1. Soybean in succession to the residue of the sorghum/Paiaguás grass straw with Azospirillum brasilense
ABSTRACT One of the alternatives to achieve agriculture with sustainability and reduction in production costs, mainly with fertilizers, is the formation of straw from the previous crop and the use of genus Azospirillum bacteria. The objective of this study was to evaluate the agronomic characteristics and yield of soybean, cultivated in areas under straw of

2. Composite Superabsorbent Hydrogel of Acrylic Copolymer and Eggshell: Effect of Biofiller Addition
Eggshell (ES) is an abundant waste material which is mainly composed of calcium carbonate. A superabsorbent hydrogel composite based on poly(acrylamide-co-potassium acrylate) as matrix containing 17 wt.% of chicken ES powder as a filler was synthesized and compared with the gel without filler. The characterization was carried out by Fourier transform infrare

3. Solid-Liquid Extraction with Low Temperature Purification Coupled with Gas Chromatography and Mass Spectrometry for Determination of Polychlorinated Biphenyls in Sewage Sludge
Sewage sludge is the residue produced by the wastewater treatment plants, which can be used as soil conditioner in agriculture. However, the current legislation recommends monitoring chemical contaminants such as polychlorinated biphenyls (PCBs). In this study, solid-liquid extraction with low temperature purification (SLE-LTP) was optimized and validated fo

4. Evaluation of pesticide residues in oranges from São Paulo, Brazil
Pesticides in “PERA” orange samples (N = 57) from São Paulo City, Brazil were assessed and the pesticide intake contribution was estimated for chronic risk assessment. Seventy-six pesticides were evaluated by the gas chromatography multi-residue method, including isomers and metabolites (4.332 determinations). The mean recoveries at the limit of quantif

5. Avaliação química e ecotoxicológica de lodos e esgoto visando à utilização na agricultura / Chemical and ecotoxicological assessment of sewage sludge aiming its use in agriculture
A destinação final de lodo de esgoto gerado nas estações de tratamento para a agricultura destaca-se por ser uma alternativa promissora e sustentável. Contudo, para se evitar efeitos adversos ao ecossistema e a saúde humana, este resíduo deve passar por uma rígida caracterização e monitoramento antes da sua aplicação. A Resolução CONAMA 375/200

6. DESENVOLVIMENTO E VALIDAÇÃO DE MÉTODO PARA DETERMINAÇÃO DE RESÍDUOS DE PESTICIDAS EM PLANTA MEDICINAL DESIDRATADA HYPTIS PECTINATA UTILIZANDO DMFS E CG/EM. / DEVELOPMENT AND VALIDATION OF METHODS FOR DETERMINATION OF PESTICIDE RESIDUES IN DRIED MEDICINAL PLANT HYPTIS PECTINATA DMFS AND USING GC / MS.
The Hyptis pectinata (L.) Poit is a medicinal plant widely used in the Sergipe state for the treatment of skin illnesses, gastric clutter, nasal congestion and inflammation caused for bacteria and fungi. Hyptis pectinata, as well as other medicinal plants, can be contaminated with pesticides that are used in the agriculture, and residues cause damages to the

7. LixiviaÃÃo, formaÃÃo de resÃduos ligados e biorremediaÃÃo de atrazina em solo subtropical submetido à aplicaÃÃo de Ãgua residuÃria da suinocultura / Leaching, bound residues formation and bioremediation of the atrazine in subtropical soil submitted of swine wastewater application
Atrazine is a triazine herbicide, widely used in agriculture to control weeds in corn and cane sugar farming. However, atrazine is considered a pesticide moderately persistent in the environment and the application of wastewater to the soil can affect its environmental performance. In this study, the effects of wastewater from swine (ARS) in leaching, dissip

8. Resíduos de agrotóxicos em alimentos: uma preocupação ambiental global - Um enfoque às maçãs
This paper describes the use of pesticides in agriculture. Research has shown that significant quantities of pesticide residues have been found in many types of foods. Thus, an overview is given of pesticide residue determinations in fruits and vegetables, with special attention to apples. The toxicity and the adverse effects possibly caused by the exposure

9. Uso de resíduo orgânico da produção de biodiesel direta da semente na atenuação dos efeitos de hidrocarbonetos de petróleo no solo. / Use of organic residue from the biodiesel production directly from the seed in the reduction of petroleum hydrocarbons effect in soil.
In the search for energy resources that can minimize the environmental impact in the transportation, refining and distribution of fossil fuels, biodiesel is highlighted as an economically viable alternative and totally renewable if compared to petroleum. With the regulations of Law 11097, from 2005, Brazil became widely known as one of the planet largest pro

10. Resposta de forrageiras à diferentes doses de lodo de curtume de tecnologia limpa em condições controladas e a campo / Response of forage to different doses of sludge from tannery of "clean technology" under controlled conditions and field
Industrial processes generate waste such as sludge from tannery "clean technology" that can be used in agriculture, to increase the productivity and supply of nutrients to the soilplant system. On this basis it was aimed to assess the feasibility of using primary sludge from a tannery in clean technology in the fertilization of pasture grasses and forage leg

11. DinÃmica de nutrientes em solos arenosos adubados com esterco bovino por longos perÃodos / Dynamics of nutrients in sandy soils amended with cattle manure for long periods
Additions of farmyard manure (FYM) to the soil are a widely adopted alternative to supply nutrients, particularly nitrogen and phosphorus, in areas of subsistence agriculture in the semi-arid and agreste of Paraiba State. Additions of this residue in quantities that far exceed crop uptake, for long periods, can cause accumulation of nutrients in the soil. Th

12. Evaluation of the use of a thermal isolation residue in the based calcium silicate in agriculture / Avaliação do uso de um resíduo de isolamento térmico a base de silicato de cálcio na agricultura
O presente estudo teve como objetivo geral avaliar a viabilidade agronômica, técnica e ambiental da destinação de um resíduo sólido a base de silicato de cálcio, proveniente de placas de isolamento térmico em tubulações superaquecidas da REDUC (Refinaria Duque de Caxias), como um insumo agrícola. Para tanto, foram conduzidos três ensaios, dividin
