The air pollution event that the article refers to was for a very short duration & was an episodic event due to a meteorological phenomenon.

The dust storm in the western region started on 13 June around 18:00 hrs and ended on 16 June around 05:00 hrs. The data from the official monitors in one of the western regions of Delhi NCR can be seen here: http://bit.ly/CPCB_Haryana_1Jun-16June2018

The headline in the above article is over-dramatic & is lacking a proper understanding of the actual ground-level monitored situation of those two days. What is more harmful is sustained levels of 500 ug/m3 of PM2.5 pollutants rather than a couple of spikes (each lasting less than a few hours) of 999 ug/m3.
