| Summary: | Introduction: This cross sectional study was conducted among 33 quarry workers and 43 office workers. Objective: The aim of this research was to determine the association between the exposure to particulate matter, PMlO and respiratory health among quarry workers. Methodology: A purposive sampling method was used to choose the respondents based on the inclusive criteria such as male, age between 20 to 55 years old, at least 1 year experience as quarry workers and did not have any chronic lung disease. A set of pre-tested questionnaire which was modified from the American Thoracic Society (A TD), 1978 was used to collect information on socio¬demographic and respiratory symptoms. SKC Personal Air Sampler and Chestgraph HI-lOl Spirometer were applied to measure the concentration of PM 10 and to check the lung condition of the workers. Result: The mean PMIO concentration for exposed group was four times higher (459.39±303.29 J..lg/m3) compared to the mean PMIO concentration for comparative group (1l6.l4±9.81 J..lg/m3). There was a significant difference (z=-4.280, p< 0.001) in the exposure level of PMIO between exposed and comparative group. There was a significant difference in FYC (p=0.009), FEY] (p=0.002), FYC % predicted (p=0.004) and FEY] predicted (p=0.025) between both groups. The prevalence of respiratory symptoms for chronic cough (OR=5.79, 95% CI=1.44-23.23), chronic phlegm (OR=4.23, 95% CI=1.l9-l5.07) and chest tightness (OR=9.33, 95% CI=1.06-81.86) were significantly higher among quarry workers compared to office workers. There was no association between exposure to PMIO and lung function parameters in exposed groups. The result also showed that there was no significant association between working duration (years) and lung function parameters among exposed group (p>0.05). Conclusion: As a conclusion, there was no significant association between exposure to PMIO concentration and lung function among quarry workers.
