Certain fluorine-containing chemicals (especially the hydrochlorofluorocarbons) often cross the Montreal Protocol limits and become potential threats to the ozone layer as well as the global atmosphere. These unwanted gases deposit at Earth’s protective ozone layer and destruct it, which eventually causes global warming and deadly diseases. Global initiatives by environment protection organizations restricted the usage of several artificial greenhouse gases, but couldn’t stop the evolution of unexpected newcomers.
Recently, Martin K. Vollmer and co-researchers analyzed the air samples around the world for research purposes and found a new gas HCFC-132b (CH2ClCClF2), which can efficiently deplete the ozone layer. Later the group uncovered two other destructive gases namely, HCFC-133a (CH2ClCF3) and HCFC-31 (CH2ClF)!
Slowly but certainly, they are becoming serious threats to the ozone layer
Noticeably, these three new gases were never found so prominently in the global atmosphere in past and more astonishingly, none of these three gases are industrially useful.
According to their analysis, HCFC-132b appeared in the atmosphere 20 years back in East Asia, and probably due to lack of control, its global emissions increased to 1.1 Gg⋅y−1 by 2019. In early 2017, small emissions of HCFC-132b and HCFC-133a were found in southeastern France, and fluorocarbon production facility in that area was ceased immediately.
What are their sources!
Scientists are puzzled because these ozone-depleting gases are industrially useless! How did those start emitting then?
The group of environmental scientists suspects, these CFC gases are the by-products of some chemical production processes.
The good news is, scientists could detect, discover, and identify such unexpected emissions at an early stage; their presence in the global atmosphere is still very limited. Now it’s time to create strict environmental-industrial policies to stop these unwanted and potentially harmful emissions before they scale up and become a real threat to the ozone layer to burn the blue planet with deadly UV-rays.
As these gases have no purposeful end-use, it is definite to uncover the culprit chemical-processes that emit such threatening intermediates and cease the system at the earliest.
