Study on ambient air quality, respiratory symptoms and lung function of children in Delhi
Epidemiological studies have established a close relationship between exposure to ambient air pollution and morbidity and mortality from cardio-pulmonary diseases. Air pollution is a complex mixture of various gases, particulates, hydrocarbons, and transition metals. Of all these pollutants, the association between air pollution and adverse health conditions was the strongest and most consistent for respirable suspended particulate matters (RSPM) with an aerodynamic diameter of less than 10 micrometer (PM10). Health risk from particulate pollution is especially high for some susceptible groups such as the children and the elderly persons, and those with diseases of the heart and lungs. Central Pollution Control Board had sponsored the epidemiological studiy ‘Study on Ambient Air Quality, Respiratory Symptoms and Lung Function of Children in Delhi’ carried out during March 2003–August 2005 and conducted by Chittranjan National Cancer Institute, Kolkata.
