Air pollution has returned to haunt Delhiites and this time it appears to be more lethal than ever.
Residents of the national Capital, who were breathing easy after the introduction of CNG and green vehicles in the past few years, have reason to worry about the air they inhale.
A recent study by Jawaharlal Nehru University (JNU) has revealed that the air in Delhi is full of carcinogenic (cancer causing) particles. JNU’s department of environmental sciences has come out with a toxicological risk assessment report that points out alarming levels of aerosol and heavy metals in the city’s air.
The study was sponsored by the University Grants Commission and supported by the Ministry of Environment and Forests and published by the National Academy of Sciences recently.
The presence of particulate matter (PM), inhalable particles, in both diameter – PM2.5 and PM10 – and cancercausing heavy metals such as nickel and cadmium in the Capital’s air has been found to be exceeding the permissible limits at peak traffic hours.
