In this study, PM2.5 samples were collected from September 2017 to August 2018 in Shijiazhuang, a city located on the North China Plain, and NO3concentration, δO-NO3 and δN-NO3 values in PM2.5 were analyzed. NO3 concentrations increased as PM2.5 levels increased during both polluted and ...
Results of analyses showedth at orchardgrass and tall rescue were significantly higher in percent NO3-Nth an either smooth brome or reed canarygrass. Tall fescue tended to be high in percent NO3-N the fall. Thus, as with sudangrass (Sorghum vulgate sudanense) and orchardgrass, tall rescue ...
Nitrate (NO3 -), a product of nitrogen oxidation, is a naturally occurring ion in the environment and integrated into complex organic molecules such as proteins and enzymes required by living systems. Nitrate is a more stable form of oxidized nitrogen than nitrite; however, it can be reduced ...
The twenty six trial fields covered a dozen different types of soil from the Montreal to the lower St. Lawrence River regions. As revealed by nitrate analysis (NO3‐N) there was a marked positive correlation between crop yield, and nitrate nitrogen from the fifth to the seventh week for ...
In contrast, plants receiving NH4 at 14 ppm N appeared normal and had dry weight slightly higher than with NO3 at the same concentration. As NH4 concentration increased from 14 to 112 ppm N, plant growth, K, Ca, and Mg contents decreased while soluble NH4, in the tissue was greatly ...
Dr.Elizabeth N. Pearce MD, MSc, Dr.Lewis E. Braverman MD Nitrate Nitrate is about 240 times less potent than perchlorate as a competitive inhibitor of NIS.32 Nitrates occur naturally in soil and groundwater due to the decomposition of organic materials, and are present in plants. Sodium nitr...

Despite the recent achievements in urea electrosynthesis from co-reduction of nitrogen wastes (such as NO3−) and CO2, the product selectivity remains fairly mediocre due to the competing nature of the two parallel reduction reactions. Here we report a catalyst design that affords high selectivity...
