Winter pollution levels and trends point to national air quality crisis, says CSE’s latest analysis

New Delhi/IBNS: An all-India winter air quality analysis done by Centre for Science and Environment (CSE) says particulate pollution spiked and stayed elevated with varying intensity across all regions during the winter of 2021-22 (15 October to 28 February). Even though the overall regional averages of PM2.5 levels were lower than the previous winter in most regions, the winter smog episodes recorded severe spikes in several regions. Peak pollution was alarmingly high and synchronized, despite large distances within the regions – especially in the northern and eastern plains. The analysis has been done for the 2021-22 winter air quality tracker initiative of CSE’s Urban Data Analytics Lab. “Clearly, the winter pollution challenge is not limited to mega cities or to one specific region; it is now a widespread national problem that requires urgent and deliberate action at a national scale. This requires quicker reforms and action in key sectors of pollution – vehicles, industry, power plants and waste management to bend the annual air pollution curve and daily spikes,” says Anumita Roychowdhury, executive director, research and advocacy, CSE. “As availability of real-time air quality data has improved in several regions with the expansion of the air quality monitoring systems, it has become possible to assess the regional differences and the unique regional trends. This can help to inform the regional clean air action,” says Avikal Somvanshi, programme manager, Urban Data Analytics Lab, CSE. This air quality tracker initiative has helped to benchmark the winter air quality for peer-to-peer comparison within each region and inter-regional differences. This analysis is based on publicly available granular real time data (15-minute averages) from the Central Pollution Control Board’s (CPCB) official online portal Central Control Room for Air Quality Management. The data is captured from 326 official stations under the Continuous Ambient Air Quality Monitoring System (CAAQMS) spread across 161 cities in 26 states and union territories. Regional profile of winter pollution shows the eastern region is as polluted as Delhi-NCR: The winter average of PM2.5 in eastern plains that also include the newly monitored 19 cities and towns of Bihar, was the same as that of Delhi-NCR. Six Bihar towns feature in the top 10 most polluted cities this winter, with Siwan and Munger at the top. In the northern plains, Ghaziabad, Delhi, Faridabad, and Manesar are third, fifth, seventh and tenth in the list. Even though the seasonal average in smaller cities of Bihar rivals the mega-cities of NCR, their peak pollution during smog episodes are comparatively milder. The NCR cities have experienced the most severe daily (24-hr average) PM2.5 levels with Ghaziabad being the worst hit. Delhi, Noida, Faridabad, Greater Noida, and Gurugram are among the worst peak pollution (24-hr average) this winter. The PM2.5 winter average of the eastern region is over three times the average of the cities in southern India and 22 per cent more polluted than north Indian cities. Within the east, the Bihar sub-region is the most polluted. From the peak 24-hr PM2.5 level perspective, north Indian cities have recorded the highest daily pollution levels on an average. Within north, Delhi-NCR remains the most polluted sub-region with their worst days being almost five times the average. Its peak pollution is also almost five times higher the average peak of northeastern India cities (region with lowest peak pollution) and about 60 per cent higher than the average peak of eastern cities (region with the worst regional average).

Bihar, Delhi-NCR top pollution charts, air quality major crisis: CSE

The particulate pollution spiked and stayed elevated with varying intensity across all regions during the winter of 2021-22 (October 15 to February 28) with the PM2.5 winter average of the eastern region was over three times the average of the cities in southern India and 22 per cent more polluted than north Indian cities. This alarming observation was found in a detailed, all-India winter air quality analysis done by the Centre for Science and Environment (CSE) and released on Wednesday. Even though the overall regional averages of PM2.5 levels were lower than the previous winter in most regions, the winter smog episodes recorded severe spikes in several regions. Peak pollution was alarmingly high and synchronised, despite large distances within the regions – especially in the northern and eastern plains, the analysis said. The analysis has been done for the 2021-22 winter air quality tracker initiative of CSE’s Urban Data Analytics Lab. “Clearly, the winter pollution challenge is not limited to mega cities or to one specific region; it is now a widespread national problem that requires urgent and deliberate action at a national scale.

Delhi, Noida, Faridabad, Greater Noida, and Gurugram are among the worst that saw peak pollution (24-hr average) this winter. The PM2.5 winter average of the eastern region is over three times the average of the cities in southern India and 22 per cent more polluted than north Indian cities. Within the east, the Bihar sub-region is the most polluted. From the peak 24-hr PM2.5 level perspective, north Indian cities have recorded the highest daily pollution levels on an average. Within the north, Delhi-NCR remains the most polluted sub-region with their worst days being almost five times the average. Somvanshi said: “It is important to note that mega cities are not the most polluted in any of the regions — it is the smaller and upcoming cities that are becoming pollution hotspots. This is even more evident in the winter peak daily pollution data.”

Ghaziabad was essentially the most polluted metropolis amongst 60 north Indian cities final winter, adopted by Delhi, based on a contemporary air high quality evaluation. According to the “All India Winter Air Quality Analysis” carried out by the Centre for Science and Environment (CSE), particulate air pollution spiked and stayed elevated with various depth throughout all areas throughout the winter of 2021-22 (from October 15 to February 28). The evaluation accommodates an in depth evaluation of all of the areas — north, south, east, west, central and northeast. It mentioned essentially the most polluted metropolis within the northern area was Ghaziabad with a particulate matter 2.5 (PM2.5) common of 178 microgram per cubic metre (μg/m3), adopted by Delhi that had a winter common of 170 ug/m3. The subsequent seven spots are all occupied by neighbouring NCR cities — Faridabad, Manesar, Baghpat, Noida, Gurugram, Meerut and Hapur, it mentioned. The CSE, nonetheless, noticed that the north Indian cities have, on a mean, recorded 11 per cent decrease PM2.5 stage final winter, however the enchancment within the sub-region of Delhi-NCR was nearly eight per cent. “Delhi-NCR also saw a marginal increase in the average peak 24-hour pollution. The peak pollution rose significantly from the baseline among the cities in the south (24 per cent) and central Indian cities (7 per cent), despite the overall fall in the winter average,” it mentioned.

The CSE, however, observed that the north Indian cities have, on an average, recorded 11 per cent lower PM2.5 level last winter, but the improvement in the sub-region of Delhi-NCR was just about eight per cent. “Delhi-NCR also saw a marginal increase in the average peak 24-hour pollution. The peak pollution rose significantly from the baseline among the cities in the south (24 per cent) and central Indian cities (7 per cent), despite the overall fall in the winter average,” it said. In the northern region, Srinagar was found to be the cleanest city with Palwal in Haryana, Bathinda in Punjab and Alwar in Rajasthan among the cities with a relatively lower winter average. In the eastern region, the most polluted city was Siwan in Bihar while in the west, it was Ankleshwar in Gujarat. In the central region, Singrauli in Madhya Pradesh was the most polluted city while in south, Kalaburgi in Karnataka and Hyderabad in Telangana were found to be the most polluted cities. The most polluted city in the northeastern region was Guwahati in Assam with a winter average PM2.5 of 81 ug/m3.

नवीनतम वायु गुणवत्ता विश्लेषण के अनुसार, गाजियाबाद पिछली सर्दियों में 60 उत्तरी भारतीय शहरों में सबसे प्रदूषित शहर था, इसके बाद दिल्ली था। सेंटर फॉर साइंस एंड एनवायरनमेंट (सीएसई) द्वारा आयोजित “ऑल इंडिया विंटर एयर क्वालिटी एनालिसिस” के अनुसार, 2021-22 की सर्दियों (15 से 28 अक्टूबर तक) के दौरान सभी क्षेत्रों में पार्टिकुलेट मैटर प्रदूषण बढ़ा और अलग-अलग तीव्रता के साथ बढ़ता रहा। फ़रवरी)। मैं विश्लेषण में सभी क्षेत्रों – उत्तर, दक्षिण, पूर्व, पश्चिम, मध्य और उत्तर पूर्व का विस्तृत मूल्यांकन शामिल है। इसमें कहा गया है कि उत्तरी क्षेत्र में सबसे प्रदूषित शहर गाजियाबाद था, जिसमें 2.5 (पीएम 2.5) का औसत 178 माइक्रोग्राम प्रति घन मीटर (μg / m3) था, इसके बाद दिल्ली में 170 माइक्रोग्राम / एम 3 के सर्दियों के औसत के साथ था। अगले सात स्थानों पर एनसीआर के पड़ोसी शहर फरीदाबाद, मानेसर, बागपत, नोएडा, गुरुग्राम, मेरठ और हापुड़ का कब्जा है। हालांकि, सीएसई ने पाया कि उत्तर भारतीय शहरों में पिछली सर्दियों में औसत 11 प्रतिशत कम पीएम2.5 स्तर दर्ज किया गया था, लेकिन दिल्ली-एनसीआर उप-क्षेत्र में सुधार केवल आठ प्रतिशत था। “दिल्ली-एनसीआर में भी 24 घंटों में औसत चरम प्रदूषण में मामूली वृद्धि देखी गई। सर्दियों के औसत में समग्र गिरावट के बावजूद, दक्षिणी (24 प्रतिशत) और मध्य भारतीय शहरों (7 प्रतिशत) के बीच बेसलाइन से चरम प्रदूषण में काफी वृद्धि हुई है, ” इसे पढ़ें। उत्तरी क्षेत्र में, श्रीनगर हरियाणा में पलवल, पंजाब में बठिंडा और राजस्थान में अलवर के साथ अपेक्षाकृत कम सर्दियों के औसत वाले शहरों में सबसे स्वच्छ शहर पाया गया। पूर्वी क्षेत्र में, सबसे प्रदूषित शहर बिहार में सीवान था, जबकि पश्चिम में अंकलेश्वर गुजरात में था। मध्य क्षेत्र में, मध्य प्रदेश में सिंगरौली सबसे प्रदूषित शहर था, जबकि दक्षिण में कर्नाटक में कलबुर्गी और तेलंगाना में हैदराबाद सबसे प्रदूषित शहर पाए गए। पूर्वोत्तर क्षेत्र में सबसे प्रदूषित शहर असम में गुवाहाटी था, जिसका सर्दियों का औसत PM2.5 81 माइक्रोग्राम प्रति घन मीटर था। यह विश्लेषण CSE की अर्बन डेटा एनालिटिक्स लैब के 2021-22 विंटर एयर क्वालिटी ट्रैकिंग इनिशिएटिव के लिए किया गया था। “स्पष्ट रूप से, शीतकालीन प्रदूषण चुनौती मेगासिटी या एक विशिष्ट क्षेत्र तक सीमित नहीं है। यह अब एक व्यापक राष्ट्रीय समस्या है जिसके लिए राष्ट्रीय स्तर पर तत्काल और जानबूझकर कार्रवाई की आवश्यकता है। सीएसई की कार्यकारी निदेशक, अनुसंधान और वकालत अनुमिता रॉयचौधरी ने कहा, “वार्षिक वायु प्रदूषण वक्र और दैनिक चोटियों को मोड़ने के लिए प्रमुख प्रदूषण क्षेत्रों – वाहन, उद्योग, बिजली संयंत्र और अपशिष्ट प्रबंधन – में तेजी से सुधार और कार्रवाई की आवश्यकता है।” उन्होंने कहा कि जैसे-जैसे क्षेत्र राष्ट्रीय वायु गुणवत्ता मानकों को पूरा करने के लिए प्रतिस्पर्धा करते हैं, सर्दियों की स्थिति समस्या को और बढ़ा देती है। “हालांकि अधिकांश क्षेत्रों में महामारी की स्थिति ने सामान्य प्रवृत्ति को रोक दिया है, फिर भी एक मिश्रित प्रवृत्ति है। वार्षिक औसत प्रदूषण स्तर अपेक्षाकृत कम होने के बावजूद, सर्दियों के दौरान चरम प्रदूषण चरम पर हो सकता है। यह ठंडी और शांत सर्दियों की स्थिति के प्रभाव को इंगित करता है और क्षेत्रीय प्रभाव भी,” सुश्री रॉयचौधरी ने कहा। अविकल सोमवंशी, प्रोग्राम मैनेजर, अर्बन डेटा एनालिटिक्स लैब, सीएसई ने कहा कि वायु गुणवत्ता निगरानी प्रणाली के विस्तार के साथ विभिन्न क्षेत्रों में रीयल-टाइम वायु गुणवत्ता डेटा की उपलब्धता में सुधार हुआ है, क्षेत्रीय अंतर और अद्वितीय को समझना संभव हो गया है। क्षेत्रीय रुझान। सीएसई ने कहा कि इस वायु गुणवत्ता निगरानी पहल ने प्रत्येक क्षेत्र और क्रॉस-क्षेत्रीय अंतर के भीतर सहकर्मी से सहकर्मी की तुलना के लिए बेंचमार्क शीतकालीन वायु गुणवत्ता में मदद की है। विश्लेषण केंद्रीय प्रदूषण नियंत्रण बोर्ड (सीपीसीबी), वायु गुणवत्ता प्रबंधन के लिए केंद्रीय नियंत्रण कक्ष के आधिकारिक ऑनलाइन पोर्टल से सार्वजनिक रूप से उपलब्ध विस्तृत रीयल-टाइम डेटा (15 मिनट औसत) पर आधारित है। 26 राज्यों और केंद्र शासित प्रदेशों के 161 शहरों में फैले कंटीन्यूअस एम्बिएंट एयर क्वालिटी मॉनिटरिंग सिस्टम (CAAQMS) के तहत 326 आधिकारिक स्टेशनों से डेटा एकत्र किया गया है।

Bihar, Delhi-NCR top pollution charts, air quality major crisis: CSE

with the PM2.5 winter average of the eastern region was over three times the average of the cities in southern India and 22 per cent more polluted than north Indian cities. This alarming observation was found in a detailed, all-India winter analysis done by the Centre for Science and Environment (CSE) and released on Wednesday. Even though the overall regional averages of PM2.5 levels were lower than the previous winter in most regions, the winter smog episodes recorded severe spikes in several regions. Peak pollution was alarmingly high and synchronised, despite large distances within the regions - especially in the northern and eastern plains, the analysis said. The analysis has been done for the 2021-22 winter tracker initiative of CSE's Urban Data Analytics Lab. "Clearly, the winter pollution challenge is not limited to mega cities or to one specific region; it is now a widespread national problem that requires urgent and deliberate action at a national scale. This requires quicker reforms and action in key sectors of pollution - vehicles, industry, power plants and waste management to bend the annual curve and daily spikes," CSE's Executive Director, Research and Advocacy, Anumita Roychowdhury said.
