Delhi's air is the worst among world megacities, the World Health Organization (WHO) confirmed recently, even as IndiaSpend's #breathe network of air-quality sensors reported fine-particulate-matter (PM2.5) levels were almost four times above daily safe levels, on average, for the seven-day period from September 22 to 28, 2016.
For long-term exposure, these 24-hour levels are nearly 11 times above the WHO health standards. Over the monsoons, Delhi's air was relatively cleaner because the rain and wind diminished the impact of pollutants. But with the season changing, three of our five sensors in the National Capital Region (NCR) registered "poor" to "very poor" air-quality levels from September 22 to 28, meaning prolonged exposure affects healthy people and "seriously impacts" those with existing disease. In December 2015, week-long analysis of data from #breathe devices showed Delhi's air pollution was one-and-a-half times worse than in Beijing, IndiaSpend reported.
In 2012, with one million deaths, China reported the highest toll from PM2.5 and PM10 pollution. At the time, India followed, reporting 621,138 deaths, nearly 10 per cent of the global toll (6.5 million deaths) associated with outdoor and indoor air pollution.
