China coronavirus Lockdown likely stored tens of thousands by cutting air pollution from factories and vehicles, according to a new analysis by a Stanford University scientist.

Professor of Earth System uses data from the US government censorship in four cities in China to measure the levels of PM2.5, tiny particulate deemed of air pollution. He was an average reduction of pollution levels and calculate the subsequent effect on the national death.

The two month reduction of pollution “may have saved the lives of 4,000 children under five and 73,000 adults over 70 in China,” he wrote, a blog managed by seven scientists working at the Food global, Environment and Economic dynamics.

to maintain a conservative calculation, Burke assumed no additional death for people between the ages of 5 and 70. Burke tested the prediction calculation more conservative mortality rate and still come up with 1,400 children rescued and 51 700 elderly.

“Even under these assumptions more conservative, the lives saved because of pollution reduction is approximately 20x the number of lives that have been lost to the virus directly,” Burke wrote, using current statistics on March 8.

Burke warned that its calculation is the prediction of the effect of death, not measurement. And his numbers do not include other negative consequences of the lock.

“But the calculations may be a useful reminder of the health consequences are often hidden from the status quo,” he wrote, that is- “which is a huge cost that our current way of doing things exacts on our health and livelihood.”

COVID-19 may help us to see these costs more clearly, he said.

“more broadly, the fact that disruption of this magnitude could really cause some of the benefits of (partial) shows that the way we normally do things that may need to interfere.”

the most dramatic effect in the southern Chinese cities such as Shanghai and Wuhan, he said, where the winter pollution comes mainly from cars and small industries.

They are likely to be repeated around the world as more countries enforce lockdowns. European Space Agency arrested disappeared pollutants nitrogen dioxide over northern Italy as a country that entered lockdown:

“The drop in emissions of nitrogen dioxide over the Po Valley in northern Italy which is very clear,” said Claus Zehner, the mission of ESA manager for satellite Copernicus Sentinel-5P. “Although there may be slight variations in the data due to cloud cover and change the weather, we are confident that the emission reductions that we can look to coincide with the lockdown in Italy led to less traffic and industrial activity.”

Deaths due to air pollution should also declined globally, according to the Energy Research Center and Clean Air.

“This abatement of pollution more than one month can mean tens of thousands of deaths avoid air pollution,” tweeted Center.

“That’s not to say that a pandemic is some kind of a blessing in disguise, with all the suffering that has been imposed on the people. At most, it shows it’s easy to overlook the chronic threat of long-term health such as air pollution, and thus, it is difficult to collect an adequate response. “

(lead analyst of The Center, Lauri Myllyvirta, that lockdown sweep net 25 percent of the carbon emissions of China in the first month, equivalent to 200 megatons of CO2, by reducing the consumption of coal, oil refining, air traffic and other sources.)

Meanwhile, the satellite has begun to level pollution record rise again in China as the government ease its lockdown:
