Effects of ambient PM_2.5 exposure on lung function disorder in community around construction industry

Background: Previous studies have reported adverse effects of fine particulate on lung function. However, there has not been much research conducted in the construction industry area. Objective: The study was to determine the relationship between exposure of ambient PM_2.5 concentrations to lung function disorders in the ready-mix industry area. Material & Method: The research used a cross-sectional study on sample size of 100 respondents. It was divided into two regions which were determined based on the dominant wind direction. Ambient PM_2.5 concentration was measured using gravimetric method, and pulmonary function used a portable spirometry. Results: PM_2.5 concentration was obtained above the average of NAAQS provision (0.041 mg/m³). There was no significant association between lung function disorder and the average PM_2.5 concentration both site A (p=0.583) and B (p=0.321), but from smoking behavior, there was a significant association with lung function disorder. This study found no evidence to suggest that living in the area of ready-mix industry is a major determinant of lung function disorder. Further research is needed to see early indications of health effect using other chemical methods and parameters.
