  • How have emissions reductions affected ozone control in China?
  • Sustained emission reductions have altered the prevailing regime for ozone formation over China, weakening the trade-off in pollution control between aerosols and ozone, according to analyses of ozone pollution chemistry between 2013 and 2021.
  • Why is Ozone used in water treatment?
  • Ozone is generally applied to treat surface waters and groundwaters for the production of drinking water . One major aspect regarding ozonation is defining the optimal location of the ozone application point in a treatment train, which depends on the treatment purposes .
  • What is the long-term trend of ozone pollution in China?
  • In the past decade, ozone (O 3) pollution has become a severe environmental problem in China's major cities. Here, based on available observational records, we investigated the long-term trend of O 3 pollution in China during 2014–2025. The O 3 concentrations were slightly higher in urban areas than in non-urban areas.
  • Does the National Air Pollution Control Programme reduce ozone level over China?
  • We evaluate the effectiveness of the national air pollution control programme, including Phase 1 (2013–2017) and Phase 2 (2018–2021), in reducing the ozone level over China, using an optimized machine learning approach, high-resolution emission estimates and an improved air quality model.
