Exposição ambiental ao chumbo: um problema de áreas contaminadas próximas a fábricas de baterias

The concentration of metal pollutants such as lead (Pb), has grown and developed in populated areas due to pollution and other human activities. Consequently, the potential for achieve this element food chain has also increased. Lead is very toxic to humans, especially to children, and exposure to lead can cause adverse health effects mainly on human nervous system, bone marrow and kidneys, interfering with chromosomal or genetic processes. This paper presents an overview of the main aspects related to environmental contamination by lead from battery plants. The assessment of an area contaminated by lead in Bauru-SP next a battery factory was reported in this work as well as the entire history of monitoring, classification and application of processes applied by CETESB since 2002. Analyzing the issue in its economic aspects, we found that the degradation of the environment is directly related to the development model adopted by the capitalist system, which is based on the law of supply and demand for products and services. The data presented indicate that Brazil still needs a broader policy where government agencies, industries and population through awareness can be united for the same purpose: to preserve life

Proposta de sistemática operacional para implantação de sistemas de gestão ambiental em empreendimentos industriais

The implantation of environmental management systens (SGA) in companies is the first step to the company conquers the environmental certification and consequently the benefits of a sustainable production of products, services and activities can bring. However, in the way as they are proposals in bibliographies the implantation of the SGAs, does not identify the definition of the operational stages of implementation of the same ones, generating doubts on the real environmental and administrative performance that they can come to generate for the organization. In this direction, the present research brings a proposal of operational systematics for implantation of SGA in companies, detailing each stage of implantation, considering its particularitities. For in such a way, a revision of norm NBR ISO 14001:2004 was made, looking for to identify to the interpretation imperfections gifts in the normative system. Moreover, other methods of SGA implantation had been searched gifts in the bibliography, searching proposals that detailed the operational aspects of the implantation of the system. In the same way, the accomplishment of a period of training supervised in the first semester of 2007 made possible the practical experience of the functioning of a system of environmental management, beyond the contact with professionals of the area and the acquisition of documents that had helped in the development of the research. The result was the attainment of a detailed procedure more, defining the operational systematic of SGA implantation, beyond the generation of a flowchart, describing as to develop each stage. This detailing certainly will facilitate the implantation of a SGA in companies interested in improving its environmental performance.

Análise ambiental em um canteiro de obras

The building sector can cause the environmental degradation, by the natural resources consumption, machinery use and natural landscape modifying. The environmental management system (EMS) improves the environmental quality and makes the companies more competitive. So, this work developed an environmental management system in a building site focused on the solid waste and in the development of mitigation proposals for the most significant environmental impacts. To develop this work it was necessary to follow the building site activities; evaluate the solid waste management; identify the law requirements; identify the environmental aspects and impacts; evaluate the environmental impacts; and propose alternatives for mitigating the adverse environmental critical impacts. The main proposals are the reduction of the waste generation in the place that it’s generated; the reuse and correct final disposal of that wastes; the treatment and reuse of the effluent; and the supervising in the trucks and machineries avoiding the oil spilling and the air pollution

Comportamento forrageiro de abelhas visitantes de Solanun lycocarpum (Solanaceae) St. Hill e aspectos da biologia floral

A polinização é um serviço indireto prestado pelos ecossistemas, de valor ambiental e econômico para a sociedade humana. Em função dessa importância, a conservação de espécies de abelhas nativas é fundamental e o conhecimento de aspectos da biologia e ecologia dessas espécies é a base para a proposição de planos de manejo e conservação. Neste trabalho, foram feitas observações focais, avaliando os padrões de atividades diárias e sazonais, com ênfase no comportamento de coletas de recursos de abelhas nativas em flores de Solanum lycocarpum, uma espécie em que é característica a síndrome de polinização vibrátil. Os visitantes observados foram dez espécies de abelhas: Apis mellifera L., Oxaea flavescens K.; Centris sp1, Centris sp2, Exomalopsis sp.., Xylocopa suspecta M., Xylocopa frontalis K., Bombus morio S., Bombus atratus F., Trigona sp., além de espécies de abelhas da família Halictidae. As abelhas maiores, como Xylocopa, Oxaea, Centris e Bombus são certamente os polinizadores mais eficientes de Solanum lycocarpum. Isso se deve ao comportamento dessas abelhas nas flores, particularmente em relação à posição da abelha em relação ao cone de anteras quando forrageia e à seqüência de movimentos que cada uma desenvolve nas flores.

Implementação de um sistema de informação para cartas de sensibilidade ambiental a derrames de óleo e elaboração de mapas de vulnerabilidade ambiental a derrames de óleo para o município de Caraguatatuba-SP

Fossil fuels are the main energy sources of the modern industrial age. Very sophisticated processes have been developed to extract these resources, due to increased demand on a global scale, as the extraction of oil. However, the complexity of these processes can cause accidents such as the release of oil to seas and oceans. In this context, this study proposes to carry out the implementation of a system of information to charts of environmental sensitivity to oil and prepare maps of vulnerability to oil for the city of Caraguatatuba-SP. The implementation of the database with geographical information of coastal environments was appropriate to be provided by the Internet, allowing wide access of data. The maps of vulnerability are important tool developed for the Individual Emergency Plans, because they were developed in operational scale, appropriate to actions to combat oil.

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...

O risco ambiental representado por campos eletromagnéticos em Presidente Prudente (SP)

Currently the mobile services represent an essential tool in daily life of the population. However, while offering greater convenience to its users, there is growing concern about the harmful effects to human health, derived from daily exposure of the public to electromagnetic fields from radio base stations (RBS), since even today, there is no study proving that longterm exposure to low-level fields are not harmful to health. In Presidente Prudente has not been a study reporting values of measurements of electromagnetic fields from base stations installed in the city. Based on these data, this study aimed to assess the levels of electromagnetic exposure in the city of Presidente Prudente regarding recommended by international bodies, as well as propose measures that can reduce public exposure to electromagnetic fields. For measuring values of electromagnetic fields, we used appliance Electromagnetic Field Meter Portable Digital - DRE-050, the Instrutherm, following the methodology suggested and adapted from the Adilza Condessa Dode’study. In total, 49 points were mapped corresponding to the areas at risk of exposure to electromagnetic fields generated by the substations of power grid, transmission towers and telecommunication towers located in the city of Presidente Prudente (SP)

Zoneamento acústico urbano e mapeamento de níveis sonoros na zona central de Rio Claro (SP): diretrizes para o gerenciamento do ruído integrado ao planejamento ambiental urbano

Considering the growing degradation of the urban environmental quality resulting from the progressive sound pollution increase, as well as the consequent harmful effects about the human health, the present study had its central objective the argument and management tools implementation of the urban noise that can be integrated to the environmental planning in the city of Rio Claro (SP). Therefore, normative and bibliographical revisions were developed, that made feasible the directives of control argument and prevention of the urban noise, as well as the technical procedures of sound levels and evaluation’s definition and especially about the criteria applicable for the elaboration of an urban acoustic zoning methodology. Among the main results obtained detach: (1) the applicable legislation to the management of urban noise’s synthesis and argument; (2) the methodology of urban acoustic zoning development and (3) its implementation to determined areas of Rio Claro (SP) with the (4) respective cartography representation; (5) the mapping of sound levels in the central zone of Rio Claro (SP), (6) the obtaining and analysis of noise describers (LAeq, Lmáx, L10, L50, L90, Lmin and TNI) and the subsequent (7) acoustic maps elaboration for the main describers.

Experimentação e educação ambiental: contribuições metodológicas

During the last centuries, the human being have been considered the center of the universe. The man believed that nature was at his disposal. Appropriated their processes, their cycles changed, redefined their spaces. Today, when faced with an environmental crisis which threatens the planet life, including the human life, the Science Education can contribute to a reconstruction of man-nature relationship in other terms. The transformation of teaching practices in the school environment, to be reflective, it is still a process that challenges the vast majority of teachers. As has been indicated by Guerra (2004), among others, the traditional teaching of content delivery is still very strong and certainly more deeply embedded in ideas and activities of the teachers who focus on environmental education. With it, a theory and pedagogical discourses in critical-reflexive actions is still a major obstacle. Therefore, new proposals for education and continuing education activities need to be formulated and presented based on the characteristics and needs breathing. Therefore propose changes in the way of teaching, where there is more room for a theory and praxis alone or with a only scientific truth. The scenery of society requires that knowledge is constructed to interconnect all disciplines, joining theory and practice so we can understand the whole and their relations in an integrated manner. It was proposed here a way to build a school and applying theoretical and practical activities involving experimental and seeking to meet the principles of Environmental Education for the training of citizens aware and critical. At the same time cares to use textbooks very rich in its pedagogical character that are present in schools and often are, forgotten and unused by teachers. From this way, I chose to Experimentoteca, ...(Complete abstract click electronic access below)

Diagnóstico ambiental das áreas de expansão urbana do município de Jaguariúna - SP

The spatial chaotic urban growth is an increasing and common problem in Brazilian cities, especially in the State of São Paulo. In order to assist the territorial expansion planning, the present study aimed to conduct the environmental diagnosis of urban expansion areas in the City of Jaguariúna – SP, bounded by the Municipal Plan. From the preparation and analysis of thematic maps, literature review and field analysis, data were collected for use and occupation, geology, geomorphology, pedology, vegetation, water resources and features surrounding the five urban sprawl existing areas. It was noted, in general, that these areas are suitable for urban occupation, since they show flat geomorphology characteristics, with flattened, medium to large hills, slightly undulated, with low slope, and soils that do not present risks to the deployment of buildings, once properly managed. It was also observed a few water bodies crossing these areas and a few areas with native vegetation beyond permanent protection areas along the rivers. By the analysis of these areas and their surroundings, it was possible to determine on which area the urbanization process can occur more quickly. Thus, the study allows the City of Jaguariúna to perform a more effective occupation planning in these areas, always aiming the sustainable development and, consequently, the improvement in population’s quality of life, as well as the maintenance of environmental quality.

Organização e implementação de um banco de dados para a sensibilidade ambiental ao óleo e avaliaçao de ações adequadas de resposta a derramamentos - São Sebastião (SP)

The need to know and to preserve the coastal ecosystems is justified by the whole importance that those ecosystems have for our society. Then, it is big the concern in guaranteeing that those places stay free from contaminations. Among the several types of potentials pollutants that can affect the coastal systems, the petroleum-derived are the ones that cause the worst impacts, given the frequency of these accidents. Rapid actions are necessary in order to minimize the oil negative effects . This answer is faster when the most sensitive areas are known and when it presents characteristics of larger importance, as for instance, the presence of sea harvesting or the habitat of an endemic specie. Besides, it is necessary to know which cleanup methods are recommended and which are not recommended for the reached areas, so, the corrected emergency plans for each coastal environment can be applied. It is in this context that this project was developed, implementing a geographical database for the different coastal environment of São Sebastião municipality, SP, and also the data about the best cleanup techniques for each segment of the coast. This database was made available by the internet, enabling the access for several types of users.

Avaliação da influência do enriquecimento ambiental nas variáveis comportamentais de saguis-de-cara-branca (Callithrix geoffroyi) em cativeiro

Six species of the genus Callithrix can be found across the Atlantic Forest extension, being the Callithrix geoffroyi, Geoffroy`s marmoset, the least studied species. The objective of this study is to investigate the behavioral aspects of the species in captivity, and how the environmental enrichment techniques influence those behaviors. To this end, we have studied three specimens of C. geoffroyi, in captivity at Municipal Zoo of Piracicaba, São Paulo. The enclosure includes a 37m2 with under masonry, concrete platforms with external deep, trunks, a floor of grass and soil, e grid in their other three sides. The sampling method was focal per time interval, with records every 30 seconds in sessions of 30 minutes, totaling 30 hours for each animal, which were distributed in a baseline phase, an environmental enrichment phase and post-enrichment phase (n = 3660 records in each phase). The twelve enrichment techniques were applied: the physical environment (branches for perches and hoses fabrics for bedding and vanishing points), cognitive (radio, mirror, puzzle food) and food (insects, flowers and eggs hidden, wrapped). Initially, to determine the period of greatest activity of marmosets, we investigated the pattern of activity for three days (9:00 am to 17:00 pm) consecutively at intervals of 15 minutes, recording the number of active and inactive individuals. The 495 records signaled greater activity in the morning, then selected period for the completion of this work. The ethogram comprised 16 behaviors. The inactivity was the predominant phase behavior baseline and post-enrichment with a significant decrease (h=8,62, p <0.01) in the enrichment phase, and a significant increase in the post enrichment (h=18,15, p <0.001). The same was seen for the use of substrate (grid and ground vs. Trunk and concrete, h=5,09, p <0.001 and h=3,98, p <0.05)... (Complete abstract click electronic access below)

O Sistema de Gestão Ambiental e sua contribuição socioambiental para a biblioteca central da UNESP, Campus Rio Claro/SP

The minimization and mitigation of environmental impacts caused by the activities of organizations is increasingly becoming a key concern due to factors such as market demand, including suppliers and consumer markets, quality standards and even marketing strategies. The implementation of an EMS - Environmental Management System - allows the organization to achieve the level of environmental performance for its determined and promotes continuous improvement over time. This system consists of a schedule of activities, so as to eliminate or minimize impacts to the environment through preventive actions. It also provides a structured approach to set and achieve goals and objectives, and to establish procedures, work instructions and control, ensuring that the implementation of the policy can become reality. The objective of this work consists in planning a system using environmental management based on the ISO 14001 - standard internationally more widespread and accepted in the requirements to establish and operate an EMS - the Central Library, UNESP, Rio Claro / SP to stimulate the quest for continuous improvement and sustainability in the educational institution. For making the diagnosis of this planning was used the PDCA methodology, suggested by the standard, as well as all requirements for compliance. The results show that the benefits that the organization will receive involve reducing expenses and cost of energy and water, and improve the organization's reputation before the whole university and other educational institutions, reaching about three thousand people on university

A antropogeomorfologia na bacia do Córrego do Cavalheiro - Analândia/SP: uma avaliação da dinâmica do uso da terra e sua adequabilidade a legislação ambiental e a capacidade de uso

The assessment of land use dynamic can be an instrument for analysis in anthropogeomorphology, which would allow one to verify the human geomorphological actions and its various implications in changing the original morphology for the creation of a human morphology. This study aimed to consider the land use dynamics and its interference in the morphology of Cavalheiro Stream Basin. From this assessment, to understand the implications of land use in the creation of a human morphology, as well as to analyze if the current use is in accordance with the legal restrictions placed by ongoing environmental legislation and with the ability to land use. The chosen of this studied area was due to assumptions raised by Pinton (2007) for changes in the dynamic of rainwater erosion of this area caused by human actions, specially the cultivation of sugar cane in morphologies that are unfit for it. The search took as methodological support the principles that concern the General Systems Theory, trying to see the watershed as an open system. The geomorphological data, of land use and of legal restrictions to the use and occupation of land, were collected from different cartographic techniques. Besides, it was developed a sketch map of land use capacity by adapting the technique proposed by Lepsch (1983). This way, the data obtained in this survey are considered capable to provide subsidies for the identification of changes in original morphology of the Cavalheiro Stream Basin and the genesis of a human morphology, as well as conflicts and adjustments of current land use in environmental system and on the legal restrictions outlined in the ongoing environmental legislation, contributing to a proper environmental planning with the characteristics of the physical environmental system of this basin

Prevalência das enteroparasitoses em escolares após Programa de Saneamento Ambiental (Bahia Azul) realizado em Salvador, BA

Introduction: The intestinal parasites continue to represent a significant public health problem, due to the large number of infected people and the various organic changes that can cause. The intestinal parasites become more prevalent in villages with high population density absence or inadequacy of sanitation and adequate, and personal hygiene practices and inadequate housing. Objective: To determine the prevalence of intestinal parasites Ascaris lumbricoides, Trichuris trichiura and Giardia duodenalis in children of school age (7-14 years) living in the city of Salvador, Bahia, which were part of the Environmental Sanitation Program (Bahia Azul) covering eight different sewage basins in the years 1997/1998 and 2003/2004. Methods: Data were collected pre-coded questionnaire administered to the parents of students, collecting information socioeconomic, environmental and housing conditions. Stool samples were analyzed for each school in the Laboratory of Parasitology of the ISC, UFBA. The database was built and analyzed by Epi Info program (version 3.5.1/2008) were built where overall prevalence rate and Basin depletion of parasites. We compared the overall prevalence rates (at least one parasite) before and after the intervention health, as well as species of parasite. Results: The overall prevalence before the intervention was 56,2% (N = 729) and 42,5% after the intervention (N = 890), down -24,5%. The prevalence observed for each species A. lumbricoides, T. trichiura and G. duodenalis before intervention was respectively 31,4%, 35,8% and 9,9% respectively after the intervention and 24,4%, 28,8% and 6,0%. In relation to variations in prevalence were found to decrease A. lumbricoides, T. Trichiura and G. duodenalis respectively -22,4%, -19,7% and -39,7%. When the results were compared by Basin exhaustion, it was observed that the greatest variation with reduction occurred among students Basin M. Camurujipe to at least one parasite (-51,4%), ...
