INDORE: According to Global Burden of Disease (GBD) count, a global initiative involving the World Health Organisation, in

, air pollution is ranked as the sixth most dangerous killer. Around 65 per cent of the air pollution deaths occur in Asia and close to quarter of this in India.

Reacting to the findings Centre for Science and Environment (CSE) says air pollution has become one of the top 10 killers in the world.

Anumita Roychowdhury, CSE's executive director-research and advocacy and head of its air pollution unit said, "This GBD count on air pollution and its health risks must trigger urgent, aggressive and most stringent action in India to curb air pollution to protect public health. India cannot afford to enhance health risk at a time when much of its economic growth and motorization are yet to happen."

The latest GBD results have been produced by a rigorous scientific process involving over 450 global experts and partner institutions including the Institute of Health Metrics and Evaluation, the

, the University of Queensland, Australia,

, Harvard University and the Health Effects Institute.

Elaborating about the findings she said death due to outdoor air pollution has increased significantly. According to the latest tally, air pollution causes 3.2 million deaths worldwide. This has increased from 800,000, last estimated by GBD in the year 2000 - a whopping 300 per cent increase. In the year 2000, GBD assessments had reported a much smaller air pollution-related burden of disease. The new estimates of particulate air pollution are based on ground-level measurements, satellite remote sensing and global chemical transport models to capture population exposure.

In South Asia, air pollution has been ranked just below blood pressure, tobacco smoking, indoor air pollution, poor intake of fruits and diabetes. This is scary as outdoor air pollution is a leveler that makes everyone - rich and the poor -- vulnerable.

Two-thirds of the death burden from outdoor air pollution occurs in developing Asia including India: The new GBD estimates over 2.1 million premature deaths and 52 million years of healthy life lost in 2010 due to fine particle air pollution in Asia, which is two-thirds of the burden worldwide. Killer outdoor air contributes to 1.2 million deaths in East Asia which is in throes of high level of economic growth and motorization and 712,000 deaths in South Asia (including India) which is at the take-off stage. This is much higher than the combined toll of 400,000 in EU 27, Eastern Europe, and Russia.

Roychowdhury said, "Days of doubts and complacency are over. There is hard enough evidence now to act urgently to reduce the public health risks to all, particularly the children, elderly, and poor. No one can escape toxic air. India will have to take aggressive action to reverse the trend of short term respiratory and cardiac effects as well as the long term cancer and other metabolic and cellular effects. Remember - toxic effects like cancer surface after a long latency period. Therefore, exposure to air pollution will have to be reduced today to reduce the burden of dieses."
