1. Biomonitors to evaluate the toxic potential of urban solid waste landfill leachate
Resumo O aumento acentuado da produção de resíduos sólidos urbanos (RSU) e o consequente acúmulo de lixiviado em aterros potencializam o risco de contaminação do meio ambiente. Biomonitores são utilizados para avaliação da toxicidade dos poluentes sobre os organismos vivos. Neste estudo, foram avaliados o potencial poluidor do lixiviado de RSU de u

2. SWINE WASTEWATER: IMPACTS ON SOIL, PLANT, AND LEACHATE
ABSTRACT: The use of animal-origin residues as a nutrient source without prior and proper investigations on their positive and negative impacts can affect the quality of agricultural soils and the environment into which they are inserted. In this sense, the aim of this study was to assess the impact of swine wastewater and mineral fertilization application o

3. CORN FERTILIZATION USING SWINE WASTEWATER AND SOIL-WATER ENVIRONMENTAL QUALITY
ABSTRACT: Soil application of swine wastewater for nutrient cycling may represent a correct destination of these residues and reduction in production costs. However, when applied to soil, such residue may cause environmental impacts. This study aimed to analyze the chemical characteristics of the soil, corn, and leachate after successive swine wastewater app

4. Dinâmica do cromo em solos fertilizados com proteína hidrolisada de couro / Dynamics of chromium in soil fertilized with leather hydrolysate
This study intends to subsidize the decision for utilizing leather hidrolysate as fertilizer in the state of Rio Grande do Sul. The distribution and potential mobility of chromium in different soils, applied in increasing amounts of leather hidrolysate were investigated. The analyses involved sequential fractioning procedure and speciation of chromium, in ad

5. Estudo dos lixiviados das frações do aterro sanitário de São Carlos - SP por meio da caracterização físico-química / Study from de leachate of fractions from São Carlos landfill - SP through the physicochemical characterization
This work aimed to determine the stages of the decomposition of the waste disposed in São Carlos - SP landfill fractions through the study of the characteristics of the generated leachate. Samples were collected from the older area of the landfill (closed 10 years ago), and also from the first, second and third new built areas (garbage is still being dumped

6. Lixiviado de aterros sanitários brasileiros: estudo de remoção do nitrogênio amoniacal por processo de arraste com ar ("stripping") / Sanitary landfill leachate in Brazil: evaluation of ammonia nitrogen removal by air stripping process
Sanitary landfills are considered as the most appropriate way for final disposal of municipal solid wastes in Brazil, in the technical and economical point of view. Open dumps have been progressively substituted by well engineered and operated landfills. However, landfills still present environmental risks due to the gas emission and leachate production. Gas

7. Remoção de nitrogênio de lixiviado de resíduos sólidos urbanos por meio do processo nitrificação/desnitrificação via nitrito em reator em bateladas sequenciais / Nitrogen removal from solid waste leachate by nitrification/denitrification via nitrite in a sequencing batch reactor.
The leachate is an effluent with high potential to cause environmental problems in receiving body due to the high concentrations of ammoniacal nitrogen. Currently, several treatment processes have been studied to promote nitrogen removal by the hand of conventional process variations. Therefore, the present study was developed to evaluate the performance of

8. Avaliação da co-disposição do lodo de tanques sépticos e fração orgânica de resíduos sólidos domiciliares em reatores anaeróbios / Evaluation of co-disposal of sludge from septic tanks and organic fraction of domestic solid waste in anaerobic reactors
Despite being an emerging country, unfortunately the sanitary situation of Brazil is quite precarious. Only 52.2% of the 5,507 brazilian municipalities have some type of sanitary service (IBGE, 2000). In this alarming scenario, individual solutions are gaining more importance. The adoption of septic tanks as an alternative to the solution of the sewage becom

9. Estudo hidrogeológico de um aterro sanitário instalado em uma antiga área de disposição irregular de resíduos sólidos / Hydrogeological research of a landfill set up in a previously irregular solid waste disposal area
In the past, the disposal of solid residue without any type of treatment and control was a common and widespread practice. As a result of that, the old areas used as dump have become a serious environmental and public health problem. Some of these areas are being reused in constructions now known as landfills, this time in a way that they arent a threat anym

10. Characteristics Physiochemical and Microbiology of the Leachate of the Controlled Landfill of Solids Wastes of Aguazinha/Olinda-PE / Monitoramento fÃsico-quÃmico e microbiolÃgico do lixiviado do aterro controlado de resÃduos sÃlidos urbanos de Aguazinha em Olinda PE
This research it approaches the study of the physiochemical characteristics and microbiology of those leachate produced starting from two cells of disposition of solid wastes of the Controlled Landfill of Aguazinha, located in the municipal of Olinda-PE. The study presents an approach about the characteristics of those leachate and contribution as subsidy to

11. Estudo da evaporaÃÃo de lixiviados de aterros sanitÃrios como alternativa tecnolÃgica de tratamento: testes em bancada
The leachate from landfill contains high pollution load and its composition gives large amounts of ammonia, chlorides, recalcitrant substances, organic and inorganic compounds. Such waste can cause negative effects on the environment and interfere with the performance of biological processes for their degradation. The choice of technology appropriate treatme

12. Avaliação das características microbiológicas e físico-químicas do lixiviado (chorume) no processo de tratamento do Aterro Metropolitano de Gramacho (Rj Brasil) / Evaluation of microbiological and physic-chemical characteristics of leachate in Gramacho landfill treatment process (RJ-Brazil)
Garbage has dramatically increased in XX century, resulting in the expansion of the demand for areas to place it. In Brazil, one of the alternatives for the garbage destination have been the landfills. This option has consequences, as leachate generation. It is a dark liquid that presents highly soluble substances as result of biological degradation process
