The major part of emissions due to coal combustion is from power plants and nitrogen oxide emissions from this source are therefore considered in more detail including measurements of ground level concentrations relative to those from mobile sources. The environmental effects on health, plants, ...
When fuel is burned with air as the oxidant, some of the nitrogen in the air is oxidized to nitric oxide (NO). The amount in the combustion effluent depends on the flame temperature and the rate of cooling or quenching of the combustion products. Flame temperature is important because the ...
Outdoor air pollution: Sources, atmospheric transport, and human health effects G D Thurston, in Reference Module in Biomedical Sciences, 2023 Nitrogen oxides Nitrogen oxide (NOx) pollution is formed whenever fuel is combusted at high temperatures by a “fixing” of the nitrogen in the combustion...
For understanding the effects of N deposition on the response variables, the effect sizes (response ratio; RR) were computed following the equation of Hedges et al., (1999)78. For a given variable; the RR was estimated as the ratio of its value in the N treatment group (Xt) to that i...
Wu,Jun - 《Environmental Science & Pollution Research》 被引量: 1发表: 2017年 Evaluating the effects of micro-zones of granular sludge on one-stage partial nitritation–anammox nitrogen removal The total autotrophic nitrogen removal rate (TANRR) of the granular sludge increased as the granule size...
Here we use global emissions databases, a global nitrogen cycle model, and a global input-output database of domestic and international trade to calculate the nitrogen footprints for 188 countries as the sum of emissions of ammonia, nitrogen oxides and nitrous oxide to the atmosphere, and of ...
Ecological and toxicological effects of inorganic nitrogen pollution in aquatic ecosystems: a global assessment. Environ. Int. 32, 831–849 (2006). Article CAS PubMed Google Scholar Laane, R. W. P. M. Applying the critical load concept to the nitrogen load of the river Rhine to the ...
Cropland is a main source of global nitrogen pollution1,2. Mitigating nitrogen pollution from global croplands is a grand challenge because of the nature of non-point-source pollution from millions of farms and the constraints to implementing pollution-r
A method for treating/purification a gas containing nitrogen oxides (NOx) includes conveying same through a NOx trap containing a composition based on a catalyst for oxidizing NOx into NOand a compound based on zirconium oxide and praseo... N Kato,H Akimoto - 《Atmos.environ.a》 被引量: ...
Intensive measurement of nitrous oxide emissions from a corn–soybean–wheat rotation under two contrasting management systems over 5 years No-tillage (NT), a practice that has been shown to increase carbon sequestration in soils, has resulted in contradictory effects on nitrous oxide (N 2 O) e...
