Air quality tests done in Delhi and Gurugram in the last two months has shown a presence of alarming levels of toxic heavy metals.
A recent report titled 'Death in Every Breath', released by NGO Lung Care Foundation analysed results of seven air quality tests taken in the two cities.
The PM 2.5 levels - fine particulate matters in the air with a diameter of less than 2.5 micrometres - in all the seven tests were above statutory limits, the report said.

The opposition Labour Party, backed by other smaller opposition parties, has put forward a motion which states "that this House has no confidence in Her Majesty's Government."
Labour leader Jeremy Corbyn will open the debate on the motion at around 1300 GMT.
May will also speak in the debate and it will last until 1900 GMT.
Lawmakers will then vote on the motion at 1900 GMT, with the result due at around 1915 GMT.

Children are particularly vulnerable to the effects of lead.
'It is a matter of very serious concern that such high levels of these toxic metals are found in the air that our children breathe,' said Arvind Kumar of Lung Care Foundation.

The report also found high levels of barium from Diwali fireworks.
'The barium level in the air quality test a day before Diwali is 21.5 g/m3, on the day of Diwali the test has barium level of 5.8 g/m3, and a day after Diwali, the barium level in the test is 2.4 g/m3,' the report said.
