Monitoramento das águas subterráneas adjacentes ao aterro sanitário de Taubaté(SP): primeiros resultados

36 observation wells, varying from 2 to 5 meters in depth to water, were installed over a 20,000 m² area downgradient from the Taubate sanitary landílll as part of a project to monitor groundwater quality at the site. In 1984, the first year of the study, water leveis in the wells were measured monthly and water quality samples were collected and analyzed every 3 months. The chemical analyses results showed an increase in the overall mineralization of the groundwater in the vicinity of the landfill, particularly for chloride, soium bicarbonate, potassium, magnesium and ammonium ions. Good correlations were demonstrated between specific conductance and total dissolve d solids (TDS), which consiste d principally of chloride and sodium ions. For the geohydrologic environment studied, the best indicators of landfill pollution were: specific conductance, sodium, chloride and ammonium ionsForam instalados 36 poços de observação, de 2 a 5m de profundidade numa área de 20.000 m² a jusante do aterro sanitário de Taubaté a fim de se monitorar a qualidade das águas subterrâneas no local. Em 1984, primeiro ano do estudo, o nível de água nos poços foi medido mensalmente e foram coletadas e analisadas amostras de água de cada poço trimestralmente. Os resultados das análises químicas mostraram que a proximidade do depósito de lixo provoca o aumento da mineralização total da água subterrânea, e em particular das concentrações dos íons cloreto, sódio, bicarbonato, potássio, magnésio e amônio. Foram evidenciadas boas correlações lineares entre a condutividade e as concentrações de sólidos totais dissolvidos - de cloretos e de sódio. No ambiente hidrogeológico estudado, a condutividade, o sódio, o cloreto e o nitrogênio amordaçai constituem os indicadores da poluição pelo lix

Effects of Passiflora edulis on the Metabolic Profile of Diabetic Wistar Rat Offspring

Dry extract of the genus Passiflora has been shown to help control glycemia and lipid levels. The objective of this study was to evaluate the effects of passion fruit (P. edulis) on the biochemical profile of offspring from diabetic rats. Diabetes was induced by streptozotocin. The diabetes group consisted of 10 rats with glucose levels greater than 200 mg/dL; the nondiabetic (control) group consisted of 10 rats with glucose levels less than 120 mg/dL. After the diagnosis of diabetes, the mating phase was started. By day 21 of pregnancy, the offspring were born; the dams were kept in individual cages with their offspring until the weaning period. The offspring were then divided into 4 groups (n = 15 each): G1 were offspring from control dams, G2 were offspring from treated nondiabetic dams, G3 were offspring from diabetic dams, and G4 were offspring from treated diabetic dams. For 30 consecutive days, G1 and G3 offspring were treated with vehicle (oral gavage) and G2 and G4 offspring were treated with passion fruit juice (oral gavage). After 30-day treatment, the animals were anesthetized and killed, and blood was drawn immediately for analysis of the biochemical profile (total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, triglycerides, and glucose). The G2 and G4 rats showed significantly reduced total cholesterol, triglyceride, and low-density lipoprotein cholesterol levels and an increased high-density lipoprotein cholesterol level. The use of passion fruit juice improved lipid profiles, suggesting that this plant may have beneficial effects in the prevention and treatment of dyslipidemias and hyperglycemia
