Status of air quality and respiratory health in Delhi
Abstract
The paper analyses air quality trends in the city of Delhi over the decade. Pollutant levels have gone up again after a brief period of marginal decline. A review of activity levels across different contributing sectors is carried out. Vehicles have doubled in the last decade and have contributed to increase in pollutant levels. The effectiveness of interventions taken to reduce air pollutant concentrations is evaluated. There was a marginal decline of pollutants due to introduction of cleaner fuels, vehicles and other relevant measures. The effect of air pollutant concentrations is been assessed over the respiratory health in the city which also shows increase in mortalities due to respiratory disorders during the last few years. The paper finally suggests additional measures for control of air pollution in the city.
