Are Delhi’s air monitoring stations showing the real picture of pollution?

Talk about bad air quality in Delhi and the apocalyptic readings of east Delhi's Anand Vihar – a transport hub and arguably one of Delhi's most polluted and congested spots — pop up. But Delhi's pollution map is much more than this choked corner. When a 2015 study said Delhi's air is consistently more toxic than that in Beijing, SAFAR (System of Air Quality and Weather Forecasting and Research) chief Gufran Beig disputed the finding. He said comparing pollution levels of south Delhi's RK Puram with the US embassy in Beijing was not correct because of a huge geographical difference between the two locations.
