Radon and progeny (Pb-214 and Bi-214) in urban water-supply systems of São Paulo State, Brazil

Many water-supply systems in South America utilize the waters of the Guarani aquifer at least as part of their networks. However, there is little present knowledge in Brazil of the factors affecting Rn presence in the water supplied for end-users, despite the economic importance of Guarani aquifer. Rn-222 analyzes of 162 water samples were performed at 8 municipalities in São Paulo State, Brazil, with the aim of investigating the major factors affecting its presence in solution. The Rn-222 activity concentration ranged from 0.04 up to 204.9 Bq/L, with three samples exceeding the World Health Organization maximum limit of 100Bq/L. Aeration was confirmed as the most important factor for Rn release, as expected due to its gaseous nature. Accumulation in pipes and stratification in the water column were other significant factors explaining the data obtained in some circumstances. The Rn daughters Ph-214 and Bi-214 were also determined in a set of selected samples and their presence was directly related to the occurrence of Rn dissolved in water. (c) 2008 Elsevier Ltd.

La Formación Corumbataí y su importancia en la industria cerámica del estado de São Paulo - Brasil

El desarrollo acelerado del polo cerámico de Santa Gertrudes (provincia de São Paulo) en la década de 90, fue causado principalmente por la localización privilegiada de la materia prima asociada al desarrollo tecnológico, las grandes reservas, el acceso fácil por autopistas que facilitan la distribución de los productos y la proximidad de los grandes centros consumidores. Este desarrollo facilitó que este Polo tuviera un boom en el inicio de 2007 en la fase de madurez con una producción de 367 millones de metros cuadrados, transformándose así en el mayor polo cerámico de las Américas. de acuerdo con los estudios geológicos realizados en este trabajo, las rocas de la Formación Corumbataí, origen de la materia prima usada en el polo cerámico, fueron clasificadas en cinco litofacies: maciza, laminada, intercalada I, intercalada II y alterada. Estas litofacies, por sus características mineralógicas y químicas, fueron consideradas arcillas illíticas con porcentaje medio de fundentes. Tomando como referencia las Normas para baldosas cerámicas, las características cerámicas obtenidas en el laboratorio demostraron que la mayoría de la materia prima es compatible con el grupo BIIb (Absorción de agua entre 6 y 10%).

Diagnóstico ambiental de metais e organoclorados em córregos adjacentes a áreas de cultivo de cana-de-açúcar (Estado de São Paulo, Brasil)

Sugar cane cultivation in the State of São Paulo has expanded in the last years, with an annual production of 200 10(6) t in an area of 2.5 10(6) hectares. The use of herbicides, pesticides and fertilizers in sugar cane plantations, together with deforestation of riparian vegetation, have caused impacts on the hydric resources of the adjacent areas. The aim of this work is to evaluate the influence of sugar cane plantations on streams in the central region of the State of São Paulo, studying 16 organochlorinated compounds and 7 metals (Cu, Fe, Cd, Zn, Mn, Cr and Ni) found in the sediments of 11 streams. The results show that there is a higher concentration of metals and organochlorinated compounds in streams without riparian vegetation when compared to forested areas.

Anatomical characterization and chemical profile of Laguncularia racemosa (L.) Gaertn leaf blades, from impacted and non-impacted mangroves of the São Paulo Coast

Anatomical characterization and chemical profile of Laguncularia racemosa (L.) Gaertn leaf blades, from impacted and non-impacted mangroves of the São Paulo Coast. Several sources of environmental impact have caused great damage to the flora in mangroves. Therefore, this study aimed to analyze the anatomy and chemical composition of Laguncularia racemosa (L.) Gaertn leaf blades, from impacted (Municipality of Santos) and non-impacted mangroves (Municipality of Peruibe) of the São Paulo Coast. For the leaf anatomy studies, light microscopy and scanning electron microscopy (SEM) were used. For chemical analysis, high performance liquid chromatography (HPLC) was conducted. The biometry revealed leaf tissues of plants from impacted mangroves with a less thick epidermis and mesophyll and higher width of the central vascular beam. A smaller number of stomata and higher amounts of daises in these leaves were also observed. Results were confirmed by the Student t-test (alpha = 5%). The chemical profiles revealed a higher ammount of secondary metabolites in leaves from the impacted environment.

Seasonal variation of Alphitobius diaperinus population in broiler facilities in the center-north region of the state of São Paulo

The seasonality of Alphitobius diaperinus population was studied during different seasons during one year, in broiler facilities located in the center-north region of the State of São Paulo. Parasite counting was weekly carried out by the use of traps adapted from the modified model of Arends. During the experimental period, facilities were not submitted to chemical treatment, and the litter was changed between flocks. A lower number of adults and larvae was observed during autumn, with the peak registered in the summer. There was no significant difference between spring and winter averages (adults and larvae), and between spring and summer averages (adults). Average temperatures in the facilities varied from 23.4ºC (winter) to 27.1ºC (spring). The environmentally controlled systems used by the broiler industry provide an adequate habitat for A. diaperinus development. The continuous monitoring of the population of this parasite is essential for designing control strategies, and this can be accomplished by utilizing the traps used in the present experiment.

Evolução e determinantes de incremento de peso (por altura e idade) em crianças de dois a 72 meses em Sorocaba, São Paulo: evidências a partir de estudo quase-experimental seriado.

OBJETIVOS: recupera-se síntese dos principais aspectos das publicações referentes a projeto conduzido pela equipe, na década passada, com o objetivo de subsidiar a avaliação de política pública setorial de suplementação alimentar na infância. MÉTODOS: acompanharam-se trimestralmente, durante um ano, indicadores de crescimento e desenvolvimento em populações periféricas de dois a 72 meses de idade, em Sorocaba, São Paulo. Após realização do censo infantil de duas regiões da cidade, as crianças freqüentes a creches (em número de 164) foram comparadas às demais (280). O impacto nutricional foi quantificado através de análises univariadas (testes inferenciais Kappa e de Goodman) e multivariadas. Vieses e confundimento foram averiguados e controlados. RESULTADOS: observou-se, entre muitas outras informações obtidas, que o grupo assistido apresentou: 1) idade média superior; 2) menor taxa de aleitamento natural; 3) menores valores de peso/altura à admissão, com maiores ganhos durante a evolução; 4) essa melhora aumentou com a duração da exposição e foi maior entre os mais velhos. CONCLUSÕES: avalia-se que assistir apropriadamente pré-escolares constitui hoje, em nosso meio, relevante imperativo de ordem social.
