Inhalation of BiomassFumes over a long time leads to proliferation and fibrotic changes in Lungs. Early recognition of this damage provide, an important clue to insure good health. Spirometry is an invaluable screening test to identify patient with air flow obstruction. The study has been conducted as 100 Rural and 100 Urban Punjabi females using Biomass fuel and LPG respectively between 20-50 years of age. The ventilatory tests like PEFR, FEV measured by computerized spirometer (Med-Spiror) showeda highly significant decline in Rural women,While in rest of the parameters there is statistically non-significant decrease in rural women. The cause of decrease in the flow volume in the rural women using Bio-mass fuel is due to respirable suspended Particulate matter like So2, No2, Co2, CO etc. Which lead to decreased lung function and increased prevalence of chronic bronchitis and COPD. The cause of better preserved lung function in urban women is due to use of other fuels for cooking i.e.,LPG gas and well ventilated homes and because of non exposure to indoor pollution as in case of using biomass fuels. So chronic Exposure to biomass smoke is associated with chronic bronchitis and reduced lung function in rural women.
