Today we review several articles about the state of air pollution in Delhi, India which is 15 times higher (153 micrograms per cubic meter) than the maximum level recommended by the World Health Organization. Not only is the air pollution poorer in Delhi than in Beijing but it is monitored at only 4 locations compared to more than 30 in Beijing. President Obama’s exposure to Delhi’s pollution (average 76 to 84 micrograms per cubic meter) during his recent 3 day visit may have reduced his life expectancy by 6 hours.
