Geofungos no Córrego do Sapateiro, Parque Municipal do Ibirapuera, São Paulo, SP, Brasil

No Córrego do Sapateiro, situado no Parque Municipal do Ibirapuera, na cidade de São Paulo, SP, Brasil, amostras de água (50 mL) na profundidade de 10 centímetros foram coletadas em locais antes (local 1) e depois (local 2) da estação de tratamento de flotação, durante os meses da estação chuvosa e quente (janeiro, fevereiro e março) e da estação seca e fria (junho, julho e agosto) de 2008. Além disso, a temperatura, oxigênio dissolvido, condutividade e pH da água foram medidos com um equipamento Horiba U10. Coliformes totais e fecais foram analisados com o kit Aquatest®. A partir de cada amostra de água, alíquotas de 1 mL foram inoculadas em meio batata-dextrose-ágar, totalizando 10 placas de Petri para cada local de coleta. Após incubação por 10 dias a 22 ºC, as colônias fúngicas foram quantificadas, purificadas e identificadas. Os parâmetros abióticos da água não foram limitantes para a presença de geofungos, sendo influenciados pelo tratamento de flotação. Nos dois locais o número de coliformes totais e fecais foi predominantemente superior a 8 NMP dL-1 durante o período estudado. Vinte e sete táxons de fungos foram obtidos, distribuídos em 136 ocorrências. de acordo com o índice de similaridade de Sörensen, a micota dos dois locais coletados foram consideravelmente diferentes, apesar da semelhança entre o número de táxons e ocorrências. Os resultados indicam que o tratamento da água do Córrego do Sapateiro pelo sistema de flotação possivelmente causa modificações na composição taxonômica e na quantidade de UFC de fungos, ao contrário do que ocorreu com os coliformes totais e fecais, cujos resultados apresentaram-se menos conclusivos.

A gestão da inclusão escolar na rede municipal de São Paulo: algumas considerações sobre o Programa Inclui

Para análise da questão da gestão política do processo de inclusão escolar, este artigo aborda o movimento da rede municipal de São Paulo em direção à uma escola inclusiva através da oferta de respostas educativas aos alunos com necessidades educacionais especiais. Assim, descreve o Programa Inclui, em andamento na rede municipal de ensino, que busca organizar, através de projetos, a construção e consolidação de um sistema inclusivo, na perspectiva de estar articulado com as práticas e ações político-pedagógicas que ocorrem desde a educação infantil ao ensino médio e se concentra nas ações necessárias para o atendimento às necessidades educacionais especiais para que se garanta a desejável relação entre educação comum e especial no enfrentamento das dificuldades do processo de ensino e aprendizagem daqueles que precisam de recursos, técnicas, metodologias diferenciadas para que sua trajetória escolar esteja garantida, no cotidiano, assim como está garantida no aspecto legal.

Geoenvironmental site investigation using different techniques in a municipal solid waste disposal site in Brazil

Different geoenvironmental site investigation techniques to assess contamination from a municipal solid waste disposal site in Brazil are presented here. Superficial geophysical investigation (geoelectrical survey), resistivity piezocone penetration tests (RCPTU), soil samples collected with direct-push samplers and water samples collected from monitoring wells were applied in this study. The application of the geoelectrical method was indispensable to identify the presence and flow direction of contamination plumes (leachate) as well as to indicate the most suitable locations for RCPTU tests and soil and water sampling. Chemical analyses of groundwater samples contributed to a better understanding of the flow of the contaminated plume. The piezocone presented some limitations for tropical soils, since the groundwater level is sometimes deeper than the layer which is impenetrable to the cone, and the soil genesis and unsaturated conditions affect soil behavior. The combined interpretation of geoelectrical measurements and soil and water samplings underpinned the interpretation of RCPTU tests. The interpretation of all the test results indicates that the contamination plume has already overreached the landfill's west-northwest borders. Geoenvironmental laboratory test results suggest that contamination from the solid waste disposal site has been developing gradually, indicating the need for continuous monitoring of the groundwater.

Potential of municipal solid waste (MSW) as a source of energy in São Paulo: Its impact on CO2 balance

Energy generation is needed in São Paulo and MSW represents a promising alternative, although it is more expensive than hydroelectric power. About 14 900 t/day of MSW is generated, of which 8433 t/day is domestic and commercial MSW. From this amount, 1800 t will be destined to generate 30 MW of power. The eco-balance of CO2 has been considered for incineration and recycling. The recycling program of plastics, metals, paper and glass would represent a significant reduction in energy and CO2 emission. The total CO2 released is 3.34 x 10(5) t/yr without recycling. and is 1.25 x 10(5) t/yr with a recycling program. Most of the CO2 comes from plastics and paper production. Economic aspects could probably favor Incineration with energy production as the best option. (C) 1998 Published by Elsevier B.V. Ltd. All rights reserved.

Determination of organochlorine pesticides and polychlorinated biphenyls residues in municipal solid waste compost by gas chromatography with electron-capture detection

A simple and efficient method for the simultaneous gas chromatographic determination of ten organochlorine pesticides (alpha-HCH, beta-HCH, gamma-HCH, p,p'-DDT, o,p'-DDT, p,p'-DDD, p,p'-DDE, aldrin, endrin, and dieldrin) and six congeners of PCBs (PCB 28, 52, 118, 138, 153, and 180) in municipal solid waste compost is described. The procedure involves a solid-phase dispersion matrix using celite as dispersant sorbent, alumina as clean up sorbent and hexane-dichloromethane (7:3, v/v) mixture as eluting solvent. An additional purification step with copper was necessary to eliminate sulphur. Analysis of the sample was performed by GC-ECD. The method was validated with fortified samples at two concentration levels (0.025 and 0.05 mg kg(-1)). Average recovery ranged from 77 to 121% with relative standard deviation between 1 and 18%. The detection limits, which ranged from 0.003 to 0.01 mg kg-1, were lower than those established by the Baden-Wurttemberg directive (0.033 mg kg(-1)).

Seroprevalence of bovine leptospirosis in Garanhuns municipal district, Pernambuco State, Brazil

The prevalence of Leptospira interrogans serovars in dairy cattle was determined by analyzing 464 serum samples from cows on 15 properties in Garanhuns municipal district, Pernambuco State, Brazil. A microscopic seroagglutination test including 12 serovars of Leptospira interrogans as antigens was used. Samples with titres 3 100 were considered positive. Two hundred and twenty-one (47.63%) of the samples were positive to one or more serovars. The prevalence of the serovars was hardjo (21.98%), bratislava (15.73%), castellonis(11.64%), tarassovi (10.56%), pyrogenes(1.72%), icterohaemorrhagiae (1.08%), pomona (0.86%), wolffi (0.86%), grippotyphosa (0.86%), djasiman (0.43%), canicola (0.21 %), and copenhageni (0.21 %).

Afecções oculares em crianças de 2 a 8 anos da rede pública municipal de Piracicaba - SP

Study model: observacional, retrospective. Objective: to determine the frequence of the ametropic errors and other ocular problems in children with 2 to 8 year-old at Piracicaba - SP. Patients and Method: During the school year of 2000, 1001 children enrolled at the public schools of Piracicaba - SP, age ranged from 2 to 8 years old, were referred to complete ophthalmological exam. Visual acuity was previously determined using Snellen chart, applied by school teachers. Those children presenting visual acuity equal or less than 0.8, visual complaints or visual disorders were selected to appointment. Results: 51 children (5.09%) did not attended to examination. 950 children were submitted to complete ophthalmological exam. Ametropic errors were found 70.84% of the children. The most prevalent refractive errors were Hypermetropic Astigmatism (49.62%) and Hypermetropia (32,98%). Anisometropia was found in 1.78% children. Other ocular disabilities accounted for 10.21% of the examined children, such as strabismus (3.36%), eyelid changes, allergic conjunctivitis, congenital dacryostenosis, optic atrophy, corioretinitis and congenital glaucoma. Conclusion: The frequence of ocular problems observed let us to conclude the screening programs are valid surveys on decreasing rates of preventable blindness in our country.
