Nitrogen Budget of South Korea Including Gaseous Nitrogen Oxides from 2012 to 2014

Control of Nitrogen Oxides

Indoor Nitrogen Oxides

Nitrogen monoxide (NO) and nitrogen dioxide (NO2) are gases produced by hightemperature combustion through reactions between nitrogen and oxygen. Both nitrogen in fuel and nitrogen in the air can participate in the reactions. Formation of NO can be followed by further oxidation into NO2 in the atmosphere. NO2 is the most toxic of the nitrogen oxides (grouped generically as NOx) and it is very i...

Nitrogen oxides emission from two beech forests subjected to different nitrogen loads

We analysed nitrogen oxides (N2O, NO) and carbon dioxide (CO2) emissions from two beech forest soils close to Vienna, Austria, which were exposed to different nitrogen input from the atmosphere. The site Schottenwald (SW) received 20.2 kg N ha−1 y−1 and Klausenleopoldsdorf (KL) 12.6 kg N ha−1 y−1 through wet deposition. Nitric oxide emissions from soil were measured hourly with an automatic dyn...

Relative mutagenicities of gaseous nitrogen oxides in the supF gene of pSP189.

Gaseous nitric oxide (NO), an environmental pollutant found in cigarette smoke and diesel exhaust, has been shown to generate mutations in aerobic in vitro assays. The objective of this study was to identify which oxides of nitrogen, formed in the gaseous phase from NO, possess mutagenic activity. Samples of the plasmid pSP189, in 1 M HEPES buffer, pH 7.4, were exposed to preparations of nitrog...

A case study of ozone production, nitrogen oxides, and the radical budget in Mexico City

Observations at a mountain-top site within the Mexico City basin are used to characterize ozone production and destruction, nitrogen oxide speciation and chemistry, and the radical budget, with an emphasis on a stagnant air mass observed on one afternoon. The observations compare well with the results of recent photochemical models. An ozone production rate of ∼50 ppbv/h was observed in a stagn...
