In a written reply in Rajya Sabha, Environment Minister Prakash Javadekar said that polluted air, particularly the respirable particulate matter is one of the several factors responsible for morbidity and premature deaths.
"An international study released recently has claimed that foul air is killing up to 80 people a day in Delhi. The numbers of premature deaths given in the study are based on the constructive estimates and extrapolations of data," the Minister said.
He said that government had sponsored two studies in Delhi, 'Epidemiological Study on Effects of Air Pollution on Human Health in Delhi' during 2002-2005 and 'Study on Ambient Air Quality, Respiratory Symptoms and Lung Function of Children in Delhi' which was carried out during 2003-2005.
"The studies indicate that several pulmonary and systemic immunity and damage to chromosomes and DNA and other health impairments are associated with cumulative exposure to high level of particulate pollution that increases the risk of various diseases including respiratory and cardiovascular diseases," Javadekar said.
