Stratospheric nitrogen dioxide in the Antarctic [PDF]
International Journal of Remote Sensing, 2005 Several UV-Visible spectrometers have been developed at the ISAC-CNR Institute. Differential Optical Absorption Spectroscopy (DOAS) methodology is applied to their measurements to monitor the amount of stratospheric trace gases: mainly ozone (O3) and nitrogen dioxide (NO2) deeply involved in the ozone cycle.

The Effects of Fine Dust, Ozone, and Nitrogen Dioxide on Health.
Deutsches Ärzteblatt International, 2019 BACKGROUND Air pollutants, especially fine dust, ozone, and nitrogen dioxide, pose a danger to health worldwide. In 2005, the World Health Organization (WHO), in order to protect public health, issued global recommendations for maximum levels of fine ...

Long-term Concentrations of Nitrogen Dioxide and Mortality
Epidemiology, 2018 Background: Concentrations of outdoor nitrogen dioxide (NO2) have been associated with increased mortality. Hazard ratios (HRs) from cohort studies are used to assess population health impact and burden. We undertook meta-analyses to derive concentration–

Associations between daily mortality in London and combined oxidant capacity, ozone and nitrogen dioxide. [PDF]
, 2014 Both nitrogen dioxide (NO2) and ozone (O3) are powerful oxidants in ambient air that are intimately linked through atmospheric chemistry and which continuously interchange over very short timescales.
