Pobreza, privação e transferência de renda na várzea amazônica: um estudo de caso para Sirituba em Abaetetuba, Pará

A pobreza é um problema multidimensional que se traduz em termos de privações e insuficiência de capacidades básicas. Os índices multidimensionais permitem uma análise apurada da qualidade de vida relacionada com a pobreza, considerando algumas dimensões importantes e representam um grande avanço na problemática do planejamento do desenvolvimento. O objetivo geral dessa pesquisa foi o de analisar as privações enfrentadas pelas famílias na comunidade Sirituba em Abaetetuba/PA, de acordo com as dimensões e indicadores do Índice de Pobreza Multidimensional (IPM) e analisar o impacto de transferências de renda em bens duráveis domésticos das famílias. A análise com famílias que recebem e não recebem transferências de renda mostrou que a duas tem a mesma quantidade de bens duráveis domésticos. A análise adaptada do IPM para Sirituba constatou que algumas famílias sofrem privações devido à baixa escolaridade dos chefes de família, à falta de acesso seguro água potável, à falta de saneamento básico e ao método rústico para cozinhas. Verificou-se também uma tendência de melhora no Índice de Desenvolvimento Humano Municipal (IDHM) de Abaetetuba. O município evoluiu da faixa de “muito baixo desenvolvimento humano” para o “médio desenvolvimento humano”, isso representa uma evolução nos indicadores de educação, longevidade e renda. No entanto, sabe-se que a área urbana de Abaetetuba não apresenta os mesmos serviços públicos de uma área rural como Sirituba. O Censo 2000 e 2010 consideram dados diferentes para cada uma dessas áreas demonstrando que os serviços de energia elétrica e abastecimento de água, prestados na área rural, são menos disponíveis em comparação a área urbana de Abaetetuba.

Biodegradacao da hepatotoxina(D-Leu1)-microcistina-LR por bactérias presentes em filtros biológicos de carvão

The persistence of MCs in aquatic environments and their difficult removal in the conventional water treatment is a challenge to companies of sanitation. However, the MCs are susceptible to degradation by bacteria present in water, sediment and sewage effluents. In this study, we investigated the biodegradation of MCs by microorganism present in carbon filters with biological activity (BAC) and their phylogenetic identification by sequencing gene 16S RNA. A study of water containing MCs was used, with different compositions, plus a filters BAC effluent. The results showed that of MCs were biodegraded by microorganism present in the biofilm. This study provides the ability to complete biodegradation of MCs by bacteria present in BAC filters and the possible use of these microorganisms as alternative of the removal of MCs in the treatment of drinking water

Control of Salmonella Enteritidis in turkeys using organic acids and competitive exclusion product

Aim: To evaluate the use of organic acids (OAs) and competitive exclusion (CE) product administered continuously in the feed and transiently in drinking water on the control of Salmonella enterica subspecie enterica serotype Enteritidis (SE) prior to slaughter.Methods and Results: The influence of treatments were evaluated on pH, population of the lactic acid bacteria (LAB) and bacteria of the family Enterobacteriaceae, concentration of volatile fatty acids and SE colonization in the crop and caecum. The birds were challenged with SE 24 h before being slaughtered, and then, the caeca and crop were removed and subjected to SE counts. Continuous administration of OAs reduced the population of bacteria from the Enterobacteriaceae family in both crop and caecum, positively influenced the butyric acid concentration and reduced SE colonization in the caecum. The diet supplemented with CE product positively influenced the quantity of LAB in the crop and caecum, elevated the butyric acid concentration and reduced both Enterobacteriaceae quantity and SE colonization in the caecum. There was no effect from administering the treatments via drinking water on the variables measured.Conclusions: Continuous supplementation in feed with OAs and CE product reduced SE colonization of the caeca.Significance and Impact of the Study: Supplementation of OAs and CE product in diet to turkeys can reduce the SE load, potentially leading to a lower contamination risk of meat during slaughter.

Validação e aplicação de método para análise de pesticidas em água para consumo humano de dourados (ms) por CLAE/UV e CG/DTE

Indiscriminate and inappropriate use of pesticides in agriculture has been pointed out for increasing health problems and environmental damage. Considering that water resources are the principal destiny of those compounds after application, the present study presents optimization and validation of two simple and effi cient analytical methods for pesticides quantifi cation in both surface and groundwater. Were selected the pesticides more commonly used at Dourados (MS - Brazil), region with intense agricultural activity. Pesticides were preconcentrated by solid-phase extraction using C18 (500 mg) cartridges and then divided in two groups for elution and quantifi cation: 2.4-D and 2.4-DCP were eluted with methanol and quantifi ed by high performance liquid chromatography with ultra-violet detector (HPLC-UV) while atrazine, DIA, DEA, trifl uralin and methyl parathion were eluted with ethylacetate (1:1, v/v) and quantifi ed by gas chromatography with thermionic specifi c detector (GC-TSD). The methods showed satisfactory accuracy (76-107%) and precision (<12%) for the substances analyzed at the fortifi ed levels selected for the study, except for DIA (<51%). Study of pesticide stability also presented good results: C18 cartridges could be stored for at least for 21 days at -20ºC with no signs of the compounds degradability. Both methods limits of quantifi cation of the pesticides (0.22 - 0.48 μg L-1) are in accordance to the levels currently established by the Brazilian national legislation for pesticides in water. Although only the pesticide 2.4-D has been detected in two distinct collection points in the study period of time, this work warns for the requirement of systematical analysis of pesticides presence in water destined to human consume, principally in areas of intense agriculture activity. Such monitoring can provide subsidies for public environmental policies.

Tecnologias de captação e aproveitamento de água de chuva para residências uni familiares

Water scarcity is becoming an increasing problem and more evident worldwide, rainwater utilization is characterized for being one of the simplest and cheapest solutions to preserve drinking water and is a known alternative technology and used to promote sustainability in buildings and reducing pressure on surface waters, it would also reduce runoff and can minimize flooding. The rainwater, while not potable may be used in potable water usage activities, and may thus saving 30 to 40% of potable water. In this work one can see the importance of the capture and use of rainwater (CAAC), bringing economy, to reduce consumption of potable water, reducing the problem of water shortage, and which methods and materials needed to cause its implementation. The work also promoted the characterization of rainwater in the city of Guaratinguetá (SP) and studied its potential use in public housing, calculating the volume needed for implementation of the tank and the cost to implement all rainwater utilization system, but because it is a region with a median rainfall index and the popular houses present an area of small water capitation, the result was not satisfactory. The cost for implementation was high and the financial return was well above average. The government should encourage and support more CAAC, as not thinking about the financial side is advisable to be widespread throughout the country, the benefits it can bring
