Air pollution raises risk of eye infection, other ocular problems: Doctors

Air pollution is considered a reason for respiratory and cardiac problems. However, experts warn that it also increases the risk of eye infection and aggravates existing issues among those with ocular problems. Doctors hold fine particulates -- PM2.5 -- the main culprit for eye problems such as allergic conjunctivitis, scratches on the surface of the eyes, dryness, blurred vision, and increased sensitivity to light. "Every winter, my clinic sees a rise in the number of people complaining of red, itchy, watery, and burning eyes. The main reason is high air pollution, especially fine particles known as PM2.5," said Dr Ajay Sharma, co-founder of Eye Q Eye Hospital. PM2.5 includes tiny particulates from vehicle smoke, dust, burning waste, and firecrackers, he said, adding that these particles are so small that they easily enter the eyes and settle on the cornea, the clear front layer of the eye. Solid particles irritate and scratch the eye's surface, while liquid particles carry chemic

Grap 3 curbs enforced in Delhi-NCR as AQI may turn 'severe' in coming days

The Commission for Air Quality Management in NCR and Adjoining Areas or CAQM on Friday invoked GRAP curbs after the air quality showed an increasing trend, according to officials. The air quality index (AQI) in Delhi, which was 343 at 4 PM on Thursday, rose to 354 at 4 PM on Friday, the officials said. "Further, forecasts for weather ad meteorological conditions by the IMD/IITM indicate that due to slow wind speed, stable atmosphere, unfavourable weather parameters and meteorological conditions and lack of dispersal of pollutants, Delhi's average AQI is likely to breach the 400-mark and enter the severe' category in the coming days," a senior official said. "Keeping in view the prevailing trend of air quality, AQI forecasts and to prevent further deterioration, the CAQM sub-committee on GRAP (Graded Response Action Plan) today took the call to invoke all actions as envisaged under Stage-III of extant GRAP with immediate effect in the entire NCR as a proactive measure," the official

Air quality 'nationwide crisis', govt response ineffective: Congress

The Congress on Sunday cited a report to claim that air quality is a nation-wide, structural crisis for which the government response is "exceedingly ineffective and inadequate", as it demanded a thorough reform of the National Clear Air Programme. Congress general secretary in-charge communications Jairam Ramesh said the NCAP propagated as the National Clear Air Programme is actually another type of NCAP - "Notional Clear Air Programme". The former environment minister said a new analysis by the Centre for Research on Energy and Clean Air (CREA) has now confirmed what was always India's "worst-kept secret that the air quality is a nation-wide, structural crisis for which the government response is exceedingly ineffective and inadequate". Using satellite data, the study found that nearly 44 per cent of Indian cities that is 1,787 out of 4,041 statutory towns assessed have chronic air pollution, with annual PM2.5 levels consistently exceeding the national standard over five years ...

Jitendra Singh inaugurates lab to certify air pollution monitoring tools

Union Science and Technology Minister Jitendra Singh on Monday inaugurated a laboratory to test and calibrate equipment to monitor air pollution, one of the very few such facilities in the world. Singh inaugurated the National Environmental Standard Laboratory at the CSIR-National Physical Laboratory (NPL) premises here, and described it as a critical step towards strengthening India's environmental governance framework. Singh said the facility will reduce India's dependence on foreign certification agencies, save foreign exchange, shorten turnaround time for calibration, and enhance investor confidence in the country's rapidly expanding solar sector. The minister also inaugurated the National Primary Standard Facility for Solar Cell Calibration (Solar Energy Complex), terming it a "future-ready facility" that places India among a select group of global leaders in photovoltaic measurement standards. Addressing the 80th Foundation Day celebrations of Centre for Scientific and ...

Delhi air quality improves slightly, AQI returns to 'poor' category

Delhi saw a marginal respite in air quality on Monday as the 24-hour average Air Quality Index (AQI) improved to 244, in the poor' category, after lingering in the very poor' range a day earlier. Data from the Central Pollution Control Board's Sameer app showed that four stations recorded very poor' air quality, with Chandni Chowk logging the worst AQI at 321, while 25 stations remained in the poor' category and nine recorded moderate' air quality. According to the CPCB classification, an AQI between zero and 50 is considered good', 51 to 100 satisfactory', 101 to 200 moderate', 201 to 300 poor', 301 to 400 very poor' and 401 to 500 severe'. The Decision Support System indicated that Delhi's pollution load was led by transport at 13.7 per cent, followed by peripheral industries at 11.4 per cent, residential sources at 3.3 per cent, construction at 1.2 per cent and waste burning at one per cent. Among NCR districts, Jhajjar contributed the highest at 19.6 per cent, followed by Sonip

65% of Delhi's air pollution in 2025 originated from outside the city: CREA

As much as 65 per cent of Delhi's air pollution in 2025 originated from outside the city, mainly from other NCR districts, while local sources accounted for the remaining 35 per cent, a study said. According to an analysis by the Centre for Research on Energy and Clean Air (CREA), accessed by PTI, winter-period inputs from the Decision Support System indicated that pollution transported into the national capital outweighed emissions generated within the city during 2025. Winter-period source attribution figures showed that vehicular emissions accounted for nearly half of Delhi's local PM2.5 pollution, surpassing contributions from industry, construction and other combustion sources, even as transboundary pollution remained the dominant overall contributor. "Transboundary pollution from NCR districts and neighbouring states plays a major role in Delhi's air pollution. Delhi's geographical location also makes it vulnerable, as northerly and north-westerly winds carry polluted air from
