2. Application of treated domestic sewage effluent on the quality indicators of an Oxisol cultivated with castor bean
ABSTRACT In semi-arid regions of developing countries worldwide it is necessary to develop low cost technology methods to acquire new water supplies. The objective was to evaluate the changes in the attributes of soil quality irrigated with treated sewage effluent. The treatments consisted of applying treated sewage effluent (TSE) and underground well water

4. High Uranium Concentrations in the Groundwater of the Rio de Janeiro State, Brazil, Mountainous Region
Unexpectedly high uranium concentrations, up to 930 µg L-1, approximately thirty times higher than the World Health Organization (WHO) guidance level, were observed in groundwater samples from the mountainous region near Rio de Janeiro City, the so-called “Região Serrana”, approximately 60 km from the city. This region is characterized by a large numbe

7. Presence of rotavirus and free-living amoebae in the water supplies of Karachi, Pakistan
ABSTRACT Rotavirus and pathogenic free-living amoebae are causative agents of important health problems, especially for developing countries like Pakistan where the population has limited access to clean water supplies. Here, we evaluated the prevalence of rotavirus and free-living amoebae (Acanthamoeba spp., Balamuthia mandrillaris, Naegleria fowleri) in dr

9. Water fluoridation in 40 Brazilian cities: 7 year analysis
Objectives Fluoride levels in the public water supplies of 40 Brazilian cities were analyzed and classified on the basis of risk/benefit balance. Material and Methods Samples were collected monthly over a seven-year period from three sites for each water supply source. The samples were analyzed in duplicate in the laboratory of the Center for Research in P

10. Seven years of external control of fluoride levels in the public water supply in Bauru, São Paulo, Brazil
Fluoridation of the public water supplies is recognized as among the top ten public health achievements of the twentieth century. However, the positive aspects of this measure depend on the maintenance of fluoride concentrations within adequate levels. Objective To report the results of seven years of external control of the fluoride (F) concentrations in t

12. Detecção e localização de vazamentos em tubulações utilizando sistemas acústicos e redes neurais / Leak detection and location in pipelines through acoustic method and neural networks
Pipeline networks are complex systems of ducts used nowadays for gas and chemical products transporting through long distances. They frequently cross highly populated regions, water supplies or natural reserves. Even small leaks in pipelines can lead to great losses of products and serious damages to the environment before it could be detected. With the purp
