“Following India’s government announcement that it would launch a “massive” people-oriented awareness campaign to check air pollution, NDTV brought together leaders, including NRDC representatives, to discuss India’s growing air quality problems and potential solutions. Amidst growing popular concerns and expert opinions in Delhi, a sophisticated global study shows deteriorating air quality in India and other vulnerable regions. Researchers from Canada’s Dalhousie University collected data fromsatellite monitoring systems to analyze global fine particulate matter (PM2.5) trends between 1998 and 2012. The study found that South Asia had the second highest concentration of PM2.5 in the world, with an annual population-weighted mean exposure of 34.6 micrograms per cubic meter (µg/m3). Areas in northern India surpassed 60 µg/m3 of PM2.5–roughly six times the World Health Organization (WHO) air quality standard of 10 µg/m3.” Natural Resources Defense Council (NRDC) – Staff Blog.
