Dosimeter for oxides of nitrogen

American Industrial Hygiene Association Journal, 1976
A simple, lightweight, prototype dosimeter, based on wet chemical principles, has been developed for personal monitoring of NO2. A simple modification provides for the determination of NOx. This device requires no auxiliary equipment and is intrinsically safe for use in coal mines.

Nitrogen oxide (NO) in the pathogenesis of preeclampsia

Bulletin of Experimental Biology and Medicine
The concentrations of nitric oxide (NO) donors in the plasma of pregnant women with preeclampsia is several times higher than in healthy pregnant women. Antihypertensive drugs acting not through the NO-mediated mechanisms normalized BP in some women with preeclampsia, but did not significantly reduce the levels of NO donors in the plasma.

The oxidation of Octopus vulgaris hemocyanin by nitrogen oxides

Biochemistry, 1989
The reaction of Octopus vulgaris hemocyanin with nitrite was studied under a variety of conditions in which the green half-met derivative is formed. Analytical evidence shows that the amount of chemically detectable nitrite in various samples of the derivative is not proportional to the cupric copper detected by EPR.

Reduction of nitrogen oxide (NO2) to nitrogen oxide (NO) by rush and other plants

Environmental Science & Technology, 1986
Previously the authors reported that rush carpets used in Japanese houses had the capacity to adsorb ambient NO/sub 2/ and the capacity endured for several years. The fate of adsorbed NO/sub 2/ was investigated in the present report. The outlet gas of a contacting tube packed with test material was monitored with a chemiluminescence analyzer for NO/sub

Oxidation of dicarboxycellulose by nitrogen oxides

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1960
In the oxidation of dicarboxycellulose by nitrogen oxides there is very strong hindrance to typical oxidation at C6 in the anhydroglucose units in fragments with an open pyran ring.

Oxidation of dialcoholcellulose with nitrogen oxides

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1961
1. The oxidation with nitrogen oxides of primary hydroxyl groups in the openglucopyranoside ring of the cellulose macromolecule was investigated. The typical reaction of the oxidation of the primary hydroxyl groups in the anhydroglucose unit is inhibited to a considerable extent in open glucopyranoside rings. 2.

The Biology of Nitrogen Oxides in the Airways

American journal of respiratory and critical care medicine, 1994
Abstract Nitrogen oxides (NOx), regarded in the past primarily as toxic air pollutants, have recently been shown to be bioactive species formed endogenously in the human lung. The relationship between the toxicities and the bioactivities of NOx must be understood in the context of their chemical interactions in the pulmonary ...

Nitrogen Oxidation in Ferrihaemoglobin Formation

Xenobiotica, 1971
Abstract1. N-Hydroxyarylamines, N-hydroxy-N-alkylarylamines, and N,N-dialkyl-arylamine-N-oxides form ferrihaemoglobin in the presence of oxygen; none of the compounds oxidizes ferrohaemoglobin directly.2. The hydroxylamines produce ferrihaemoglobin in a ‘coupled oxidation’ of the hydroxylamine of ferrohaemoglobin.

Oxides of Nitrogen

2006
The pamphlet explains the chemical qualities of oxides of nitrogen, sources of oxides of nitrogen emission, health and environmental effects, and monitoring trends. There is a brief summation about what is being done about oxides of nitrogen. The relationship between ozone and oxides of nitrogen is explained.

Review of the genotoxicity of nitrogen oxides

Mutation Research/Reviews in Genetic Toxicology, 1994
Nitrogen oxides (NOx) are formed in combustion processes and are major pollutants in urban air. Relatively few studies on the genotoxicity of NO2 and NO have been performed. These studies indicate that NO2 is genotoxic in vitro, but the effect of NO seems to be very slight.
