Delhi's air quality remains under ‘poor’ category on Saturday; AQI at 262

The air quality of Delhi on Saturday remained under the ‘poor’ category as per the System of Air Quality and Weather Forecasting And Research (SAFAR)-India. The Air Quality Index (AQI) stood at 262 on Saturday morning. With the Diwali festival around, the city's air quality has continued to deteriorate. Every year, Delhi's pollution level spikes up from October and lasts till the end of fall due to various reasons such as the burning of stubble, smog, etc. Under the campaign, first launched on October 16, 2020, to cut down vehicular pollution in the national capital, drivers are encouraged to switch off their vehicles while waiting for the traffic light to turn green. Data from the Petroleum Conservation Research Association (PCRA) shows that if people switch off engines at traffic signals, pollution can be cut down by 13-20%. According to government estimates, the transport sector accounts for 28% of the PM2.5 emissions in Delhi. The vehicular contribution also makes up 80% of nitrogen oxides and carbon monoxide in Delhi's air. Separately, in an analysis by the Centre for Science and Environment (CSE), Delhi's PM2.5 pollution during July-September remained lowest in 5 years.

Rains Helped, as Will an Early Diwali, But Delhi Still Needs to Brace for Poor Air Quality

Extra rainy days in October improved air quality in Delhi but stubble burning and Diwali could undo this soon. The air quality of the city is likely to remain 'very poor' or 'poor' for the next six days. New Delhi: Though extra rainy days in the first half of October lowered air pollution in Delhi, the national capital will still need to brace for poor air quality as Diwali approaches and stubble burning picks up in Delhi, Punjab and Haryana.

Air quality in Delhi is likely to remain in the “Very Poor” to “Poor” category, as per the government’s air quality early warning system, till October 27. Delhi’s dipping air quality Delhi, the National Capital Region (NCR) and surrounding areas witness high levels of air pollution during the winter months, starting October. Fine particulate matter (PM2.5, consisting of particles less than 2.5 mm in diameter, produced from sources including fossil fuel combustion) from vehicular traffic, construction activities and emissions from thermal power plants are some of the causes for the high pollution levels in the city. Local weather conditions can also play a role in air quality levels. The lack of winds, for example, can concentrate pollutants in the area and spike air pollution levels.

Delhi's Air Quality Remains 'Poor' One Day Before Diwali, Plan Floated To Tackle Stubble Burning Woes

Air quality in the national capital on Saturday remained in the poor category after it worsened at the 24-hour average AQI of 262 the previous day. The weather office has predicted mainly clear skies on Saturday. The Central Pollution Control Board's 24-hour average AQI bulletin on Friday stated that the index value was in the 'poor' category at 268. On Thursday, the index value was recorded at 228. As the air quality deteriorates in Delhi every year with winter approaching, factors of stubble burning and cracker bursting on Diwali are widely discussed. Unfavourable meteorological factors such as low temperatures and wind speed, which do not allow the dispersion of pollutants, also contribute to the worsening of air quality in Delhi-NCR in October every year. Delhi's Plan To Reduce Pollution Due To Crackers & Stubble Burning Delhi Environment Minister Gopal Rai on Saturday said that the Delhi Government has initiated a 15-point Winter Action Plan in order to reduce the dust pollution caused by stubble burning in the National Capital. "A dust campaign is being run to stop the burning of stubble inside Delhi. Bio-de-composer is being used to stop the burning of firecrackers on Diwali in the same episode in Delhi," he said, as quoted by news agency ANI. The Delhi Environment Minister further mentioned that as many as 51,000 diyas have been lit to give only one message that there can be such a beautiful Diwali too. Notably, the sale or storage of firecrackers in the national capital can be punished with a fine of Rs 5,000 and/or imprisonment for three years. Diwali Cracker Ban The ban on firecrackers in the national capital continues as the Supreme Court on Thursday refused an urgent hearing of a plea seeking the removal of prohibition, saying "let the people of Delhi breathe clean air". The plea was filed by BJP MP Manoj Tiwari, reported news agency PTI. A bench of Justices M R Shah and M M Sundresh refused to list the plea challenging the direction issued by the Delhi Pollution Control Committee (DPCC) on September 14 for a complete ban on manufacturing, storage, sale, and bursting of all kinds of firecrackers till January 1, 2023, in Delhi. The bench told the counsel appearing for the BJP MP that instead of firecrackers, people should spend their money on sweets. "Let the people of Delhi breathe clean air. People should not spend money on firecrackers instead they should eat sweets," the bench said, as quoted by PTI. It mentioned that plea will be coming up for hearing along with the main matter pending before the court. Earlier in the day, noting the pendency of issues related to firecrackers before the Supreme Court, the Delhi High Court also refused to entertain a petition challenging the ban on sale and use of all kinds of firecrackers in the national capital. The top court had last year clarified there is no blanket ban on the use of firecrackers and only those fireworks which contain barium salts are prohibited. Stubble Burning Continues Punjab Agriculture Minister Kuldeep Singh Dhaliwal said that 2,625 incidents of stubble burning were reported so far. "By this time in 2020, there were 7,115 stubble-burning incidents and in 2022, up till date, there have been only 2,625 stubble-burning incidents, which is very low in comparison. Incidents are decreasing day by day. We're creating awareness among farmers," Dhaliwal said, as quoted by ANI. Last week he said, "We are constantly trying that the stubble should not be burnt at least in Punjab. All the officials have been told that there will be no FIR against the farmers. But we believe that the farmers will avoid stubble burning. We are also working in the direction to ensure stubble becomes an additional source of income for the farmers in the coming days." As for Haryana, 134 cases of stubble burning were registered in Kaithal - the highest in the state. "A total fine of Rs 3.35 Lakhs was imposed on the farmers. FIR will now be registered against erring farmers," Sangeeta Tetarwal, Deputy Commissioner, Kaithal said on Friday, as quoted by ANI. Visuals of stubble burning have continued to surface even as Punjab Chief Minister Bhagwant Mann held meetings with farmers to assure them of his government's efforts towards paddy straw management

Not stubble burning, local factors to be blamed for Delhi's pollution, shows govt data

Farm fires or stubble burning is contributing 3-4% to Delhi's pollution, but the situation may take a turn for the worse after Diwali, shows government data. In Short As per Safar, fire counts/emissions over northwest region are gradually increasing. The atmospheric wind right now is facilitating the contribution of local emissions. Burning activities have picked up in Punjab, Haryana and Delhi. By Milan Sharma: Farm fires or stubble burning is contributing 3-4% to Delhi's pollution, but the situation may take a turn for the worse after Diwali, shows government data. According to System of Air Quality and Weather Forecasting And Research (SAFAR), the central government’s environment data monitoring platform, the smoke emanating from farm fires contributed about 3% to Delhi’s PM2.5 level on October 17. Between October 20 and 21, the percentage hovered between 2-3%. advertisement The Safar website said, “Fire counts/emissions over northwest region are gradually increasing (< 500) but its impact on Delhi’s air quality is meagre (< 3%) due to unfavorable transport level wind flow.” Also Read: Stubble burning: Will Delhi breathe easy this winter? “The contribution of stubble burning to Delhi’s pollution is less, it is only 3-4% right now,” said Vivek Chattopadhyay, senior programme manager, Clean Air Programme, Centre for Science and Environment, New Delhi. “It is being said it may increase after October 22, but the situation of the atmospheric wind right now is such that local emissions are contributing more to Delhi’s pollution. Transport sector is contributing around 50% to Delhi’s pollution, traffic volume has increased due to festivities. Vehicles pollute 2% more than they do at a normal speed when in traffic. In fact, there are other sources of burning - industrial, biomass and garbage set on fire," said Chattopadhyay. CHECK THESE OUT Arrey aunty chhodo!

This is happening because burning activities have picked up in Punjab-Haryana-Delhi. The total radiative power of these fires in Punjab-Haryana-Delhi breached 2,000 watt on October 16,” said a release issued by Centre for Science for Science and Environment on winter pollution and its key findings.

However, experts point out that this is less than half of the value recorded in 2020 and 2021 for the same period. Last year, the instances of farm stubble fires were the highest in the last seven years. The October-November period of 2021 saw a 10% jump in fire count by Moderate Resolution Imaging Spectroradiometer (MODIS) and 5% increase by Visible Infrared Imaging Radiometer Suite (VIIRS) compared to 2020 October-November. Similarly, the total fire radiative power from these fires were 13% and 7% higher compared to the 2020 fires as observed by MODIS and VIIRS respectively. In fact, there is a consistent increase in instances and intensity of farm fires since 2019, said the CSE report.

दिवाली के समय पराली जलाने से बढ़ सकती है समस्या, वायु गुणवत्ता और बदतर हो सकती है : सीएसई

नयी दिल्ली: विज्ञान एवं पर्यावरण केंद्र (सीएसई) ने गुरुवार को कहा कि इस साल दिवाली ऐसे वक्त में मनायी जा रही है जब पहले की अपेक्षा ज्यादा ठंड नहीं है लेकिन दिल्ली के पड़ोसी राज्यों में पराली जलाने से वायु प्रदूषण की समस्या बढ़ सकती है. दिल्ली-राष्ट्रीय राजधानी क्षेत्र (एनसीआर) में वायु गुणवत्ता प्रतिकूल मौसम विज्ञान संबंधी कारकों जैसे कम तापमान और हवा की गति के कारण अक्टूबर में बिगड़नी शुरू हुई थी जिससे प्रदूषकों का छितराव नहीं हुआ. पटाखों से होने वाला उत्सर्जन तथा पड़ोसी राज्यों में पराली जलाने से वायु गुणवत्ता और बदतर होगी. सीएसई ने कहा कि इस साल दिवाली पहले ही आ रही है, ‘‘जिसका मतलब है कि गर्म मौसम और हवा की स्थितियां प्रदूषण को कम करने में मदद करेगी जो दिवाली की रात के समारोहों का हिस्सा बन गया है.

Delhi's AQI to Cross 300? 'Poor' Air Leads to Pre-Diwali Smog; Docs Foresee Rise in Lung Diseases

Delhi, which saw clean air during the preceding monsoon months this year, recorded poor air quality ahead of Diwali with the air quality index (AQI) falling to 262 on Friday. With the approaching winter, the air quality is further expected to dwindle as the Commission for Air Quality Management (CAQM) has predicted that the AQI of the national capital region may exceed 300-mark on Saturday. Visuals from India Gate on Saturday showed a blanket of smog engulfing the national capital as the overall AQI remained in the poor category. Delhi Environment Minister Gopal Rai also said that experts are of the view that pollution levels may increase in Delhi after Diwali if the wind direction changes. Delhi’s PM2.5 pollution average for the July-August-September quarter this year stood at 37 microgram per cubic metre, only marginally higher than the five-year low of 36 microgram per cubic metre recorded during 2020, according to Centre for Science and Environment (CSE). Pollution levels in the July-August-September quarter were preceded by one of the most polluted summers this year, unlike in 2020 when the trimester followed the cleanest ever summer (March-May) due to extraordinary conditions created because of hard pandemic lockdowns, the think tank said.

Delhi Air Pollution : বাতাসে বাড়ছে দূষণ, দিওয়ালির পর ফের দমবন্ধ পরিস্থিতির আশঙ্কায় দিল্লি

दिवाली से पहले ही दिल्ली में हवा हुई जहरीली, AQI गिरकर 'खराब' श्रेणी में पहुंचा

दिवाली से पहले ही दिल्ली की हवा जहरीली हो गई है. पंजाब में पराली जलाने की घटनाओं पर असरदार रोक नहीं लगने से पहले ही इस बात की आशंका जाहिर की जा रही थी कि आनेवाले दिनों में दिल्ली गैस चैंबर में बदल सकती है. शनिवार को दिल्ली की वायु गुणवत्ता काफी बिगड़ गई और एक्यूआई (वायु गुणवत्ता सूचकांक) 262 पर ‘खराब’ श्रेणी में पहुंच गया. न्यूज एजेंसी एएनआई की एक खबर के मुताबिक सिस्टम ऑफ एयर क्वालिटी एंड वेदर फोरकास्टिंग एंड रिसर्च (सफर) के अनुसार दिल्ली में सबसे खराब एक्यूआई विश्वविद्यालय इलाके में 327 में दर्ज किया गया जो ‘बहुत खराब’ श्रेणी में है. हर साल दिल्ली में अक्टूबर से वायु प्रदूषण का स्तर बढ़ जाता है. पराली जलाना, स्मॉग आदि कई कारणों से ये साल के अंत तक कायम रहता है. शुक्रवार को भी दिल्ली का एक्यूआई खराब श्रेणी में रहा था. अब दिल्ली में प्रदूषण के स्तर को नियंत्रित करने के लिए दिल्ली सरकार ने 28 अक्टूबर से ‘रेड लाइट ऑन गाड़ी ऑफ’ अभियान शुरू करने की घोषणा की है. दिल्ली में वाहनों के प्रदूषण को कम करने के लिए पहली बार 16 अक्टूबर, 2020 को शुरू किए गए इस अभियान के तहत ड्राइवरों को ट्रैफिक लाइट के हरे होने का इंतजार करते समय अपने वाहनों को बंद करने के लिए प्रोत्साहित किया जाता है. पेट्रोलियम कंजर्वेशन रिसर्च एसोसिएशन (पीसीआरए) के आंकड़ों से पता चलता है कि अगर लोग ट्रैफिक सिग्नल पर इंजन बंद कर देते हैं, तो प्रदूषण में 13-20% की कटौती की जा सकती है. सरकारी अनुमानों के अनुसार दिल्ली में PM2.5 उत्सर्जन में परिवहन क्षेत्र का हिस्सा 28% है. वाहनों से दिल्ली की हवा में 80% नाइट्रोजन ऑक्साइड और कार्बन मोनोऑक्साइड बनता है. जबकि सेंटर फॉर साइंस एंड एनवायरनमेंट (सीएसई) के एक रिसर्च में कहा गया कि जुलाई-सितंबर के दौरान दिल्ली का पीएम 2.5 प्रदूषण 5 साल में सबसे कम रहा. गौरतलब है कि शून्य से 50 के बीच एक्यूआई अच्छा, 51 और 100 संतोषजनक, 101 और 200 मध्यम, 201 और 300 खराब, 301 और 400 बहुत खराब, और 401 और 500 गंभीर माना जाता है.

Delhi PM 2.5 pollution in winters has dipped 20 pc compared to pre-pandemic period: Report

The assessment captured seven successive winters and pre-winter trends, starting from January 1, 2015 in Delhi and the National Capital Region (NCR). The average PM2.5 pollution in Delhi in the winter season has declined by about 20 per cent as compared to the pre-pandemic period, according to a new report released by the Centre for Science and Environment (CSE) on Thursday. The assessment captured seven successive winters and pre-winter trends, starting from January 1, 2015 in Delhi and the National Capital Region (NCR). It is based on real time data available from the 81 operational air quality monitoring stations in the region. The PM2.5 concentration for winter (October 1 to February 28) used to hover around 180-190 microgram per cubic metre before the pandemic. It has come down to 150-160 microgram per cubic metre since then, the report said. Anumita Roychowdhury, executive director of research and advocacy at the CSE, said the objective of the report is to understand the trend and ”the starting line of the onset of the winter pollution season or pre-winter levels in this region”. The seasonal average is still over 150 per cent above the 24-hour standard (60 microgram per cubic metre) and almost four times the annual standard (40 microgram per cubic metre) despite the improvement, the green thinktank noted. It said peak pollution showed a similar trend as the seasonal average. ”Peak pollution (worst 24-hour average) used to cross 800 microgram per cubic metre at individual stations pre-pandemic. It has been hovering in the 700-800 microgram per cubic metre range during the last three winters,” the report said. The CSE, however, said the peak pollution numbers did not project the actual level as the Central Pollution Control Board (CPCB) had capped it at 1,000 microgram per cubic metre in 2016-17, greatly compromising the assessment of peak pollution level. Researchers said the winter of 2021-22 was less polluted as compared to 2020-21 for most NCR cities. Ghaziabad registered a 30 per cent improvement, the highest among all major cities, but its PM2.5 level was still about 2.5 times the 24-hour standard, they said. ”Greater Noida (28 per cent), Noida (23 per cent) and Faridabad (16 per cent) also registered improvement in excess of Delhi (12 per cent),” the report said. Gurugram, with 11 per cent improvement, was the worst performer among the core NCR cities. In absolute concentration terms, Faridabad, with an average of 159 microgram per cubic metre, was the most polluted city of the NCR last winter. The report also highlighted that a different station in Delhi recorded peak pollution every winter over the last years. ”Shadipur, DTU, CRRI Mathura Road, JLN Stadium, Alipur, ITO and Rohini have occupied the worst peak pollution title in the last seven winters. These are spread across the city with no clear pattern. This indicates that the winter pollution is regional in nature and short-term peak build-up can happen anywhere based on local meteorology and pollution sources,” the report read.

Delhi Air Pollution: दिवाली से पहले बिगड़ी दिल्ली की आबोहवा, सांस लेना हुआ दुश्वार

Delhi Air Pollution: दिवाली से पहले ही राष्ट्रीय राजधानी दिल्ली ( Delhi air quality ) और आसपास के इलाकों की आबोहवा बिगड़नी शुरू हो गई है. आज यानी रविवार सुबह दिल्ली धुआं-धुआं दिखाई दी. इसके साथ ही वायु प्रदूषण भी उच्चतम स्तर पर रिकॉर्ड किया गया. सुबह हवा में घुले जहर के कारण मॉर्निंग वॉक पर निकलने वाले लोगों को सांस लेने में काफी कठिनाई का सामना करना पड़ा. हवा की ऐसी हालत ने सरकार और प्रदूषण विभाग को चिंता में डाल दिया है. हालांकि दिल्ली में दिवाली पर पटाखों का जलाया जाना बैन किया गया है, बावजूद इसके राजधानी में हवा की गुणवत्ता ( Air Quality Index ) खराब होने की आशंका जताई जा रही है. वहीं, हवा में आए इस बदलाव का मुख्य कारण किसानों द्वारा खेतों में जलाई जा रही पराली को माना जा रहा है. सिस्टम ऑफ एयर क्वालिटी एंड वेदर फोरकास्टिंग एंड रिसर्च (SAFAR) के अनुसार दिल्ली में एयर क्वालिटी इंडेक्स (AQI) 266 (खराब) श्रेणी में है.जानकारी के अनुसार कल धनतेरस के दिन दिल्ली के जुड़े पंजाब, हरियाणा और उत्तर प्रदेश जैसे राज्यों में पराली जलाने के मामलों ने जोर पकड़ लिया. एक रिपोर्ट के अनुसार अकेले पंजाब में ही 582 स्थानों पर पराली जलाई गई. इसी तरह हरियाणा में 122 जगहों पर पराली जली. इस तरह से पंजाब में पराली जलाने के अब तक 3114 और हरियाणा में 771 मामले सामने आ चुके हैं. जैसे-जैसे उत्तर भारत के इलाकों में ठंड बढ़ती जा रही है । ठीक वैसे वैसे यहां के कई राज्यों की हवा प्रदूषण की वजह से खराब होती जा रही है। दिल्ली एनसीआर कि कई शहरों की हवा तो लगातार खतरनाक से गंभीर श्रेणी में पहुंचकर खराब होती जा रही है.इसका कारण CPCB और CSE ने पराली को बताया है. सरकारी एप्लीकेशन सफर के मुताबिक आज सुबह 7 बजे दिल्ली का एयर क्वालिटी इंडेक्स 266 पीएम 2.5 के साथ बहुत खराब श्रेणी में दर्ज किया गया. इसके अलावा नोएडा में भी प्रदूषण का बुरा हाल है. यहां आज सुबह 311 खतरनाक श्रेणी में दर्ज किया गया. हालांकि गुड़गांव में यह 139 के साथ मोडरेट केटेगरी में रहा. लेकिन अनुमान है कि दीवाली के बाद यह प्रदूषण दिन पर दिन खतरनाक हो जाएगा.

A Diwali warning: ‘Conditions ripe for severe smog episode’

Analysis by Centre for Science and Environment also shows that recent winters saw a 20% improvement in winter air quality compared to the pre-pandemic years from 2015 to 2018 Recent winters show a 20% improvement in winter air quality compared to the pre-pandemic years from 2015 to 2018, according to an analysis by the Centre for Science and Environment (CSE). However, Diwali this year may trigger yet another smog episode, the analysis shows. At the ten oldest air quality monitoring stations in Delhi for which data is available, the average PM2.5 level in the 2015-16 winter was 193 µg/m3. At these ten stations, which include the ones at Anand Vihar, Mandir Marg, Punjabi Bagh, Dwarka and R K Puram, the average PM2.5 concentration in the 2021-22 winter was 151 µg/m3, while it was 162 µg/m3 in the 2020-21 winter, and 153 µg/m3 in the 2019-20 winter. The period from October 1 to February 28 is taken as winter.

PM2.5 pollution in Delhi during July-Sept quarter 2nd lowest in 5 years: CSE

Delhi"s PM2.5 pollution average for the July-August-September quarter this year stood at 37 microgram per cubic metre, only marginally higher than the five-year low of 36 microgram per cubic metre recorded during 2020, according to an analysis by the Centre for Science and Environment (CSE). Pollution levels in the July-August-September quarter were preceded by one of the most polluted summers this year, unlike in 2020 when the trimester followed the cleanest ever summer (March-May) due to extraordinary conditions created because of hard pandemic lockdowns, the green think tank said. "Therefore, it is important to understand what aided in cleaning up the Delhi air. Looking at the rainfall data it becomes evident that distribution of rainfall has a relatively higher impact on seasonal air quality than the absolute quantity of rainfall," it said. There have been 45 rainy days in July, August and September this year as compared to just 39 rainy days in the quarter last year. "These six extra rainy days helped keep the seasonal average low despite total rainfall this monsoon having been just one-third of the previous monsoon," the CSE said. These additional rainy days also pushed the regular start of bad air quality days further down the month of October, it said. The PM2.5 average for the quarter stood at 38 microgram per cubic metre in 2021, 41 microgram per cubic metre in 2019 and 43 microgram per cubic metre in 2018. The CSE had on Thursday said the average PM2.5 pollution in Delhi in the winter season has declined by about 20 per cent as compared to the pre-pandemic period. The PM2.5 concentration for winter (October 1 to February 28) used to hover around 180-190 microgram per cubic metre before the pandemic. It has come down to 150-160 microgram per cubic metre since then, it said. However, the seasonal average is still over 150 per cent above the 24-hour standard (60 microgram per cubic metre) and almost four times the annual standard (40 microgram per cubic metre) despite the improvement, the green think tank noted.

Delhi News:दिल्ली में बढ़ता प्रदूषण,GRAP के तहत कई पाबंदियां लागू

दिल्ली-एनसीआर में प्रदूषण का स्तर दीवाली से पहले ही तेजी से बढ़ रहा है. कई इलाकों में धुंध की चादर दिखाई दे रही है. पड़ोसी राज्य पंजाब-हरियाणा में पराली जलाने से उठता धुआं और गिरते तापमान के कारण प्रदूषण की काली चादर दिल्ली-NCR के आसमान पर धुंध बनकर छा गई है. दीवाली और उसके बाद प्रदूषण के हालात और बिगड़ने की आशंका है. शनिवार तक दिल्ली-NCR का एयर क्वालिटी इंडेक्स यानी AQI 300 से 400 पार होने की आशंका है. यही वजह है कि दिल्ली-NCR में ग्रेडेड रिस्पॉन्स ऐक्शन प्लान यानी GRAP के दूसरे चरण में कई पाबंदियां लागू की जा रही हैं. कोयला और लकड़ी से चलने वाले तंदूर वाले होटलों पर पाबंदी रहेगी – डीज़ल से चलने वाले जनरेटर बंद होंगे – अस्पताल, रेल जैसी ज़रूरी सेवाओं को छोड़कर पार्किंग फ़ीस बढ़ेगी ताकि निजी वाहन लोग कम चलाएं – CNG और इलेक्ट्रिक बस और मेट्रो सर्विस बढ़ेगी न्यूज एजेंसी पीटीआई ने विज्ञान एवं पर्यावरण केंद्र (सीएसई) के हवाले से गुरुवार को कहा कि इस साल दिवाली ऐसे वक्त में मनायी जा रही है जब पहले की अपेक्षा ज्यादा ठंड नहीं है लेकिन दिल्ली के पड़ोसी राज्यों में पराली जलाने से वायु प्रदूषण की समस्या बढ़ सकती है.

दिवाली के समय पराली जलाने से बढ़ सकती है समस्या, वायु गुणवत्ता और बदतर हो सकती है : सीएसई

नयी दिल्ली: विज्ञान एवं पर्यावरण केंद्र (सीएसई) ने गुरुवार को कहा कि इस साल दिवाली ऐसे वक्त में मनायी जा रही है जब पहले की अपेक्षा ज्यादा ठंड नहीं है लेकिन दिल्ली के पड़ोसी राज्यों में पराली जलाने से वायु प्रदूषण की समस्या बढ़ सकती है. दिल्ली-राष्ट्रीय राजधानी क्षेत्र (एनसीआर) में वायु गुणवत्ता प्रतिकूल मौसम विज्ञान संबंधी कारकों जैसे कम तापमान और हवा की गति के कारण अक्टूबर में बिगड़नी शुरू हुई थी जिससे प्रदूषकों का छितराव नहीं हुआ. पटाखों से होने वाला उत्सर्जन तथा पड़ोसी राज्यों में पराली जलाने से वायु गुणवत्ता और बदतर होगी. सीएसई ने कहा कि इस साल दिवाली पहले ही आ रही है, ‘‘जिसका मतलब है कि गर्म मौसम और हवा की स्थितियां प्रदूषण को कम करने में मदद करेगी जो दिवाली की रात के समारोहों का हिस्सा बन गया है. पिछले दो साल के मुकाबले इस बार पराली जलाने से निकलने वाले धुएं ने क्षेत्र में अभी तक वायु गुणवत्ता पर असर नहीं डाला है और अक्टूबर की शुरुआत में बारिश ने भी हवा को अभी तक अपेक्षाकृत साफ रखा है. ब्रेकिंग न्यूज़ हिंदी में सबसे पहले पढ़ें News18 हिंदी| आज की ताजा खबर, लाइव न्यूज अपडेट, पढ़ें सबसे विश्वसनीय हिंदी न्यूज़ वेबसाइट News18 हिंदी|
