Covid lockdown in India didn't cut air pollution as much as thought: Study

Air quality in India did not improve as much during the first COVID-19 lockdown as originally thought, according to a study which found that ozone levels increased even as other pollutants decreased. The researchers at York University in Canada noted that observational data shows air pollution in India decreased drastically in the first COVID-19 lockdown last year when emissions from vehicles naturally declined. However, they noted that blue skies and an absence of visible smog can be deceiving and hide pollutants that could potentially cause health issues. The study, published in the journal Environmental Science: Processes & Impacts, found that some air pollutants didn't drop nearly as much as first thought and even more surprising was that ozone levels increased even as other pollutants decreased. The air looked much cleaner, but that allowed more sunshine to get through, creating conditions for ozone (O3) to increase up to 30 per cent, according to the researchers. "Our ...

Delhi's air very poor; no improvement in sight for another 3 days

Delhi's air quality deteriorated marginally on Monday and no improvement is predicted over the next three days, authorities said. The share of stubble burning in Delhi's pollution stood at 10 per cent on Monday, the lowest since Diwali (November 4). On an average, farm fires have accounted for around 25 per cent of the PM2.5 pollution in Delhi from November 1 to November 15. According to an analysis by the Delhi Pollution Control Committee (DPCC), people in the national capital breathe the worst air between November 1 and November 15 every year, as unhelpful meteorological conditions trap pollutants from local sources and stubble burning in neighbouring states of Punjab and Haryana. Delhi's 24-hour average air quality index stood at 353 at 4 pm. A significant drop in emissions from farm fires had brought the capital's 24-hour average AQI down from 437 on Saturday to 330 on Sunday. An AQI between zero and 50 is considered 'good', 51 and 100 'satisfactory', 101 and 200 'moderate',
