Alarming levels of toxic heavy metals

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.

Increase in cancer causing Neuro-toxic elements

'Levels of lead in six of the seven tests exceed the US EPA 3-month average for exposure to lead (0.15 ug/m3) and in two tests exceeds the Indian NAAQS Annual and the WHO annual health-based guidelines value of 0.05 ug/m3,' the report said.

Nickel levels in all the tests exceed the WHO annual health-based guidelines value of 0.0025 ug/m3, which is based on the risk of cancer associated with long-term exposure to nickel.

Manganese, lead and nickel are neurotoxins that damage the brain.

Adverse consequences on children

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.
