Air pollution in Calcutta elicits adverse pulmonary reaction in children

Pulmonary responses of children chronically exposed to ambient air pollution in Calcutta have been investigated. A total number of 153 children from Calcutta and 116 from rural West Bengal in the age group of 6-17 yr were included in this study. Respiratory symptom complex, sputum cytology and micronucleus (MN) count of buccal epithelial cells were evaluated.
