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

Radônio como indicador de contaminação de solos por hidrocarbonetos

Previous studies show that in areas contaminated by fuel spill (NAPL- non-aqueous phase liquids), from operational activities, transport and storage, it was possible to observe a significant decrease of ²²²Rn (radon) gas concentration in the soil, even a non-uniform distribution of this gas in top soil, even with a geological situation was practically homogeneous. These anomalies may be associated with the preference partitioning of radon in NAPLs. This work consists of applying ²²²Rn as an indicator for locating subsurface contamination by NAPLs in an area of the city of Rio Claro (SP) where, according to the “Survey of Contaminated and Rehabilitated Areas in the State of São Paulo (Environmental Sanitation and Technology Company - CETESB), there was, in the year 2007, groundwater contamination from leaks of liquid fuels. The challenges of this research are: Promulgate the use of a new tool with greater efficiency in obtaining results, in addition to generate less impact in half and have less expenditure; disseminate scientific culture promoting greater integration of C&T (culture & technology) between universities and businesses. The emanometric technique to estimate the location, number and interfacial area of NAPL in saturated and non-saturated zone, has the advantage of locating and determining plumes of free phase even when the amount of VOC's (Volatile Organic Compounds) that reaches the surface is low or non-existent. In addition, the measurement techniques ²²²Rn are quite developed. The results obtained show that, similar to the other studies, the 222Rn soil gas presents an anomalous behavior in the area bounded by NAPL plume, being possible to note a significant deficit in the concentration of the gas in spots where the saturation by NAPLs is still critical. Therefore it is concluded that this tool is really promising, but we must be careful to evaluate the initial conditions of the area, as well as the type of...

A curva de Kuznets ambiental e os municípios paulistas: análise de áreas contaminadas

Este trabalho tem o objetivo tratar empiricamente a hipótese da Curva de Kuznets Ambiental aplicada aos municípios do Estado de São Paulo, relacionando dados de áreas contaminadas e de renda per capita referentes ao ano de 2009. O instrumental econométrico utilizado foi o de mínimos quadrados ordinários, tendo como modelo uma função cúbica da renda per capita como variável explicativa, além da inclusão de uma variável de crescimento médio da renda, e o número de áreas contaminadas como variável a ser explicada. A estimação teve como resultado uma curva em formato de “N”, indicando uma queda da degradação ambiental seguida de uma nova elevação com o crescimento da renda

Investigação geoambiental de áreas contaminadas com elaboração do modelo conceitual em campo utilizando ferramentas de alta resolução (HRSC)

The Brazilian geo-environmental site characterizations usually do not provide a suitable Conceptual Site Model (CSM). Site assessments are mostly inappropriate and there is a lack of knowledge about the subsurface environment, generated by inconsistent data that will guide risk analyses and remediation projects full of uncertainties, causing delay on closing cases, inefficient remediation and higher global projects costs. The step of data collection must have high priority to develop a suitable CSM,, and it demands more effective high resolution site characterization (HRSC) tools than the traditional ones and, preferably, the decision-making have to be done in the field. This paper presents and discusses two geo-environmental site characterization results, in which the decision-making was done in the field based on high resolution site characterization (HRSC) used together with the traditional ones. These site investigations provided a significant time saving, allowed the detection of subsoil heterogeneities, a proper understanding of the subsurface environmental, and have generated a solid CSM in real-time. These CSM can subsidize remediation projects based on a more reliable data than those that would be obtained in traditional site investigations, concerned just in following the rules established by the environmental agencies.

Amostragem de poluentes gasosos e particulados emitidos pela queima de biomassa vegetal

The use of biomass as an energy source has been increasing in Brazil, with emphasis on the use of wood biomass, such as bark, wood chips and sawdust, that after receiving the appropriate treatment can be used in burners for power generation. However, from this burning are emitted fine particles known as particulate matter and a wide range of toxic organic and inorganic components in the form of gases that contribute greatly to air pollution and global warming, affecting human health, the environment and climate. The objective of this project was the quantification of gaseous and particulate, using and evaluating the equipment DR4000 ( Dataram 4 ) sampling of particulates smaller than 2.5μm and EUROTRON ( Ecoline 4000 ) when sampling gaseous pollutants, emitted from the burning of biomass in real time in the firing burner to a chimney attached biomass . We note that there are no specific rules that establish emission limits for particulate matter with diameter less than 2.5μm that are most harmful to human health and the highest concentrations reached about 800000μg/m3, for smaller diameters. It is noticeable the need for sampling of pollutants especially in industries that use biomass to fuel that could be implanted emission control equipment

Contaminação das águas subterrâneas por resíduos de postos de combustíveis: uma abordagem no município de Rio Claro

The contamination of underground waters is a subject of great importance, since a lot of people use this kind of source for public supply. This paperwork manages with how gas stations can contaminate these waters and what are some remediation techniques, used nowadays to solve this problem. The contamination caused by the gas stations can have its origin in the underground storage tanks when they suffer corrosion and show leaking problems. It’s a topic of great relevance, because the hydrocarbons derivated from petroleum present in the fuels can stay for a long time in the environment. Besides that, an analyses of the risk of contamination by gas stations in the city of Rio Claro was made based on three parameters: density of the gas stations, depth of the underground water and hydraulic conductivity. To achieve such goal, maps were elaborated considering those parameters individually and considering the three of them together. Analyzing those maps, it was concluded see that the spots that represent the biggest risks of contamination in Rio Claro are located southeast and center-west.

Proposta de intervenção e gerenciamento das áreas potencialmente contaminadas: estudo dos brownfields no distrito Belém em São Paulo

In the district of Belém, at São Paulo’s city, the economic transformations have ended up destabilizing the economy industrial leaving marks that can be found today. Idle sheds, abandoned or undefined uses structures are found throughout the neighborhood, creating a scene of decay and abandonment. Despite the problems caused by brownfields, they may be seen as an area of possibilities. The reuse of these areas allows the reutilization of abandoned space in locations where the infrastructure is already available, stopping the expansion of urban spot in places not yet degraded. In the case of disabled older industries, there is a great possibility of site’s contamination that may also pose risks to people and unforeseen during refuncionalization. Therefore, the proper management of these sites is needed before any intervention in the area, where stages of study and research must be conducted in order to prove their actual situation. The survey and study of these areas in the district of Belém in São Paulo provides an overview about the brownfields in Brazil at the same time that contributes to the development of intervention plans and proposes a scenery for the refuncionalization of these sites in the neighborhood.
