Genotoxicidade e composição do material particulado emitido pela queima de Biomassa: um estudo de caso em Tangará da Serra, Região da Amazônia Brasileira

Tangara da Serra is located on southwestern Mato Grosso and is found to be on the route of pollutants dispersion originated in the Legal Amazon s deforestation area. This region has also a wide area of sugarcane culture, setting this site quite exposed to atmospheric pollutants. The objective of this work was to evaluate the genotoxicity of three different concentrations of organic particulate matter which was collected from August through December / 2008 in Tangara da Serra, using micronucleus test in Tradescantia pallida (Trad-MCN). The levels of particulate matter less than 10μm (MP10) and black carbon (BC) collected on the Teflon and polycarbonate filters were determined as well. Also, the alkanes and polycyclic aromatic hydrocarbons (PAHs) were identified and quantified on the samples from the burning period by gas chromatography detector with flame ionization detection (GC-FID). The results from the analyzing of alkanes indicate an antropic influence. Among the PAHs, the retene was the one found on the higher quantity and it is an indicator of biomass burning. The compounds indene(1,2,3-cd)pyrene and benzo(k)fluoranthene were identified on the samples and are considered to be potentially mutagenic and carcinogenic. By using Trad-MCN, it was observed a significant increase on the micronucleus frequency during the burning period, and this fact can be related to the mutagenic PAHs which were found on such extracts. When the period of less burnings is analyzed and compared to the negative control group, it was noted that there was no significant difference on the micronuclei rate. On the other hand, when the higher burning period is analyzed, statistically significant differences were evident. This study showed that the Trad-MCN was sensible and efficient on evaluating the genotoxicity potencial of organic matter from biomass burning, and also, emphasizes the importance of performing a chemical composition analysis in order to achieve a complete diagnosis on environmental risk control

Efeito da intensidade luminosa no desenvolvimento larval do camarão-da-amazônia, Macrobrachium amazonicum

The effects of four light intensities (0; 2.8 +/- 0.9; 5,5 +/- 1,8 e 7,8 +/- 2,5 mu mol s(-1) m(-2), about 136.5 +/- 87.5; 273 +/- 43.8 e 390 +/- 125 lux, respectively) on survival, productivity, weight gain and larval development of Macrobrachium amazonicum were investigated. Four treatments with three replicate tanks were evaluated. Newly hatched larvae were held in black tanks (80.2 +/- 0.6 larvae L(-1)) filled with 50-L-brackish water (salinity of 10), in a recirculating system. Tanks were covered with shadow cloth allowing 35% and 70% light, respectively, to reach light intensities of 2.8 +/- 0.9 and 5.5 +/- 1.8 mu mol s(-1) m(-2) at the water surface. Complete absence of light (0 mu mol s(-1) m(-2)) was obtained covering the tanks with opaque black plastic, and full-light condition used no covering (7.8 +/- 2.5 mu mol s(-1) m(-2)). Observations showed that the survival rate was not affected by light intensity. Productivity and weight gain were higher under 7.8 +/- 2.5 mu mol s(-1) m(-2) light intensity than under 0 and 2.8 +/- 0.9 1 mu mol s(-1) m(-2) intensities (P<0.05). The larval development index was similar among the treatments under the different light intensities. However, from stage VII this index was increased slightly in the treatment under 7.8 +/- 2.5 mu mol s(-1) m(-2) light intensity. In conclusion, light intensity affects larval development of M. amazonicum. Values as high as 7.8 mu mol s(-1) m(-2) (about 390 lux) improve the larval performance by enhancing development, productivity and weight gain compared to lower values.

Uso de bandejas de alimentação na fase de engorda do camarão-da-Amazônia Macrobrachium amazonicum (HELLER, 1862)

The aim of this experiment was to evaluate the hypothesis that the M. amazonicum prawns accept feeding in trays. Six ponds were stocked with 10 juveniles II (1.2 +/- 0.7 g) per m(2) in 02/14/2003. An entirely randomized experimental design with 2 treatments (feeding in trays or feeding to the throw) and 3 replicates was used. Prawn average weight, survival, productivity, and physical and chemical variables of the water were compared between treatments using "t" test of Student. Average weight, survival and productivity were, respectively, 7.2 +/- 0.3 g, 46.8 +/- 7.8% and 335 +/- 45 kg/ha in feeding tray treatment and 6.8 +/- 0.1 g, 85.8 +/- 5.2% and 586 +/- 42 kg/ha in feed to the throw treatment. Survival and productivity differed significantly (p<0.5), while that average weight didn't differ significantly. M. amazonicum needs to use further number of trays per area, possibly due to territorial and aggressive behavior.

Densidade de estocagem para produção de Acará-bandeira em viveiros escavados em policultivo com Camarão-da-amazônia

The aim of this study was to evaluate the production of Freshwater Angelfish (Pterophyllum scalare) in different stocking densities in cages polycultured with Amazon River Prawn (Macrobrachium amazonicum). Four treatments were evaluated (1; 2; 3 and 4 fish. 10 L(-1)) using two ponds and 24 experimental units. Water quality parameter reached adequate levels for the species. Production data were submitted to ANOVA. Fish produced in the lowest density showed higher values of final weight and standard length, and lower total biomass in comparison with the others treatments. Feed conversion rate, survival, batch uniformity and body factor were not significant different among treatments. The highest density tested produced more fish and gross yield than the others treatments. The density 20 fish. 10L(-1) is recommended to produce Freshwater Angelfish in cages polycultured with Amazon River Prawn.

Desenvolvimento, sustentabilidade e conservação da biodiversidade na amazônia: a produção familiar agroextrativista em áreas protegidas no sul do amapá

The establishment of Extractivism and Sustainable Development Reserves comes from an amazon forestry people resistance initiative. It means an option of natural resources management as protected areas for agroextractivism purposes. According to the institutional point of view, these lands, called Conservation Unity for Sustainable Exploration, belong to the government which grants the usufruct rights to the agroextractivist families under a sharing territory administration agreement among government and rural communities. The main roles of these lands are both: to improve the dwellers wellbeing, and protecting the local biodiversity. Additionally, they also represent the start of this thesis theme entitled Development, sustainability, and biodiversity conservation in the Amazon region: the use of protected areas for agroextractivism domestic yield in south of Amapá state with the objective of analyzing the performance that each territory has been reaching in terms of the attributions proposed at the beginning, when they were created. Social, economics, and environment changes that occurred in the agroextractivist areas have been evaluated from two selected test sites, named Rio Cajari Extractivist Reserve and Rio Iratapuru Sustainable Reserve, both, localized in the south of Amapá state

Trabalho, educação e desenvolvimento: o norte da educação da CUT na Amazônia

This thesis is the result of a bibliographic and field research, with the purpose to answer in what way the process of education developed by the CUT, expressed in the experience of the Project Vento Norte, developed in the Amazônia has colaborated in the sense of the possibility of a articulation between work, education, and develpoment. The bibliographic reasearch was based in the studies of theoreticals like Gadotti (1999), Marx (1998, 1998a), Pochman (2002), Brandão (1985, 2002), Adorno (1999, 2000), Horkeimer (1976), reseachers that in the process of their studies, thinked about the theme, related to work, to education and to developement. The field research was done by the intervews with CUT s educators and managers from the states of Acre, Amazonas, Amapá, Pará, Rondônia and Roraima. The thesis s process of elaboration is done in a cobweb of elements articulated to socioculture values from the habitat of amazônia people. The conclusions point to us that the hypothesis of the CUT, by the Project Vento Norte, develops a propose of education that articulates Work, Education and Development that is confirmed. But, the partiality of the project is presented by the limitations of the CUT s possibility in continuation of the project. Thats why the thesis suports the idea of the project and it consolidation in the Amazônica Region, by the conception of the syndicate managers and educators

Desenvolvimento e projeto de colhedora de babaçu (Orbignya phalerata Mart.) para agricultura familiar nas regiões de matas de transição da Amazônia

O babaçu (Orbignya phalerata) é uma típica palmeira das matas de transição dos ecossistemas Amazônia/Cerrado e Amazônia/Caatinga, sendo de grande importância econômica, social e ambiental nestas regiões. Os produtos advindos dos babaçuais possibilitam renda para uma das camadas mais pobres da região amazônica e um dos entraves para a obtenção eficiente destes produtos é a colheita dos cocos de babaçu, que atualmente se faz no sistema extrativista. O objetivo deste trabalho foi realizar o desenvolvimento e projeto de uma colhedora de babaçu adaptável ao ambiente de trabalho da agricultura familiar e as características das matas de transição amazônicas. Para tal foram realizados estudos de literatura que nortearam as decisões e simplificações de projeto, assim como foram realizados os cálculos e desenhos da nova colhedora. O projeto foi realizado através de ferramentas de engenharia que apresentaram como resultados o memorial de cálculo que descreve o caminho técnico para o dimensionamento dos elementos constituintes da colhedora e a partir destes os desenhos detalhados dos elementos da nova máquina. Pelos desenhos detalhados suas considerações e decisões concluí-se que a colhedora de babaçu apresenta-se passível de ser construída com materiais nacionais de baixo custo, além de fácil operação, manutenção e com mínimo efeito sobre os babaçuais naturais.

Da Amazônia ao Pacífico cruzando os Andes

A Área Amazônica (AA) é compartilhada por oito países sul-americanos independentes. Desde os tempos coloniais sentiu-se a necessidade da construção de uma via de união da AA com o Oceano Pacífico. Mas os Andes, em termos técnicos e econômicos, foram barreira insuperável até as últimas décadas do século XIX. Nos últimos anos, para o Brasil - país que tem perto de 60% da AA -, esta via vem se tornando cada vez mais importante em termos de exportação, especialmente para o mercado japonês, de grãos, madeira, polpa de madeira etc., ao mesmo tempo em que o Japão também deseja acesso direto à AA. Brasil e Peru, segundo país da AA, com a maior e mais ocidental costa no Pacífico, têm desenvolvido projetos para a construção de uma estrada, contando para isso com apoio financeiro oferecido pelo Japão em diversas oportunidades. Tais projetos tentam conciliar não apenas os interesses de Brasil e Peru, mas também os da Bolívia, país mediterrâneo que poderia finalmente ter acesso livre à costa do Pacífico. Os Estados Unidos, porém, opõem-se a construção da mencionada via e, o projeto está a espera de que o financiamento anteriormente aventado permita sua concretização. Parece que, na construção da projetada estrada, interesses estratégicos das grandes potências mundiais estão envolvidos.

Memórias de rios e de lagos na construção romanesca: leitura de narrativas da Amazônia paraense

This study focalizes the memoirs of rivers and of lakes in the romantic construction starting from the romances Chove nos campos de Cachoeira (1941), Marajó (1947) and Três casas e um rio (1958), of writer Dalcídio Jurandir; of the book of memoirs Marajó, minha vida (1998), of writer Dita Acatauassu; of the story "A Feiticeira", published in the book Contos Amazônicos, written by Inglês de Sousa (1883); of the short story "O Peixe", published in O carro dos milagres, (1990), of writer Benedicto Monteiro; of the oral narratives Honorato: Cobra Grande , O encanto de Honorato and A Lenda da Cobra Norato , picked up by the project named The Imaginary in the Shape of Oral Narratives of Paraense Amazon (IFNOPAP) of the Federal University of Pará. In those speeches, the voices of the memory detach the multiple functions of rivers and lakes represented as space, atmosphere, scenery, route and route, thread and fabric, re-elaborated in the narrators' memoirs, characters and narrators/character of the fiction and in popular narratives

Aproveitamento de alimentos de origem animal pela tartaruga-da-amazônia: Podocnemis expansa criada em cativeiro

Foi realizado um trabalho para determinar o aproveitamento alimentar da farinha de carne e ossos (FCO), farinha de vísceras de aves (FVA) e farinha de peixe (FP) em tartaruga-da-amazônia, por meio dos coeficientes de digestibilidade aparente (CDA) da matéria seca (MS), proteína bruta (PB), extrato etéreo (EE) e energia bruta (EB). Os animais experimentais foram 136 filhotes provenientes do Projeto Quelônios da Amazônia, no estado do Mato Grosso, mantidos em caixas com renovação de água e temperatura média de 29ºC. Os CDA foram determinados com dietas contendo 0,1% do marcador óxido de crômio III (Cr2O3). Os CDA da MS, PB, EE e EB foram, respectivamente, de 79,10; 87,61; 93,83 e 79,61% para FCO; 92,45; 94,89; 96,55 e 92,71% para FV e 93,53; 95,13; 94,05 e 93,18% para FP. Os melhores coeficientes foram obtidos com a farinha de peixe e a farinha de vísceras de aves.

Avaliação de Hb A2 e Hb F em doadores de sangue de região malarígena da Amazônia Oriental brasileira por HPLC

In malaria endemic regions of Africa, resistance to infection by Plasmodium has been observed in under 6-month-old children, when there are higher fetal hemoglobin (Hb F) levels. Research performed in the São José do Rio Preto region, central-east Brazil, reported increased levels of Hb F in blood donors. The purpose of this work was to evaluate the A2 hemoglobin (Hb A2) and Hb F concentrations in blood donors deriving from the Brazilian malaria endemic region. Forty-five blood donor samples from Macapá, from patients with varying genders, ages and ethnic origins, were collected by venous puncture after informed consent was obtained. The samples were analyzed by High Performance Liquid Chromatography (HPLC) - System Variant (Bio-Rad). The HPLC demonstrated sensitivity and rapidity in the identification and measurement of the hemoglobins and gave precise results. Moreover, it provided measurement of hemoglobin variants, even when they were present in small amounts, providing a diagnosis of hemoglobinopathies. Hb F levels above the normal were observed in 33.3% of the analyzed samples. The presence of increased Hb F can suggest resistance to infection by Plasmodium falciparum, as there have been reports that infected red blood cells interfere in the development of the parasite.
