What are CFCS?

CFC chlorofluorocarbones are chemical compounds developed as an alternative to more dangerous chemicals for various applications. They were developed in the 1930s. However, although they represent less direct threats for individuals, they can provide an indirect threat to the global environment.

CFC contain several organic compounds and patterns may vary. However, the most common organic compounds used are carbon, fluorine, chlorine and hydrogen. These compounds are not toxic and are not flammable, which, ideally, is suitable for use as drives and other home use. One of the trade names of CFC is Freon, which is used as a coolant not only for refrigerators, but also for air conditioning units, both in vehicles and in houses. However, as the CFCS increased their trees, many did not realize how harmful they were in certain parts of the environment. UninhabitedTherefore, the use of chemicals over the years has begun to take a toll, especially on the ozone layer, a layer of the Earth's atmosphere, which helps to divert ultraviolet (UV) rays. CFC also contributes to global warming. Because of these problems, some countries, such as the United States, have largely banned the use of CFC.

The

ozone layer is very vulnerable, yet an essential part of the protection of the Earth from harmful UV rays from the sun. Many people concern the "hole" in Ozone, which developed in parts of the southern hemisphere, especially near and over Antarctica. Those who live on the southern tip of South America, South Australia and similar widths have noticed an increase in the harmful effects of stronger UV rays, including other cases of skin cancer and Issues' eyes.

The reason CFC is so harmful to the ozone layer is due to the presence of chlorine that is part of the compound. The sun's rays are working on the decay of CFC that jSOU relaxed into the atmosphere, and chlorine, which usually does not appear in very high concentrations in the atmosphere, begins to decompose the ozone layer. CFC has a life in the atmosphere anywhere from 20 to 100 years, which means that harmful effects can be felt for decades.

The harmful element that works on global warming is carbon. Carbon helps to maintain heat in the atmosphere and refuses to allow it to bounce back into space. As carbon is broken in CFC, the effects of global warming are reinforced.
