Propostas de Adequação Ambiental para a Cidade da Criança de Presidente Prudente - SP

The environmental issue has been considered of fundamental importance for the well being of the present and future generations and is inserted into the commitment of political parties at federal, state and municipal government programs, into the interests of popular organizations and business planning. The Parque Ecológico Cidade da Criança is one of the most sought after places for visitation at Presidente Prudente – SP. Located outside the Raposo Tavares Highway, next to the exhibition grounds and beside the agricultural school, has more than 30 acres of area with an infrastructure designed for recreation and leisure activities for all ages and has received new investment of the public power. Given the importance of the ecological aspects, the objective of this work is to perform an environmental diagnosis in order to be able to submit proposals for solving the problems encountered and improve the use of the environmental resources. Therefore, the study was divided into three foci: sewage disposal, erosion process and control of the stormwater drainage system. It was checked the discharge of sewage from the restaurant on exposed soil, erosion processes that develop at the camel and llama cages ground and erosion processes resulting from the convergence of the stormwater in the highest region of the park. Based on these studies, proposals of solution were made for each case, having considered the effectiveness of the project

Análise da viabilidade econômica na implantação de inversores frequência em sistemas de bombeamento

The present work aims to conduct a study of the economic feasibility of the implementation of variable frequency inverters in pump systems with variable flow rates. The concern with the reduction of energy expenditure in industries raised in 2001 due to the energy crisis that hit Brazil at that time, forcing industries to reduce their electric costs under penalty of fines if this were not done (MOREIRA, 2008). Frequency inverter is an electronic device that allow greater control in the operation of pumping systems and also a reduction in electrical consumption, being a viable solution to achieve a reduction in energy consumption. For the development of this work, approaching important topics in pumping systems was necessary in order to make a correct choice of hydraulic pumping and also other components responsible for the operation of the system , such as electric motors and frequency inverters. In the case study, a theoretical analysis of the behavior of electrical consumption in systems with variable flow rates was performed, comparing when the system is operated via frequency inverters and when the system is operated without such a device. As expected, the result of the implantation of the device was quite satisfactory, and the primary goal of reducing energy expenditure was achieved. Also important to highlight the environmental issue of this work, as all forms of energy production affects nature in some way, achieving a reduction in consumption also contributes indirectly in environmental conservation

Estimativa das emissões de monóxido de carbono por veículos automotivos na cidade de Campinas/SP utilizando o modelo CAL3QHCR

Air pollution is an environmental issue worldwide and frequently cause negative effects on population health and ecosystems on cities. The relationship between climate and atmospheric pollution can be used as a surrogate to the intensity of air pollution. The present and quantity of some gases can be used as indicators to air quality: particulate matter (PM), sulfur dioxide (SO2), carbon monoxide (CO), ozone (O3), and nitrogen dioxide (NO2). Among those gases, CO has its major source within the cities, where automobiles are the main emitter. But measure pollutant concentration are challenging, sometimes because the lack of good equipments due to high costs and of the large variability of models that varies in precision, way of measure and distribution of sellers. Modeling are useful when there are an intend to evaluate air pollution, its sources and evaluate scenarios. This work aims to use CAL3QHCR model developed by the U.S Environmental Protection Agency (EPA) to generate predictive surfaces of CO concentration distribution on a site within Campinas city, located in São Paulo state, Brazil. CAL3QHCR model use data urban automobile circulation to generate spatial results for CO distribution. We observed that the pollution concentration was lower on our modeling than the concentrations measured by Companhia Ambiental do Estado de São Paulo (CETESB), the main environmental company on the São Paulo state. Also the correlation between average estimates of our model and the measure by CETESB was weak, indicating that the model used on this study need to be or better parameterized, or the scale we measured of CO emissions need to be rescaled. Although the model failed to correlate to CETESB data, maybe one that explore the estimated emissions distributed within the sites to understand spatial distributions of CO on the regions. Also, the generated information can also be used to other studies, and come to be useful to explain heat island

Pesquisa em Educação Ambiental: compromisso com a vida

Different environmental disasters registered around the world and their consequences to nature and to the biodiversity, including the human beings, lead us to deal with nature’s mysteries and with our limits In controlling technological apparatus that make us proud enough to think that we can control nature’s processes. These kinds of experiences, considered as a real “being-event”, make us experiment processes of disillusion related to the possibilities of science and technology. Considering this frame and the historical human experiences, one fundamental question is related to our position, our professional and ethical commitments and our responsibilities facing this reality. How can we deal with these facts that are continuously announcing the limits of nature, of science, technologies and our self-limits? As researchers involved with environmental education, it seems plausible for us to ask about the ethical commitments related to our “acts” of investigation. So, considering different and stimulating possibilities opened by intellectual and philosophers who are adding significant contributions to these debates, my proposal for this essay is to invite environmental education researchers to carry on a dialog involving these questions with some perspectives proposed specially by Bakhtin (1895 – 1975) and some other authors affiliated or not to his approach. This seems to be an opportunity which allows us to realize that our commitments as environmental education researchers would be identified with our commitments with life

Gestão ambiental: um novo desafio para os profissionais de recursos humanos?

Current research analyzes the importance of human resources managers in organizational sustainability through the ack-nowledgement of the external variables and innovatory practices, such as environment management. In fact, the latter is a challenge for organizations and consequently for the human resources’ area. Investigation comprised a revision of the literature: theoretical and empirical articles that deal with the role of human resources’ mana-gement and on the environmental issue which is daily in the news. The essay is divided into three parts: the first section emphasizes the role of human resources’ managers; empirical evidences of the activities of HR managers in international contexts are dealt with in the second part; the third section deals with the environmental ma-nagement issue as a new challenge for HR managers. HR managers should acknowledge and incorporate in human resources practice the environmental dimension from the stages of recruitment, selec-tion and training. If people with attitudes and competences in the environment are rewarded, they will contribute towards an effective environmental management and, consequently, improvements in organizational results will materialize.

Radiocarbon Dating, Chronologic Framework, and Changes in Accumulation Rates of Holocene Estuarine Sediments from Chesapeake Bay

Rapidly accumulating Holocene sediments in estuaries commonly are difficult to sample and date. In Chesapeake Bay, we obtained sediment cores as much as 20min length and used numerous radiocarbon ages measured by accelerator mass spectrometry methods to provide the first detailed chronologies of Holocene sediment accumulation in the bay. Carbon in these sediments is a complex mixture of materials from a variety of sources. Analyses of different components of the sediments show that total organic carbon ages are largely unreliable, because much of the carbon (including coal) has been transported to the bay from upstream sources and is older than sediments in which it was deposited. Mollusk shells (clams, oysters) and foraminifera appear to give reliable results, although reworking and burrowing are potential problems. Analyses of museum specimens collected alive before atmospheric nuclear testing suggest that the standard reservoir correction for marine samples is appropriate for middle to lower Chesapeake Bay. The biogenic carbonate radiocarbon ages are compatible with 210Pb and 137Cs data and pollen stratigraphy from the same sites. Post-settlement changes in sediment transport and accumulation is an important environmental issue in many estuaries, including the Chesapeake. Our data show that large variations in sediment mass accumulation rates occur among sites. At shallow water sites, local factors seem to control changes in accumulation rates with time. Our two relatively deep-water sites in the axial channel of the bay have different long-term average accumulation rates, but the history of sediment accumulation at these sites appears to reflect overall conditions in the bay. Mass accumulation rates at the two deep-water sites rapidly increased by about fourfold coincident with widespread land clearance for agriculture in the Chesapeake watershed.

Magnetic measurements performed on sediments from the Bay of Seine seafloor (France) from 2011 to 2013

Impact and monitoring of dredge spoils are an important environmental issue. This investigation aims to map two dredge-spoil dispersals in the Bay of Seine by using an innovative application of well-established environmental magnetic proxies. Low-field magnetic susceptibility measurements were performed on discrete samples from dredge sediments and from the Bay of Seine seafloor before & after dumping. The fingerprinting of the dispersion of dredge-dumped sediments is efficient due to the higher susceptibility of the dredge sediments with respect to the background. Besides, terrestrial input is also monitored in our susceptibility maps. Dilution of the susceptibility signal allows an estimation of the resilience of the sedimentary environment on a six-month survey. This susceptibility signal is controlled by the ferromagnetic fraction of the sediment. A constant magnetic mineralogy carried by magnetite is observed in the study area, thus a qualitative parameter for magnetic grain size was selected that shows an in-progress resilience pattern over the survey.

Reciclagem de resíduos eletroeletrônicos: um estudo cinético da lixiviação ácida de ferro de placas de circuito impresso de microcomputadores.

O aumento no consumo mundial de novos aparelhos eletroeletrônicos aliado à redução no tempo de vida útil destes equipamentos tem como principal consequência ao meio ambiente a geração de resíduos. No Brasil, com a instituição da Política Nacional de Resíduos Sólidos, criou-se a obrigatoriedade legal da responsabilidade dos fabricantes pela logística reversa dos equipamentos eletroeletrônicos, incentivando pesquisas para o desenvolvimento dos métodos de reciclagem e tratamento dos materiais descartados. O processo de lixiviação foi avaliado como alternativa à etapa de separação magnética presente nas atuais rotas hidrometalúrgicas para recuperação de metais valiosos de placas de circuito impresso. Para avaliar a composição das placas, foi realizado ensaio de dissolução em água régia. As amostras foram moídas e submetidas a ensaios de lixiviação com ácido sulfúrico nas concentrações de 1 e 2mol/L, às temperaturas de 75ºC, 85ºC e 95ºC, durante 24 horas. Com ácido sulfúrico 2mol/L a 95ºC, o tempo necessário para se obter 100% de extração do ferro foi de 2 horas. Nestas condições, não foi detectada a presença de cobre dissolvido. A cinética da reação é controlada por reação química e obedece a equação .=1(1)3. A energia de ativação aparente do processo equivale a 90kJ/mol.
