Effect of Pollutants on Lung Functions of Bus Drivers(age 20-55 Years) : Effect Of Pollutants On Lung Functions Of Healthy Non Smoking Bus Drivers In The Age Group Of 20-55 Years

The present study was undertaken to establish the effect of pollutants in the form of auto exhaust, gases etc on respiratory airways of healthy non smoking bus drivers in the age group of 20-55 years, by measuring peak expiratory flow rate (PEFR) values.Results were compared with healthy non-smoking persons in the age group of 20 yrs. to 55 yrs. engaged in the works other than bus driving.Influence of age, height, weight, body surface area and duration of exposure on PEFR was studied. PEFR test was performed by using Mini Wright's Peak Flow Meter. RESULTS: Mean PEFR of bus drivers was found to be less than that of control subjects in each group and the results were found to be statistically highly significant (p
