A Review of Adverse Effects and Benefits of Nitrate and Nitrite in Drinking Water and Food on Human Health

, 2017
Introduction: The problem related to water pollution of nitrates and nitrites is both an issue in Iran and also most parts of the world. Studies to evaluate the acute and chronic effects of nitrate and nitrite have demonstrated that different ...

Embedded Fe‐Cu Pairs Enable Tandem Nitrate‐to‐Ammonia Electroreduction

Advanced Materials, EarlyView.
A tandem Fe‐Cu pair catalyst, composing a single copper atom (Cu–N3) coordinated to adjacent iron clusters (Fe3N8), is designed. The electron‐deficient copper sites markedly enhance nitrate adsorption, while the electron‐rich iron clusters facilitate nitrite adsorption and water activation, thereby accelerating the electroreduction of nitrate and ...

Dietary Nitrate: Effects on the health of weaning pigs and Antimicrobial activity on seven probiotic Bifidobacterium spp. strains [PDF]

, 2007
The potential role of nitrite as an antimicrobial substance in the stomach may be of some importance in the ecology of the gastrointestinal tract and in host physiology. It has been shown that nitrite, under the acidic conditions of the stomach, may kill

Scalable Fabrication of Electrochemical Sensors Via Inkjet Printing of Functionalized Graphene for Pesticide Detection

Advanced Materials Technologies, EarlyView.
Inkjet printing enables uniform, reproducible, and stable deposition of nitrogen‐doped graphene acid (NGA) on screen‐printed electrodes, outperforming traditional drop‐casting. The resulting electrochemical sensor exhibits enhanced sensitivity, long‐term stability, and efficient imidacloprid detection.

Fish production, water quality, and the role of nitrification as an ammonia removal process in intensively aerated hybrid catfish ponds

Journal of the World Aquaculture Society
Six 0.1‐ha earthen ponds with 45 kW/ha of aeration capacity were stocked with hybrid catfish (Ictalurus punctatus x I. furcatus) ranging from 15,000 to 90,000 fish ha−1 in 15,000 fish ha−1 increments to analyze the effect of nitrogen loading on ammonia ...

Erythrocytes and Vascular Function: Oxygen and Nitric Oxide

Frontiers in Physiology, 2018
Erythrocytes regulate vascular function through the modulation of oxygen delivery and the scavenging and generation of nitric oxide (NO). First, hemoglobin inside the red blood cell binds oxygen in the lungs and delivers it to tissues throughout the body

Performance of Fe-N/C Oxygen Reduction Electrocatalysts toward NO2-, NO, and NH2OH Electroreduction: From Fundamental Insights into the Active Center to a New Method for Environmental Nitrite Destruction.

Journal of the American Chemical Society, 2016
Although major progress has recently been achieved through ex situ methods, there is still a lack of understanding of the behavior of the active center in non-precious metal Fe-N/C catalysts under operating conditions.
