Effect on nitrate concentration in stream water of agricultural practices : I. Annual nitrogen budgets
The hydrological and biogeochemical monitoring of catchments has become a common approach for studying the effect of the evolution of agricultural practices on water resources. In numerous studies, the catchment is used as a “mega-lysimeter” to calculate annual input-output budgets. However, the literature reflects two opposite interpretations of the trends of nitrate concentration in streamwat...
متن کاملConcentration of Nitrate in Bottled Drinking Water in Qom, Iran
Background & Aims of the Study: The global consumption of bottled water is growing with substantial growth in sales volumes on every continent. The highest growth rates are occurring in Asia and South America. Biological and chemical monitoring of these waters is necessary. The aim of current study was determination of nitrate concentration in bottled drinking water in Qom, Iran in 2012...
متن کاملConcentration of nitrate, nitrite and fluoride in drinking water and bottled water in Semnan city
Introduction: The safety of drinking water is one of the critical indexes concerning to health and hygiene of a society. Monitoring and controlling qualitative indices of water is of great importance. Therefore, this study aimed to investigate the quality of bottled water and urban drinking water in Semnan city with regard to the concentration of pollutant ions of nitrite and nitrate as well as...
متن کاملNitrogen and oxygen isotope fractionation during dissimilatory nitrate reduction by denitrifying bacteria
We report the first measurements of coupled nitrogen (N) and oxygen (O) isotope fractionation of nitrate by laboratory cultures of denitrifying bacteria. Two seawater strains (Pseudomonas stutzeri, Ochrobactrum sp.) and three freshwater strains (Paracoccus denitrificans, Pseudomonas chlororaphis, Rhodobacter sphaeroides) were examined. Among four strains of facultative anaerobic denitrifiers, N...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
