Atributos físico-hídricos de um Latossolo após a aplicação de lodo de esgoto em área degradada do Cerrado

Os solos cultivados intensivamente e inadequadamente são degradados, assim como a construção de obras civis no meio rural executada sem atender à legislação. O trabalho objetivou definir a interferência do lodo de esgoto na recuperação de atributos de um Latossolo Vermelho. O experimento foi implantado em 2004, em Selviria (MS). Os tratamentos utilizados foram: T1-vegetação de cerrado; T2-solo exposto sem tratamento para recuperação; T3-solo cultivado com eucalipto e braquiária sem o uso do lodo de esgoto e adubação mineral; T4-solo cultivado com eucalipto e braquiária com adubação mineral; T5-solo cultivado com eucalipto e braquiária com uso de 30Mg ha-1 de lodo de esgoto e; T6-solo cultivado com eucalipto e braquiária com uso de 60Mg ha-1 de lodo de esgoto. Nas camadas do solo de 0,00-0,05; 0,05-0,10; 0,10-0,20 e de 0,20-0,30m, foram avaliados os atributos físico-hídricos e teor de matéria orgânica. Os tratamentos com adubação mineral e orgânica estão agindo de forma semelhante para a recuperação dos atributos físico-hídricos e do teor de matéria orgânica. em solos degradados pela construção de obras civis a aplicação de 30 a 60mg de lodo de esgoto ha-1 recupera as suas propriedades físico-hídricas.

Influência do tamanho e da forma da semente de milho sobre o desenvolvimento da planta e a produtividade de grãos

Due to the small and the round seeds represent a rather high proportion of an ear, this experiment viewed to study the effects of those factors on seed germinative performance in the field as well as on the plant traits related to grain yield. Six treatment combinations replicated five times were sown in Votuporanga/SP on 08/22/2008. Flat shaped (C) and round shaped (R) seeds were made to go through flat round and oblong hole screens which resulted in the following treatments: 1. C1: seeds remaining on the top of a 23/64 '' round hole screen, 2. C2G: 21/64 '', 3. C3M: 17/64 '' or 16/64 '', 4. R2GM: medium length seeds remaining on the top of 13 x 3/4 '' oblong hole screen, 5. R3M: medium length seeds remaining on a 12 x 3/4 '' (from 1 to 2 mm bigger than R3), and 6. R3: 12 x 3/4 ''. The soil of the experimental area was submitted to a no-till cultivation system and the rows were set 0.6 m apart from one another. Fifteen days after emergence (DAE), the plants were thinned to a population of 66,000 plants/ha. Harvest took place 115 DAE and the mean yield was of 12,498 kg ha(-1). Based on the results it was concluded that only the initial growth of the plants is significantly affected by seed size. Plant traits such as plant height, ear insertion height, culm diameter, number of grains per year, grain weight and size as well as grain yield evaluated 40 or more DAE are not significantly affected by seed size or seed shape.

Tempo de latência e duração do efeito do rocurônio, atracúrio e mivacúrio em pacientes pediátricos

JUSTIFICATIVA E OBJETIVOS: Os bloqueadores neuromusculares (BNM) são freqüentemente utilizados em anestesia pediátrica e não existe aquele considerado ideal. O objetivo deste trabalho foi avaliar o rocurônio, o atracúrio e o mivacúrio, em crianças, quanto ao tempo de latência e de recuperação, à interferência sobre as variáveis hemodinâmicas e às condições de intubação traqueal. MÉTODO: Sessenta e sete crianças, estado físico ASA I e II, com idade variando de 2 anos e 6 meses a 12 anos, foram anestesiadas com alfentanil (50 µg.kg-1), propofol (3 mg.kg-1), sevoflurano e N2O/O2 e divididas em três grupos: G1 = rocurônio 0,9 mg.kg-1 (n = 22); G2 = atracúrio 0,5 mg.kg-1 (n = 22) e G3 = mivacúrio 0,15 mg.kg-1 (n = 23). A monitorização do bloqueio neuromuscular foi realizada com o método de aceleromiografia no trajeto do nervo ulnar. Foram estudados: o tempo de latência (TL), a duração clínica (T25), o tempo de relaxamento (T75) e o índice de recuperação (T25-75). A pressão arterial média (PAM) e a freqüência cardíaca (FC) foram registradas em seis momentos, bem como as condições encontradas no momento da intubação traqueal. RESULTADOS: A mediana do TL foi de 0,6 minutos em G1, 1,3 minutos em G2 e 1,9 minutos em G3. A mediana do T25 foi em G1 = 38 minutos, G2 = 41,5 minutos e G3 = 8,8 minutos. A mediana do T75 foi em G1 = 57,7 minutos, G2 = 54,6 minutos e G3 = 13,6 minutos. A mediana do índice de recuperação (T25-75) foi em G1 = 19,7 minutos, G2 = 13,1 minutos e G3 = 4,8 minutos. As condições de intubação traqueal foram consideradas excelentes na maioria dos pacientes de ambos os grupos. Não houve modificações clínicas importantes da PAM e da FC. CONCLUSÕES: O rocurônio, 0,9 mg.kg-1, teve o menor tempo de latência e o mivacúrio, 0,15 mg.kg-1, o menor tempo de recuperação nos pacientes pediátricos anestesiados com sevoflurano. Também, o rocurônio, o mivacúrio e o atracúrio não determinaram alterações hemodinâmicas de importância clínica relevante e proporcionaram excelentes condições de intubação traqueal.

Turismo, capital social e produção do espaço: uma leitura a partir do município de Natal/RN no período de 1980 a 2012

Nowadays, there is a tourism phase in the city of Natal/RN called internationalization of tourism , which shows a tourism model with a planning and an administration, based on the needs of the visitors. Such process shows that the production as well as the reproduction of the city spaces with the goal of favor tourism excludes of its composition the effective participation of local subjects. Thus, the research is a result of the perception of tourism as an activity with a meaningful power of transformation of the social and natural space taking into account the low participation of the residents in the decisions of the tourism activities in the city of Natal/RN. Despite that reality, it is possible to note Natal that civil society, starts to mobilize its citizens trying to develop collective actions to low the negative impacts caused by the bad planning as wells not efficient tourism administration, trying to put in action the right of the local population to take part in the decisions of the city activities. Having this panorama as background, this paper aims at investigating in which way the mobilizing action of the social capital in Natal has contributed to change the spatial production which is part of the process of expansion of tourism in Natal/RN? The research presents a temporal picture which starts in the year of 1980, when occurs the first effective state intervention aiming to develop tourism in the capital, taking into account an analysis of 2012. Concerning the spatial picture, the research investigates the beaches of Natal which concentrates criteria and actions such as: visitation, tourism appeal and focus of investments, highlighting the following beaches: Ponta Negra, Areia Preta, Praia dos Artistas, Praia do Meio, Praia do Forte and Redinha. This study is of a descriptive and exploratory nature concerning its goals. With respect to the treatment of its object it is a qualitative research. The data was collected through structural interviews, with open questions. Regarding the methodological choices, it was used the content analysis proposed as well as the collective discursive subject methodology. The results show that there´s not yet in Natal a meaningful social capital related to tourism, capable to change the spatial production related to the activity. It should be stressed that Natal social capital presents difficulties concerning the incentive to trust, spontaneous cooperation and the civic participation, which are the foundation for the development of an effective social capital, which makes it harder for a more expressive articulation in the reality in Natal/RN. It should be stressed, as an answer to the research questions, that tourism in Natal/RN is represented by social and spatial segregation. In other words it emphasizes mainly the action of hegemonic agents (State and market), leaving little room for the participation of society. It can be noticed that the actions related to tourism in Natal keeps the popular participation out of the way. Thus, it can be said that the social capital in Natal/RN does not yet contribute to a more fair spatial production related to the expansion of the tourism as well as the well being of the population of Natal/RN. In conclusion, it should be taken into account that this participation do exists but not in a meaningful way. In other words, it´s not enough yet to cause meaningful changes in the actions which tourism needs nowadays in Natal/RN

Efeitos da ligadura do ducto pancreático e da secção ductal com livre drenagem de secreções para o peritônio sobre as funções endócrina e exócrina do pâncreas: estudo clínico e laboratorial em coelhos

As ressecções pancreáticas seguidas de anastomoses acompanham-se de altas taxas de morbidade, que incluem: surtos de pancreatite e, principalmente, fístulas digestivas. Nos transplantes pancreáticos a drenagem da parte exócrina do enxerto para o intestino ou para a bexiga, além das peculiaridades técnicas, também não é isenta de diversas complicações. Visando evitar ou atenuar tais conseqüências e simplificar a técnica cirúrgica, têm sido usadas outras abordagens para o tratamento ductal do coto/enxerto pancreático, tais como: drenagem livre de secreções para o peritônio, com o ducto pancreático aberto, ligadura ductal e oclusão do ducto com polímeros sintéticos. OBJETIVO: O presente estudo visa avaliar clínica e laboratorialmente as funções endócrina e exócrina do pâncreas de coelhos com o ducto aberto e ligado. MÉTODOS: Foram realizadas 150 operações, divididas em 3 grupos: N - manipulação/controle (n=50), A - grupo aberto (n=50), e L - ligado (n=50). Os momentos de observação foram pré-operatório, dia 0 (dia da operação) e pós-operatório (observação e sacrifício): 7 dias, 14 dias, 28 dias, 90 dias e 180 dias. Os parâmetros analisados foram: estado geral, atividade, controles do peso corporal, ingestão hídrica, ingestão alimentar e dosagens da amilase sangüínea, glicemia, glicose urinária e insulina plasmática. RESULTADOS: Todos os grupos tiveram evolução clínica similar, com bom estado geral, ganho ponderal progressivo e valores normais da ingestão hídrica e ingestão alimentar. Exceto uma significativa elevação da amilase sangüínea nas primeiras 24-48h para os 2 grupos com interferência ductal, não houve qualquer alteração dos níveis basais da glicemia, glicosúria e insulinemia entre os 3 grupos experimentais, em todos os momentos de observação. CONCLUSÃO: À exceção da amilase sangüínea, cujos níveis basais foram significativamente elevados no 1º e 2º dias de pós-operatório, as duas modalidades técnicas de abordagem da secreção exócrina do pâncreas, utilizadas em coelhos, não determinaram quaisquer alterações clínicas, bem como dos níveis basais de glicose sangüínea, glicose urinária e insulina plasmática, durante 6 meses de seguimento.

Sistemas computacionais espaço-temporais para toma de decisão em questões ambientais relacionadas à indústria de petróleo e gás

The area between São Bento do Norte and Macau cities, located in the northern coast of the Rio Grande do Norte State is submitted to intense and constant processes of littoral and aeolian transport, causing erosion, alterations in the sediments balance and modifications in the shoreline. Beyond these natural factors, the human interference is huge in the surroundings, composed by sensitive places, due to the existence of the Guamaré Petroliferous Pole, RN, the greater terrestrial oil producing in Brazil, besides the activities of the salt companies and shrimp farms. This socioeconomic-environmental context justifies the elaboration of strategies of environmental monitoring of that coastal area. In the environmental monitoring of coastal strips, submitted to human impacts, the use of multi-sources and multitemporal data integrated through a Spatio- Temporal Database that allows the multiuser friendly access. The objective was to use the potential of the computational systems as important tools the managers of environmental monitoring. The stored data in the form of a virtual library aid in making decisions from the related results and presented in different formats. This procedure enlarges the use of the data in the preventive attendance, in the planning of future actions and in the definition of new lines of researches on the area, in a multiscale approach. Another activity of this Thesis consisted on the development of a computational system to automate the process to elaborate Oil-Spill Environmental Sensitivity Maps, based on the temporal variations that some coastal ecosystems present in the sensibility to the oil. The maps generated in this way, based on the methodology proposed by the Ministério do Meio Ambiente, supply more updated information about the behavior of the ecosystem, as a support to the operations in case of oil spill. Some parameters, such as the hydrodynamic data, the declivity of the beach face, types of resources in risk (environmental, economical, human or cultural) and use and occupation of the area are some of the essential basic information in the elaboration of the sensitivity maps, which suffer temporal alterations.In this way, the two computational systems developed are considered support systems to the decision, because they provide operational subsidies to the environmental monitoring of the coastal areas, considering the transformations in the behavior of coastal elements resulting from temporal changes related the human and/or natural interference of the environment

Avaliação de impacto ambiental e gestão dos recursos natuarias no estuário Apodi Mossoró, nordeste do Brasil

The aim of this study is to investigate the eco-environmental vulnerability, its changes, and its causes to develop a management system for application of eco-environmental vulnerability and risk assessment in the Apodi-Mossory estuary, Northeast Brazil. This analysis is focused on the interference of the landscape conditions, and its changes, due to the following factors: the oil and natural gas industry, tropical fruits industry, shrimp farms, marine salt industry, occupation of the sensitive areas; demand for land, vegetation degradation, siltation in rivers, severe flooding, sea level rise (SLR), coastal dynamics, low and flat topography, high ecological value and tourism in the region and the rapid growth of urbanization. Conventional and remote sensing data were analyzed using modeling techniques based on ArcGIS, ER-Mapper, ERDAS Imagine and ENVI software. Digital images were initially processed by Principal Component Analysis and transformation of the maximum fraction of noise, and then all bands were normalized to reduce errors caused by bands of different sizes. They were integrated in a Geographic Information System analysis to detect changes, to generate digital elevation models, geomorphic indices and other variables of the study area. A three band color combination of multispectral bands was used to monitor changes of land and vegetation cover from 1986 to 2009. This task also included the analysis of various secondary data, such as field data, socioeconomic data, environmental data and prospects growth. The main objective of this study was to improve our understanding of eco-environmental vulnerability and risk assessment; it´s causes basically show the intensity, its distribution and human-environment effect on the ecosystem, and identify the high and low sensitive areas and area of inundation due to future SLR, and the loss of land due to coastal erosion in the Apodi-Mossoró estuary in order to establish a strategy for sustainable land use. The developed model includes some basic factors such as geology, geomorphology, soils, land use / land cover, vegetation cover, slope, topography and hydrology. The numerical results indicate that 9.86% of total study area was under very high vulnerability, 29.12% high vulnerability, 52.90% moderate vulnerability and 2.23% were in the category of very low vulnerability. The analysis indicates that 216.1 km² and 362.8 km² area flooded on 1m and 10m in sea levels respectively. The sectors most affected were residential, industrial and recreational areas, agricultural land, and ecosystems of high environmental sensitivity. The results showed that changes in eco-environmental vulnerability have a significant impact on the sustainable development of the RN state, since the indicator is a function of sensitivity, exposure and status in relation to a level of damage. The model were presented as a tool to assist in indexing vulnerability in order to optimize actions and assess the implications of decisions makers and policies regarding the management of coastal and estuarine areas. In this context aspects such as population growth, degradation of vegetation, land use / land cover, amount and type of industrialization, SLR and government policies for environmental protection were considered the main factors that affect the eco-environmental changes over the last three decades in the Apodi-Mossoró estuary.

Análise de uso e cobertura do solo no município de Parelhas/RN

The human interference in the semiarid region of Seridó Potiguar has promoted the increase of degraded areas. The economic dynamic that was established in the Seridó territory, especially after the fall of the trinomial cattle-cotton-mining in the 70s and 80s of the 20th century as pillars of the regional economy, resulted in an accelerated process of erosion of natural resources. The municipalities of the Seridó region have been spatially reordered by this new economic dynamic, marked by the growth of existing enterprises, and the development of new agricultural practices. One of the municipalities in the region that restructured its territorial space with the emergence of new agro-industrial activities was the town of Parelhas. With the demise of the trinomial cattle-cotton-mining in the 1980s, other productive activities were intensified from the 1990s, amongst them, pottery, responsible for the vegetal extraction for use as energy source. This recent economic and spatial restructuring in the region, reflected in the Parelhense municipal territory, required new productive ingredients responsible for the modification of past production relations that were based on cattle, cotton and mining. By that a process of exploring the environment was unleashed, especially the native vegetation, in an uncontrolled manner. In this context, the objective of this study was to survey and detect deforestation in the areas of Caatinga vegetation, used indiscriminately as energy supply for new agricultural practices, using remote sensing techniques based on the quantification of the Normalized Difference Vegetation Index / NDVI, Soil-Adjusted Vegetation Index / SAVI, surface temperature and rainfall data in the years 1990 and 2010. The results indicated that SAVI values above 0.2 in 1990 and 2010 represent the areas with the highest density of vegetation that occur exclusively along the major drainages in the town and areas of higher elevations. The areas between the ranges of values from 0.5 to 0.15 SAVI are areas with poor vegetation. On the other hand the highest values of temperature are distributed in the western and southeastern parts of the township, usually in places where the soil is exposed or there is sparse vegetation. The areas of bare soil decreased in extension in 2010 at 11, 6% when related to 1990, this was caused by a higher rainfall intensity in the first half of 2010, but no regeneration of vegetation occurred in some places in the western and southeastern areas of the municipality today, due to the extraction of firewood to fuel the furnaces of industries in town

Atividade antiinflamatória de uma heterofucana da alga marrom Padina gymnospora

Fucans, sulfated polysaccharides extracted from brown algae and some echinoderms, have been extensively studied for its diverse biological activities and because of its interference with molecular mechanisms of cell to cell recognition, including leukocyte trafficking from blood vessels into sites of inflammation mediated by selectin, a family of adhesion molecules. In the present study, we examined structural features of a heterofucan extracted from brown algae Padina gymnospora and its effect on the leukocyte migration to the peritoneum. The sulfated polysaccharides were extracted from the brown seaweed by proteolysis with the proteolytic enzyme maxatase. The presence of protein and uronic acid contamination was detected in the crude polysaccharide extract. Fractionation of the crude extract with growing concentrations of acetone produced five fractions with different concentrations of fucose, xylose, uronic acid, galactose, glucose and sulfate. The fraction precipitated with 1.5 volumes of acetone was characterized by infrared and nuclear magnetic resonance, through which can be observed the presence of sulfate groups in the C4 of -L-fucose. The anti-inflammatory action of this composite was assessed by a sodium thioglycollate-induced peritonitis assay and through nitric oxide production by the peritoneal macrophages using Griess reagent. Fraction F1.5 was efficient in reducing leukocyte influx into the peritoneal cavity when 10 mg/kg and 25mg/kg were used, resulting in a decrease of 56 and 39%, respectively. A decrease of nitric oxide production occurred when high concentrations of fucana were used. The cytotoxicity of the composite was also assessed using the reduction of 3-(4,5 dimethylthiazol-2-yl) 2,5-diphenyltetrazolium bromide (MTT). Fraction F1.5 had no cytotoxicity when 500 μg/mL of the fraction was used. This study suggests the use of fraction F1.5 (heterofucan) as an anti-inflammatory

Análise caracterização da dinâmica da Foz do Rio Apodi, região de Areia Branca/RN, com base na cartografia temática multitemporal de produtos de sensores remotos

The study area islocated in the northern cost of Rio Grande do Norte State, preciselyin a west zone of Apodi-Mossoró River, inclunding Tibau City, Grossos City and part of Mossoró City. Geologicaly, this area is composed by rokcs of Potiguar basin, represented by Cretaceous, Tertiary and Quaternary sediments. This area is characterizer by the intense action of cosatal processes (eolic and costal tranports, generalized erosion, alteration in the sediments balance and coast modification), reponsable for it´s morfological instability, also the antropic interference, where the iol industry is located, next Mossoró City, and also the salt exploration industry and the tendency of expantion of shrimp cultivation. This report had as objective the multitemporalgeoenvorimentalmonitoring of the region by recognizingin the field and analizingimages of orbital sensors of diferents years of last four decades. This analisys was achieved by Digital Images Procesing (DIP) thecnics, com subsidized, in a GIS, the preparion of Thematic Maps of natural resources (Geology, Geomorphology and Use & Ocupatios of Earth) and the Envorimental Sensivity to Oil Spilling, main objective os this project. Such technics constitute important tools of envoriment monitoring and maneging, indicating tendencies of antropic of natural growing, making possible the apropiated planning of development of the region, where the steps can be indicated minimized possibles envorimental impacts caused by antropics interferencies on the region, mainly those related to industrial activities, and oil industry above all. Researchs of this nature are very important to the analisys and ordered manegements of use and ocupation of coastal places

Modelagem e desenvolvimento de um banco de dados geográficos : aplicação à elaboração de mapas de sensibilidade ambiental ao derramamento de óleo na área costeira entre galinhos e São Bento do Norte-RN

The area between Galinhos and São Bento do Norte beaches, located in the northern coast of the Rio Grande do Norte State is submitted to intense and constant processes of littoral and aeolian transport, causing erosion, alterations in the sediments balance and modifications in the shoreline. Beyond these natural factors, the human interference is huge in the surroundings due to the Guamaré Petroliferous Pole nearby, the greater terrestrial oil producing in Brazil. Before all these characteristics had been organized MAMBMARE and MARPETRO projects with the main objective to execute the geo-environmental monitoring of coastal areas on the northern portion of RN. There is a bulky amount of database from the study area such as geologic and geophysical multitemporal data, hydrodynamic measurements, remote sensing multitemporal images, thematic maps, among others; it is of extreme importance to elaborate a Geographic Database (GD), one of the main components of a Geographic Information System (GIS), to store this amount of information, allowing the access to researchers and users. The first part of this work consisted to elaborate a GD to store the data of the area between Galinhos and São Bento do Norte cities. The main goal was to use the potentiality of the GIS as a tool to support decisions in the environmental monitoring of this region, a valuable target for oil exploration, salt companies and shrimp farms. The collected data was stored as a virtual library to assist men decisions from the results presented as digital thematic maps, tables and reports, useful as source of data in the preventive planning and as guidelines to the future research themes both on regional and local context. The second stage of this work consisted on elaborate the Oil-Spill Environmental Sensitivity Maps. These maps based on the Environmental Sensitivity Index Maps to Oil Spill developed by the Ministry of Environment are cartographic products that supply full information to the decision making, contingency planning and assessment in case of an oil spilling incident in any area. They represent the sensitivity of the areas related to oil spilling, through basic data such as geology, geomorphology, oceanographic, social-economic and biology. Some parameters, as hydrodynamic data, sampling data, coastal type, declivity of the beach face, types of resources in risk (biologic, economic, human or cultural) and the land use of the area are some of the essential information used on the environmental sensitivity maps elaboration. Thus using the available data were possible to develop sensitivity maps of the study area on different dates (June/2000 and December/2000) and to perceive that there was a difference on the sensitivity index generated. The area on December presented more sensible to the oil than the June one because hydrodynamic data (wave and tide energy) allowed a faster natural cleaning on June. The use of the GIS on sensitivity maps showed to be a powerful tool, since it was possible to manipulate geographic data with correctness and to elaborate more accurate maps with a higher level of detail to the study area. This presented an medium index (3 to 4) to the long shore and a high index (10) to the mangrove areas highly vulnerable to oil spill

Análise multitemporal dos elementos geoambientais da região da Ponta do Tubarão, área de influência dos campos petrolíferos de Macau e Serra, município de Macau/RN

The study area is inserted in Ponta do Tubarão region, Macau City, setentrional littoral of Rio Grande do Norte State, composed of Tertiary and Quatemary sedimentary rocks and sediments. This region is characterized for the intense action of the coastal processes, causing the morphologic instability in part of the area, beyond the interference of human activities, as the Petroliferous Industrial Polo, salt companies and shrimp farms. This justifies the integration of multidisciplinary and multitemporal detailed scientific studies dealing with the evaluation of the changing behavior of this coastal environment by geoenvironments elements characterization, identifying protected and recuperation areas, mainly those under socioeconomic intervention. The main objective was the coastal monitoring using geoprocessing techniques to prepare thematic maps useful for oil spilling environment risk areas survey. The methodology was based on multitemporal interpretation of remote sensing images and field checking, integrated in a Geographical Information System (GIS). The Geologic, Geomorphologic, Vegetation, Soil and Land Use maps were prepared, and later on they allowed the generation of the Natural Vulnerability and Environmental Vulnerability maps. These maps had been classified in accordance with vulnerability degrees: very low, low, medi um, high and very high. Beyond these maps the GIS allowed the analysis of the shoreline evolution for 10 distinct dates, using Landsat 5 TM and 7 ETM+ and SPOT-HRVIR images. This analysis made possible the attendance of the coastal morphodynamic evolution, where the results had been represented by areasof erosion and accretion (or deposition) of sediments, pointing critical areas under erosive process to the petroliferous industry (Macau and Serra fields). The GIS also provided to prepare the Environmental Sensitivity Maps of Oil Spill (SAO Maps) in operational scale (1: 10.000), according to the norms ofthe Ministério do Meio Ambiente (MMA 2002). The SAO Map in operational scale was based on IKONOS images mosaic where the ESI (Environmental Sensitivity Index) was represented according with two tides phases of theregion. Therewere recognizedfiveESI (3, 4,7,9, 1O) for the low tide; to the high tide the ESI number increased to seven (3, 4, 5, 7, 8, 9, 10). All these information are necessary to the decisions making about oi! spill and its derivatives containment. These techniques application makes possible the optimization and implantation ofnew socioeconomics activities of low environmental impact, indicates areas for better productivity and security exploration, and benefits local communities with fauna and flora preservation. The development of these activities is inserted in the scope of Monitoramento Ambiental de Áreas de Risco a Derrames de Petróleo e Seus Derivados Cooperation Project (Rede 05/01 - PETRORISCO, FINEP/CTPETRO/PETROBRAS) of multidisciplinary and interinstitucional characteristics dealing with subjects involving the environmental monitoring and the petroliferous activity
