Chronic Obstructive Pulmonary Disease (COPD), is characterized by coughing, shortness of breath, sputum production, rapid breathing, wheezing, and weight loss due to the energy required for labored breathing. COPD includes chronic bronchitis and emphysema chronic bronchitis inflammation of the lining of the bronchial tubes emphysema permanent destruction of the alveoli. Chronic respiratory diseases have a preeminent role in the health conditions of people residing near coalmine areas with implications for morbidity and excess mortality from specific causes. Atmospheric pollution from anthropogenic sources such as coal mining, industrial sources is a serious worldwide concern as it is associated with adverse health effects.The aim of this study was to find a correlation between coal dust and reductions in lung function. An environmental health survey was conducted in and around the surrounding areas of opencast coal mine, Tirap to determine the prevalence of various respiratory symptoms and to assess pulmonary function among the villagers. Although cigarette smoking is the main environmental risk factor, only about 15% of smokers develop clinically significant disease suggesting other influences on disease expression. We screened 412 individuals during surveys at the coal mine site, Assam to find out possible occurrences of COPD and associated environmental risk factors, mainly coal dust exposure. Lung function test was done with a portable spirometer. COPD was diagnosed on the basis ATS guidelines. The subjects were categorized into COPD (Smokers and NonSmokers) and NonCOPD (Smokers and NonSmokers). Air quality was monitored using Respirable Dust Sampler and analyzed for Respirable Suspended Particulate Matter (RSPM), SO2 and NO2.Coal dust exposure was a potential factor in development of COPD
