India to Measure Air Quality in World's Most Polluted Capital

India to Measure Air Quality in World's Most Polluted Capital

New Delhi:

The government today launched a new air quality index on, under intense pressure to act after the World Health Organization (WHO) declared New Delhi the world's most polluted capital.

Environment Minister Prakash Javadekar said the government would publish air quality data for 10 cities, amid growing public concern over the impact of air pollution on the health of India's 1.2 billion people.

The new index will initially cover 10 cities -- Delhi, Agra, Kanpur, Lucknow, Varanasi, Faridabad, Ahmedabad, Chennai, Bangalore and Hyderabad -- each of which would have monitoring stations with Air Quality Index display boards. The aim is to eventually cover 66 cities, the government said.

The government's website with the index went live on Monday morning.

"The Air Quality Index may prove to be a major impetus to improving air quality in urban areas, as it will improve public awareness in cities to take steps for air pollution mitigation," Mr Javadekar said as he launched the index at a conference on the environment.

But the Minister gave little indication of what the government would do to improve air quality, except to say it would introduce new rules on disposal of construction waste.

The dust from thousands of industrial and construction sites adds to the fumes from millions of vehicles to create the toxic cocktail that urban Indians breathe.

At least 3,000 people die prematurely every year in Delhi because of high exposure to air pollution, according to a joint study by the Boston-based Health Effects Institute and Delhi's Energy Resources Institute.

A World Health Organization study of 1,600 cities released last year showed Delhi had the world's highest annual average concentration of small airborne particles known as PM2.5 -- higher even than the Chinese capital Beijing.

These extremely fine particles of less than 2.5 micrometres in diameter are linked with increased rates of chronic bronchitis, lung cancer and heart disease as they penetrate deep into the lungs and can pass into the bloodstream.

An air quality index compiled by the US embassy in Delhi on Monday registered a PM2.5 reading of 175, which is considered unhealthy. The reading from the US embassy in Beijing was just 53, which is considered moderate.

Prime Minister Narendra Modi used Monday's conference to defend India's record on pollution, saying the country has a strong tradition of protecting the environment. "We must think of traditional ways to tackle environmental issues," he said in a speech to delegates.

"There can be green solutions in our age-old traditions," he added, suggesting that Sundays could become "cycle day" on India's traffic-clogged roads.

Though the government has yet to announce any major moves to tackle air pollution, policymakers have suggested restrictions on private vehicles, higher pollution-related taxes and stricter enforcement of urban planning laws.
