The World Health Organization (WHO) recently tightened Air Quality Guidelines (AQGs) of 24 h averaged PM2.5 as 15 μg/m3 as against India’s National Ambient Air Quality Standards of 60 μg/m3. This issue is widely debated in Indian media to build a pressure that Indian should revisit its AQI in the light of AQGs of WHO. A recent research based on 4 major Indian cities indicates that even baseline levels exceed the corresponding AQG levels. This led to the conclusion that circumstances do not warrant an immediate review of India’s NAAQS which appears to be adequate. It is stressed that a comprehensive air quality forecasting framework like SAFAR needs to be developed for other cities in India. The work related to impact of ambient air pollution on public health are limited in India and most studies apply exposure-response function applicable to western countries in absence of our own. Therefore, scientific studies must be undertaken to determine the “exposure-response function” and the susceptibility of Indians to different air-pollution related diseases.

摘要

The World Health Organization (WHO) recently tightened Air Quality Guidelines (AQGs) of 24 h averaged PM2.5 as 15 μg/m3 as against India’s National Ambient Air Quality Standards of 60 μg/m3. This issue is widely debated in Indian media to build a pressure that Indian should revisit its AQI in the light of AQGs of WHO. A recent research based on 4 major Indian cities indicates that even baseline levels exceed the corresponding AQG levels. This led to the conclusion that circumstances do not warrant an immediate review of India’s NAAQS which appears to be adequate. It is stressed that a comprehensive air quality forecasting framework like SAFAR needs to be developed for other cities in India. The work related to impact of ambient air pollution on public health are limited in India and most studies apply exposure-response function applicable to western countries in absence of our own. Therefore, scientific studies must be undertaken to determine the “exposure-response function” and the susceptibility of Indians to different air-pollution related diseases.
