Again, emissions from vehicles are a scapegoat, although based on environmental studies it is not just the pollution of vehicles using chlorofluorocarbon gas (CFC), known as Freon, used in air-conditioners (AC) and air-conditioning machines (central air-conditioning) for multi-level buildings and refrigerators are more dangerous and have more users than vehicle pollution.
Based on the research SINDOnews from various literatures that call CFC Gas more dangerous, even scientists chaired by Dr. Stephen Monzka of the American National Oceanic and Atmospheric Agency (NOAA). has discovered an unexpected rise in type 11 chlorofluorocarbons (CFCs), commonly known as CFC-11, which risks increasing ozone depletion in the earth's atmosphere.
After being banned from the Montreal Protocol, which was approved in 1987, it is said that the content of compound CFC-11 is decreasing as expected, but the process has been delayed since 2012.
Researchers say the evidence they find shows a new opportunity, namely illegal emissions of CFC-11 from undetectable regions in Asia
Many products we use in our daily activities use CFC gas, for example, perfume in the form of aerosols, air conditioners (AC) and even some models of refrigerators also use CFC gas.
CFC gas has several advantages, including odorless, tasteless, not easy to react and not dangerous directly. With some of these benefits, people then use CFC gas for developer purposes, such as hair spray (hair spray), perfume spray, development foam, coolers / refrigerators and air conditioners (freon).
True, CFC gas is not dangerous directly, but when we spray hair or perfume, the CFC gas that comes out will fly immediately, soaring into the sky and reaching the stratosphere.
There is an ozone layer (O3) in the stratosphere, and we know it as the protector of the earth from the sun's ultraviolet rays. If the CFC gas acts with the ozone layer (O3), a hole we know as an ozone hole will form. Because the ozone layer is hollow, the sun's ultraviolet rays directly penetrate and enter the earth. skin cancer, burning of the retina of the eye and death of algae and microorganisms.
Currently, the estimated size of the ozone hole is nearly three times the size of the European continent. What are the consequences if the ozone hole continues to grow wider? Think about it! To prevent the expansion and weight of ozone holes, the use of CFC gas is increasingly restricted. In developed countries, the use of CFCs has been stopped (banned) altogether, so now we can easily get goods without CFCs like refrigerators, air conditioners.
