Problemas ambientais e relações de trabalho no Porto de Belém: perspectivas para um projeto de educação ambiental

Esta pesquisa mostra o olhar que trabalhadores e passageiros da Companhia das Docas do Pará – Porto de Belém têm do cotidiano do porto em relação aos problemas ambientais. Nossa motivação para o desenvolvimento deste estudo pautou-se na identificação de qual a situação ambiental na área portuária das Docas de Belém e se as ações de Educação Ambiental desenvolvidas em seu interior contribuem para a construção de melhorias socioambientais? Para a realização da pesquisa utilizamos como forma de análise a abordagem qualitativa, na qual buscamos priorizar não apenas a quantidade de dados referentes ao objeto de estudo, mas principalmente compreender o fenômeno em foco. No estudo desenvolvemos as seguintes etapas: a) levantamos dados sobre o entorno, destacando a ocupação urbana na área de influência do Porto; b) elaboramos um diagnóstico ambiental, por intermédio da visão de trabalhadores e usuários do Porto de Belém, visando suas expectativas quanto ao ambiente; c) Buscamos compreender o desenvolvimento de ações relacionadas à preservação ambiental, necessárias ao processo de educação para a sustentabilidade, desenvolvidas no Porto de Belém. Neste sentido, inicialmente realizamos uma ampla revisão da literatura sobre a temática, conjuntamente com a pesquisa documental, onde analisamos textos escritos por pesquisadores na área de meio ambiente, e da educação Ambiental, como: Loureiro (2004, 2009), Lima (2007), Silva (2009), Teisserenc (2010), Tapia (2005), Campanhola (2000), Gadotti (2008), Becker (2008), Antunes (2002). Assim como documentos oficiais relacionados ao meio ambiente e a outras iniciativas voltadas a Ações de Preservação e de Portos como: Constituição da Republica Federativa (1988); Decreto Lei 9.795 que dispõe sobre a educação ambiental, institui a Política Nacional de Educação Ambiental; Decreto Lei 8.630 que dispõe sobre o regime jurídico da exploração dos portos organizados e das instalações portuárias; Lei nº 8.630, de 25/02/1993 (antiga Lei dos Portos). A partir da construção do texto ampliamos nosso conhecimento, o que nos deu suporte teórico para iniciarmos a pesquisa empírica. Nesta etapa fizemos um levantamento da área edificada em parte da orla de Belém para identificar o percentual de ocupação urbana na faixa exclusiva selecionada, às proximidades do lócus da pesquisa, o levantamento realizado visou identificar alguma provável influência externa na área de movimentação de navios, o que foi descartado, pois o percentual de ocupação urbana (45,0830 %) encontrado foi considerado dentro dos padrões aceitáveis. Na segunda etapa do estudo foi feita a coleta de dados junto às pessoas que vivenciam o cotidiano da área portuária como: trabalhadores e usuários, objetivando obter informações sobre sua visão e opinião sobre o foco da pesquisa, utilizamos primeiramente a entrevista semiestruturada, objetivando esclarecer sobre as reais condições atuais do meio ambiente de trabalho, vivido cotidianamente por seus atores, nas questões profissionais, sociais e ambientais na área do Porto de Belém e, para que tivéssemos um diagnóstico do momento em que se encontra a ambientalização do Porto, realizamos entrevistas com sujeitos que trabalham diariamente naquele ambiente portuário. Culminando o estudo, utilizamos questionários, os quais foram aplicados a 80 (oitenta) sujeitos trabalhadores e 149 (cento e quarenta e nove) aos usuários/passageiros. O resultado da pesquisa revelou como principais problemas apontados, tanto pelos usuários como pelos trabalhadores os impactos ambientais causados pelas atividades portuárias como a emissão de resíduos sólidos, líquidos, derrame de produtos perigosos e os riscos de contaminação do rio. Assim como lixo em excesso e sua coleta indevida, que tem ocasionado frequentes entupimentos dos esgotos. Assim como a inexistência de continuidade do trabalho de limpeza e manutenção com a prática necessária da dragagem retirada de entulhos do rio e do canal das docas. Constatamos também, que existe a intenção pela gestão da CDP em realizar o trabalho de utilização correta de sistemas de carga e descarga, armazenagem, pesagem, acomodação e movimentação de cargas no porto, bem como realizar de forma correta controle de matérias que chegam e que saem, e que é perceptível a eficiente vigilância da movimentação na área de embarque e desembarque de passageiros, o fazem com que o Porto de Belém permaneça dentro dos padrões estabelecidos na Constituição, o processo de gestão portuária ocorre regularmente obedecendo a um sistema de atividades previamente determinadas e que se encontram de acordo com a Lei dos Portos. O grande ganho que se observa no estudo e esclarecimento das questões investigadas é a apresentação do conceito que os atores envolvidos têm da realidade ambiental existente.

Evaliação do impacto do programa de coleta seletiva de lixo na frequência de Calliphoridae e Muscidae em Tupã-SP

Este trabalho discute o uso da análise de frequência de moscas das famílias Calliphoridae e Muscidae na avaliação do impacto da implantação de programas de coleta seletiva de lixo urbano. Para isto, utilizou-se do estudo de caso de Tupã, município paulista, em duas fases distintas: fase 1 - compreendida entre os meses de junho e outubro de 2001, período caracterizado pela presença do lixão e; fase 2 - entre os meses de novembro de 2001 a maio de 2002, caracterizada pelo início da implantação do processo de coleta seletiva e reciclagem e aterramento gradativo do lixão. Procedeu-se a captura dos insetos com dez armadilhas confeccionadas com garrafas plásticas, de dois litros, do tipo PET, alocadas em residências e árvores ao redor do lixão. Como atrativo utilizou-se aproximadamente 400 ml de vinhaça de cana de açúcar, substituída semanalmente no ato da colheita. Nas duas fases da pesquisa, observou-se que a família mais frequente e constante foi a Calliphoridae.  Houve correlação positiva, antes da coleta seletiva, entre o número de califorídeos e a precipitação pluviométrica (0,638) e, entre o número de muscídeos e a temperatura média (0,605). Após a coleta, o mesmo não foi observado. O programa de coleta seletiva implantado nesse município paulista resultou em diminuição significativa na frequência de dípteros e a análise da flutuação de califorídeos e muscídeos demonstrou-se como um eficiente indicador de monitoramento da qualidade ambiental.

Identifying problems for choosing suitable areas for installation of a new landfill through GIS technology: A case study

Selecting a suitable place to install a new landfill is a hard work. Bauru is a Brazilian municipality where the local landfill currently in use has a life span that is almost over, and the selection of a new area for a future landfill is crucial and urgent. Here we use a geographic information system (GIS) approach to indicate possible suitable areas for installing the landfill. The considered criteria were: river network and the respective buffer zone, relief, urban areas and their respective buffer zone, existence of Areas for Environmental Protection (AEPs), occurrence of wells and their respective buffer zones, existence of airports and their buffer zones, wind direction, and the road network and its respective buffer zone. Due the facts that (1) Bauru has an urban area relatively large in relation to whole municipal area, (2) Bauru has two airports, and (3) this area encompasses parts of three AEPs, the model showed that there are few areas suitable and moderately suitable in Bauru, and the greater part of the municipality is unsuitable to install a new landfill. Due to this important finding reported here, the local policymakers should consider the suitable or even moderately suitable areas for analysis in situ or look for other creative solutions for destination of the solid waste. We highly encourage the use of GIS in studies that seek suitable areas for future landfills, having found that SIG was a tool that allowed fast and precise work and generated an outcome sufficiently clear of interpretation.Implications: Solid waste (SW) management is one of the main environmental concerns nowadays. Landfilling SW is still the main practice to disposal of such material. However, for many regions, suitable places for landfilling are getting scarce. This study proved this situation for a populous place in a southeastern Brazilian region. This study also showed how the decision makers should manage the problem in order to minimize the amount of SW generated and delivered for the landfill. Massive investment in education is a critical issue to reach the proposed aim.

Análise das centrais de triagem do programa de coleta seletiva da cidade de São Paulo - SP

Among numerous studies about the selective collection of solid waste and cooperatives of recyclable materials, this research aims to contribute with the study of these problems from the geographic space. As the world population increases, the issue of solid waste becomes increasingly worrying, due to new consumption patterns that create larger amounts of waste, especially in the urban centers. The recycling appears to be the best solution for this problem since most materials that are currently sent to landfills would become raw material for new products. The Triage Centers performs an important role in this process because they are responsible for sorting, packing and selling the materials arising from the selective collect, so it is necessary to analyze the places where these steps are performed. This study intend to examine the location and distribution of these enterprises in the city of São Paulo in order to provide support for the mitigation of impacts, both environmental and social, from their location, as well as provide support for the expansion of selective collection program in the city. The choice for studying this area was due to the curiosity of investigating the inefficiency of the recycling program in the city of São Paulo, which currently recycles about 1% of all household solid waste collected. Therefore, from a historical survey of the city's recycling programs, technical visits, interviews with responsible agencies and also analysis of the Triage Center's frameworks based on the guidelines from the municipal legislation, it will be evaluated the problems faced by the program for its expansion

Diagnóstico da gestão e do gerenciamento dos resíduos eletroeletrônicos gerados no campus da Faculdade de Engenharia de Guaratinguetá/Unesp

Currently, in Brazil, the quantity and quality of new types of wastes, discarded without criteria in urban areas, has been responsible for considerable impacts on public health and the environment. According to a report prepared by the Institute of Applied Economic Research (IPEA), the country loses about U.S. $ 8 billion annually, due lack of waste recycling, which go directly into landfills or dumps. Among these solid wastes are waste electrical and electronic equipment (WEEE), whose characteristics are complex, by having in its composition substances of high value-added and other health hazards which require different treatment of household waste. Aiming to fill the gap in Brazilian environmental legislation, on 02/08/2010, was sanctioned the National Policy Solid Waste (Law No. 12,305), already regulated on 23/12/2010 (Decree No 7404), whose based on the following principles:reduction of waste generation and toxicity of shared responsibility, proper planning management, social inclusion of waste pickers and sustainable production and consumption. Given the above, this work presented here, aims generally present a diagnosis of the current situation of electronic waste generated in the Faculty of Engineering, Campus Guaratinguetá, FEG / UNESP, to provide data for management and management of these waste, based on sustainability, the economic losses and minimizing environmental impacts and public health related to the flow and the improper disposal of these wastes

Cooperviva: análise das possibilidades e limites do trabalho dos catadores de resíduos recicláveis de Rio Claro (SP)

The issue of waste, historically, has been getting worse as a result of the world´s population increase and in order to meet their needs the consumption of natural resources and the generation has been constantly increasing, especially in large urban centers. The people involved in the collection of recyclable solid waste, called from now on as collectors, are responsible for about 90% of the waste sent to recycling industry in Brazil. Apart from having a role in the economy, the collectors have specific knowledge and skills necessary to identify, collect, sort and sell these wastes. This study aims to examine the possibilities and limits of COOPERVIVA – Cooperativa de Trabalho dos Catadores de Material Reaproveitável de Rio Claro - as an instrument of the municipal solid waste management system, and its experience as a recyclable waste collectors cooperative. The methodological procedures of this study rely on the literature research on the experiences of cooperative and the management of municipal solid waste. In addition to this review of the literature, fortnightly visits to the cooperative were held in order to experience their daily activities, and testimonies of the cooperative members were collected as well as documents and reports produced by COOPERVIVA. The results of this analysis are considerations of the limitations of the cooperative and recommendations aimed at maximizing their potential as a tool of the domestic solid waste management system of and as a recyclable waste collectors cooperative. Among other things it can be concluded that the urban selective collection of waste challenges the community to the reinvention of life and the relationships each individual with the planet.

Geofísica aplicada no diagnóstico preliminar do antigo lixão do município de Rio Claro - SP

The issue of solid waste disposal and urban growth are conflictive, since the areas where old uncontrolled refuse disposal were away from the city today are incorporated to the urban area population. Thus, now population is closer to the degradation of contaminants coming from waste disposal, and, in some cases, these areas become housing subdivisions. This work aims to support the diagnosis of a former landfill in the municipality of Rio Claro (SP), using geophysical methods through resistivity anomalies. In order to develop the diagnostic, it was utilized water and soil analysis of a preliminary report and techniques of vertical electrical sounding and electrical profiling. The areas influenced by the garbage presented less resistivity than the one of the natural subsoil. Through the interpretation of results, the local potentiometric map was elaborated, as well as a map of calculated resistivity. The interpretation of these products indicated a disagreement between the groundwater flow and the current topography, leading to an identification of a preferential direction of the contamination plume in the NE-SW. These observations prove the applicability of geoelectrical methods in areas of former waste disposal with little information.

Condições mínimas para o encerramento de áreas que abrigaram resíduos sólidos domiciliares

In 2010 Brazil produced about 60.8 million of municipal solid waste, an amount 6.8% higher than in 2009 and six times the rate of urban population growth recorded in the same period. According to a study by the Brazilian Association of Companies of Special Wasteand Public Cleansing (Abrelpe), the average waste generated per person in the same period the country was 378 Kilograms, an amount 5.3% higher to 2009 (359 Kg). The total reached 60.8 milion tons of waste, 6.5 million tons were collected and not end up inrivers, streams and vacant lots. Of this total production, 42.4% or 22.9 million Tons, did not receive proper destination and destiny had dumps and landfills. The data show that the country is in upward trend in waste generation, but did not advance the appropriate destination at the same pace. The waste thus throw open cause public helth problems, such as proliferation of disease vectors (flies, mosquitoes, cockroaches, rats, and others). Generation of odors and especially the pollution of soil, surface water and groundwater through slurry ( liquid black, smelly and high pollution potential produced by the decomposition of organic matter contained in waste), affecting the water. This Study shows the popper closure of the areas, wich long has been degrading our natural resources, not to cause damage to nature and therefore society

Degradação ambiental e qualidade de vida na microbacia do Córrego do Gramado – Presidente Prudente/São Paulo

The late industrialization, together with other factors, ended up directing much of the rural population to cities, without adequate planning, resulting in high density and irregular settlements in risk areas to low-income population. The man settled in the urban site to break environmental laws that eventually causing an imbalance in the natural environment, causing or exacerbating the shortage in availability of water resources. This situation also happened in Presidente Prudente, especially in the east, the focus of this research. Therefore, this study aims to understand the causes of degradation of waterways in urban areas, focusing on society's relationship with nature and its consequences on environmental quality and quality of life of urban population located in the watershed of stream of Gramado, Presidente Prudente - São Paulo. In this catchment there is the irregular deposition of solid waste in the valley, remnants of old pollution release of domestic sewage and industrial (currently collected and intended for treatment), accelerated processes of erosion in some areas of intensive use of the relief and consequently, the bed siltation of streams that are part of the basin. The quality of urban life was seen through socioeconomic and environmental indicators, which were identified through questionnaires to residents, according to local residence in the landscape, divided into three segments: the tops 60 residents, 90 residents and 112 residents in the areas in valley bottoms. With these data we can relate them to the degradation of the basin and aggregate them to the quality of life of residents. Field studies were needed to visualize the changes that occurred in the watershed over the past three years, with the implementation of works aimed at improvements to the community as the conduit stream of Gramado and construction and operation of Sewage Pumping Stations...

Diagnóstico dos resíduos de construção e demolição: uma contribuição à elaboração e implantação da gestão integrada dos RCD no município de Guaratinguetá – SP

The problem of solid waste has caused discussions about the huge amount that is generated in Brazilian cities, in particular the waste from construction and demolition (CDW), called spoil. In many cases these wastes are disposed of improperly and even criminally in urban areas, causing serious economic, social and environmental problems. Due to the lack of public policies and appropriate management of such waste came up with the CONAMA, in its resolution nº 307 of 2002, the obligation of municipalities in deploy the integrated management of construction and demolition wastes for the resolution of problems caused by inadequate management and disposal of such waste. By following a methodology suggested by Pinto & González (2005), with adaptations of other authors, it is proposed in this work the lifting of a diagnosis of the CDW in the municipality of Guaratinguetá-SP, through theoretical analysis and field research, with purpose to guide the public servants in the elaboration and implementation of integrated management. The results must contain information necessary for that end, such as the knowledge of generators, agents, collectors and transporters, disposition areas and the disposal of waste
