Effects of Air Pollution on the Respiratory Health in Hyderabad
A study was conducted by the Department of Zoology, Osmania University
in 1998, to assess the prevalence of thoracic problems in Hyderabad and
study the ventilatory functions in subjects belonging to three sample
areas. These, areas were designated as industrial, commercial and residential
ones.
Results : A higher prevalence, approximately 30-50% of respiratory symptoms
have been reported in the study. Chronic Bronchitis and Asthma patients
were higher in the commercial areas. Thoracic and ventilatory abnormalities
also have been reported to be higher in the commercial areas. This is
associated with the mean and peak levels of SO2 and only the peak levels
of NOx.
