Chemicals Blamed for Ozone Destruction in the Arctic Region
Chlorofluorocarbon Substances Identified as Major Reason for Depletion
The devastation of the ozone layer in the Arctic region has reached an alarming level mainly because of chemicals coming from substances such as chlorofluorocarbons that are being used in appliances such as refrigerators and fire extinguishers.
Chlorofluorocarbon is described as an organic compound that contains carbon, chlorine and fluorine and produced as a volatile by-product of methane and ethane.
The damaging effects of this chemical were first recorded in the Antarctic, which is currently witnessing serious ozone reduction during winter, based on a report from the BBC.
90% of the earth's ozone is concentrated in the Stratosphere. Stratospheric ozone shields the earth from the damaging effects of ultraviolet radiation. Depletion of ozone can result in considerable increases in UV emission, which can lead to negative effects on human beings, animals and our ecosystems.
The ozone layer deters ultraviolet0B rays that cause skin caner and other ailments.
Scientists claim that ozone loss in the Arctic this year was so strong that it can be likened to what happened in the Antarctic region.
BBC gave details that 80 percent of ozone was lost 20 kilometers above the ground which caused a long spell of cold weather.
Chlorine chemicals are said to be most active under freezing conditions.
There were no records of low temperature for the current year but the air remained very cold for a longer period and covered a bigger area than before.
The glacial whirlpool was also stronger and winds moved all-around the periphery of the Arctic region rather cutting it off from the rest of the world's weather systems.
Ozone-draining conditions were observed to have extended into the earth's southern hemisphere which includes North, South and Central America.
Meanwhile, chlorine compounds have lived on in the upper atmosphere which indicates that the ozone layer will only be restored to a healthy status only by the middle of the century.
