Satellite images have shown a dramatic decline in pollution levels over China, which is “at least partly” due to an economic slowdown prompted by the coronavirus, US space agency Nasa says.
Nasa maps show how levels of nitrogen dioxide have fallen this year, and compared to the same period in 2019.
It comes amid record declines in China’s factory activity as manufacturers stop work in a bid to contain the virus.
China has nearly 80,000 cases.
The virus has spread to more than 50 countries but the vast majority of infections and deaths are in China, where the virus originated late last year. Coronavirus spread hits Chinese manufacturing
Diary of a life in locked-down Wuhan
How deadly is the coronavirus? Nasa scientists said the reduction in levels of nitrogen dioxide – a noxious gas emitted by motor vehicles and industrial facilities – was first apparent near the source of the outbreak in Wuhan city but then spread across the country.The space agency noted that the decline in air pollution levels coincided with restriction imposed on transportation and business activities, and as millions of people went into quarantine.”This is the first time I have seen such a dramatic drop-off over such a wide area for a specific event,” Fei Liu, an air quality researcher at Nasa’s Goddard Space Flight Center, said in a statement.She added that she had observed a decline in nitrogen dioxide levels during the economic recession in 2008, but said that decrease was more gradual.Nasa noted that China’s […]
