在中国，经济活动恢复后，空气污染迅速恶化。
能源和清洁空气研究中心宣布，这是一个追踪空气污染的独立机构。
CREC报告：
在新的电晕平静下来之后，由于经济活动的恢复，整个中国的空气污染状况似乎正在恶化。
研究小组于4月至5月进行调查

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.
