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

A incorporação de preceitos ambientais no sistema de gestão de resíduos sólidos do município de João Câmara - RN Brasil

The reality points to the global environmental sustainability as the only viable option for addressing the crisis at hand. The move towards sustainability calls for the generation / evaluation systems in their direction, through the incorporation of environmental requirements and in line with the National Policy on Solid Waste. Therefore, the proposed research supports the importance of social and environmental vision, complementing the technical view, the system for management of solid waste from East London, which is a municipality that has a system whose inadequacies are configured in environmental risk and health. Therefore, by observing, applying the model of sustainability indicators and content analysis of interviews, this research proposes to investigate the principles of sustainability and social participation are presented and what is the perception of risk about the inadequacies in the system. The results confirmed the hypotheses of the study and draw a picture of worrying data, such as very unfavorable indicators of sustainability, lack of channels of participation, uncommitted investments with the management system, devaluation of the collector of waste and differing perceptions about the risk by making actors act in isolation. This worrying situation is eased by the appearance of a series of elements are configured as opportunities for the integration of environmental principles in the system. And despite the inability of managers to participate in the research system, yet it behaves as an opportunity to implement public policies in the area of solid waste such as: the preparation of the municipal waste, the institutionalization of selective collection and organization of cooperative with the support of companies present in the city and educational institutions as the Federal Institute. The research is an opportunity for the implementation of policies in the area of solid waste and will collaborate with the building instruments for the quality of life of residents, for the socioeconomic conditions of collectors and the move towards a sustainable society

Gestão dos resíduos sólidos no Brasil e seus rebatimentos em Natal, Brasil

O artigo apresenta a gestão dos resíduos sólidos no Brasil e seus rebatimentos na cidade de Natal/RN, verificando seus aspectos ambientais, econômicos e sociais. O fracasso da coleta seletiva revelado nos baixos índices de recuperação dos materiais; a baixa relevância da inclusão socioeconômica dos catadores que participam do programa assistencialista oficial; a inexistência de estratégias oficiais para que se minimize a quantidade de resíduos que se gera cada dia e o aumento exagerado dos gastos públicos, sobretudo com o tratamento dos resíduos no aterro sanitário, demonstram que a gestão de resíduos em Natal, conforme parâmentros da Política Nacional de Residuos Sólidos, objetiva o controle destes na cidade e a consolida- ção do tratamento finalista através do envio da quase totalidade dos resíduos coletados ao aterro sanitário

Similitudes na gestão dos resíduos sólidos urbanos em países centrais e periféricos

A emergência na necessidade de se manejar os resíduos sólidos urbanos leva as administrações públicas em países centrais e periféricos a utilizarem modelos de gestão de resíduos bastante similares. A gestão dos resíduos nos países centrais é caracterizada pela eficiência na execução dos serviços (limpeza, coleta, transporte e destino final), uso de aparatos tecnológicos na execução de ditos serviços e forte tradição na separação dos materiais recicláveis a ser destinados para a reciclagem. Nos países periféricos, a gestão tradicional (coletar e descartar resíduos em lixões à céu aberto) vem sendo substituída pela gestão moderna, sobressaindo-se o controle dos resíduos em detrimento das estratégias de prevenção. Também, destaca-se a presença de trabalhadores informais que coletam e separam materiais, destinando-os à reciclagem. A partir do levantamento à referência bibliográfica especializada e na consulta a documentos oficiais e produzidos por entidades diversas, o presente artigo analisa as similitudes na gestão dos resíduos sólidos em países centrais e periféricos. A busca pela modernização nos serviços dos resíduos sem levar em conta as recomendações de documentos como a Agenda 21 caracteriza a gestão dos resíduos em países centrais e periféricos pelo ambientalismo econômico, no qual as ações de controle dos resíduos são justificadas pelos aspectos ambientais e sociais dessa gestão

Desenvolvendo e gerenciando compostagem de resíduos sólidos urbanos: para geração de renda e repasse de tecnologia à acrevi

Nowadays, as well as in the past decades, the dumping of biodegradable organic waste in landfill is common practice in Brazil, as well as in most parts of the world. Nevertheless due to its rapid decomposition and release of odors, this practice hamper’s the operation and implementation of a recycling system. These facts encouraged our research to find an efficient system for the management of organic waste, not only for the use of official workers responsible for managing these wastes, but also for non-governmental institutions. The Recycling for Life Community Association – ACREVI (Associação Comunitária Reciclando para a Vida), together with the municipal authorities of Mossoró-RN, Brazil, have assumed the social role of collecting and recycling solid waste produced by most of the local population. However, it was observed that the organic waste it collected was not receiving any treatment. This present work aims to make compost with mixed waste (green waste and organic household), and then do chemical analysis of the material in view to use the waste as organic fertilizer. The objective being: to share the knowledge acquired by putting it into a very simple language accessible to people with little education. The experiment was conducted at ACREVI, Mossoró (RN), and the compost was obtained following the method "windrow", forming three cells (I, II, III) with conical shape, dimensions of 1.6 meters and 2.0 meters in diameter for cells I and II, and 1.0 meters high and 2.0 meters in diameter for cell III. The process was accompanied by analysis: CHN elemental, a variation of cell temperature, humidity, pH, TKN, bulk density, nutrients and heavy metals. Stabilized organic compounds reached the C/N ratio of 10.4/1 cell I and 10.4/1 in the cell II in the cell, showing how good soil conditions, with potential to improve the physical properties of any soil and pH acid soils, has presented the cell III at the end of the process the C/N 26/1, is a high ratio may be associated with the stack size III, thus changing the optimal conditions for the occurrence of the process. The levels of heavy metals in the analyzed compounds were lower than those established by the SDA normative instruction, Nº 27, of 5 June, 2006. The use of pruning trees and grass are used in small-scale composting, while generating a quality compost in the final process, it also created an important condition for a correct sizing of the composting piles. Under the studied conditions it is not advisable to use cells with a height of 1.00 m in height and 2.00 m in diameter, as these do not prevent the rapid dissipation of heat and thus can not be a good product at the end of composting. The composting process in the shed of the association and the preparation of the primer enabled the development of an alternative technology to generate income for members of ACREVI.

Teor de flúor na água de poços superficiais

Most of the water supplies in Brasil have a low Fluoride concentration, however there are some places where these concentrations are above the recommended as suitable for human consumption, causing chronicle intoxication, more specifically, dental Fluorosis. This study aimed to know the Fluoride content naturally present in water from 175 shallow wells located in the rural zone of Gabriel Monteiro city, in São Paulo state, in 2004, and to verify if these contents could prevent dental decay. Armed with a map of the city were located and visited all households in which a sample of water used was collected in a polyethylene bottle, then sent to NEPESCO (Collective Health Research Nucleus) laboratory of the Post-Graduation Program of Preventive and Social Dentistry of the Ara atuba Dental School-UNESP, The method used was the Fluoride ion-specific electrode (Orion 9609 BN), coupled to an ion-analyzer (Orion 710 A). The results showed that in 73.36% of the samples in the Fluoride concentrations was considered despicable (<0.10 ppm F). The Fluoride concentration in water sources do not exceed the values recommended by Brazilian legislation, however, considering the low concentrations of Fluoride found in the sources analyzed, it is important to recommend the use of Fluoride products, if used with proper care, aiming to promote oral health in this population.

Modificações químicas em solo solarizado, com e sem incorporação de resíduos orgânicos

The soil solarization is used in small properties as an alternative for control of phytopathogens and weeds, besides it also can affect the availability of some nutrients and phytotoxic elements in the soil. Thus, one experiment was carried out as a three-factor factorial (solarized and not solarized soil x with and without addition of vegetable residue x four collection times) for evaluation of variations of pH, organic matter, phosphorus, total nitrogen, potassium, calcium, magnesium and aluminum in a soil characterized as Distrofic Red Latosoil, in Botucatu county (SP). The incorporated vegetable residue was constituted of crop remains of kale (Brassica oleraceae var. acephala L.) fresh and triturated. Soil samples of each treatment were collected from zero to Urn of depth, at 7, 21, 35, and 49 days after solarization treatment, from January to March of 2001. Soil chemical analyses were done as well as the soil temperature were monitored on the treatments. The solarized soil with kale organic residues addition treatment presented higher values of pH, organic matter, total nitrogen, phosphorus, potassium, calcium, magnesium and minor values of aluminum.

Distribuição e biodisponibilidade de crômio em solos contaminados por resíduos de couro

DISTRIBUTION and BIOAVAILABILITY of CHROMIUM IN CONTAMINATED SOILS BY TANNERY RESIDUES. Samples of soil, water and sediment were collected and analyzed in order to evaluate chromium contamination due to deposition of tannery residues onto soils under different management regimes. The results showed that soils used for sugar cane cultivation were not adversely impacted. However, in the case of mango plantations, variable concentrations of chromium were measured in the soil profile, with 22.2% of values being higher than permitted legal limits, and 38.9% being at levels requiring remediation. Concentrations of bioavailable chromium were lower than the detection limit of the method (0.01 mg of chromium kg(-1) of soil), indicating that all of the chromium present in the samples was either complexed or in an insoluble form. Chromium concentrations measured in samples of water and sediments were indicative of low mobility of the metal in soils. The main cause of differences found between soil samples obtained from different cultivations was the type of soil management.
