ट्विन टॉवर गिरते ही दिल्‍ली-NCR में बढ़ेगा प्रदूषण, नोएडा में लंबा रह सकता है असर, CSE विशेषज्ञ बोले

नई दिल्‍ली. नोएडा में बनी सुपरटेक ट्विन टावरों (Super Tech Twin Towers) को गिराए जाने का दिन नजदीक आ गया है. इसके लिए इमारतों में विस्‍फोटक लगाने की प्रक्रिया भी पूरी कर ली गई है. 28 अगस्‍त को इन दोनों टावरों को ध्‍वस्‍त कर दिया जाएगा. भारी मात्रा में पैदा होने वाली धूल और मिट्टी के प्रदूषण से बचने और इमारत गिरने के दौरान सुरक्षित रहने के लिए आसपास की इमारतों में रहने वाले लोगों को भी एक दिन के लिए वहां से हटाया जाएगा. हालांकि पर्यावरण विशेषज्ञों की मानें तो मसला सिर्फ एक दिन की धूल-मिट्टी का नहीं है बल्कि इमारतों के गिरने से पैदा हुआ वायु प्रदूषण (Air Pollution) कई दिनों तक परेशान करेगा. इतना ही नहीं इस ध्‍वस्‍तीकरण से न केवल ट्विन टावर (Twin Tower) के इलाके में रह रहे लोगों को पर्यावरण प्रदूषण संबंधी दिक्‍कतें झेलनी पड़ेंगी, बल्कि पूरे दिल्‍ली एनसीआर में प्रदूषण (Pollution in Delhi-NCR) का स्‍तर बढ़ने का अनुमान है. सेंटर फॉर साइंस एंड एनवायरनमेंट के क्‍लीन एयर कैंपेन प्रोग्राम मैनेजर अविकल सोमवंशी कहते हैं कि ट्विन टावर को गिराने का काम वैसे तो पूरे नियम-कानूनों के अनुसार हो रहा है. ध्‍वस्‍तीकरण के दौरान होने वाली धूल के लिए वहां ऑटोमैटिक वाटर स्प्रिंकलर के साथ वाटर टेंडर मौजूद रहेंगे. इसके अलावा लोगों की सुरक्षा से लेकर बचाव के लिए हर चीज का ध्‍यान रखा जा रहा है लेकिन भारत में पहली बार इतनी बड़ी इमारतें विस्‍फोटकों से गिराई जा रही हैं, इसका असर दिल्‍ली-एनसीआर की हवा में दिखाई देगा. जब भी कोई छोटा मकान बनता है या छोटी इमारत ढहाई जाती है तो हफ्तों तक उस इलाके में धूल और मिट्टी फैल जाती है जबकि ये तो 100 मीटर से भी ज्‍यादा ऊंची और काफी बड़ी दो इमारतें हैं. अविकल कहते हैं कि यह एक अच्‍छी बात है कि इन इमारतों को इस मौसम में गिराया जा रहा है. जबकि हवा भी चल रही है और बारिश का भी मौसम है. अगर इमारतें गिरने के बाद बारिश (Rain) हो जाती है तो यह काफी अच्‍छा होगा. इससे उड़ती धूल, प्रदूषण के बड़े और छोटे कण बैठ जाएंगे. हवा में कम घुटन और प्रदूषण होगा और यह आसपास रहने वाले लोगों के लिए बेहतर होगा लेकिन अगर बारिश नहीं होती और तेज हवा चलती है तो ये मिट्टी के कण उड़कर दूर तक जाएंगे. यह निश्चित ही ट्विन टावर के आस-पास रह रहे लोगों को भी परेशान करने के अलावा दूर-दराज तक हवा में मौजूद रहेंगे और प्रदूषण को बढ़ाएंगे. इससे पूरा अनुमान है कि दिल्‍ली-एनसीआर के प्रदूषण स्‍तर में इजाफा होगा और खासतौर पर नोएडा की वायु गुणवत्‍ता पर असर देखा जा सकेगा. अविकल कहते हैं कि छोटी इमारतों में प्रदूषण को रोकने के लिए कई चीजें की जाती हैं. धूल पर पानी डालने के अलावा उस एरिया को हरे कवर से ढका जाता है लेकिन यह ज्‍यादा बड़ी बिल्डिंग हैं, उसके लिए इतनी ज्‍यादा सुरक्षा करना काफी मुश्किल है और फिर ऊपर से वह विस्‍फोट के माध्‍यम से गिराई जा रही है. लिहाजा इमारतों में विस्‍फोट के बाद जब तक पूरा मलबा उस जगह से साफ नहीं हो जाएगा. तब तक जैसे-जैसे हवा चलेगी, परेशानी होगी. केरल में टावर गिरने पर बढ़ा था प्रदूषण वे कहते हैं कि केरल के कोच्चि और मराडु में चार टावर गिराई गई थीं. उस जगह से मलबा हटाने में दो महीने से भी ज्‍यादा का समय लगा था. इससे वहां की वायु में प्रदूषण पांच गुना तक बढ़ा हुआ देखा गया था. वायु गुणवत्‍ता में आई इस खराबी का खामियाजा वहां के लोगों को स्‍वास्‍थ्‍य संबंधी परेशानियों के रूप में झेलना पड़ा था. नोएडा की ट्विन टावरों से भी काफी ज्‍यादा मलबा निकलेगा, जो एक से दो महीनों में जाकर पूरी तरह साफ होगा, ऐसे में वहां आसपास रहने वाले लोगों के लिए भी यह एक चुनौती से कम नहीं है. हालांकि काफी हद तक चीजें मौसम और हवा की गति पर निर्भर करेंगी.

North India most-polluted region in 2022 summers: CSE

North India emerged as the most-polluted region in the country in summers this year with Delhi-NCR being the hotspot, according to a new analysis by the Centre for Science and Environment (CSE). The green think-tank said the average PM2.5 concentration in north India in summers stood at 71 microgram per cubic metre. It was 69 microgram per cubic metre in east India, 54 microgram per cubic metre in west India, and 46 microgram per cubic metre in central India, it said. Northeast India (35 microgram per cubic metre) and South India (31 microgram per cubic metre) were cleaner compared to other regions, it said. In north India, Delhi-NCR was found to be the most-polluted sub-region, with Bhiwadi reporting the highest average PM2.5 concentration of 134 microgram per cubic metre. Manesar reported average PM2.5 concentration of 119 microgram per cubic metre, Ghaziabad (101 microgram per cubic metre), Delhi (97 microgram per cubic metre), Gurugram (94 microgram per cubic metre) and Noida (80 microgram per cubic metre), it said. PM2.5 summer average of Delhi-NCR region is almost three times the average of the cities in southern India. The CSE used granular real-time data from the Central Pollution Control Board's portal -- Central Control Room for Air Quality Management for the analysis. The data is captured from 356 official stations under the Continuous Ambient Air Quality Monitoring System (CAAQMS) spread across 174 cities in 26 states and Union territories. PTI GVS TDS TDS

Namibia says it will not replace the cheetahs India rejected as part of translocation project

Namibia has said it has no intention of replacing the three cheetahs that the Indian government rejected on the grounds that the animals were bred in captivity and would not be able to hunt, in an “unfortunate” blow to India’s ambitious translocation project. Namibia’s environment and forest ministry spokesperson Romeo Muyunda told The Independent on Tuesday the country cannot provide any more wild cats to India for its “Project Cheetah” as its own population of the species is limited. India’s ambitious plan to repopulate its extinct cheetah population suffered the setback as Namibia, one of the partner countries from where the animals were to be translocated, shot down the claims that the cheetahs were captively bred. “We deny such allegations and claims given by India. The cheetahs are not captive animals. They were captured when they were young and were exposed to hunting,” Mr Muyunda said in a statement. Namibia has no intention to give other cheetahs to replace the three rejected ones, he added. Mr Muyunda also termed the rejection “unfortunate” and said it was the Indian government that had handpicked the cheetahs that it later rejected. “It’s unfortunate that India is rejecting these cheetahs. As the government, we were not involved in the selection of the cheetahs earmarked for India, this was done between the Indian government and a nonprofit organisation called Cheetah Conservation Fund of Namibia in Otjiwarongo,” Mr Muyunda explained. The ministry was assured by the fund that the cheetahs were not captive, he added. The cheetahs that are to be sent to India are currently being quarantined in Namibia for their rehabitilation at the Kuno wildlife sanctuary located in India’s central Madhya Pradesh state. The rejected ones will be reintroduced back to the wild in Namibia amid concerns about monitoring, according to a local report. One concern over the project has been the already existing population of leopards, which experts have said could complicate the ambitious intercontinental project as the top two apex predators would be forced to compete for territory. Officials have also been using two elephants to locate and tranquilise leopards at the Kuno sanctuary to avoid the competition for territory, reported Delhi-based nonprofit Centre for Science and Environment’s environmental magazine Down To Earth. Yadvendradev Vikramsinh Jhala, the dean of the Wildlife Institute of India and one of the experts overseeing the conservation initiative, pointed out that the three selected cheetahs “were not able to catch wild prey”, reported The Times of India. Fewer cheetahs coming into the country could possibly mean a further delay in the implementation of the rehabilitation project. India’s federal environment and forest ministry had formally announced the launch of the project last month to “establish a viable cheetah metapopulation in India that allows the cheetah to perform its functional role as a top predator”. India and Namibia had signed a memorandum to this effect in July to bring back the cheetah into India, seven decades after the wild cats went extinct due to hunting. A similar agreement has been signed by South Africa as well. The Independent has reached out to India's environment minister Bhupender Yadav for comment.

A CSE evaluation Battered by heatwaves, excessive particulate air pollution

CSE’s nationwide evaluation says north India has suffered the utmost air pollution — Delhi-NCR a hotspot. PM2.5 common of NCR virtually 3 times the common of cities in southern India Day by day peak air pollution highest in east India — cities in Bihar file the best ranges Total common air pollution this summer time larger than final summer time Mega cities not probably the most polluted — smaller cities turn into the air pollution hotspots. Dominate probably the most polluted record for 2022 summer time. Bhiwadi in Rajasthan tops the record. Excessive summer time air pollution results of a mix of air pollution from autos, business, energy vegetation, waste burning, and mud sources and wind-blown mud, aggravated by warmth and arid circumstances CSE says “this requires stringent measures to chop emissions from all air pollution sources whereas making huge efforts to fight desertification, enhance soil stabilisation, green-wall by afforestation, scale back warmth island impact in cities, and management forest and crop fires throughout all areas” Discover the entire evaluation Click on right here New Delhi, August 24, 2022: The summer time of 2022 was not solely unusually scorching but in addition uncharacteristically excessive on particulate air pollution, particularly in north India. Excessive PM2.5 ranges had been noticed throughout a number of cities and areas, and air pollution has not been confined to a couple mega cities or a particular area — it’s a widespread nationwide downside. This has emerged from the evaluation of summer time air high quality undertaken as a part of the air 2 high quality tracker initiative of the City Lab at Centre for Science and Setting (CSE). Summer season days from March 1 to Might 31 have been thought-about for the evaluation, as rains had set in throughout June in a number of areas. As availability of actual time air high quality information has improved in a number of areas with enlargement of the air high quality monitoring methods, it has turn into potential to evaluate the regional variations and perceive the distinctive regional tendencies. “This evaluation identifies the distinctive patterns of air pollution throughout all areas and places a highlight on numerous cities and cities that don’t get coverage consideration. Summer season particulate air pollution spikes resulting from arid circumstances, excessive summer time warmth and temperature, and extra airborne mud particles that journey lengthy distances compounding the issue from native sources,” says Anumita Roychowdhury, govt director, analysis and advocacy, CSE. “This air high quality tracker initiative has helped to benchmark the summer time air high quality for peerto-peer comparability inside every area and perceive the inter-regional variations that want to tell coverage motion. A number of areas skilled excessive particulate air pollution when warmth wave circumstances had been additionally widespread and intense,” says Avikal Somvanshi, senior programme supervisor on the City Lab. Information evaluation: This evaluation is predicated on publicly accessible granular actual time information (15- minute averages) from the Central Air pollution Management Board’s (CPCB) official on-line portal, Central Management Room for Air High quality Administration. The information is captured from 356 official stations underneath the Steady Ambient Air High quality Monitoring System (CAAQMS) unfold throughout 174 cities in 26 states and Union territories. Although there are a number of actual time displays in a couple of cities, many couldn’t be thought-about for this summer time air air pollution evaluation resulting from information gaps and lack of high quality information. Furthermore, in a number of circumstances, the true time displays have been arrange just lately and due to this fact, long run information is just not accessible. A number of cities of south and northeastern areas have procured their actual time displays in April 2022. Questions on high quality are being raised resulting from circumstances just like the one the place the CPCB has reported the identical information for Aurangabad in Bihar and Aurangabad in Maharashtra. Regional divisions: North India: Delhi, Uttar Pradesh, Punjab, Haryana, Rajasthan, Jammu & Kashmir Northeast India: Assam, Meghalaya, Mizoram, Tripura, Nagaland, Arunachal Pradesh West India: Gujarat and Maharashtra Central India: Madhya Pradesh and Chhattisgarh East India: Bihar, West Bengal, Odisha and Jharkhand South India: Andhra Pradesh, Karnataka, Kerala, Tamil Nadu, Telangana, and Puducherry Key findings North India is probably the most polluted, with Delhi-NCR being the summer time air pollution hotspot: Summer season common PM2.5 for North India stood at 71 µg/m³, the best amongst all of the areas. East India with 69 µg/m³ summer time common was the second worst. West India (54 µg/m³) and Central India (46 µg/m³) additionally recorded summer time degree entry of 40 µg/m³. Northeast India (35 µg/m³) and South India (31 µg/m³) had been the cleaner in comparison with different areas. Inside North India, Delhi NCR was discovered to be most polluted sub-region. The cities of Delhi-NCR recorded very excessive summer time PM2.5 averages, with Bhiwadi reporting the best summer time common of 134 µg/m³. Manesar (119 µg/m³), Ghaziabad (101 µg/m³), Delhi (97 µg/m³), Gurugram (94 µg/m³) and Noida (80 µg/m³). The PM2.5 common of NCR area is nearly 3 times the common of the cities in southern India. Day by day peak air pollution was highest in east India, with cities of Bihar recording the best ranges: Summer season every day peak PM2.5 ranges for East India stood at 168 µg/m³, the best amongst all of the areas. North India with 142 µg/m³ summer time peak was the second worst. West India (106 µg/m³), Central India (89 µg/m³), Northeast India (81 µg/m³) and South India (65 µg/m³) additionally recorded summer time peak in entry of 60 µg/m Inside North India, Delhi NCR was discovered to be most polluted sub-region. The cities of Bihar recorded very excessive summer time PM2.5 averages, with Bihar Sharif reporting the best summer time peak of 285 µg/m³. Katihar (245 µg/m³) and Patna (200 µg/m³) additionally recorded peak degree in entry of 200 µg/m³. Rohtak recorded the best peak air pollution in North India with a 258 µg/m³ every day peak. You will need to observe that mega cities usually are not probably the most polluted in any of the areas, it’s the smaller and upcoming cities which are air pollution hotspots. Common air pollution this summer time is larger than the earlier summer time: The regional PM2.5 ranges this summer time is larger in comparison with earlier summer time in North, Central, East and West areas, says Somvanshi. PM2.5 ranges stagnated in South India whereas Northeast registered a decline. North India have recorded a staggering 23 per cent improve in seasonal PM2.5 degree in comparison with the earlier summer time primarily based on a median of cities which have legitimate every day PM2.5 focus information of each summers (1 March to 31 Might). Inside North India, NCR was the worst performing sub-region with 25.8 per cent improve in seasonal PM2.5 degree. Central India registered improve of 15.6 per cent whereas West India (4.2 per cent) and East India (1.8 per cent) registered improve underneath 5 per cent. South India confirmed no change within the seasonal common however noticed a decline of twenty-two per cent in seasonal peak. Northeast India registered drop in each seasonal common (-12.8 per cent) and seasonal peak (-18.3 per cent). East India was the one area which registered a rise in its seasonal peak in comparison with final summer time Smaller cities and cities dominate probably the most polluted record for this summer time: Bhiwadi in Rajasthan was probably the most polluted metropolis in India this summer time with seasonal common of 4 134 µg/m³. Manesar in Haryana was the second most polluted metropolis with a seasonal common of 119 µg/m³. Singrauli in Madhya Pradesh is the third most polluted metropolis with seasonal common of 110 µg/m³. Rohtak, Haryana and Muzaffarnagar, UP are the opposite cities within the high 5 most polluted cities. 12 cities of Delhi-NCR function in high 20 cities with highest air pollution ranges this summer time. From peak summer time air pollution perspective Northern Haryana cities utterly dominate the record of most polluted with considerably worse 24-hr averages in comparison with remainder of the cities. Aizwal in Mizoram and Gummidipoondi in Tamil Nadu had been the least polluted cities within the nation this summer time. North India Northern cities with rising summer time air pollution tendencies: 19 cities within the area present rising development, i.e. each summer time common and peak elevated in comparison with their earlier summer time. Hapur in Uttar Pradesh noticed a staggering spike of 210 % in the summertime common and a peak common improve of 265 per cent. It was adopted by Kaithal in Haryana that registered 123 per cent improve in summer time common and 96 per cent improve in peak. Different cities that present improve embrace Muzaffarnagar, Panchkula, Kurukshetra, Rohtak, Ambala, Mandi Gobindgarh, Manesar, Udaipur, Yamuna Nagar, Bahardurgarh, Hisar, Gurugram, Kota, Ludhiana, Lucknow, Khanna, and Meerut. Northern cities with combined development within the common and peak ranges throughout summer time: 23 cities within the area present combined development, i.e. their summer time common has elevated however the peak air pollution declined in comparison with their earlier summer time. Solely Bhatinda is displaying decline of their summer time common (11 per cent) and improve of 1 % in peak air pollution in comparison with final summer time.

Because of arid and warmth circumstances and rising desertification, summer time months normally witness excessive mud impacts. However the mud can also be a service of poisonous substances from combustion sources together with autos, business, energy vegetation and burning of waste. Whereas the native nature of this downside must be investigated in all areas, this requires important tightening of motion to regulate emissions from every air pollution supply in addition to huge efforts to fight desertification, enhance soil stabilisation, green-walling by afforestation, and scale back the warmth island impact in cities.”

Science News: North India most-polluted region in 2022 summers: CSE

North India emerged as the most-polluted region in the country in summers this year with Delhi-NCR being the hotspot, according to a new analysis by the Centre for Science and Environment (CSE). The green think-tank said the average PM2.5 concentration in north India in summers stood at 71 microgram per cubic metre. It was 69 microgram per cubic metre in east India, 54 microgram per cubic metre in west India, and 46 microgram per cubic metre in central India, it said. Northeast India (35 microgram per cubic metre) and South India (31 microgram per cubic metre) were cleaner compared to other regions, it said. In north India, Delhi-NCR was found to be the most-polluted sub-region, with Bhiwadi reporting the highest average PM2.5 concentration of 134 microgram per cubic metre. Manesar reported average PM2.5 concentration of 119 microgram per cubic metre, Ghaziabad (101 microgram per cubic metre), Delhi (97 microgram per cubic metre), Gurugram (94 microgram per cubic metre) and Noida (80 microgram per cubic metre), it said. PM2.5 summer average of Delhi-NCR region is almost three times the average of the cities in southern India. The CSE used granular real-time data from the Central Pollution Control Board’s portal — Central Control Room for Air Quality Management for the analysis.
