Investigation into relationships among NO, NO2, NOx, O3, and CO at an urban background site in Delhi, India
TLDR
In this paper, high resolution measurements of high resolution concentrations of nitric oxide (NO), nitrogen dioxide (NO2), oxides of nitrogen (NOx), and Ozone (O3) were measured at a urban site (urban background) in New Delhi, India for a period of two years from September 2010 to August 2012.About:

TL;DR: The statistical analysis suggested that the PM2.5, PM10, and SO2 concentrations were significantly associated with precipitation (Prec), atmosphere temperature (T), and wind speed (WS), while the CO and NO2 concentrations displayed the significant relationship with T, while the O3 concentration was closely linked to the sunshine duration (Tsun) and relative humidity (RH).

TL;DR: In this article, the authors obtained the spatiotemporal characteristics of daily-averaged particulate matter (PM10 and PM2.5) and trace gases (NOX,O3,SO2, and CO) within a network of 12 air quality monitoring stations located over 2000 km2 across Delhi-NCR from January 2014 to December 2017.

Analysis of air quality characteristics of Beijing-Tianjin-Hebei and its surrounding air pollution transport channel cities in China
TL;DR: Air quality in Beijing-Tianjin-Hebei and the surrounding areas showed obvious seasonal characteristics, among which PM2.5, PM10, SO2, and NO2 showed a "U" type distribution from January to December, while O3 had an "inverted U" distribution.

Ambient particulate matter and carbon monoxide at an urban site of India: Influence of anthropogenic emissions and dust storms
TL;DR: In each season, the highest PM2.5/PM10 ratio coincided with the highest concentrations of pollutants (CO and NOX) indicating predominant emissions from anthropogenic sources.
Journal ArticleDOI
Impacts of the COVID-19 event on the NOx emissions of key polluting enterprises in China
TL;DR: COVID-19 significantly reduced the NOx emission levels of the key polluting enterprises in China, and among all industrial sectors, the mining industry, manufacturing industry, power, heat, gas, and water production and supply industry, and the wholesale and retail industry were the most heavily influenced.

TL;DR: In this large study, it was not able to detect an effect of ozone on the risk of death from cardiovascular causes when the concentration of PM(2.5) was taken into account, but a significant increase in the risk from respiratory causes was demonstrated in association with an increase in ozone concentration.

A review of surface ozone background levels and trends
TL;DR: A survey of the literature was conducted to review historical and current surface ozone data from background stations in Canada, United States and around the world for the purpose of characterizing background levels and trends, present plausible explanations for observed trends and explore projections of future ozone levels as discussed by the authors.
Journal ArticleDOI
Global air quality and pollution.
TL;DR: In the 1990s, nitrogen oxide emissions from Asia surpassed those from North America and Europe and should continue to exceed them for decades for decades.
