ATLAS INTERATIVO DO PONTAL DO PARANAPANEMA

The Pontal do Paranapanema area is located in the western part of São Paulo State, in the southeast of Brazil. The main objective of this Atlas is to bring together, through topographical and thematic maps, all the geographical information about the Pontal do Paranapanema, in order to serve as a basis for studies and planning of the government (at municipal and state level) as well as to the private sector. The Atlas also aims at becoming an information product about socio-economic conditions of this area directed to academic studies of the regional community. Evaluation of the Interactive Atlas was done by educators and the result indicates that this information product promotes the knowledge about the Pontal do Paranapanema and it is a contribution to Environmental Education. This research project has had the support given by FAPESP, UNESP and FUNDACTE.

Gerenciamento de áreas contaminadas por postos de combustível por meio de geoprocessamento em Presidente Prudente (SP)

With the development and rise of cities, many contaminated areas were occupied for various purposes, a fact that can bring risks to the population. This study aims to survey and map all contaminated areas confirmed by CETESB caused by gas stations in the city of Presidente Prudente, located at the western end of São Paulo state. With this information and the appropriate treatments within a computing environment, it is possible to represent spatially these data and create a GIS which can be used by the local authorities responsible for licensing and environmental control. We found fourteen areas contaminated in various parts of the city and the main cause of contamination was inadequate storage of fuels. There are some points with concentration of contaminated areas close together, mainly in the eastern quadrant of the study area (covering the central region of the city), which is a potential risk area. The most frequent types of contaminants are aromatic solvents and polycyclic aromatic hydrocarbon (PAH). They cause irritation to the skin, eyes, nose and throat. There are further toxic components which affect humans and the environment, contaminating both subsurface water and groundwater. In this study we indicate procedures which should be followed by the local authorities to avoid or minimize the consequences of these problems which affect strongly the local population and the environment.Pages: 1136-114
