Abstract

Industrial pollution has been a major factor causing the degradation of the environment around us, affecting the water we use, the air we breathe, and the soil we live on. In many developing countries air quality has deteriorated because of rising industrial activity. Puffed rice is a popular food item, which is produced in cluster of small units. Air pollution is the most serious problem in the Puffed Rice units in the form of particulate matter, carbon monoxide and other harmful airborne pollutants from tyre burning.5 So far very little data is available on extent and severity of the pollution that is caused by this cluster. Hence the present study is taken in Davangere. Objectives: To compare the lung function in terms of PEFR between the residents surrounding puffed rice industries with the residents of urban davangere and also to compare the effects with relation to duration of stay in that area Material & Methods : 65 healthy adult subjects of urban residential areas of Davangere and 61 healthy subjects of residents surrounding puffed rice industries within a radius of 500mts were selected randomly from the population of Davangere. The duration of the stay in the area is also considered to see the dose response relationship. Results:There was a drastic decrease in PEFR in residents surrounding puffed rice industries compared to the residents of urban davangere. It was also absorbed that the decrease was more in people who were residing in that area for a longer duration showing a dose response relationship. Discussion:This results because, smoking causes inflammation and narrowing of airways which results in increase in resistance to airflow and a decrease in elastic recoil pressure of the lungs. Conclusion: The actual values of PEFR are decreased in residents surrounding puffed rice industries compared to residents of urban Davangere and all the values are more decreased with increase in duration of stay in that area .The decrease in PEFR is more in the first ten year stay in this area indicating early peripheral airway narrowing and these effects worsen progressively with continued exposure.
