Rogue Chinese factories that damage ozone by using illegal gases



In May 2018, a surprising study found that the atmosphere had an "unexpected and sustained increase" in chlorofluorocarbons (CFCs). At that time, scientists could not accurately pinpoint the exact location of the polluting and ozone-damaging gas, but later media reports suggested it was leading to a rural industrial city in China.

Now, a new study confirms the rise of CFCs with a tonnage of 7,000 tonnes actually coming from northeast China, based on atmospheric observations.

"This is where high-frequency atmospheric observations from Gosan, South Korea, and Hateruma, Japan, together with global monitoring data and simulations of atmospheric chemical transport models, will examine regional CFC-1

1 emissions from East Asia," reads the study summary. "We show that emissions from mainland China in 2014-2017 are 7.0 ± 3.0 gigagrams (± 1 standard deviation) per year higher than in 2008-2012 and that the increase in emissions Mainly in the northeastern provinces of Shandong and Hebei. "

PLASTICS POLLUTION IN THE OCEANS OF THE WORLD COULD BE 2.5 BILLION. US Dollars HAVE IMPACT, STUDY SAYS Shandong and Hebei account for "a significant portion" of the increase in CFC-11 emissions of at least 40 to 60 percent; There was no significant increase in CFC-11 emissions in any other East Asian country or other regions of the world where the data are available.

It is unclear what the economic cost of new CFC-11 emissions would be A 2009 study found that future ozone pollution could lead to annual health costs of $ 580 billion (in 2000) "and that the mortality from acute exposure will exceed 2 million".

Fox News has turned to the Chinese Ministry of the Environment and Environment with a request for comment. According to a New York Times report, the ministry prepared to answer questions that the Times had asked about the ongoing investigation last week.

Dr. Matt Rigby, the lead author of the study, said the increase in CFC-11, which was widely used as a refrigerant and foam insulation, before being banned by the Montreal Protocol of 1987, was "unexpected" when he was and Son The team began to carry out its research.

CFC-11 was mainly used in foam blowing, so we looked at estimates of the amount of CFC-11 that can be trapped in insulation foams in buildings or refrigerators made before 2010, but the quantities were far too small to explain the recent rise, "said Rigby in a statement." The most likely explanation for this is that at least before the end of 2017, a new production took place. This is the period our work covers. "

Rigby spoke with news.com.au about the fact that the factories secretly produced CFC-11, backed by a few local government officials who turned a blind eye to it not quite surprising. "

Researchers have not yet determined exactly where the other CFC-11 emissions came from.

AIR POLLUTION MORE THAN SMOKING, NEW STUDY FINDS

" Our measurements are just Parts of North America, Europe and South Australia are vulnerable to the eastern part of China, West Japan and the Korean Peninsula and the rest of the AGAGE network, "added Professor Sunyoung Park. There are large parts of the world for which we have very few detailed information on the emissions of ozone depleting substances. "

Ozone is part of the earth's stratosphere To protect against the sun's harmful ultraviolet rays and as an adjunct.

Following the first study from 2018, there were reports that the international non-governmental organization Environmental Investigation Agency suspected Chinese mills of The Chinese authorities later eliminated some of these facilities and did not provide any further explanation, added news.com.au.

Although the facts do, some members of the Chinese government appear to take positive action. [19659003] "They were worried, it was clear, I think … that they will address this issue," said Paul Fraser, one of the co-authors of the study, in an interview with ABC Radio via news.com.au. Fraser added He added that he had not seen any signs that China had begun to reprimand the offending factories In 1985, scientists had found a disturbing ozone hole over Antarctica and Australia. It was put into effect by the United Nations Environment Program. Former United Nations Secretary-General Kofi Annan said it was "[p] the hitherto most successful international single agreement" and it has generally been considered successful, with ozone recovering each year.

One hundred and ninety-seven countries, including the US under former President Ronald Reagan and China, are signatories to the Montreal Protocol.
