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.

Delhi is the second most polluted North Indian city. The first is…

According to the latest air quality analysis, Ghaziabad was the most polluted city among 60 North Indian cities last winter, followed by Delhi. According to the “All India Winter Air Quality Analysis” carried out by the Center for Science and Environment (CSE), particulate pollution increased during the winter of 2021-22 (from 15 October to 28 February) and with varying intensity over all regions. Stay high. , The analysis includes a detailed assessment of all the regions – North, South, East, West, Central and North East. It said the most polluted city in the northern region was Ghaziabad, with a particulate matter 2.5 (PM2.5) average of 178 micrograms per cubic meter (μg/m3), followed by Delhi with a winter average of 170 ug/m3. The next seven places are occupied by neighboring NCR cities – Faridabad, Manesar, Baghpat, Noida, Gurugram, Meerut and Hapur. However, the CSE found that northern Indian cities recorded an average of 11 per cent lower PM2.5 over the last winter, but the improvement in the Delhi-NCR sub-region was just eight per cent. “Delhi-NCR also saw a marginal increase in average 24-hour pollution. There was a significant increase in peak pollution from baseline between cities in south (24 per cent) and central Indian cities (7 per cent), despite overall pollution. Average decline,” it said. In the northern region, Srinagar was found to be the cleanest city with relatively low winter averages, with Palwal in Haryana, Bathinda in Punjab and Alwar in Rajasthan. 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 the south, Kalaburagi in Karnataka and Hyderabad in Telangana were found to be the most polluted cities. The most polluted city in the Northeast region was Guwahati in Assam, where the winter average PM2.5 was 81 ug/m3. The analysis was 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 a specific region. It is now a widespread national problem that requires immediate and deliberate action at the national level. CSE’s executive director (research and advocacy) Anumita Roychowdhury said, “There is a need for quick reforms and action in key areas of pollution – vehicles, industries, power plants and waste management – to bend the annual air pollution curve and daily spikes. ” He said that while regions are struggling to meet national ambient air quality standards, winter conditions are adding to the problem. “Even though the epidemic situation has arrested the overall trend in most regions, there is a mixed trend. Despite having relatively low annual average pollution levels, peak pollution may increase during winter. It is characterized by cold and calm winters. Indicates the impact of the situation. And also the regional impact,” Ms. Roychowdhury said. Avikal Somvanshi, Program Manager, Urban Data Analytics Lab, CSE, said that with the expansion of air quality monitoring systems, the availability of real-time air quality data has improved in many regions, making it possible to assess regional differences and uniqueness. regional trends. CSE said that this air quality tracker initiative has helped in benchmarking winter air quality for peer-to-peer comparison within each region and inter-regional differences. The analysis is based on publicly available granular real-time data (average of 15 minutes) from the Central Control Room for Air Quality Management, the official online portal of the Central Pollution Control Board (CPCB). The data is drawn from 326 official stations under the Continuous Ambient Air Quality Monitoring System (CAAQMS) spread over 161 cities in 26 states and union territories.

Delhi Second-Most Polluted North Indian City.

Ghaziabad was the most polluted city among 60 north Indian cities last winter, followed by Delhi, according to a latest air quality analysis. According to the “All India Winter Air Quality Analysis” carried out by the Centre for Science and Environment (CSE), particulate pollution spiked and stayed elevated with varying intensity across all regions during the winter of 2021-22 (from October 15 to February 28). The analysis contains a detailed assessment of all the regions — north, south, east, west, central and northeast. It said the most polluted city in the northern region was Ghaziabad with a particulate matter 2.5 (PM2.5) average of 178 microgram per cubic metre (μg/m3), followed by Delhi that had a winter average of 170 ug/m3. The next seven spots are all occupied by neighbouring NCR cities — Faridabad, Manesar, Baghpat, Noida, Gurugram, Meerut and Hapur, it said.

Ghaziabad was probably the most polluted metropolis amongst 60 north Indian cities final winter, adopted by Delhi, based on a contemporary air high quality evaluation. Based on the “All India Winter Air High quality Evaluation” carried out by the Centre for Science and Surroundings (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 comprises an in depth evaluation of all of the areas — north, south, east, west, central and northeast. It mentioned probably 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 following 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.

Winter Pollution Levels in Most Parts of India Headed North, Small Towns Too Turning Toxic: CSE

mog episodes showed a record spike in several regions across the country this winter, said the Centre for Science and Environment (CSE) in its latest all-India winter air quality analysis, raising alarm over the deepening air pollution crisis. Though the air quality was 12 per cent cleaner this winter compared to the previous year based on an average of 136 cities that had valid daily PM2.5 concentration data, the peak pollution levels were “alarmingly high”, especially in the northern and eastern plains, the report highlighted. In terms of peak 24-hour PM 2.5 levels, north Indian cities showed the highest daily pollution, surpassing even the 2020-21 magnitude. In the northern region, Delhi-NCR remained the most-polluted sub-region with its worst days being almost five times worse than average. Delhi, Ghaziabad, Faridabad, and Manesar found their place among the top 10 most polluted cities, with Ghaziabad as the worst performer. Smaller cities turning into pollution hotspots Siwan in Bihar topped the list of most-polluted cities in India this winter with a seasonal average of 187 ug/m3. As many as 13 cities of Bihar featured in the top 25 cities with the highest pollution levels in winter. Delhi-NCR had 11 cities in the list, and Hisar in Haryana was the only city in the top 25 outside the sub-regions of Bihar and NCR. Advertisement “It is important to note that megacities 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,” said Avikal Somvanshi, programme manager, Urban Data Analytics Lab, CSE, highlighting that apart from the respective clean air action plans, cities will have to scale up their efforts to control pollution from all sources across the urban and rural landscape. The analysis is based on the real-time (every 15 minutes) data recorded by the Central Pollution Control Board (CPCB) from 326 official stations spread across 161 cities in 26 states and union territories for the winter period starting October 15, 2021, to February 28, 2022. Ghaziabad, Delhi show worst air quality in the north Out of the total 60 cities analysed in the northern states including Punjab, Haryana, Chandigarh, Delhi-NCR, Rajasthan and Uttar Pradesh, Ghaziabad was the worst-polluted, followed by Delhi. The next eight spots were all occupied by neighbouring NCR cities: Faridabad, Manesar, Bagpat, Noida, Gurugram, Meerut, and Hapur. Hisar was the most polluted city in the north outside of NCR.

However, the spikes were relatively milder. Within the east, the Bihar sub-region remained the most polluted, with six towns from the state featuring in the top 10 most-polluted cities this winter. Out of the total 28 monitoring stations spread across cities in Bihar, West Bengal, Jharkhand and Odisha, Siwan in Bihar emerged as the most-polluted, along with Durgapur in West Bengal. Patna and Kolkata were other cities that fared poorly in air quality. The people of Brajrajnagar in Odisha and Siliguri in West Bengal took a sigh of relief with both cities recording the lowest winter average in the region. “Clearly, the winter pollution challenge is not limited to one specific region; it is now a widespread national problem that requires urgent and deliberate action at a nationwide scale. Even though the pandemic conditions have arrested the overall trend in most regions, there is still a mixed trend,” said Anumita Roychowdhury, executive director, research and advocacy, CSE. “There is a need for 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.” Advertisement Cleaner air in southern India According to the CSE, the southern region recorded the lowest regional PM2.5 average this winter but it also registered an almost 24 per cent increase in regional average peak pollution compared to the previous winter. The region includes 35 cities spread across Andhra Pradesh, Karnataka, Kerala, Puducherry, Tamil Nadu and Telangana. Industrial towns, Gummidipoondi in Tamil Nadu and Gadag in Karnataka, also appeared in the worst 10 cities for peak pollution (24-hr value). The most polluted cities in the region were Kalaburagi and Hyderabad. Western region Out of the total 15 cities spread across Gujarat and Maharashtra, Ankleshwar was found to be most-polluted, followed by Vapi and Kalyan. Aurangabad and Nandesari recorded the lowest winter average in the region, along with Chandrapur and Solapur. Central region The region included 17 cities spread across Madhya Pradesh and Chhattisgarh. The most-polluted city in the region was Singrauli followed by Katni, Jabalpur, and Bhopal. North-eastern region Out of the total six cities in the Northeast, Guwahati was found to be the most polluted in the region, followed by Agartala. Aizawl and Shillong recorded the lowest winter average in the region mostly because of geographical location and topography. Advertisement According to the CSE, the widely divergent trends in pollution levels across regions is strongly influenced by local geo-climatic conditions, meteorology and the intensity of pollution, but the overall emerging trend points towards a national air quality crisis.

Bihar, Delhi-NCR en tête des graphiques de pollution, crise majeure de la qualité de l’air: CSE

La pollution particulaire a augmenté et est restée élevée avec une intensité variable dans toutes les régions au cours de l’hiver 2021-22 (du 15 octobre au 28 février), la moyenne hivernale des PM2,5 de la région orientale étant plus de trois fois supérieure à la moyenne des villes du sud de l’Inde. et 22 % plus polluées que les villes du nord de l’Inde. Cette observation alarmante a été trouvée dans une analyse détaillée de la qualité de l’air hivernal dans toute l’Inde réalisée par le Centre pour la science et l’environnement (CSE) et publiée mercredi. Même si les moyennes régionales globales des niveaux de PM2,5 étaient inférieures à celles de l’hiver précédent dans la plupart des régions, les épisodes de smog hivernal ont enregistré de fortes pointes dans plusieurs régions. Le pic de pollution était alarmant et synchrone, malgré de grandes distances à l’intérieur des régions – en particulier dans les plaines du nord et de l’est, selon l’analyse. L’analyse a été effectuée pour l’initiative de suivi de la qualité de l’air en hiver 2021-22 du laboratoire d’analyse de données urbaines du CSE. “De toute évidence, le défi de la pollution hivernale ne se limite pas aux mégapoles ou à une région spécifique ; c’est maintenant un problème national répandu qui nécessite une action urgente et délibérée à l’échelle nationale. Cela nécessite des réformes et une action plus rapides dans les secteurs clés de la pollution – véhicules, industrie, centrales électriques et gestion des déchets pour faire fléchir la courbe annuelle de la pollution de l’air et les pics quotidiens “, a déclaré le directeur exécutif, Recherche et plaidoyer du CSE, dit Anumita Roychowdhury. “Comme la disponibilité des données en temps réel sur la qualité de l’air s’est améliorée dans plusieurs régions grâce à l’expansion des systèmes de surveillance de la qualité de l’air, il est devenu possible d’évaluer les différences régionales et les tendances régionales uniques. Cela peut aider à éclairer l’action régionale sur la qualité de l’air”, a déclaré le responsable du programme du CSE, Urban Data Analytics Lab, Avikal Somvanshi. Cette initiative de suivi de la qualité de l’air a aidé à évaluer la qualité de l’air en hiver pour la comparaison entre pairs dans chaque région et les différences interrégionales. L’analyse est basée sur des données granulaires en temps réel accessibles au public (moyennes sur 15 minutes) du portail en ligne officiel du Central Pollution Control Board Central Control Room for Air Quality Management. Les données sont capturées à partir de 326 stations officielles dans le cadre du système de surveillance continue de la qualité de l’air ambiant (CAAQMS) réparties dans 161 villes de 26 États et territoires de l’Union. Selon l’analyse, le profil régional de la pollution hivernale a montré que la région orientale est aussi polluée que Delhi-NCR. La moyenne hivernale de PM2,5 dans les plaines orientales qui comprennent également les 19 villes et villages nouvellement surveillés du Bihar, était la même que celle de Delhi-NCR. Six villes du Bihar figurent dans le top 10 des villes les plus polluées cet hiver, avec Siwan et Munger en tête. Dans les plaines du nord, Ghaziabad, Delhi, Faridabad et Manesar sont troisième, cinquième, septième et dixième de la liste. Même si la moyenne saisonnière dans les petites villes du Bihar rivalise avec les mégapoles de la RCN, leur pic de pollution pendant les épisodes de smog est comparativement plus doux, a-t-il déclaré. Les villes de la RCN ont connu les niveaux de PM2,5 quotidiens les plus sévères (moyenne sur 24 heures), Ghaziabad étant la plus touchée. Delhi, Noida, Faridabad, Greater Noida et Gurugram sont parmi les pires qui ont connu un pic de pollution (moyenne sur 24 heures) cet hiver. La moyenne hivernale de PM2,5 de la région orientale est plus de trois fois supérieure à la moyenne des villes du sud de l’Inde et 22 % plus polluée que les villes du nord de l’Inde. A l’est, la sous-région du Bihar est la plus polluée. Du point de vue du niveau maximal de PM2,5 sur 24 heures, les villes du nord de l’Inde ont enregistré en moyenne les niveaux de pollution quotidiens les plus élevés. Dans le nord, Delhi-NCR reste la sous-région la plus polluée, ses pires jours étant près de cinq fois supérieurs à la moyenne. Somvanshi a déclaré: “Il est important de noter que les mégapoles ne sont les plus polluées d’aucune des régions – ce sont les villes plus petites et à venir qui deviennent des points chauds de pollution. Cela est encore plus évident dans les données de pollution quotidienne de pointe hivernale. “

ns l’Haryana, Bathinda dans le Pendjab et Alwar dans le Rajasthan parmi les villes avec une moyenne hivernale relativement inférieure. Dans la région orientale, la ville la plus polluée était Siwan au Bihar tandis qu’à l’ouest, c’était Ankleshwar au Gujarat. Dans la région centrale, Singrauli au Madhya Pradesh était la ville la plus polluée tandis qu’au sud, Kalaburgi au Karnataka et Hyderabad au Telangana étaient les villes les plus polluées. La ville la plus polluée de la région du nord-est était Guwahati dans l’Assam avec une moyenne hivernale de PM2,5 de 81 ug/m3. L’analyse a été effectuée pour l’initiative de suivi de la qualité de l’air en hiver 2021-22 du Laboratoire d’analyse des données urbaines du CSE. ”De toute évidence, le défi de la pollution hivernale ne se limite pas aux mégapoles ou à une région spécifique. Il s’agit désormais d’un problème national répandu qui nécessite une action urgente et délibérée à l’échelle nationale. “Cela nécessite des réformes et des actions plus rapides dans les secteurs clés de la pollution – véhicules, industrie, centrales électriques et gestion des déchets – pour faire fléchir la courbe annuelle de la pollution atmosphérique et les pics quotidiens”, a déclaré Anumita Roychowdhury, directrice exécutive, recherche et plaidoyer, CST. Elle a déclaré que tandis que les régions se battent pour respecter les normes nationales de qualité de l’air ambiant, les conditions hivernales aggravent encore le problème. ” Même si les conditions pandémiques ont arrêté la tendance générale dans la plupart des régions, il y a toujours une tendance mitigée. Malgré des niveaux de pollution moyens annuels relativement plus faibles, le pic de pollution en hiver peut atteindre des sommets. Cela indique l’influence des conditions hivernales fraîches et calmes ainsi que l’influence régionale”, a déclaré Roychowdhury. Avikal Somvanshi, responsable de programme, Urban Data Analytics Lab, CSE, a déclaré que la disponibilité des données en temps réel sur la qualité de l’air s’est améliorée dans plusieurs régions avec l’expansion des systèmes de surveillance de la qualité de l’air, il est devenu possible d’évaluer les différences régionales et l’unique tendances régionales. Cette initiative de suivi de la qualité de l’air a permis de comparer la qualité de l’air en hiver pour une comparaison entre pairs dans chaque région et les différences interrégionales, a déclaré le CSE. L’analyse est basée sur des données granulaires en temps réel accessibles au public (moyennes sur 15 minutes) du portail en ligne officiel du Central Pollution Control Board (CPCB), Central Control Room for Air Quality Management.

Ghaziabad et Delhi sont les villes les plus polluées du nord de l’Inde en hiver: CSE

Ghaziabad était la ville la plus polluée parmi 60 villes du nord de l’Inde l’hiver dernier, suivie de Delhi, selon une dernière analyse de la qualité de l’air. Selon l’analyse de la qualité de l’air en hiver de toute l’Inde réalisée par le Centre pour la science et l’environnement (CSE), la pollution particulaire a augmenté et est restée élevée avec une intensité variable dans toutes les régions au cours de l’hiver 2021-22 (du 15 octobre au 28 février). L’analyse contient une évaluation détaillée de toutes les régions — nord, sud, est, ouest, centre et nord-est. Il a indiqué que la ville la plus polluée de la région nord était Ghaziabad avec une moyenne de particules 2,5 (PM2,5) de 178 microgrammes par mètre cube (μg/m3), suivie de Delhi qui avait une moyenne hivernale de 170 ug/m3. Les sept places suivantes sont toutes occupées par des villes voisines de la RCN – Faridabad, Manesar, Baghpat, Noida, Gurugram, Meerut et Hapur, a-t-il précisé. Le CSE, cependant, a observé que les villes du nord de l’Inde ont, en moyenne, enregistré un niveau de PM2,5 inférieur de 11 % l’hiver dernier, mais l’amélioration dans la sous-région de Delhi-RCN n’était que d’environ 8 %. ”Delhi-NCR a également vu une augmentation marginale du pic moyen de pollution sur 24 heures. Le pic de pollution a augmenté de manière significative par rapport au niveau de référence entre les villes du sud (24%) et les villes du centre de l’Inde (7%), malgré la baisse globale de la moyenne hivernale », a-t-il déclaré. Dans la région nord, Srinagar s’est avérée être la ville la plus propre avec Palwal dans l’Haryana, Bathinda dans le Pendjab et Alwar dans le Rajasthan parmi les villes avec une moyenne hivernale relativement inférieure. Dans la région orientale, la ville la plus polluée était Siwan au Bihar tandis qu’à l’ouest, c’était Ankleshwar au Gujarat. Dans la région centrale, Singrauli au Madhya Pradesh était la ville la plus polluée tandis qu’au sud, Kalaburgi au Karnataka et Hyderabad au Telangana étaient les villes les plus polluées.

Gurugram: Steps kicked off to eliminate single-use plastic by July 1

GURUGRAM: A detailed action plan to eliminate single-use plastics (SUPs) in the city and strictly implement the Plastic Waste Management Rules, 2016, will be mapped by officials with the Gurugram administration, the Haryana State Pollution Control Board (HSPCB) and the Municipal Corporation of Gurgaon (MCG) on Tuesday. HSPCB chairman P Raghavendra Rao this month, on March 2, directed all 22 Haryana districts to take steps to eliminate single-use plastics by July 1. On Tuesday, all authorities responsible for managing plastic waste in Gurugram will submit their action taken reports to the deputy commissioner; the mapping of the city-wide plan will follow. According to officials, single-use plastic products produced and designed to be thrown away after being used only once are convenient to use. However, their damage during production and distribution and litter are threats to the environment and human health. The plastic items that face prohibition include earbuds, flags, candy and ice-cream sticks, decorative thermocol, PVC banners less than 100 microns thick, cups, cutlery, etc. According to the Centre for Science and Environment, plastic packaging contributes to nearly 60% of the plastic waste generated. Explaining the move, officials said that the SUPs contaminate soil and water, chokes waterways and leads to natural disasters. They block sewage systems, provide breeding grounds for mosquitoes, and release toxic chemicals and emissions when burned. “Our teams have been spreading awareness about the ill effects of single-use plastics. We will submit our action taken report with the deputy commissioner for further course of action,” said Kuldeep Singh, regional officer (North), HSPCB, Gurgaon.

Municipal workers burn dry leaves along Ballygunge road despite ban since 2016

On Monday morning, residents in the area woke up to a pungent smell Many residents of Ballygunge Circular Road woke up on Monday to a strong smell caused by burning of fallen leaves by waste collectors of the Kolkata Municipal Corporation (KMC) along the thoroughfare. The National Green Tribunal had in 2016 banned open burning of waste. The tribunal had said a fine of Rs 5,000 would be imposed for burning waste in the open and a fine of Rs 25,000 for bulk burning of waste in the open. The KMC’s Solid Waste Management Rules (published in 2020), too, has provisions for imposition of fines for burning waste in the open. Despite the tribunal’s order and the KMC rules, waste collectors of the civic body and others are often seen burning waste in the open. The practice is more rampant during winter and spring, when trees shed leaves. Debabrata Majumdar, mayoral council member in charge of the KMC’s solid waste management department, said he would probe reports of open burning of leaves. “We have never received any complaint of open waste burning from this area. We have clearly told our waste collectors to not burn waste in the open. This is usually done by local people. I will try to find out what happened there,” he said. In December, The Telegraph reported that a mound of dry leaves and other solid waste were put on fire on the Maidan. Waste collectors are prone to burning a part of the waste to save on trips to compactor stations. Ashes produced by the burning fly around and pollute the air. On Monday morning, Ballygunge Circular Road residents were surprised to smell something burning. As they looked out, the residents discovered that fallen leaves had been set on fire. “It happens in winter, too, but the fumes usually do not enter our houses as the windows are shut. Since now we keep the windows open, the acrid fumes hit us,” said a resident of an apartment on Ballygunge Circular Road. “I woke up choking the other night,” said Amit Das, a guard at a housing complex on Ballygunge Circular Road. When asked why he didn’t stop those who were burning leaves, Das said: “They do not listen to us. It is extra work for them to pick the leaves up and throw them into a vat. Setting them on fire is far easier.” A municipal worker who was found burning leaves said: “Itna patte kaise uthaye (How can I pick up so many leaves).” Sources said several burning piles were spotted on Ballygunge Circular Road and at Ballygunge Phanri on Sunday night. Anumita Roy Chowdhury, an air quality management expert, said uncontrolled burning of open waste leads to uncontrolled emissions. “There is a sudden and significant rise in local pollution. This can be stopped if the KMC creates enough composting infrastructure,” she said.
