PM10 के स्तर में कटौती के मामले में वाराणसी शीर्ष पर, सरकार का कहना है; सीएसई ने शहर-आधारित दृष्टिकोण को ध्वजांकित किया

नई दिल्ली: स्वच्छ हवा पर एक राष्ट्रीय कार्यक्रम के तहत पहचाने गए 132 प्रदूषित शहरों में से 95 ने 2017 की तुलना में 2021-22 में पार्टिकुलेट मैटर (पीएम10) की सांद्रता को कम करके वायु गुणवत्ता में सुधार दिखाया है, जिसमें वाराणसी में सबसे अधिक 53% की कमी दर्ज की गई है। इस अवधि के दौरान खतरनाक प्रदूषकों का स्तर, सरकार ने अपने विश्लेषण में दावा किया, यहां तक ​​कि ग्रीन थिंकटैंक सेंटर फॉर साइंस एंड एनवायरनमेंट (सीएसई) ने इस तरह के शहर-आधारित दृष्टिकोण की सीमाओं को चिह्नित किया है। विश्लेषण में पाया गया कि चेन्नई सहित 95 शहरों में से 20, मदुरैनासिक और चित्तूर, यहां तक ​​कि राष्ट्रीय परिवेशी वायु गुणवत्ता मानकों (NAAQS) के अनुरूप हैं, जो PM10 की स्वीकार्य वार्षिक औसत सीमा 60 माइक्रोग्राम प्रति घन मीटर (μg/m3) रखते हैं। वायु योग्यता (1) हालांकि, पर्यावरण मंत्रालय द्वारा किए गए विश्लेषण में अन्य सूक्ष्म और अधिक खतरनाक पार्टिकुलेट मैटर, पीएम2. 5, एकरूपता के लिए सभी 132 शहरों में केवल PM10 की निगरानी की जाती है। नीचे राष्ट्रीय स्वच्छ वायु कार्यक्रम (एनसीएपी), मंत्रालय ने देश भर में 2017 के स्तर से 2024 तक पार्टिकुलेट मैटर एकाग्रता में 20-30% की कमी का लक्ष्य रखा है। केवल 43 एनसीएपी शहरों में पर्याप्त PM2. 2019-2021 की अवधि के लिए 5 डेटा। वाराणसी के अलावा, जिसने सबसे बड़ा सुधार दर्ज किया, उस अवधि के दौरान पीएम 10 के स्तर में सुधार दिखाने वाले अन्य शहरों में दिल्ली, मुंबई, कोलकाता, बेंगलुरु, हैदराबाद, नोएडा, गाजियाबाद, लखनऊ, कानपुर, आगरा, पुणे, नागपुर और चंडीगढ़ शामिल हैं। हालाँकि, अधिकांश शहरों में PM10 की सांद्रता लक्ष्य और साथ ही NAAQS सीमा में सुधार के बावजूद बहुत अधिक स्तर पर आंकी गई है। उदाहरण के लिए, दिल्ली में, PM10 का स्तर 2017 में 241μg/m3 से घटकर 2021-22 में 196 ug/m3 हो गया – 18% की कमी, लेकिन यह 60 ug/m3 की स्वीकार्य सीमा के तीन गुना से अधिक है। मुंबई में, PM10 का स्तर 2017 में 151µg/m3 से घटकर 2021-22 में 106 ug/m3 हो गया। कोलकाता में, यह 2017 में 119 माइक्रोग्राम प्रति घन मीटर से घटकर 2021-22 में 105 माइक्रोग्राम प्रति घन मीटर हो गया। सीएसई ने चेतावनी दी कि मौजूदा स्वच्छ वायु कार्य योजनाएँ जो सफाई कार्य के लिए शहरों के चारों ओर कठिन सीमाएँ खींचती हैं, बड़ी कक्षा में प्रमुख प्रदूषण स्रोतों को संबोधित करने में विफल हो रही हैं। “प्रदूषण के क्षेत्रीय प्रभाव का विज्ञान भारत में आकार लेने लगा है। एनसीएपी ने क्षेत्रीय वायु गुणवत्ता प्रबंधन के सिद्धांत को अपने साथ ले लिया है। लेकिन गठबंधन कार्रवाई के लिए बहु-क्षेत्राधिकार प्रबंधन को सक्षम करने और क्षेत्रीय वायु गुणवत्ता में सुधार के लिए राज्य सरकारों की अपविंड और डाउनविंड जिम्मेदारियों को स्थापित करने के लिए कोई नियामक ढांचा नहीं है,” सीएसई के कार्यकारी निदेशक अनुमिता रॉयचौधरी ने कहा।

Varanasi tops cities in cutting PM10 levels, says govt; CSE flags city-based approach

NEW DELHI: Ninety-five out of 132 polluted cities identified under a national programme on clean air have shown improvement in air quality by reducing particulate matter (PM10) concentration in 2021-22 compared to 2017, with Varanasi recording the highest 53% reduction in the level of hazardous pollutant during the period, claimed the government in its analysis, even as the green thinktank Centre for Science and Environment (CSE) has flagged limitations of such city-based approach. The analysis found that 20 of the 95 cities, including Chennai, Madurai, Nashik and Chittur, have even conformed to the National Ambient Air Quality Standards (NAAQS) that put acceptable annual average limit of PM10 at 60 micrograms per cubic meter (µg/m3). air qua (1) Congratulations! You have successfully cast your vote The analysis, done by the environment ministry, has, however, not factored in the other fine and more hazardous particulate matter, PM2. 5, for the sake of uniformity as only PM10 is monitored in all 132 cities. Under the national clean air programme (NCAP), the ministry has set targets of 20-30% reduction in particulate matter concentration by 2024 from 2017 levels across the country. Only 43 NCAP cities have adequate PM2. 5 data for the period 2019-2021. Besides Varanasi that reported the biggest improvement, the other cities thathave shown improvement in PM10 levels during that period include Delhi, Mumbai, Kolkata, Bengaluru, Hyderabad, Noida, Ghaziabad, Lucknow, Kanpur, Agra, Pune, Nagpur and Chandigarh. The PM10 concentration in most of the cities, however, continues to be figured at much higher levels than the targets as well as the NAAQS limit despite showing improvement. For example, in Delhi, the PM10 level reduced from 241µg/m3 in 2017 to 196 µg/m3 in 2021-22 — a reduction of 18%, but it is more than three times of the acceptable limit of 60 µg/m3. In Mumbai, the PM10 level reduced from 151µg/m3 in 2017 to 106 µg/m3 in 2021-22. In Kolkata, it reduced from 119 µg/m3 in 2017to 105 µg/m3 in 2021-22. The CSE warned that the existing clean air action plans that draw hard boundaries around cities for the clean-up job are failing to address the major pollution sources in the larger orbit. “The science of regional influence of pollution has begun to take shape in India. The NCAP has taken on board the principle of regional air quality management. But there is no regulatory framework to enable multi-jurisdiction management for aligned action and to establish the upwind and downwind responsibilities of state governments to improve regional air quality,” said Anumita Roychowdhury, executive director, CSE.

Ghaziabad News: What is the problem of Ghaziabad, why people got upset

There is bad news for Ghaziabad. This district has become one of the most polluted cities in North India. When the Center for Science and Environment (CSE) studied pollution on the basis of PM2.5 for the year 2021, this report of Ghaziabad came out. This study has revealed that incomplete construction and traffic pollution of the by-pass road has come to light The biggest reason for Due to non -construction of 20 percent of the bypass road, the local residents are facing the problem of heavy jam between Rajnagar Extension and Meerut Road. Significantly, the speed of traffic here is also slow. Due to this, pollution levels in this area are high. Local RWA is in touch with local authorities, but the progress to complete this small part of the road is very slow. The GDA had already acquired this land. He has also constructed 80% of the left-pass road. Under the ADM (LA) Land Acquisition Rehabilitation and Rehabilitation Act 2013, the land is working on land acquisition according to section 3 (1), but at a very slow speed. Due to this, people here are having problems with traffic and air pollution.

But, it dissolves with breath and gives great damage. People of the nearby society told News 18 that the biggest problem here is pollution, traffic and garbage here. The soil of the work which is not completed will also be found here. Because of this, people are having a big problem. People said that we have gone to GDA many times. Till 20 percent of it is constructed, there will be a similar problem. It should be resolved as soon as possible.

Varanasi tops cities in cutting PM10 levels, says govt; CSE flags city-based approach

Ninety-five of the 132 polluted cities identified in the national clean air program have shown improvements in air quality by reducing particulate matter (PM10) concentrations in period 2021-22 compared to 2017, during which Varanasi recorded the highest 53% reduction in hazardous pollution levels during this period, the government stated in its analysis, even if the Center Green thinking about Science and Environment (CSE) highlighted the limitations of such a city-based approach. The analysis shows that 20 out of 95 cities, including Chennai, MaduraiNashik and Chittur, even complied with the National Ambient Air Quality Standard (NAAQS) setting an acceptable annual average limit for PM10 of 60 micrograms per cubic meter (µg/m3). air pass (1) However, the analysis carried out by the Ministry of Environment did not take into account the finer and more dangerous particulate matter, PM2. 5, for the sake of uniformity as only PM10 is monitored in all 132 cities. Under national clean air program (NCAP), the Department has set a target of a 20-30% reduction in particulate matter concentrations by 2024 from 2017 levels nationally. Only 43 NCAP the city has enough PM2. 5 data for the period 2019-2021. Besides Varanasi which reported the greatest improvement, other cities that have shown improvement in PM10 levels during that period include Delhi, Mumbai, Kolkata, Bengaluru, Hyderabad, Noida, Ghaziabad, Lucknow, Kanpur, Agra , Pune, Nagpur and Chandigarh. However, PM10 concentrations in most cities continue to be calculated to be much higher than the NAAQS target and limit despite showing improvement. In Delhi, for example, PM10 levels fell from 241µg/m3 in 2017 to 196 µg/m3 in 2021-22 – an 18% decrease, but it is more than three times the acceptable limit of 60 µg/m3. In Mumbai, PM10 levels drop from 151µg/m3 in 2017 to 106 µg/m3 in 2021-22. In Kolkata, it drops from 119 µg/m3 in 2017 to 105 µg/m3 in 2021-22. The CSE warns that existing clean air action plans that draw tough boundaries around cities for cleanup will not address major sources of pollution in a larger orbit. “The science of the effects of pollution in the region has begun to take shape in India. NCAP has adopted regional air quality management principles. But there is no regulatory framework that allows multi-jurisdictional management to take appropriate action and establish forward and backward accountability by state governments to improve air quality in the region,” said Anumita Roychowdhury, chief executive officer, CSE said.

Ninety-five out of 132 polluted cities identified under a national programme on clean air have shown improvement in air quality by reducing particulate matter (PM10) concentration in 2021-22 compared to 2017, with Varanasi recording the highest 53% reduction in the level of hazardous pollutant during the period, claimed the government in its analysis, even as the green thinktank Centre for Science and Environment (CSE) has flagged limitations of such city-based approach.

NEW DELHI: Ninety-five out of 132 polluted cities identified under a national programme on clean air have shown improvement in air quality by reducing particulate matter (PM10) concentration in 2021-22 compared to 2017, with Varanasi recording the highest 53% reduction in the level of hazardous pollutant during the period, claimed the government in its analysis, even as the green thinktank Centre for Science and Environment (CSE) has flagged limitations of such city-based approach. The analysis found that 20 of the 95 cities, including Chennai, Madurai, Nashik and Chittur, have even conformed to the National Ambient Air Quality Standards (NAAQS) that put acceptable annual average limit of PM10 at 60 micrograms per cubic meter (µg/m3). 94139700 The analysis, done by the environment ministry, has, however, not factored in the other fine and more hazardous particulate matter, PM2. 5, for the sake of uniformity as only PM10 is monitored in all 132 cities. Under the national clean air programme (NCAP), the ministry has set targets of 20-30% reduction in particulate matter concentration by 2024 from 2017 levels across the country. Only 43 NCAP cities have adequate PM2. 5 data for the period 2019-2021. Besides Varanasi that reported the biggest improvement, the other cities thathave shown improvement in PM10 levels during that period include Delhi, Mumbai, Kolkata, Bengaluru, Hyderabad, Noida, Ghaziabad, Lucknow, Kanpur, Agra, Pune, Nagpur and Chandigarh. The PM10 concentration in most of the cities, however, continues to be figured at much higher levels than the targets as well as the NAAQS limit despite showing improvement. For example, in Delhi, the PM10 level reduced from 241µg/m3 in 2017 to 196 µg/m3 in 2021-22 — a reduction of 18%, but it is more than three times of the acceptable limit of 60 µg/m3. In Mumbai, the PM10 level reduced from 151µg/m3 in 2017 to 106 µg/m3 in 2021-22. In Kolkata, it reduced from 119 µg/m3 in 2017to 105 µg/m3 in 2021-22. The CSE warned that the existing clean air action plans that draw hard boundaries around cities for the clean-up job are failing to address the major pollution sources in the larger orbit. “The science of regional influence of pollution has begun to take shape in India. The NCAP has taken on board the principle of regional air quality management. But there is no regulatory framework to enable multi-jurisdiction management for aligned action and to establish the upwind and downwind responsibilities of state governments to improve regional air quality,” said Anumita Roychowdhury, executive director, CSE.
