If you woke up in <keyword id="19900881" type="General" weightage="20" keywordseo="delhi" source="keywords">Delhi</keyword> recently, you might have noticed more than just the nip in the air – a thick, toxic smog has blanketed the city, turning the air almost unbreathable. On Monday, Delhi’s <keyword id="19920379" type="General" weightage="20" keywordseo="air-quality-index" source="keywords">Air Quality Index</keyword> (<keyword id="19916482" type="General" weightage="20" keywordseo="aqi" source="keywords">AQI</keyword>) hit 481, placing it in the "severe plus" category. For context, the “severe” category begins at an AQI of 401, and anything above 450 poses serious health risks even for healthy individuals. According to Swiss group IQAir’s live rankings, Delhi is currently the most polluted city in the world, with an air quality score of 1,081 – a “hazardous” level that is 130.9 times the World Health Organization’s recommended limit for PM2.5. <h3 style="line-height:1.38;margin-top:14pt;margin-bottom:4pt;">Major contributors to Delhi’s smog</h3>The root causes of Delhi’s pollution are manifold: <ul><li>Stubble Burning: On Saturday, crop residue burning contributed 25% of Delhi’s air pollution. By Sunday, this figure had climbed to 40%, according to SAFAR (System of Air Quality and Weather Forecasting and Research). Satellites recorded 1,334 stubble-burning incidents in six northern states on Sunday alone, the highest number in four days.</li><li>Vehicles: On Sunday, vehicular emissions accounted for 15.8% of the city’s pollution, according to the Centre’s Decision Support System for Air Quality Management.</li><li>Construction Dust and Industrial Emissions: PM2.5, a deadly pollutant, remains the most prominent factor, capable of penetrating deep into the lungs and leading to severe respiratory and cardiac diseases.</li></ul><h3 style="line-height:1.38;margin-top:14pt;margin-bottom:4pt;"><keyword id="24020184" type="General" weightage="20" keywordseo="GRAP-Stage-4" source="keywords">GRAP Stage 4</keyword></h3>To combat the rising pollution levels, authorities have enforced Stage 4 of the Graded Response Action Plan (GRAP). Here’s a breakdown of the restrictions: <ul><li>Vehicle Restrictions:</li><ul><li>Diesel medium and heavy goods vehicles (BS-IV and below) registered in Delhi are banned unless carrying essential goods.</li><li>Non-essential light commercial vehicles from outside Delhi can only enter if they use CNG, BS-VI diesel, or are electric.</li><li>Trucks carrying non-essential items are barred unless they use cleaner fuels like LNG, CNG, or BS-VI diesel. </li></ul><li>Workplace and School Adjustments:</li><ul><li>Classes for students in grades 6 to 9 and class 11 have moved online.</li><li>Offices in the National Capital Region (NCR) are advised to work at 50% capacity, with the rest operating remotely. </li></ul><li>Construction Ban: </li><ul><li>Construction and demolition (C&amp;D) activities have been halted, including large projects like highways, flyovers, and pipelines. </li></ul></ul>Out of Delhi’s 40 monitoring stations, 32 reported AQI levels above 400 on Monday. Visibility in parts of the city dropped to just 100 metres due to the thick smog. The health implications of these numbers are alarming. <keyword id="20118319" type="General" weightage="20" keywordseo="PM2-5-levels" source="keywords">PM2.5 levels</keyword> in Delhi were recorded at 130.9 times the safe limit set by the WHO. According to experts, long-term exposure to such air quality could lead to an 11% increase in premature mortality rates due to respiratory and cardiovascular diseases. Studies have shown that Delhi residents may lose an average of 10 years of life expectancy if pollution levels persist. Despite the restrictions, life in Delhi continues under a cloud of smog. Iconic landmarks like India Gate have become barely visible through the haze. While flights and trains are operational, some delays have been reported.

GRAP Stage 4 restrictions take effect as air quality in Delhi deteriorates; PM2.5 levels 130 times higher than WHO limits

Emissions from residential cooking and heating, power generation, and industries together contribute up to 60 per cent of India's PM2.5 pollution, with about 80 per cent of this coming from <keyword id="23824528" type="General" weightage="20" keywordseo="fossil-fuel-combustion" source="keywords">fossil fuel combustion</keyword>, a new study has found. The peer-reviewed study, published in MDPI's "Air" journal, suggests dividing India into 15 airsheds based on regional climate and pollution sources. An airshed is a geographic area where <keyword id="53848" type="General" weightage="100" keywordseo="air-quality" source="Orion">air quality</keyword> is influenced by common factors such as wind patterns and pollution sources. Since pollution can spread across regions, the <keyword id="22077484" type="General" weightage="20" keywordseo="airshed-approach" source="keywords">airshed approach</keyword> promotes coordinated action among states. "Residential cooking and heating, power generation, and all other industries together are responsible for 40-60 per cent of the PM2.5 pollution in all the airsheds, and approximately 80 per cent of the pollution comes from fossil fuel burning sources," said Sarath Guttikunda, lead author of the study and founder of UrbanEmissions.info. The study said biomass burning, including post-harvest crop residue burning, contributed less than 3 per cent to annual PM2.5 levels while transport accounted for 5-10 per cent in all airsheds. PM2.5 are fine particles with a diameter of 2.5 micrometres or less, about the width of a human hair. These are so small that these can penetrate deep into the lungs and even enter the bloodstream, posing significant health risks. An analysis of PM2.5 trends from 1998 to 2020, along with state-level data on fuel consumption, energy demand and emissions, revealed that 11 of the 15 airsheds were critical for India's air quality management and required coordinated interventions. The Indo-Gangetic Plains remain the most polluted region, with significant emissions from residential cooking and heating (especially in winter), power plants, brick kilns (driven by construction demand), waste burning, dust and vehicular movement for passengers and freight. The plateau region between the Eastern and Western Ghats, India's second most populated area, has seen the highest rise in annual PM2.5 pollution during this period, the study said. "This is an indication of the growing urbanisation and demand for transport, industrial, and commercial amenities," it said. Coastal areas, vital to India's industrial economy, have also experienced rising pollution despite the moderating effects of land-sea breezes. This increase is attributed to growing shipping emissions and overall industrial growth in cities such as Mundra, Surat, Mumbai, Goa, Mangalore, Kochi, Thiruvananthapuram, Chennai, Visakhapatnam, Paradip and Haldia.

Study traces 60% PM2.5 pollution in India to residential cooking, power generation, industries

Imagine taking a deep breath, expecting fresh, clean air, but instead, inhaling particles so tiny they’re invisible but powerful enough to change your life. For millions worldwide, that’s the reality — and it’s taking a toll on their lungs. A new global study shows that nearly 30% of <keyword id="22476122" type="General" weightage="100" keywordseo="asthma-cases" source="keywords">asthma cases</keyword> can be traced back to long-term exposure to <keyword id="20147117" type="General" weightage="20" keywordseo="fine-particulate-matter" source="keywords">fine particulate matter</keyword>, or <keyword id="20573061" type="General" weightage="20" keywordseo="PM2-5" source="keywords">PM2.5</keyword>, the kind of pollution that often comes from cars, factories, and even cooking fires. <h2>How PM2.5 impacts asthma</h2>Asthma is a chronic respiratory condition characterised by recurring symptoms like wheezing, coughing, and difficulty breathing. While the exact causes of asthma remain complex and varied, this new study underlines that PM2.5 pollution is a significant risk factor. The study brings together insights from 68 epidemiological studies conducted across 22 countries, spanning regions from North America to South Asia. This comprehensive meta-analysis demonstrates the consistent impact of PM2.5 on asthma development. <div type="Article" hostid="261" msid="114504550" title="Most people miss THIS warning on their mosquito repellent vaporizer’s label" mstype="2" mssubtype="0"></div>Lead author Dr Ruijing Ni explained, “We estimate that globally in 2019, almost a third of asthma cases are attributable to long-term PM2.5 exposure, corresponding to 63.5 million existing cases and 11.4 million new cases.” <h2>The Indian asthma problem</h2>India, one of the world’s most polluted countries, faces a particularly severe burden from <keyword id="19900550" type="General" weightage="20" keywordseo="air-pollution" source="keywords">air pollution</keyword>. Studies have shown that PM2.5 levels in many Indian cities far exceed the <keyword id="19896311" type="General" weightage="20" keywordseo="World-Health-Organization" source="keywords" meta.keywordsubtype="org" meta.entityname="World Health Organization" meta.hostid="261" meta.entityid="World Health Organization">World Health Organization</keyword>'s safe limit of 5 µg/m³. This exposure is especially dangerous for children, whose lungs and immune systems are still developing. The numbers are worrying: around 15-20 million Indians suffer from asthma, making up a significant portion of the estimated 339 million cases worldwide. Children are disproportionately affected; a 2019 report indicated that approximately 6% of children aged 1 to 5 in India show asthma symptoms. This exposure often results in airway inflammation and oxidative stress, which increases vulnerability to <keyword id="19923193" type="General" weightage="20" keywordseo="respiratory-diseases" source="keywords">respiratory diseases</keyword>. <h2>What the data says</h2>The research team employed exposure-response curves to better understand the link between PM2.5 levels and asthma cases. By considering data from both high-income and low- and middle-income countries, the researchers could provide a more accurate global assessment of PM2.5’s <keyword id="21037424" type="General" weightage="20" keywordseo="health-impact" source="keywords">health impact</keyword>. The study found that in Germany, for instance, PM2.5 may be responsible for about 11% of new asthma cases — roughly 28,000 people. However, the burden is even higher in low- and middle-income countries like India, where higher levels of pollution are coupled with limited healthcare access. This disparity highlights the need for global action to reduce PM2.5 emissions, especially in regions where pollution levels and health impacts are most severe. <h2>Policy implications and recommendations</h2>The findings have clear implications for policymakers. Strengthening <keyword id="19918941" type="General" weightage="20" keywordseo="air-quality" source="keywords">air quality</keyword> regulations, especially in high-exposure regions, could prevent millions of new asthma cases and reduce healthcare costs. “Our findings highlight the urgent need for policymakers to enforce stringent legislation to continuously combat air pollution,” emphasised another study author Prof. Yafang Cheng. <div type="Article" hostid="261" msid="114695519" title="Are your green firecrackers really ‘green? Here’s all you need to know before doing your Diwali shopping" mstype="2" mssubtype="0"></div>In addition to governmental measures, personal protective actions like wearing masks and installing air purifiers in homes can also help individuals reduce their exposure to PM2.5, particularly during high-pollution periods. This study adds to the growing evidence that reducing air pollution is critical for public health. While global challenges like PM2.5 pollution may seem daunting, each step toward cleaner air can bring significant health benefits. For countries like India, where asthma rates and pollution levels are both alarmingly high, these findings underscore an urgent need for both policy and community action to protect the most vulnerable — particularly children.

Air Quality Alert: Nearly 30% of asthma cases tied to fine particulate matter exposure from bad air

Have you ever considered that your regular commute to and fro work could potentially shave off some years from your life? And no, we’re not talking about road traffic accidents but the slow poison we’re inhaling unbeknownst to us: air pollutants. A new study published in <a href="https://www.thelancet.com/journals/lanplh/article/PIIS2542-5196(24)00114-1/fulltext">The Lancet Planetary Health</a> by an international team of researchers reveals a terrifying truth: over 7% of daily deaths in 10 major <keyword id="20026638" type="General" weightage="20" keywordseo="Indian-cities" source="keywords">Indian cities</keyword> are attributed to <keyword id="19900550" type="General" weightage="20" keywordseo="air-pollution" source="keywords">air pollution</keyword> caused by <keyword id="22110704" type="General" weightage="20" keywordseo="PM2-5-pollutants" source="keywords">PM2.5 pollutants</keyword> exceeding the World Health Organization's (WHO) safe limits. These PM2.5 pollutants are microscopic particles, 2.5 micrometres or less in diameter, that come from <keyword id="2839914" type="General" weightage="20" keywordseo="vehicle-emissions" source="Orion">vehicle emissions</keyword> and industrial activities. Imagine tiny daggers — that's what these PM2.5 particles are like, infiltrating deep into lungs and even the bloodstream, wreaking havoc on our health. The study found that PM2.5 levels breach WHO guidelines a staggering 99.8% of the time in these cities. The analysis covered major cities like Delhi, Mumbai, Bengaluru, Ahmedabad, Chennai, Hyderabad, Kolkata, Pune, Shimla and Varanasi. A staggering 7.2% of deaths in these cities, translating to roughly 33,000 annually, were associated with short-term PM2.5 levels exceeding the WHO's recommended limit (15 micrograms per cubic metre) between 2008 and 2019. Delhi, unfortunately, takes the crown for the most polluted. A shocking 11.5% of its annual deaths are attributed to air pollution, translating to a devastating 12,000 lives lost each year. The link between PM2.5 and mortality is undeniable. Researchers found that a mere 10 microgram per cubic metre increase in these pollutants correlates with a 1.4% rise in daily deaths. This risk factor doubles when considering only levels below India's air quality standards, which are, worryingly, less strict than the WHO's recommendations. But here's a surprising twist: the association between PM2.5 and death is even stronger in cities with generally cleaner air, like Bengaluru and Chennai. This suggests that locally produced pollutants, from sources like construction dust or waste burning, might be significant contributors. There is a glimmer of hope, however. The study emphasises that implementing stricter air quality standards and utilising proven pollution control methods from other parts of the world can be game changers. Lowering and enforcing stricter air quality limits will save tens of thousands of lives per year, emphasises Joel Schwartz, a co-author from Harvard University. This study serves as a stark wake-up call. The air we breathe in many Indian cities is a gamble, with every breath potentially harmful. Taking decisive action to curb pollution is not just about a cleaner environment, it's about saving the lives of millions of Indians.

In her letter, dated August 30, Banerjee emphasised the gravity of the situation and urged for prompt central intervention, highlighting the inadequacy of the reply received from the Union Minister of <keyword id="20086338" type="General" weightage="20" keywordseo="Women-and-Child-Development" source="keywords">Women and Child Development</keyword>. The letter reads, "No reply was received from your end on such a sensitive issue. However, a reply has been received from the Minister of Women and Child Development, Government of India (vide their No. 1/RESC/HMWCD/2024 dated 25th August 2024), which barely addresses the gravity of the issue raised in my letter. I am of the view that the seriousness of the subject and its relevance to society have not been adequately appreciated in this generic reply." The letter was posted on her social media handle, X. In response to Union Minister Annapurna Devi's allegations regarding the state government's failure to implement essential safety measures for women and children, including Fast Track Special Courts (FTSCs), CM Mamata stated that the state government has approved 10 exclusive POCSO FTSCs, while 88 FTSCs and 62 POCSO-designated Courts are functioning with complete state funding. The letter mentioned, "Moreover, I would also refer to some of the initiatives in this area that our State has already undertaken, which appear to have been overlooked in the reply. Regarding Fast Track Special Courts (FTSCs), 10 exclusive POCSO Courts have been approved by the State Government. In addition to this, 88 FTSCs and 62 POCSO-designated Courts are functioning throughout the State with complete State funding. Monitoring and disposal of cases are entirely in the hands of the Courts." Highlighting the issue of appointing Presiding Officers in FTSCs, she further stated that this process requires examination and action from the Government of India, which, according to her, needs PM Modi's intervention. "As per Central Government guidelines, only retired Judicial Officers can be posted as Presiding Officers in FTSCs, but the Hon'ble High Court has observed that, in view of the severity of the cases, permanent Judicial Officers need to be appointed. This requires examination at the level of the Government of India and appropriate action thereafter, for which your intervention would be necessary. Moreover, Helpline Nos. 112 and 1098 are functioning satisfactorily in the State. Additionally, Dial 100 is also extensively used in emergency situations," the letter added. Urging for central <keyword id="20082569" type="General" weightage="20" keywordseo="legislation" source="keywords">legislation</keyword> and exemplary punishment for heinous crimes, the West Bengal CM expressed hope for very considered attention from PM Modi. Mamata Banerjee mentioned in her letter, "I would reiterate and earnestly request that a stringent Central legislation and exemplary punishment for heinous crimes of rape/rape and murder be considered, with a mandatory provision for the disposal of cases within a specific timeframe by the trial authorities. I hope this matter would receive very considered attention at your kind end in the interest of our society at large." On August 26, Union Women and Child Development Minister Annapurna Devi criticised the West Bengal government for its failure to implement essential safety measures for women and children in the state. In a letter written to West Bengal CM Mamata Banerjee, the Union Minister stated that 123 Fast Track Special Courts (FTSCs) were allocated to the state, but none of them are functional yet. Earlier, on August 22, West Bengal CM Mamata Banerjee wrote a letter to Prime Minister Narendra Modi urging the central government to bring in central legislation and set up fast-track courts for "sensitive" issues to ensure a speedy trial. Mamata, in the letter, mentioned that such "sensitive" issues need to be addressed comprehensively through stringent central legislation prescribing exemplary punishment against the perpetrators of such heinous crimes. The Bengal Chief Minister suggested the setting up of "fast-track special courts" to deal with such cases, which require a speedy trial. This development comes after the trainee doctor was found dead in the seminar hall of RG Kar Medical College and Hospital in Kolkata on August 9.
