A saúde ambiental e os resíduos de serviços de saúde nos três níveis de complexidade do Sistema Único de Saúde - SUS

The environmental management in the health establishments is a reality still little explored in the health sector in Brazil, especially concerning its wastes. The management of wastes of health services is established in the valid legislation through the National Council of Environment and Sanitary Vigilance Agency (358/2005 and 304/2004 respectively). The present work is about a descriptive work about the environmental health in the health services. The used criterion was to diagnose the environmental management in twelve establishments of health inserted in the three levels of complexity of the Unique Health System (Sistema Ùnico de Saúde SUS). Among the sub criteria used the waste management is the one of bigger concern. The one referring to the water quality is considered good. The analysis of data reveals that 66% of the establishments got a poor environmental ranking, 17% critical and 17% appropriate, showing that the health establishments in the three levels of complexity of the SUS need urgent structural, environmental and educational interventions

Em busca do estado participativo: os desafios da participação social na gestão ambiental

The existence of several negative indicators such as deforestation, pollution of rivers and urban growth disorderly suggest a scenario of serious environmental degradation in Brazil, allowing that the model of public management of the environment here is not practiced efficiently, despite to be a recognition-of environmental legislation as one of the best and most comprehensive in the world. One of the main causes of this problem is the low social participation in environmental management that often exists only in the formal plan. Thus, although defined as Democratic State, in practice, it is only a Figurative State. Based on the study of the origin of the state and social participation in the Brazilian State, in general scope, and some environment committees and public hearings in Rio Grande do Norte, as instruments of social control, in particular scope, it is possible to build a real Democratic State in environmental management, a Participative State, in which all players are aware of the responsibility and committed to the duty assigned to them by the constitutional text with the present and future generations

Análise da degradação ambiental das áreas de preservação permanente localizadas no estuário do rio Ceará-mirim/RN

The purpose of this paper is to identify and analyze the main environmental impacts taking place in the permanent preservation areas located in the Ceará-Mirim River estuary/RN and its surrounding areas. For that, the study was divided in two chapters, structured in the shape of a scientific paper. The first is a theoretical proposition on the occupation of the APPs in light of the discussion of the geographic space and the sustainability of the development, where a bibliographical review was made emphasizing the production of the geographic space, the sustainability of the development and the permanent preservation areas. In the second chapter, from a systemic approach, geoprocessing techniques and the adaptation of the Pressure-State- Response Indicators System were used, the latter being developed by the Organization for Economic Co-operation and Development OECD. Therefore, from the methodological approaches used, it's been observed that the use of permanent preservation areas for purposes other than those determined in the legislation and, mainly guided by capitalist interests, leads to the environmental degradation of these areas, fact which has been confirmed in the empiric study conducted in the second chapter, where it was possible to identify a series of environmental impacts such as: deforestation of mangrove and riparian vegetation for carciniculture implantation, the devastation of dune areas caused by the urban expansion in the coastal stretch and siltation of fluvial channel

Educomunicação: uma estratégia para promover o ambiente em uma área de proteção ambiental costeira

This study aimed to evaluate the potential of two public schools in Educommunication related to Environmental Protection Area Jenipabu (APAJ) located in Rio Grande do Norte / Brazil, based on perceptions of educommunicatives practices on the environment as well as perform an action included in the school APAJ. In the first phase of the research were three separate questionnaires designed to identify the actions, practices and experiences of three sets of audiences: teachers, students and parents from both schools. In the second phase, activities were carried out as educomunicatives class actions involving ride, maps of environmental design and construction of a mural on the school newspaper APAJ. We opted for the participant, making the observation in a previous visit to knowledge of the schools, where they made the first contacts with the administrative team, teachers and students, and then the application of semi-structured questionnaire to teachers, students and parents of the 4th and 5 years of elementary school the morning hours. The results showed the detachment of these actors in the knowledge, participation and involvement with APAJ, caused by the absence of actions and actions involving teaching practices educomunicatives students to interact with the environment, taking as its starting point the living space.

Análise da toxicidade no açude Riacho da Cachoeira, Lajes Pintadas (RN): um desafio interdisciplinar

Contamination by complex mixtures of various origins has been explored and studied for decades. Radon is a naturally occurring environmental contaminant that causes carcinogenic effects. These emissions can cause mutations in the lung tissue, which can initiate a carcinogenic process. Thus the dam Creek Falls, located in the municipality of Lajes Pintadas, was chosen for the development of this study, since cancer rates in the region reach 9% of the population annually, with this, the main objective of this study was evaluate the mutagenicity and toxicity of Riacho da Cachoeira damunder the influence of radon. The methodology ecotoxicological tests were performed with Ceriodaphinia dubia, as well as tests with Tradescantia pallida genotoxicologicos and Oreochromis niloticus. To understand how the population of Pintadas Slabs realizes the environment, we performed a study of environmental perception. The test results indicated that the reservoir water is toxic to test organimos exposed, found heavy metals, chloride, total and fecal coliforms as well as radon levels above the maximum allowed under Brazilian law. These results can be justified because it is so complex samples composed of different compounds that interact only with each other or causing synergistic effects. It was concluded that the dam Creek Waterfall, is contaminated with radon, as well as heavy metals, coliforms and chloride, causing toxic effects to the natural community. Thus, further studies should be performed with the human population of the region, to verify that the high rates of cancer in the population of the municipality may be linked to the presence of natural radiation. Thus, it is expected that the competent bodies that administer the municipality of Lajes Pintadas take reasonable steps to minimize risks and ensure the health of the community that still makes use of the weir

Revitalização do Rio Golandim (RN/Brasil) após décadas de contaminação por efluentes industriais e domésticos: este rio está recuperado?

Environmental pollution causes the loss of the quality of aquatic resources and also affects the health of human beings. The Golandim River is located in São Gonçalo do Amarante (RN Brazil) and had its water recovered seven years ago by measurements of parameters of the water s quality analyses physicochemistry, microbiological and heavy metals. However, it is not well established if this river is truly recovered, so this study provides a wide knowledge about the quality of these waters. Therefore, this investigation was accomplished by assays of ecotoxicology utilizing Ceriodaphnia dubia and of genotoxicity of the river s water using a biomarker Tradescantia Pallida (Trad-MCN). In set, it carried through a study of environmental perception through questionnaires that approached questions related to the profile of the interviewed one, knowledge on the environment and of the river Golandim with the community that lives in the neighborhoods of the river to diagnosis as they perceive the environment where live and its problems. The assays of the water had been carried out by collecting samples in three different sites of the Golandim River. They were collected between the periods of December 2010 (dry season in the northeast of Brazil) and July 2011 (rainy season in the northeast of). The analysis of the data allowed observing that the majority of the inhabitants are adult and presents a global vision of what it is part of the environment, the majority mentions the pollution of the river as one of the problems of the city, considering it serious. The ecotoxicology assay showed that there was not acute toxicity in all three samples collected. Meanwhile, all these three samples demonstrated significant chronic toxicity. The results from the Trad-MCN assay presented an increase in the frequency of micronucleus in one of the sites analyzed (S3) (p<0.01), in both seasons collected. On the other hand, the sites S1 and S2 did not presented a significant increase of micronucleus using this bioassay. The analyses of chemicals detected an increase in the levels of some metals, in different seasons and samples, which can be associates with some compounds found in urban and industrial areas. On the other hand, the physicochemistries parameters demonstrated that the Golandim River is recouped, when compared with the values presented at the CONAMA s legislation. However, these results indicate the presence of compounds capable of inducing chromosomal mutation in plants. On the other hand, the parameters physicistchemistries demonstrate that the river Golandim is if recouping, since when compares the values observed with the legislation of the CONAMA. All these results point to the fact that the Trad-MCN assay was sensitive and efficient biomarker for chromosomal instability and the C. dubia ecotoxicology assay was as though an efficient biomarker of toxicity of water s quality. The results from Trad-MCN associated with the ecotoxicology demonstrates that these analyses are important for environmental monitoring, once the first bioassay described above indicates alterations at the standards of cells and the other one indicates alterations at the standards of organisms. This study alerts for the necessity to carry out biological assays for the analyses of the water s quality

Análise da transformação do uso da terra, vegetação e impactos ambientais por meio de sensoriamento remoto e geoprocessamento

The mapping of the land use, vegetation and environmental impacts using remote sensing and geoprocessing allows detection, spatial representation and quantifying all alterations due to the human action in the nature, contributing to the monitoring and planning of those activities that cause damages to the environment. The aim of this research is analyze the transformation ocurred with the land use and vegetation in order to detect environmental impacts during the period from 1962 to 1995, considering a test area in the district of Assistência and surroundings, in the Rio Claro (SP) region. In order to archieve such aim the authors used boolean operations available in the Geographical Information System (GIS) - Idrisi. The maps were obtained through the ordinary (conventional) interpretation of aerial photos, later digitized in the software CAD Overlay and georeferenced in AutoCAD Map. It's observed that operations such as crossing digitized maps of one specific area in two differents dates, using GIS, produce overall results that might point out expansion or retraction's trends of the mapped classes, as well as quantify the intensity of the phenomena.

Mapeamento do uso da terra, vegetação e impactos ambientais por meio de sensoriamento remoto e geoprocessamento

The mapping of the land use, vegetation and environmental impacts using remote sensing ana geoprocessmg allow detection, spatial representation and quantification of the alterations caused by the human action on the nature, contributing to the monitoring and planning of those activities that may cause damages to the environment. This study apply methodologies based on digital processing of orbital images for the mapping of the land use, vegetation and anthropic activities that cause impacts in the environment. It was considered a test area in the district of Assistência and surroundings, in Rio Claro (SP) region. The methodology proposed was checked through the crossing of maps in the software GIS - Idrisi. These maps either obtained with conventional interpretation of aerial photos of 1995, digitized in the software CAD Overlay and geo-referenced in the AutoCAD Map, or with the application of digital classification systems on SPOT-XS and PAN orbital images of 1995, followed by field observations. The crossing of conventional and digital maps of a same area with the CIS allows to verify the overall results obtained through the computational handling of orbital images. With the use of digital processing techniques, specially multiespectral classification, it is possible to detect automatically and visually the impacts related to the mineral extraction, as well as to survey the land use, vegetation and environmental impacts.
