Increase in Pollution Levels in Delhi Due To Firecrackers
दीपावली के बाद पटाखों से दिल्ली में प्रदूषण का स्तर बढ़ा
रविवार की देर रात तक पटाखे फोड़ने से दिल्ली में प्रदूषण का स्तर काफी बढ़ गया है। दिवाली की रात पटाखों पर प्रतिबंध के बावजूद, निवासियों ने नियमों को तोड़ा, जिसके परिणामस्वरूप सोमवार सुबह धुंध भरा धुआँ और हवा की गुणवत्ता में गिरावट आई।
Pollution Levels in Delhi
दिवाली के दिन, शहर ने शुरू में आठ वर्षों में अपनी सर्वश्रेष्ठ हवा की गुणवत्ता देखी थी, 24 घंटे का औसत वायु गुणवत्ता सूचकांक (AQI) शाम 4 बजे 218 था। हालांकि, पटाखों के लगातार फटने से प्रदूषण के स्तर में तेज वृद्धि हुई।
सुबह 7 बजे तक, AQI 275 तक पहुंच गया था, “खराब श्रेणी” में गिर गया। शादीपुर, अयानगर, लोधी रोड, पूसा और जहांगीरपुरी सहित कुछ क्षेत्रों में AQI 308 से 355 तक होने से “बहुत खराब” श्रेणी में प्रवेश किया गया।
PM2.5 के रूप में ज्ञात ठीक पार्टिकुलेट मैटर, जो श्वसन प्रणाली में गहराई से प्रवेश कर सकता है और स्वास्थ्य समस्याओं को ट्रिगर कर सकता है, इन क्षेत्रों में सुरक्षित सीमा 60 माइक्रोग्राम प्रति घन मीटर से छह से सात गुना अधिक हो गई।
देर रात पटाखे फोड़ने के कारण ओखला और जहांगीरपुरी सहित विभिन्न स्थानों पर PM2.5 की सांद्रता सुबह के शुरुआती घंटों में 1,000 माइक्रोग्राम प्रति घन मीटर से अधिक हो गई।
केंद्रीय प्रदूषण नियंत्रण बोर्ड के आंकड़ों के अनुसार, तुलनात्मक रूप से, दिल्ली में AQI पिछले वर्ष दिवाली पर 312, 2021 में 382, 2020 में 414, 2019 में 337, 2018 में 281, 2017 में 319 और 2016 में 431 दर्ज किया गया था।
दिवाली के एक दिन बाद AQI 2015 में 360 से 2021 में 462 और 2022 में 303 तक रहा है। AQI श्रेणियां “अच्छी” (0-50) से “गंभीर प्लस” (450 से ऊपर) तक होती हैं।
दिल्ली के निवासियों ने सप्ताह के अंत में साफ आसमान और भरपूर धूप का आनंद लिया क्योंकि दिवाली के ठीक पहले हवा की गुणवत्ता में काफी सुधार हुआ था। इस सुधार का श्रेय शुक्रवार को हुई रुक-रुक कर बारिश और प्रदूषक फैलाव के लिए अनुकूल हवा की स्थिति को दिया जाता है।
28 अक्टूबर से शुरू होकर, शहर ने दो सप्ताह तक बहुत खराब से गंभीर हवा की गुणवत्ता का अनुभव किया था, इस अवधि के दौरान राष्ट्रीय राजधानी के ऊपर एक धुंधला धुंध छा गया था।
पिछले तीन वर्षों से, दिल्ली ने दिवाली के दौरान शहर के भीतर पटाखों के निर्माण, भंडारण, बिक्री और उपयोग पर व्यापक प्रतिबंध लगाया है। पिछले साल, पराली जलाने में कमी, देर से बारिश, अनुकूल मौसम की स्थिति और एक प्रारंभिक दिवाली ने शहर को त्योहार के बाद गंभीर वायु प्रदूषण का अनुभव करने से रोका।
एक संख्यात्मक मॉडल-आधारित ढांचा, निर्णय समर्थन प्रणाली, ने अनुमान लगाया कि पड़ोसी राज्यों, विशेष रूप से पंजाब और हरियाणा में पराली जलाने से रविवार को दिल्ली में PM2.5 प्रदूषण.

Electric cars no cure for global warming, may increase pollution level: IEA
Driving electric cars and scrapping your natural gas-fired boiler won’t make a dent in global carbon emissions, and may even increase pollution levels.Higher electrification may lead to oil demand peaking by 2030, but any reduction in emissions from the likes of electric vehicles will be offset by the increased use of power plants to charge them, according to the International Energy Agency’s annual World Energy Outlook, which plots different scenarios of future energy use.
In order to significantly reduce harmful pollution by 2040, electrification will have to form part of a comprehensive package of policies to reduce power sector carbon emissions and improve energy efficiency, the Paris-based body that advises nations on energy policy said.
The clamor for global action to dramatically cut emissions has reached fever pitch in recent months following the publication of a United Nations report that called for annual investment of $2.4 trillion in clean energy to avoid irreversible damage to the world. A common belief is that the electrification of transport and heating systems will go a long way to meeting stringent pollution targets set out in the 2015 Paris Agreement.

High pollution levels, heavy congestion and cold weather normally cause brown-white smog in Tehran in autumn and winter days each year. Many blame the quality of gasoline and substandard cars for the poor air quality in the sprawling city. Iran’s Health Ministry estimated that about 80,000 people died due to pollution across the country in 2012. The ministry also said that pollution contributed to the premature deaths of 4,500 people in Tehran in the same year.
