variety of biological samples and food chains. This is currently a very active research area, and we cite over 70 studies reported in the literature during 2003-04. Findings include that the input of BDEs (especially BDE209) to the Baltic Sea by atmospheric deposition now exceeds that of PCBs by a factor of almost 40 times. Sewage sludge samples from both industrial and background locations show concentrations of BDEs. HBCD... |

| Biosolids have been considered satisfactory to supply crops and plant nutrients. The ideal biosolids application rate should result in high crop yields and nutrient uptake, and leave low concentrations of nutrients in soils to avoid environmental problems. The objective of this study was to estimate the capacity of five biosolids to supply N and P to ryegrass (Lolium perenne) after a single application of either fertilizers or biosolids to a Spodosol and an Oxisol. Results showed that 6% - 36% of N and 3% - 7% of P applied as biosolids were recovered in plants grown on the Spodosol, while the range on the Oxisol was 26%-75% for N and 1.2%-3.7% for phosphorus. Biosolids' efficiency on supplying N and P to plants was similar to fertilizer on the Spodosol,... |

| ABSTRACT The composition of organic waste (OW) and its effect on soil processes may change soil fertility and electrical conductivity (EC). The side effects of waste use in crop fertilization are poorly understood for Brazilian soils. This study examined the effect of the addition of 15 different organic wastes to Oxisols and a Neosol on pH, base saturation, EC, cation exchange capacity (CEC at pH 7), and the availability of Al, macro (P, K, Ca2+, Mg2+ and S) and micronutrients (B, Fe2+, Mn2+, Cu2+ and Zn2+). Soil samples (150 g) were treated with chicken, pig, horse, cattle, and quail manures, sewage sludge 1 and 2, eucalyptus sawdust, plant substrate, coconut fiber, pine bark, coffee husk, peat, limed compost, and biochar. Wastes were added considering a... |

| ABSTRACT Biosolids have been produced by various stabilization processes of sewage sludge, but little attention has been given to the effects of such treatments on their effectiveness to supply nitrogen for plant growth. Here, we investigated these effects by cultivating Lolium perenne (ryegrass) in two Australian soils, a sandy Spodosol and a clayey Oxisol. Biosolids stabilized by either aerobic digestion, composting, CaO-liming, 250 oC heat-drying or solar irradiation of domestic sewage sludge were applied to soils at 10 increasing rates (0.25-8.0 dry Mg ha-1), and chemically fertilized soils were used as reference. Results showed that the stabilization processes affected biosolids-N agronomic rates and effectiveness to yield plant biomass, which was a... |

| There are currently many devices and techniques to quantify trace elements (TEs) in various matrices, but their efficacy is dependent on the digestion methods (DMs) employed in the opening of such matrices which, although "organic", present inorganic components which are difficult to solubilize. This study was carried out to evaluate the recovery of Fe, Zn, Cr, Ni, Cd and Pb contents in samples of composts and cattle, horse, chicken, quail, and swine manures, as well as in sewage sludges and peat. The DMs employed were acid digestion in microwaves with HNO3 (EPA 3051A); nitric-perchloric digestion with HNO3 + HClO4 in a digestion block (NP); dry ashing in a muffle furnace and solubilization of residual ash in nitric acid (MDA); digestion by using aqua... |

| ABSTRACT This study aimed to verify the potential of urban solid wastes as substrate for production of seedlings of Lafoensia pacari. Five treatments were tested, four with solid wastes and one standard substrate, namely: sewage sludge from Alegria Wastewater Treatment Plant (WTP); sewage sludge from Ilha do Governador WTP; sewage sludge from Sarapuí WTP; domestic garbage compost (Fertlurb); and a commercial substrate made of biostabilized pine bark (standard substrate). The wastes received 20% (in volume) of shredded coconut fiber. At 105 days after sowing, the seedlings were evaluated for different quality parameters. Seedlings produced with Sarapuí WTP sewage sludge showed the best results in all the parameters, followed by seedlings produced with... |

| ABSTRACT One of the major limitations of sewage sludge agricultural use is the presence of chlorobenzenes (CBs), which are toxic to the environment. The use of techniques of sewage sludge phytoremediation can be an important alternative for the degradation of these substances in the waste. The aim of this study was to evaluate the effect of Pennisetum purpureum cultivation time on the reduction of the concentrations of 1,4-CB and 1,3,5-CB in sewage sludge. The experiment was conducted in a greenhouse, using a randomized block design. The treatments consisted of five periods of Poaceae cultivation in sewage sludge plots (30, 60, 90, 120 and 150 days) and a control (sludge plots not cultivated). At 150 days, the control, in the layer of 0-20 cm, showed... |

| ABSTRACT In order to reduce the effect of heavy metals on the biosolid, it is necessary to promote its phytoremediation. It is important to know the total content and chemical forms of these elements in the residue for analyzing its behavior and potential toxicity. Thus, the aim of this study was to evaluate the fractionation and behavior of Cu and Zn in biosolid cultivated with Pennisetum purpureum in different periods. The experiment was carried out using a randomized complete block design. The treatments, with five replicates, corresponded to Pennisetum purpureum cultivation in biosolid for 30, 60, 90, 120 and 150 days after planting. The total contents of Cu and Zn in the biosolid remained below the critical limits established by the CONAMA Resolution... |

| The sewage sludge (SS) represents a source of organic matter although its increasing accumulation need a suitable environmental treatment. Our study analyzed the effect of the interaction between sewage sludge (doses 0, 2, 4, 6 and 8 g per 100 g of soil) and Eucalyptus globulus nursery seedlings inoculated with arbuscular mycorrhizal (AM) fungi as a fertilizers alternative and evaluate its effect on some soil enzyme activities. The seedlings were inoculated with Glomus claroideum, Glomus viscosum, Glomus intraradices and Glomus constrictum, establishing a uninoculated control. The sewage sludge application increased the shoot dry weight and the inoculation with G. viscosum was more effective at 6 g of SS in 100 g soil. The root colonization and succinate... |

| Saline soil was amended with 13.3 and 26.6 g kg-1 of Municipal Solid Waste (MSW) compost or sewage sludge, and arylsulphatase (ARY), phosphatase (PHO), dehydrogenase (DEH), (β-glucosidase ((β-GLU), urease (URE) and catalase (CAT) activities as well as physical-chemical properties were determined after 70 day of incubation under laboratory conditions. MSW compost and sewage sludge significantly improved soil physical-chemical properties, especially carbon and nitrogen contents. Accordingly, overall enzyme activities were substantially promoted in presence of both amendments and the higher increases were measured at 13.3 g kg-1 of MSW compost (increases by 107%, 43%, 20%, 11%, and 148% for, DEH, (3-GLU, PHO, URE, and CAT, respectively).... |
