"The reductions in air pollution in China caused by this economic disruption likely saved twenty times more lives in China than have now been lost due to infection with the virus in that country", Burke wrote on G-Feed, a site run by a group of scientists researching the relationship between society and the environment.
Based on actual pollution data from four cities in China from 2016 to 2019, he calculated that the pollution reduction was between 15 and 18 micrograms per cubic meter of air, or ug / m3.
The World Health Organization has estimated that about 7 million people die each year exposure to fine particles in polluted air.
The health damage inflicted on people by long-standing air pollution in cities is likely to increase the death rate from coronavirus infections, experts have said. As the pollution level in the city gets deteriorated day-by-day, doctors are advising residents to take precautions and avoid physical activity outdoors as much as possible when the pollutant levels are extremely high.
There is evidence from previous coronavirus outbreaks that those exposed to dirty air are more at risk of dying.
The EPHA cites a 2003 report that found that victims of SARS were 84% more likely to die if they lived in an area of moderate air pollution, compared to those who lived an area where it was low.
"The only way for India to fight COVID-19 or future pandemics would be if its environment is protected. In the context of the current COVID-19 pandemic, such individuals are likely to face severe complications", said the DFCA.Читайте также: Mnuchin: "We're looking at sending Americans checks immediately" during coronavirus crisis
"The reductions in air pollution in China caused by this economic disruption have probably saved twenty times more lives in China than those that have been lost now due to virus infection in this country", wrote Burke on G-Feed, a site managed by a group. of scientists researching the relationship between society and the environment. According to the Central Pollution Control Board (CPCB), the air quality in Delhi and adjoining areas continued to remain "very poor" as the Air Quality Index (AQI) at 9 a.m was recorded at 368. Since the outbreak, there has been a sharp drop in pollution levels in the region, according to satellite images taken on the 17 and 26 February. The level of PM2.5, risky small pollution particles, fell by 25%, while nitrogen dioxide, produced mainly by diesel vehicles, dropped by 40%.
The link between such pollutants and early deaths are well known and Marshall Burke, at Stanford University in the United States, used the data to estimate the impacts on air pollution mortality.
Based on those calculations, and considering a number of caveats, Burke calculated that the two months of cleaner air resulting from the coronavirus restrictions has saved the lives of between 1,400 and 4,000 children under 5, and 51,700 to 73,000 adults over 70 in China.
He said that indirect impacts of Covid-19 are probably much higher than now known.
Sascha Marschang, the acting secretary general of the European Public Health Alliance, said: "Once this crisis is over, policymakers should speed up measures to get dirty vehicles off our roads". "It seems likely that any "benefits" from reduced air pollution are going to be dominated by the direct and, especially, the indirect costs of the virus, [such as] the health effects of lost income and the morbidity/mortality costs of non-Covid health problems going untreated".
