Planejamento ambiental da bacia hidrográfica do córrego Embirí – UGRHI Pontal do Paranapanema – São Paulo: inventário e diagnóstico

This study aimed to contribute to the environmental planning of the watershed Embirí stream - UGRHI Pontal Paranapanema (belonging to the Paranapanema Management unit) in the cities of Presidente Prudente and Regente Feijó, São Paulo. This basin is located in the area of the Santo Anastácio river source, responsible for supplying water to about 30% of the population of Presidente Prudente. The methodological procedures based on Leal (1995) and Rodriguez et al. (2004), and the steps include inventory and diagnosis of the basin. We conducted extensive literature review, cartographic and documentary on the subject area of research, field work, preparation of thematic maps and summary chart of physical units and environmental use and land cover, participatory mapping of environmental risks, quality analysis of water. Most of the basin of the stream of twine had a high environmental fragility and the main problems found were lack of riparian vegetation, erosion, siltation of water bodies, irregular disposal of debris and the dumping of sewage. The results were summarized in the diagnosis and can identify the most important environmental impacts, environmental and spatial weaknesses of the legislation, and thus draw up proposals for action to the area that is substantially degraded

Auxílio do geoprocessamento para a geração do mapa de suscetibilidade à erosão: o caso do córrego Mandu, Rio Claro/SP

The mining of sand, currently, is essential for urban growth, by providing input for the building industry. The consequences of this mining activity to environmental triggers may be severe and irreversible. Among the major impacts caused by sand mining the riparian vegetation removal is detached. The riparian vegetation is essential for balance and maintaining the local ecosystem. For all that had been shown, is possible to verify the importance of environmental studies in areas wich there are mining. This study aimed specially to assess environmental impacts triggered by a mining, located near the headwaters of the stream Mandu, situated in Ajapi, District of Rio Claro-SP. For this purpose, we used remote sensing techniques and GIS to produce thematic maps of slope, pedology, geology, land use and occupation of the soil, and riparian vegetation, using the capabilities of GIS / ArcGIS. The slope map was based on data from the Cartographic IGC 1979, scale 1:10,000. For the production of pedological and geological maps were used Semi-Detailed soil survey of the state of São Paulo, 1981 (1:100,000) and the Geological Map of Zaine (1994), scale 1:50,000, respectively. Since the maps of Use and Land Occupation and Riparian Forest were obtained by visual interpretation of the image of CBERS 2010 following the merger between the HRC and CCD images. From these mappings, and through multi-criteria analysis, map of susceptibility to erosion was made, which supported the environmental assessment of the studied area, indicating susceptible and unsuitable areas for the deployment of economic activities and urban sprawl. This study serves as a model can be replicated in other watersheds, assisting in the proper use planning and land use, aiming at the rational use of natural resources

A questão cultural no município de Álvares Machado: a importância de políticas públicas no processo de preservação urbano-ambiental

This work analyzes the importance of public policies in the process of urban-environmental preservation of the Alvares Machado city at state of Sao Paulo in Brazil, where priority was given to questions related to cultural heritage. Adopting the concept of territory as base to understand the complexities in the city, this work clarifies and contextualizes the historical heritage legislation through the Master Plan and the City Statute. The work also focuses on the contribution of the geographer toward studies related to urban-environmental planning.

Medidas de adequação dos impactos causados por uma indústria de esmagamento de soja

In the last years, environmental issues are being gradually addressed because of awareness regarding the limitation of natural resources for the maintenance of life on Earth, and the role played by the media in reporting on various issues that are related to the theme. In the industrial sector, this topic becomes ever more present in its planning. With the increase of production activities, the generation of waste causes many complications, both in industry and in the environment. For this reason laws and rules were created so that such problems are minimized, thus causing less impact on the environment. In this work was a study of the possible environmental impacts in a soybean crushing industry, situated in the city of Osvaldo Cruz, São Paulo state, detailing the sources and impacts of waste generation, and associate them relevant laws. From this, measures were proposed measures of adequacy involving compliance with commitments to environmental agencies, relevant requests of buyers and / or suppliers and improving environmental performance

Identification of quinolactin alkaloids from fungi associated to Brazilian red algae Dichotomaria marginata by LC-PDA-MS and LC-MSn

Fungi isolated from marine organisms have been shown to produce several interesting secondary metabolites with important biological activities. Such chemical diversity may be associated to environmental stress conditions and may represent an important source of NCE for bioprospection. Quinolactins belong to a rare fungi-alkaloid class with a unique N-methyl-quinolone moiety fused to a lactam ring and present several bioactivities1. Fungi strain Dm1 was isolated from red alga Dichotomaria marginata, collected from Brazil SE coast, and was grown in sterile rice solid media at 26oC 2, which was then extracted with MeOH. The MeCN fr. from the MeOH extract was chromatographed over Sephadex LH-20 and fr. 4 afforded quinolactin (QL) alkaloids B1, B2 and A, whereas fr. 5 afforded quinolactin D1 after purification by HPLC-DAD. Structural determination of pure compounds was based on HRMS, UV, and NMR spectral analyses, in addition to comparison with literature data and Antimarin® databank. UV data indicated the presence of similar chromophores with λmax at ca. 247 and 320nm. HRMS and tandem MS analyses using both negative and positive ion modes for the isolated compounds indicated their molecular formula and structural features, as for QL B1: C15H16O2N2 [M+H 257], which showed one fragment at m/z 214 [-CHNO]; QL B2: C15H16O3N2 [M+H 273], with product ions at m/z 230 [-CHNO.] and m/z 186 [-C4H9NO.]; for QL A: C16H18N2O2 [M+H 271], which presented one ion at m/z 214, due to loss of fragment (-C4H9) from the molecular ion; and for QL D1: C16H18N2O3 [M+H 287], with product ions at m/z 186 [-CHNO] and m/z 230 [-C4H9]. Such data suggested fragmentation proposals, e.g. for Quinolactin B1 (Fig. 1), which confirmed the structures of the isolated quinolactins, and may represent an important contribution for the sustainable exploration of marine biodiversity.
