Simulação da dispersão de poluentes atmosféricos e avaliação da qualidade do ar na área de abrangência do Distrito Industrial de Barcarena-PA

A poluição atmosférica é considerada atualmente um dos maiores problemas da sociedade contemporânea, por ameaçar sua qualidade de vida, pois gera impactos negativos no meio ambiente natural e antrópico. Dentre as formas de controle da poluição atmosférica de fontes fixas podem-se destacar a diluição das emissões na atmosfera devido aos efeitos de dispersão, a adoção de equipamentos de controle antes do lançamento dos gases ou a realocação de fonte, visto ser uma possibilidade a ser sugerida durante o procedimento de licenciamento ambiental de empreendimentos com potencial poluidor do ar. Atualmente modelos computacionais de dispersão de poluentes na atmosfera vêm sendo amplamente utilizados na simulação da concentração de poluentes, visando auxiliar órgãos ambientais no prognóstico da qualidade do ar ou suprir deficiências de monitoramento de emissões atmosféricas. O presente trabalho estudou a qualidade do ar e avaliou a dispersão de poluentes atmosféricos sobre Vila do Conde e áreas de influência do Distrito Industrial de Barcarena, no município de Barcarena, estado do Pará, com auxílio do modelo AERMOD View, visto a possibilidade de se estabelecer uma relação entre os níveis de emissões dos poluentes na fonte, com as concentrações dos mesmos no ar, bem como identificar pontos críticos de poluição. O Índice de Qualidade do Ar – IQA e as fragilidades das populações humanas das áreas afetadas pelos poluentes atmosféricos, também foram mensurados na pesquisa. A metodologia empregada permitiu mensurar a concentração média de poluentes atmosféricos durante um determinado tempo de modelagem, informações quanto ao alcance da pluma de poluentes foram alcançados também. São fornecidos ainda informações quanto à relação entre o valor de pico e o valor médio da concentração nas áreas receptoras, provocadas por empreendimentos com características operacionais similares ao modelado. Os resultados demostram que a influência de parâmetros meteorológicos, na dispersão de poluentes são indispensáveis e determinantes na previsão do impacto na qualidade do ar e no planejamento do uso e ocupação do solo de áreas que abrigam atividades poluidoras da atmosfera.

A importância da definição das áreas de influência(AI's) no licenciamento ambiental para a sociedade - estudo de caso: as minas de caulim no município de Ipixuna do Pará-PA

A pesquisa sobre a relevância da definição de áreas de influências (AI) para a sociedade, abordou sobre Estudos de Impactos Ambientais (EIA‟s) de empreendimentos de extração mineral. Foram analisados 11 (onze) Estudos de Impactos Ambientais protocolados na Secretaria de Estado de Meio Ambiente – SEMA, envolvendo a dé-cada de 1990 a 2000, além de legislações e literaturas especializadas. Para tanto, foi abordado à mineração no Estado do Pará e o processo de licenciamento ambien-tal, definição das áreas de influência em projetos de mineração e criação de seis critérios, específicos para esta dissertação, visando a avaliação da AI‟s apresenta-das nos 11 EIA‟s, para o meio antrópico. Os resultados da análise levaram a detec-tar as razões que confirmam a relevância das AI‟s, assim como suas implicações associadas à qualidade do EIA/RIMA e sua funcionalidade para a sociedade. Bus-cando subsídios que fortalecessem o argumento defendido sobre a relevância das AI‟s, foram realizadas trabalhos de campo nas minas de caulim. As referidas minas já se encontram em funcionamento há mais de 10 anos, e foi possível perceber al-gumas mudanças ocorridas em suas AI‟s. O resultado do campo, confirmou a análi-se realizada nos 11 EIA‟s, pois foi evidente detectar que a decisão para selecionar e definir as AI‟s, apresentados nos EIA‟s objetivando o licenciamento das minas de caulim, desencadeia conseqüências para a sociedade local que pode influenciar ao longo da vida útil do projeto licenciado. Assim, desperta-se a necessidade de elabo-ração de estudos científicos que sejam capazes de contribuir com metodologias es-pecíficas de definição de AI‟s para a região amazônica e com isso, tratar o processo de licenciamento ambiental a partir de legislações direcionadas ao Estado do Pará.

Impactos de atividades de exploração de petróleo e gás natural sobre a comunicação acústica de Mysticeti (ordem Cetacea): uma revisão

Acoustic communication is essential in mammals and has three main functions: acquisition of information about the environment, intraspecific communication and detection of predators and prey. Studies indicate that the introduction of sounds produced by anthropogenic activities such as military exercises, use of sonar and activities related to the extraction of oil and natural gas can cause interference in cetacean communication. Recently, the discovery of pre-salt tends to increase these activities. After a decade since the launch date of IBAMA`s licensing and before the imminent increase in exploration activities in Brazil, it is essential to conduct studies to monitor closely the impact of this type of activity on the marine ecosystem. Thus, this study aims to identify potential impacts that the process of oil and natural gas exploration and production might have on the communication of baleen whales. Data from literature on bioacoustics and ecology of these animals were linked with technical-scientific data regarding this type of activity. 310 documents related to the topic were analyzed. Among them only 81 documents are of academic origin, and the others mostly action plans and reports from government agencies. 80% of the documents do not have any species as a focus, and in the remaining 20%, 17% were focused on the Greenland Whale (Balaena mysticetus) and 22% on the gray whale (Eschrichtius robustus). The main impacts identified in this study were the increased frequency and amplitude of vocalization, reduction or cessation of more elaborate songs and masking problems

Diagnóstico dos resíduos gerados nas oficinas mecânicas de veículos automotivos do município de São Carlos-SP

The mechanical garages do varied types to activities related to the reparation from vehicles such as change from Motor oil, change and cleaning from car pieces, motor rectification, among others. These activities generate different kinds of waste and wastewater that when disposed in an inappropriate way can pollute the environmentand cause risks to the public health. Despite the environmental issues that involves these enterprises, they aren´t object of environmental licensing and there are any rules that regularizes their activities with the goal of these possible environmental impacts mitigation. The environmental diagnosis proposed by the present work has as goal the knowledge of the possible environmental aspects and their effects in the environment, for establishing control measures and from that to generate subsidy for environmental normatization of the sector in the municipal level. Furthermore, it should also define practices as waste production reduction, separation of them at the generator source and convenient final disposal, as well as wastewater production reduction and treatment of them before its launching in the wastewater network. The environmental diagnosis was based on a survey realized in garages from the city of São Carlos – SP, in order to define the more important characteristics of this activity that are related to the environment and public health. From the obtained information from the survey and the interpretation of the data, subsidy for the municipal environment management of the mechanical garages were generated.

O setor sucroalcooleiro no Pontal do Paranapanema: uma análise a partir do licenciamento ambiental

The development of the sugar and alcohol sector and its sugar cane cultivation has been given in an accelerated way in Pontal do Paranapanema, mainly from the last decade, and with this has taken quick changes in the dynamic socio-economic and environmental of the region, further accentuating some conflicts and dilemmas social and environmental legacy. This work was done in order that these issues are further explored, that of moving towards a greater theoretical-scientific maturity, and even has a better apparatus to support measures (corrective or preventive) that show required anti such conflicts. For this purpose, we used the environmental licensing as a means of doing this analysis, since it is one of the main instruments of control/ regulation of the State against the development of activities of the sugar and alcohol sector. We also used a little of the vast potential of information that is contained in the environmental agencies. In this case, we used six Environmental Impact Study / Environmental Impact Report (EIS /EIR), six Preliminary Environmental Reports(PER), five Characterization of Enterprise Memorials (CEM), among other documents /studies present there. Some of the information, organized and made available in this work, has even greater potential to be exploited. It was also made an essential literature survey and of the laws related to licensing and alcohol and sugar sector

Diretrizes para execução dos estudos geológico-geotécnicos e ambientais voltados à implantação de dutovias

Due to the new discoveries of oil and gas reservoirs, and also the increasing production of bio-fuels, the brazilian general pipeline system is being vertiginously extended. On the other hand, there is a lack of clear parameters that would allow a better utilization of the geological-geotechnical studies in the process of environmental licensing of pipeline systems. Therefore, this paper presents guidelines that would orientate the environmental licensing procedures to build pipeline systems, and also the geological-geotechnical studies that would support the characterization of the physical context. The method applied in this study consisted in the existing data survey and in their organization, analysis and review. In doing so, there is a well-subsidy integration of the many steps of the pipeline system implementation, the required environmental licenses and the investigation methods of the correlated physical context. As a result, it’s presented a flowchart of the guidelines, detailing the interaction between the environmental licensing, the geological-geotechnical studies and the phases of the pipeline’s project.

Showing that Early Childhood Education Works: Lessons from Italy, China, and the USA

Lessons from around the world; What does it matter about early childhood education? Why the controversy about public support for early childhood education? What process or system should be used to determine what works in early education? Can the same process be used to improve services? What is the role of government? Alternatives: 1. Consumers should determine… (What happens when private choices drive the market for early childhood services?) Observed quality of care in four Midwestern states; Parent data: “All things considered, how would you grade the quality of the care your child is receiving from his/her current caregiver?” Role of government What is a Quality Rating System? Ten states have implemented statewide systems (e.g. Colorado, Kentucky, Oklahoma, North Carolina) Findings 2. Objective science should determine… Firm findings from empirical research 3. Something else is needed: Some differences between Italian and American models. Teacher action research (and documentation) from a Reggio-inspired preschool in South Korea by Misuk Kim. Teacher Action Research at the Ruth Staples CDL. Can we now answer our opening questions? What process or system should be used to determine what is best for young children? Can the same process be used to improve the quality of services? Conclusions: The free market does not work well to determine quality in early education and care; Licensing, accreditation, and quality rating systems can help improve the market; Empirical research is useful for measuring what works; Teacher action research (reflective practice) is necessary for fostering continuous quality improvement. The tower of quality.

CRITICAL APPLICATIONS OF SW 846 US EPA METHODS TO EVALUATION OF MARINE SAMPLES QUALITY

Technical evaluation of analytical data is of extreme relevance considering it can be used for comparisons with environmental quality standards and decision-making as related to the management of disposal of dredged sediments and the evaluation of salt and brackish water quality in accordance with CONAMA 357/05 Resolution. It is, therefore, essential that the project manager discusses the environmental agency`s technical requirements with the laboratory contracted for the follow-up of the analysis underway and even with a view to possible re-analysis when anomalous data are identified. The main technical requirements are: (1) method quantitation limits (QLs) should fall below environmental standards; (2) analyses should be carried out in laboratories whose analytical scope is accredited by the National Institute of Metrology (INMETRO) or qualified or accepted by a licensing agency; (3) chain of custody should be provided in order to ensure sample traceability; (4) control charts should be provided to prove method performance; (5) certified reference material analysis or, if that is not available, matrix spike analysis, should be undertaken and (6) chromatograms should be included in the analytical report. Within this context and with a view to helping environmental managers in analytical report evaluation, this work has as objectives the discussion of the limitations of the application of SW 846 US EPA methods to marine samples, the consequences of having data based on method detection limits (MDL) and not sample quantitation limits (SQL), and present possible modifications of the principal method applied by laboratories in order to comply with environmental quality standards.

Integração de critérios técnicos, ambientais e sociais em estudos de alternativas locacionais para implantação de aterro sanitário

A Política Nacional do Meio Ambiente tem como objetivo a conciliação do desenvolvimento econômico e social com a qualidade ambiental, e dispõe de vários instrumentos que procuram contemplara capacidade de suporte do meio. Assim, a discussão sobre a localização das atividades é uma etapa importante para a avaliação da viabilidade ambiental de um determinado empreendimento, notadamente em processos de licenciamento ambiental. O trabalho apresenta uma abordagem metodológica para integração de critérios técnicos, ambientais e sociais em estudos de alternativas de localização de aterros sanitários, com especial atenção à interação entre os aspectos ambientais e os elementos fundamentais de um projeto (a saber, requisitos locacionais e concepção tecnológica), aplicado em um estudo de caso em São Carlos (SP). Como resultados principais, destacam-se o maior foco nos impactos significativos e a possibilidade de envolvimento de segmentos importantes da sociedade previamente à elaboração dos estudos ambientais.
