ABSTRACT

 

The most congested area of the Bilaspur city, Gol bazar, was selected as the study site to study the effect of vehicular pollutants on the upper respiratory tract disorder. The state pollution board was requested to measure the amount of pollutants, especially SO2, NO2 and CO. The smoke density of 60-70 Hartridge smoke units is considered to be permissible smoke density in this study.The Gol bazaar lane is only 9 feet wide and most congested. Beside to this lane there are a number of houses situated very close to the road. We estimated the released Carbon Monoxide and Sulfur Dioxide from the vehicles, crossing the Gol bazaar lane. Also we collected the data regarding occurrence of upper respiratory tract disorders, especially allergic Bronchitis among the people living to the houses besides the lane. Out of 96 people interviewed for the occurrence of disease, 14 were reported as the victims of allergic Bronchitis. This rate of occurrence of disease is estimated very high in comparison to the other areas of the city. The seasonal variation of the disease was also noted, in winter when the smoke of the vehicle deposited very close to the houses due to cold, high-density air, the rate and the severity was noted high. Social factors are also important aspects of environment, so we collected data regarding feeding practices to the infants and children of that specific area. It is proved fact that top feeding practices less than one year of age is one of the strongest precipitating factors of Bronchitis. Out of 14 victims of the disease, 9 were bottle feeded babies during their infancy period. Chronic airway inflammation, mucus hyper secretion, reversible airway constriction, and bronchial hyper responsiveness are important pathogenic features of asthma. With the increased vehicle congestion, the severity of the disease and the number of victims were also observed increased. The present study concludes that the exhaust from the automobiles, congested lane and situating near- by houses along with the history of top feeding are precipitating factor for the increasing rate and severity of Allergic Bronchitis in Bilaspur city.
