Ozone Layer Depletion (ओजोन परत विनाश) - By Prof. SS Ojha - Geography Lectures

ओजोन परत विनाश
समताप मंडल में स्थित ओजोन परत, जिसे रसायन मंडल भी कहा जाता है, पृथ्वी के जीव मंडल के लिए एक कवच परत है। क्लोरो फ्लोरो कार्बन के विसर्जन द्वारा हम लोग ओजोन परत का विनाश कर रहे हैं । इस प्रकार ओजोन परत का विनाश ही ओजोन छिद्र कहलाता है ओजोन छिद्र से होकर पराबैंगनी किरणें पृथ्वी की सतह पर पहुंचकर गोरे लोगों में कैंसर, मुलायम फसलों जैसे -आलू, टमाटर इत्यादि की फसलों को क्षति मछली के लारवा तथा मुलायम लकड़ी वाले कोणधारी वनों को क्षति पहुंचाती हैं । ओजोन विनाश का प्रभाव स्थानिक तथा कालिक रूप से देखा जाता है । इसके विनाश का सर्वाधिक प्रभाव 60 से 65 डिग्री उत्तरी अक्षांश के ऊपर मार्च में तथा 60 से 65 डिग्री दक्षिणी अक्षांश के ऊपर सितंबर में होता है पृथ्वी पर सर्वाधिक विस्तृत ओजोन छिद्र अंटार्कटिका के ऊपर हैं ।
ओजोन संरक्षण हेतु विश्व स्तर पर सम्मेलन तथा शिखर वार्ता हो रही हैं जैसे मॉन्ट्रियल प्रोटोकॉल, रिओ पृथ्वी सम्मेलन तथा क्योटो प्रोटोकॉल इत्यादि। क्लोरो फ्लोरो कार्बन के स्थान पर हाइड्रो फ्लोरो कार्बन (HFCs) का भी प्रयोग किया जा रहा है l
Ozone Layer Depletion
Ozone Layer part of stratosphere also called chemo-sphere is known as protective layer of biosphere by releasing CFCs we are depleting O3 Layer. Does depression of thinning of a O3 layer is called O3 hole. Through O3 hole ultraviolet rays come on the earth and cause skin cancer in white, damage soft crap like potato tomato etc, damage Larva fish and softwood coniferous forest. Spatially and temporally O3 depletion is mostly notice in North hemisphere especially above 60 degree North 65 degree North belt in the month of March and over 60 degrees South 65 degrees South during September. The largest O3 hole has been recorded over Antarctica Continental.
For O3 conservation at global level a number of protocols and summits are being whole as Montreal protocol Rio Earth Summit Kyoto Protocol etc in place of CFCs, HFCs are how in use.
