Ozone Hole Majestic Information


The decrease in the concentration of ozone in the stratosphere in such as way that it results in the formation of a thin layer of ozone often refers to as ozone hole.  The Stratosphere is around 10 to 50 km away from the earth surface. Ozone blocks the harmful ultraviolet radiation from the sun. Harmful ultraviolet radiation can have lots of noisome effect in the biota if gets in the earth surface unchecked.

Ultraviolet radiation is classified as the A, B ad C respectively. A has the longer wavelength hence low intensity, B in intermediate between A and C. A has the shorter wavelength so higher intensity and causes the massive damage. Ozone is meant to absorb all UV-A and Half of the UV-B radiation.

Due to the depletion of the concentration of the ozone molecules more UV radiation is striking in the earth.  Certain human activities are the culprit for the depletion of the ozone layer. The main culprit for the ozone layer depletion is the chlorofluorocarbons (CFCs), which breaks down the ozone molecules. The single chlorine molecule is believed to continuously destroy the ozone molecule for more than two years. It is estimated that single chlorine molecule can destroy hundred thousands of ozone molecules in the Stratosphere.

Two to fifteen parts per million ozone molecule in the stratosphere is the normal level of ozone in the stratosphere. The ten parts per million are considered as the adequate level of ozone in the stratosphere.

Facts


1. Effects


The decrease in the absorption of ultraviolet radiation in the stratosphere causes the increase in ultraviolet radiation on the earth surface. Ultraviolet radiation can cause lots of effect like the skin disease, heart disease, cataracts, high vitamin D production, and many effects to the biota.

Further, ozone formation in the troposphere due to the reaction with oxygen with ultraviolet radiation can be catastrophic. There are many unknown effects of high-intensity ultraviolet radiation. Ozone being strong disinfectant can be hazardous to different life forms.

2. Antarctic Ozone Hole


Scientist first observed this in the year 1975. Every spring of the year the concentration of ozone at the top of Antarctica get destroyed. The onset of the summer marks the rise in temperature and increases the recovery process of ozone.

3. Prevention of Ozone Depletion



Anthropogenic activities are the main culprit for the ozone depletion. As the individual one can use the ozone-CFC-free product or products that are labeled ozone friendly. It is essential for adequate maintenance of the air-conditioning devices frequently. Recycling of the material needs to be done especially the air-condition and refrigerators.
