Delhi&#39;s much-talked about &quot;anti-smog gun&quot; failed to do very much.&nbsp;

The gun was rolled out and &quot;atomised water&quot; water fired from it at Anand Vihar ISBT on Wednesday but PTI reported that PM 2.5 and PM 10 levels continued to rise.&nbsp;

The gun was <a href="http://www.wionews.com/india-news/delhi-government-to-test-anti-smog-gun-today-27242" target="_blank">thrown into battle</a> around 10 am.&nbsp;

But, PTI reported, the hourly readings of PM 2.5 between 10 am and 2 pm were: 444, 421, 476, 509 and 460&nbsp;micrograms per cubic metre (ug/m3)&nbsp;

The hourly readings of PM 10 were 630, 608, 736, 842 and 702.

The 24-hour prescribed limits of the ultra-fine pollutants, which trigger respiratory and cardiovascular issues, are 60 and 100 respectively.

The anti-smog gun is attached to a water tanker, and shoots out tiny droplets of water -- atomised water -- as high as 50 metres.&nbsp;

It is hoped tiny pollutants (like PM 2.5 and 10) will then stick to the droplets and fall back to the ground, cleaning out the air somewhat like rain does.&nbsp;

Delhi Environment Minister Imran Hussain was at the trial.

He said the government would take a call on whether to use the gun elsewhere in the city after monitoring data collected by a Delhi Pollution Control Committee team.&nbsp;

The gun costs like Rs 20 lakh a piece.&nbsp;
