Abstract Two propolis samples from Sao Paulo State were investigated by GC/MS. 39 compounds were identified, 8 being new for propolis. Both samples showed some similarities in their qualitative composition. In one of them, coumaric acid and its prenylated derivatives predo­minated, while in the other one triterpenic alcolhols were the main constituents.

The chemical composition and antifungal activity of the Ageratum conyzoidesessential oils, obtained from the leaves collected in Ibiúna (1), Ribeirão Pires (2) and Campinas (3) in the São Paulo state, Brazil, were investigated. The essential oils were obtained from A. conyzoidesleaves by hydrodestilation and analyzed by GC/MS. The chemical composition of the A. conyzoides oil collected in Ribeirão Pires and Ibiúna consisted mainly of precocene I and II. The essential oil from leaves collected in Campinas had only traces of precocene II and a highest proportion of precocene I, α-humulene and (E)-caryophyllene than the oils (1) and (2). The Aspergillus flavus growth was inhibited by essential oils (1) and (2) at 60 and 64%, respectively, and the oil (3) was inactive. On the other hand, the three essential oils inhibited the sporulation of the fungus for more than 120 days. The essential oils of leaves collected in sites that show similarities in the latitude, altitude and average temperatures, as Ribeirão Pires and Ibiúna, showed chemical composition and antifungal activity similar, either, which showed the importance of geo-ecological factors in production of metabolites of the plant.

Aim: In this study we described the causes of mortality in Brazil, its 5 geographic regions, and in the most populated cities of Sao Paulo State in order to contribute for development of prevention and intervention strategies. Methods: Data on causes of death and age distribution of the populations were collected from online public databases and then submitted to the 2001 World Health Organization age standardization of rates for better assessment. Results: Data showed that the main causes of death in Brazil and in all 5 geographic regions were diseases of the circulatory system. Neoplasms were the second most frequent cause of death in Brazil and in 3 regions (South, Southeast and Midwest). However, in the other 2 regions (North and Northeast) the second most common was associated to external causes, being neoplasms the third most often. Additionally, in the South and Southeast the third cause of deaths were from diseases of the respiratory system and from the external causes occupied the fourth position. Analyzing the most populated cities of Sao Paulo State it was observed that all of them have the same profile of the country. On the other hand, as speculated previously, in Piracicaba city, the most common cause of mortality was neoplasm. Conclusions: These findings showed that Brazil has a large spectrum of causes of death and methods to decrease the mortality rates should be implemented in a local scenario rather than a nation-wide approach, where each location has to focus on its most urging problem.

Abstract Propolis and plant secretions from three species, most frequently mentioned as botanical sources of the bee glue in Brazil (Baccharis dracunculifolia, Araucaria angustifolia and Eucalyptus citriodora) have been investigated using GC-MS. Based on chemical evidence, B. dracunculifolia was shown to be the main propolis source in São Paulo state. The antibacterial and antifungal activities of all four materials were also tested, the most active being propolis and Baccharis leaf exudate.

A New Species

A new species, Neea itanhaensis, is described from São Paulo State, Brazil. N. itanhaensis differs from the other Neea species by its inflorescences with verticillate branching and sessile or subsessile leaves with an acute or oblique base and prominent secondary veins on the abaxial surface that diverge at less than a 90º angle from each other. Illustrations and comments about the taxonomy, phenology, distribution, habitat, conservation status and etymology are provided for the new species.

Abstract. Two areas in the Atlantic Forest (São Paulo State, Brazil), with contrasting environments in respect of human occupation, were monitored from 1999 to 2001. One area named PEFI (23°38'08''-23°40'18'' S and 46°36'48''-46°38'00'' W) at an altitude of 798 m a.s.l., 526.4 ha in area and about 50 km from the sea, lies in a State Park within the largest metropolis of South America - São Paulo. The other area, named CUNHA (between 23°13'18'' and 23°16'10'' S and 45°02'53'' and 45°05'15'' W) about 1050 m a.s.l. with an area of 2854 ha and about 15 km from the sea, is also within a State Park in the Atlantic Forest, but is surrounded by rural areas and small villages. For each area, the rainfall and throughfall chemistry were examined and pH and Na+, K+, Mg2+, Ca2+, NH4+, Cl-, NO3- and SO42- as well as trace metals were determined. Compared with PEFI, CUNHA is characterised by low chemical fluxes and the largest differences are for the ions such as Ca2+, H+, NO3- and SO42- which are mainly anthropogenic in origin. Differences in throughfall chemical fluxes are linked to the nutritional status of the trees.

Studies were made on the seasonal variation and qualitative composition of the Appendicularia population from a limited area of the South Atlantic 25º09.5'S to 24º04.0'S latitude and 47º48.4'W to 46º00.4'W longitude at the São Paulo State coast off Cananéia and off Santos. The pattern of the seasonal variation was irregular for the most important species (O. longicauda). Some qualitative differences regarding the species composition are discussed.

ABSTRACT: This work evaluated the rainwater chemical composition and the annual atmospheric deposition in Sorocaba (São Paulo State), Brazil. One sampling point was chosen and forty samples were collected between January and December 2006. The analyses were performed for pH, electrical conductivity, sodium, calcium, potassium, magnesium, sulphate, nitrate, phosphate, alkalinity and chloride. The rainwater pH varied from 5.20 to 6.40, being Ca 2 + the main ion responsible for controlling the rainwater pH. The ionic concentration decreases in the following order: Ca 2 + >Na+ > K+ >Mg 2 + for cations and SO 2 − 4 >HCO− 3 >NO− 3 >Cl− >PO 3 − 4 for anions. The annual atmospheric deposition appears to be controlled by the following sources: mining activities and cement factories (Ca 2 + and HCO− 3 ), agricultural activities (K+, NO− 3 and PO 3 − 4 ), soil dust (Na+, Mg 2 + and HCO− 3 ) and fossil fuel burning (SO 2 − 4 ).  RESUMO: Este trabalho avaliou a composição química das águas pluviais e a deposição atmosférica anual na cidade de Sorocaba (SP). Um ponto de amostragem foi escolhido e quarenta amostras foram coletadas entre janeiro e dezembro de 2006. As amostras foram caracterizadas em relação ao pH, condutividade elétrica, sódio, cálcio, potássio, magnésio, sulfato, nitrato, fosfato, alcalinidade e cloreto. O pH das águas de chuva variou entre 5,20 e 6,40, sendo o Ca 2 + o principal íon responsável pelo controle do pH das águas de chuva. A concentração iônica diminui na seguinte ordem: Ca 2 + >Na+ >K+ >Mg 2 + para os cátions e SO 2 − 4 >HCO− 3 >NO− 3 >Cl− >PO 3 − 4 para os ânions. A deposição atmosférica anual parece ser controlada pelas seguintes fontes: minerações e fábricas de cimento (Ca 2 + e HCO− 3 ), atividades agrícolas (K+, NO− 3 e PO 3 − 4 ), poeira de solo (Na+, Mg 2 + e HCO− 3 ) e queima de combustíveis fósseis (SO 2 − 4 ).Palavras-chave: Sorocaba, composição da água de chuva, poluição atmosférica.
