Recently, according to scientists, north-eastern Cina is violating the international rule and is emitting the harmful gasses in the air which can affect the ozone layer on a big level. As per the reports, China has been emitting the gas on a high level which is banned because it is harmful to the ozone layer and the chemical name is Chlorofluorocarbon-11, China has crossed the level as the emission is increased by 7,000 tonnes.

The report was submitted by the co-lead author Sunyoung Park from Kyungpook National University in South Korea as he said, “Our measurements showed ‘spikes’ in pollution when air arrived from industrialized areas.” Back in the days of 1970s and 1980s, the CFC-11 was the highly consumed gas as it was used in the refrigerator and was also used to make foam insulations. The gas was banned in 1987 as per the ban of Montreal Protocol. Not only the Montreal Protocol was there to ban the gas as other industrial aerosols were also the part of the ban. The excessive use of the chemical dissolved 10-40 km above the surface of the earth, ozone layer from over Antarctica and Australia.

Lead author Matt Rigby, an atmospheric chemist at the University of Bristol, said: “CFCs are the main culprit in depletion of the stratospheric ozone layer, which protects us from the sun’s ultraviolet radiation.” The possibility of the change can only occur by the production of the new emissions as the ban declination was totally active by 2012 but the speed of the close of the use of gas decreased to half in between the years 2013 to 2017. “Our monitoring stations were set up in remote locations far from potential sources,” explained co-author Ron Prinn, a professor at MIT.” As per Luke Western, a post-doctoral researcher at the University of Bristol said, “We didn’t find evidence of increased emissions from Japan, the Korean peninsula or any other country,”
