Background & objectives: Nitrate contamination of drinking water is a common problem in many parts of the world that poses a serious threat to public health and environment. In this research, the performance of a new rotary electrocoagulation reactor model for removal of nitrate in presence or absence of turbidity has been investigated. Methods: In this study, aluminum and iron electrodes were...

nitrate contamination is one of the main risks for groundwater in agricultural areas. theevaluation of the effect of agricultural practices on groundwater nitrate concentration, especially in highlysensitive areas, is crucial for a correct land planning, and a good agronomic intervention scheduling. aim of this paper is to map the probability to exceed nitrate regulatory threshold applying a no...

Field experiments were carried out in Huantai County from 2006 to 2008 to evaluate the effects of different nitrogen (N) fertilization and irrigation management practices on water leakage and nitrate leaching in the dominant wheat–maize rotation system in the North China Plain (NCP). Two N fertilization (NF1, the traditional one; NF2, fertilization based on soil testing) and two irrigation (IR1...

limitation of water resources and necessity in profitable production, and consequentlyproductivity enhancement has taken crop production by means of unconventional water into consideration. inthis study, the effect of different levels of zeolite and nitrifying bacteria were investigated on nitrogenouscompounds absorption in a closed system of carp breeding with alfalfa. treatments of zeolites a...

Nitrate, the most oxidized form of nitrogen, is regulated to protect people and animals from harmful levels as there is a large over abundance due to anthropogenic factors. Widespread field testing for nitrate could begin to address the nitrate pollution problem, however, the Cadmium Reduction Method, the leading certified method to detect and quantify nitrate, demands the use of a toxic heavy ...

PURPOSE To estimate the nitrate levels in private wells located in different parts of Enugu and discuss the future health implications following chronic ingestion of well water. MATERIALS AND METHODS The map of Enugu was used to divide the city into many 25 units, using grid lines 1 cm apart. Cluster sampling method was used to collect samples. These samples were sent to two laboratories for ...
