Rats given lOg/kg in the diet, plus 0.2% sodium nitrite in the drinking water, had a significantly increased incidence of liver tumors compared with controls. The carcinogenic response is attributed to the in vitro production of N-nitrosomorpholine. In another study morpholine alone produced a low number of tumors of the liver, lung, and brain, and it was suggested that an unknown nitrate source reacted with the morpholine to form the carcinogenic iV-nitrosomorpholine. ... 

The initial study on the MeO-TEMPO / Mg(N03)2 / NBS triple catalyst system in the oxidation of 1 indicated the necessity of all three components the TEMPO based catalyst, the nitrate source (MNT) and the bromine source (NBS). A large number of metal nitrates and nitrites were screened initially and the highest activity and aldehyde selectivity under comparable reaction conditions were recorded using Mg(N03)2 as the nitrate component. A number of organic and inorganic bromides soluble in HOAc were also screened and high reaction rates were found when NBS was used as the bromide source. The effect of the concentration of the individual components of the new triple catalyst system on the reaction rate, on the conversion of 1 and on the selectivity to 2 over 60 min reaction time is shown in Figure 1.

When nitrate is completely utilized, the accumulated organic matter has the same (5 N as the original nitrate source. Hence, in regions where the consumption of nitrate is complete over the course of the year, isotope fractionation during nitrate assimilation has only a transitory (i.e. seasonal) effect that disappears when integrated over the seasons of growth. From the perspective of paleoceanography, the d N of... 

Use Pyrotechnics, explosives, matches, fertilizers, other nitrates, source of 14C by nuclear irradiation. 

By analogy to the sulfur system, atmospheric nitrate sources can be distinguished into primary, gas phase, aqueous phase, and aerosol phase. Primary nitric acid emissions are considered to be small (U.S. EPA 1996) and can be neglected. 

Presence of nitrogen oxides Nitrate reduction in wetlands is often limited by the availability of nitrogen oxides including nitrate. Sources of nitrate in wetlands are point and nonpoint sources from adjacent watersheds, groundwater inputs, atmospheric deposition, nitrification of ammonium in aerobic zones, and nitrification of ammonium released from anaerobic soil layers either by diffusion, advection, or bioturbation. Nitrate loading to most wetlands... 

Al-propyl nitrate is a flammable liquid with boiUng point of 110.5 °C and density of 1.063. Its explosive property is not severe, thus that it is difficult to be detonated. The calculated explosion heat is 549 kcal/kg (water vapor). The lead-block value after rectification of the detonator is only 15 cm. The explosion limit of the mixture with air is 2-100 %. Its flash point is 20 °C and the ignition point in air is 176.7 °C. Its vapor, which is heavier than air, can spread around and be ignited by distant fire. Furthermore, the ignition flame would be returned to the -propyl nitrate source. Being heated, M-propyl nitrate would be exploded. A significant detonation could be happened if it mixes with diatomaceous earth with ratio of 71.5/28.50. The lead-block value is 230 cm. A/-propyl nitrate can be used as a sensibilizer in cloud detonation, a rocket propellant, and a promoter of cetane number for diesel oil.
