Nitrogen Dioxide - an overview | ScienceDirect Topics Nitrogen Dioxide Nitrogen dioxide (NO2) is one of a group of highly reactive gases known as nitrogen oxides (NO x) NO 2 is the main source of nitrate aerosols, which form an important fraction of PM 2 5 and, in the presence of ultraviolet light, of ozone The major sources of anthropogenic emissions of NO 2 are combustion processes Breathing air with a high concentration of NO 2 can irritate
Forecasting O3 and NO2 concentrations with spatiotemporally continuous . . . Ozone (O 3) is a significant contributor to air pollution and the main constituent of photochemical smog that plagues China Nitrogen dioxide (NO2) is a significant air pollutant and a critical trace gas in the Earth’s atmosphere The presence of O3 and NO 2 has detrimental effects on human health, the ecosystem, and agricultural production Forecasting accurate ambient O 3 and NO 2
Metal oxide gas sensors for detecting NO2 in industrial exhaust gas . . . This article reviews the NO 2 gas sensor based on metal oxides Firstly, the hazards of NO2 and the major disadvantages of chemiresistive sensors based on metal oxides were discussed Then, different sensitive materials of chemical resistance sensors were discussed, including metal oxides (MO), conductive polymers and carbon-based materials
