Nativa fm sp telefone1/7/2024 In the present study, neutron activation analysis method was applied to determine elements accumulated in Canoparmelia texana lichenized fungi. This method offers advantages such as reduced costs, efficient monitoring of large geographic areas and accumulated pollutants over a large period in which low concentrations of chemicals elements in the environment can be evaluated. Biomonitoring is a method to evaluate the response of live organisms to pollution. (author)Ītmospheric pollution biomonitoring of the Sao Paulo metropolitan region using epiphytic lichensĭue to the increasing problems of atmospheric pollution in the Sao Paulo metropolitan region that affect the environment and human health the application of biomonitoring methodologies using cosmopolite organisms has now become relevant. The petrogenetic model presented is based in the national and international bibliography. The objective of this thesis is the petrographic, mineralogic, petrochemical and isotopic characterization of the basic and ultrabasic dykes that occur between the Sao Sebastiao and Ubatuba cities (State of Sao Paulo), also including some occurrences from the Sao Sebastiao, Mar Virado and Anchieta islands and from the Bairro Alto region (Folha de Natividade da Serra). The thickness of the basic to intermediate dykes vary widely, from a few centimeters to several metres, while the lamprophyres are a few tens of centimeters thick. The main rock types range from basic to intermediate, but also a conspicuous variety of alkaline lamprophyres occur side by side with the main group. The coastline between Sao Sebastiao and Ubatuba cities and the shores of Sao Sebastiao, Anchieta and Mar Virado islands ( Sao Paulo State, Brazil) are crosscut by several small swarms and isolated dykes trending N55E. The basic and ultrabasic dikes from the coast region between the Sao Sebastiao and Ubatuba cities, Sao Paulo State, SP, Brazil The goals that CETESB intends to reach in terms of monitoring of environmental radiation in Sao Paulo State are also presented. The levels observed, its implications in terms of health risks and possible causes of event are discussed too. On March, 1989, was detected contamination in a well near of the stores. The data comprises the period of 1983-1990 with information about concentration levels of radium-225 in underground and superficial waters of the region. in the municipality of Itu, Sao Paulo State, are presented. The results of environmental radiation monitoring that CETESB (Technological Company of Environmental Sanitation of Sao Paulo) does in influence areas of radioactive materials store of Nuclemon Minero-Quimica S.A.
