COVID-19: Air pollution in China: worse than before coronavirus
COVID-19:
In China, air pollution quickly worsens when economic activity resumes.
Announced by the Center for Research on Energy and Clean Air, an independent body tracking air pollution.
CREC Report:
It seems that air pollution is worsening throughout China due to the resumption of economic activities after the new Corona has calmed down.
Research group surveys April to May
Particulate matter,
Nitrogen dioxide,
Sulfur dioxide,
measured ozone and so on.
Cause: Coal fired power plant
The cause of air pollution is mostly due to coal-fired power plants.
It seems that particulate matter, nitrogen dioxide, and sulfur dioxide increased rapidly, reaching the highest level.

Centre for Research on Energy and Clean Air BRIEFING:
China’s air pollution overshoots pre-crisis levels for the first time
May 18, 2020
Levels of health-harming air pollutants in China have exceeded concentrations at the same time last year in the past 30 days, for the first time since the start of the COVID-19 crisis.
This includes PM2.5, NO2, SO2 and ozone. Air pollutant levels plummeted during the national lockdown in February, bottomed out in early March
The rebound
appears to be driven by industrial emissions, as the pollution levels in the largest cities,
Beijing and Shanghai, are still trailing below last year.
More broadly, pollution levels tended to increase more in areas where coal-burning is a larger source of pollution.
Ozone levels are close to the record level of 2018.
