background: free-living amoebae (fla) are a group of ubiquitous protozoan, which are distrib­uted in the natural and artificial environment sources. the main aim of the current study was to identify the presence of fla in the recreational hot springs of sarein in ardebil province of iran. methods: seven recreational hot springs were selected in sarein city and 28 water samples (four from each h...

Fumarolic condensates and acid spring waters from Satsuma-Iwojima were sampled between 1993 and 1998 and analyzed for 129I/I and 36Cl/Cl ratios and chloride, bromine, and iodine concentrations. Halogen concentrations suggest that the fumarolic condensates represent mostly magmatic fluids, but that the hot springs are a mixture between magmatic fluids and meteoric water with some presence of sea...

The present work provides hydrochemical and stable isotope data and their interpretations for 54 springs and 20 wells, monitored from 2002 to 2006, in the Southern Latium region of Central Italy to identify flow paths, recharge areas and hydrochemical processes governing the evolution of groundwater in this region. The hydrogeological conceptual model of the carbonate aquifers of southern Latiu...

Physical and chemical barriers separate individual terrestrial hot springs and their affiliated communities of thermophilic bacteria. However, 16S rRNA gene sequence comparisons suggest that seemingly identical or closely related bacterial species are found in multiple hot springs that are separated by distances that range from a few meters to thousands of kilometers. To investigate whether thi...

Introduction Natural and artificial radionuclides are the main sources of human radiation exposure. These radionuclides, which are present in the environment, can be dissolved into water. Evidence suggests that radionuclides being entered the human body through drinking or hot spring water can be harmful for human health. Materials and Methods In this study,10 samples were collected from ground...

abstract background and purpose:cholera is an endemic disease in iran and in some cases each year from around the country report. the aim of this study was to evaluate the prevalence of the disease cholera among people suffering from acute diarrhea in the aranvabidgol. materials and methods:in this study, patients with acute diarrhea were examined for cholera detection in the city of aranvabidg...

ABSTRACT Springs of the Vacacaí-Mirim river basin, in Atlantic Forest biome, are protected by law because they provide an environmental service through water supply. No study provided identification, estimates and information about seasonality resilience conditions these springs, which supply central region state Rio Grande do Sul, Brazil. This monitored headwater flow volume interpreted result...
