The main objective of the air quality index (AQI) system is to interpret air quality in a standardized indicator to enable the public to understand the likely health and environmental impacts of air pollutant concentration levels monitored on any given day. The daily averaged concentration data of air pollutants of monitoring sites under the National Ambient Air Quality Monitoring Programme of Delhi were analysed for the period 2001-2010 using the AQI system. This study was undertaken to (i) evaluate the trends of air quality for the past 10 years, (ii) ascertain the association of air quality with mortality and respiratory morbidity rate of Delhi, and (iii) examine the seasonal variation of air quality. The air quality status was found to be varying from 'moderate' to 'unhealthy for sensitive group' category from the health impact point of view. Non-trauma mortality (r = 0.877, P < 0.01) as well as respiratory morbidity were found to be significantly correlated with AQI values. The present study increases public awareness of the health implications of air pollution and helps assess pollution trends in a more meaningful way.Keywords

Metro cities across the world use air quality index (AQI) as a tool for local air quality management. The basic purpose of the AQI system is to interpret the air quality status based on potential human health impacts. In the air quality indexing system, ranges of air pollutant concentration are characterized into different categories of air quality on the basis of health implication criteria. Standardized public health advisories are used for different categories of air quality for general public awareness. AQI values at the regional level are normally reported in the media to enhance public access and awareness. In the present study, air quality of Delhi, India has been interpreted, and seasonal and spatial deviation of air quality mapped to enable health risk communication. We also highlight the linkage of air quality with daily nontrauma mortality rate. A significant correlation of air quality with daily non-trauma death rate was observed. The female population was found to be more vulnerable to poor air quality in comparison to the males. Among the different age groups, maximum vulnerability was observed for the population aged 65 years and above. Average air quality status of Delhi was observed at a level which can cause breathing uneasiness to those with respiratory comorbidities, as well as for children and aged people. Direct linkages of different air pollutants with associated health impact estimates have been worked out by several researchers in the past. The present study evaluates the effect estimates on daily non-trauma mortality values with AQI levels. The findings of this study are consistent with earlier reports and provide additional evidence for health impact linked to poor air quality.Keywords
