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.
Nitrogen dioxide (NO 2) is an ambient trace-gas result of both natural and anthropogenic processes. Long-term exposure to NO 2 may cause a wide spectrum of severe health problems such as hypertension, diabetes, heart and cardiovascular diseases and even death.
Nitrogen dioxide (NO 2) is a reddish-brown gas with a distinctive pungent, foul smell at higher temperature. It is toxic, a major pollutant, a strong oxidant, and one of the chemical species of oxides of nitrogen (NOx). The atmosphere consists of 78% nitrogen by volume.

Nitrogen dioxide: Risk assessment, environmental, and health hazard. Sushil K. Pandey, Jaspal Singh, in Hazardous Gases, 2021. 22.1 Introduction. Nitrogen dioxide (NO 2) is a reddish-brown gas with a distinctive pungent, foul smell at higher temperature. It is toxic, a major pollutant, a strong oxidant, and one of the chemical species of oxides ...
Conclusion. We proposed a strategy of CO 2 mixed into air to enhance plasma-driven nitrogen oxidation conversion. Using a conventional DBD reactor, adding an appropriate amount of CO 2 to the air can significantly improve nitrogen conversion efficiency of air and achieve co-production of NO x and CO. By establishing a controlled experiment, we ...
Nitrogen dioxide (NO 2) is an important air pollutant due to its adverse effects on human health.Yet, current evidence on the association between NO 2 and the risk of breast cancer lacks consistency.
Abstract. Increased inputs of reactive nitrogen (N) by fertiliser production cause adverse effects on terrestrial and aquatic ecosystems as well as human health, through impacts on air, soil and water quality. The best quantified adverse impacts include: (i) the loss of plant diversity in terrestrial ecosystems and excess algal growth in ...
Nitrogen dioxide. Nitrogen dioxide is an oxidant gas which at high concentrations can cause acute pulmonary edema (e.g. silo filler’s disease). At levels usually experienced in ambient air (15–30 ppb as urban background levels) effects are difficult to find. At high concentrations (1000–3000 ppb usually with exercise) some changes in ...
Abstract. Nitrogen dioxide (• NO 2) is a radical gas that forms part of air pollution and is produced chemically, photochemically and by ionizing radiation in aqueous and non-aqueous solutions as well as by various endogenous pathways in biological systems. This review describes the: (i) sources of • NO 2; (ii) kinetics and mechanism of ...
