Abstract
Tobacco use is a risk factor for many diseases, especially those affecting the heart, liver, and lungs, as well as many cancers. In 2008, the World Health Organization named tobacco as the world's single greatest cause of reventable death. Workers in the tobacco industry may experience exposure to certain environmental hazards, including tobacco leaf dust and pesticides remaining on tobacco as residues from field or post harvesting applications. As per tobacco institute of India 3.5 million people involved in tobacco industry which includes 6 million farmers, 20 million farm workers, 4.4 million beedi workers, 2.2 million tendu leaf pluckers and 2 million traders although the trade unions and private organizations says that the actual number of Tobacco workers is much higher as there are many unregistered workers in India.4 The dust of tobacco enters the respiratory system of tobacco factory workers through inhalation during tobacco processing, causes respiratory impairments.5 Workers of tobacco industries are chronically and predominantly exposed to tobacco dust and majority of workers of tobacco industries are smokers and Non-smoker tobacco workers are also exposed to passive smoking at their work places.6 In present study it was found that exposed workers show values of FEV1 lower than their predicted values and also there is statistically significant difference between exposed and unexposed subjects. FVC values in workers are found decreased and is statistically significant. Statistically significantly decreased values of PEFR are observed in tobacco workers. Significantly decreased FEV1/FVC ratio is also observed in tobacco workers. Decrease in FEV1 and PEFR shows obstructive changes in large airways.11
