Air pollution leads to anxiety, decrement of cognitive ability: Doctors

As severely-polluted air has choked Delhi, doctors in the city have warned people, saying air pollution affects not just the lungs, but also other major organs, such as the heart and the brain, across all age groups. There has been a sudden increase in cases of headache, anxiety, irritation, confusion and decrement of cognitive abilities, especially among the vulnerable populations such as the elderly, schoolgoing children and pregnant women, Dr Neeraj Gupta, head of the pulmonary medicine department at the Safdarjung Hospital, told PTI. "Neurocognitive ability is directly linked to rising nitrogen dioxide, sulphur dioxide and carbon monoxide in the air as they impact the nervous system. "So gas chamber is a technically correct term to be used because of the rise of the concentration of harmful gases and not just particulate matter," he said. Gupta further said a study conducted in North Carolina among schoolgoing children has shown that the Air Quality Index (AQI) has a direct imp

Limit number of vehicles per family to curb air pollution, say experts

Rise in air pollution is linked to growing respiratory ailments in India, experts have said and urged the government to bring a policy limiting the number of cars per family and restricting the number of vehicles plying on roads at a time. On the sidelines of the 25th National Conference on Pulmonary Diseases (NAPCON-2023), organised by the Indian Chest Society here, Dr Rakesh K Chawla, the chairman of Pulmonology and Critical Care at Jaipur Golden Hospital, said air pollution has short-term as well as long-term effects on health. "The immediate effects are in the form of irritation in the eyes and throat. Also, there is an increase in the severity of asthma attacks," said Dr Chawla, who is also the organising chairman of NAPCON-2023. The conference was organised to discuss air pollution and diseases caused by it as well as the advancements in the field of pulmonology. Dr Chawla said the long-term effects of air pollution include respiratory diseases and lung cancer, and the worst

Delhi most polluted city in past year, Mizoram sustains cleanest air: Study

Although its air quality improved marginally, Delhi remained the most polluted city in the year ending September 30, with a PM2.5 concentration of 100.1 micrograms per cubic metre, which is three times the government's safe limit, according to a new analysis. The analysis conducted by independent think tank Climate Trends and tech firm Respirer Living Sciences, that manufactures real-time IoT-based air quality monitoring devices, showed that Aizawl and Mizoram have India's cleanest air with a PM2.5 level of only 11.1 micrograms per cubic metre. Four more cities from the National Capital Region -- Faridabad (89 micrograms per cubic metre), Noida (79.1 micrograms per cubic metre), Ghaziabad (78.3 micrograms per cubic metre) and Meerut (76.9 micrograms per cubic metre) -- also feature among the top 10 most polluted cities. The report is based on the analysis of the government's PM2.5 data from October 1, 2022, to September 30, 2023, and focuses on the cities covered under the National

Nanoparticle emissions from vehicles in Delhi pose health risks: Study

Delhi has been experiencing hazardous levels of nanoparticles in urban air, especially in the roadside environment, directly related to vehicular engine exhaust, raising pubic health concerns, according to a study. Nanoparticles are minuscule particles, often measuring between 10 to 1000 nanometers (nm) in diameter, making them invisible to the naked eye. These particles are more dangerous to human health due to their much smaller size compared to PM 2.5 or PM 10. Being 600 times smaller than a human hair, they can penetrate deep into our lungs, bloodstream, and even the brain. The study, published in the journal Urban Climate, was conducted on Bawana Road in northwest Delhi, connecting Delhi to Rohtak in Haryana. The monitoring location is surrounded by educational institutions, households, and commercial areas where the dominant source of pollution is vehicular, the researchers said. Other sources include biomass burning, fuel used for residential heating in winter, and firework

Exposure to air pollution linked to increased stroke risk within 5 days

Short-term exposure to air pollution may be linked to an increased risk of stroke, according to a study. The meta analysis, published recently in the the journal Neurology, defined short-term exposure as occurring within five days of the stroke. A stroke can cause lasting brain damage, long-term disability, or even death. Signs of a stroke can range from mild weakness to paralysis or numbness on one side of the face or body. "Previous research has established a connection between long-term exposure to air pollution and an increased risk of stroke," said study author Ahmad Toubasi, from the University of Jordan in Amman. "However, the correlation between short-term exposure to air pollution and stroke had been less clear. For our study, instead of looking at weeks or months of exposure, we looked at just five days and found a link between short-term exposure to air pollution and an increased risk of stroke," Toubasi said. The analysis involved a review of 110 studies that included

PM10, PM2.5 levels in Delhi down 45% since 2014: Environment Minister

In a "big relief" for Delhi residents, the PM10 and PM2.5 levels have declined by an average of 45 per cent in the last 9 years, Delhi Environment Minister Gopal Rai said on Tuesday. Speaking to reporters here after a meeting with officials of the environment department, Rai said that work on a 'winter action plan' to tackle any rise in air pollution levels has begun. The levels of particulate matter (PM) 10 and 2.5 usually start increasing from the last week of October and attain a peak in November when temperature plummets, requiring measures to check the poor quality of air, he added. "There is news of big relief for Delhi's people. The PM 10 and PM 2.5, which are two important parameters of air quality and determine the level of air pollution in Delhi, have registered a downward trend since 2014 due to efforts of Delhi's people and the government," the minister said. However, the Delhi government under the leadership of Chief Minister Arvind Kejriwal is determined to bring it .
