The Correlation of Limestone Dust Exposure to Lung Function Impairment in Limestone Mining’s Workers, Centre Java, Indonesia

BACKGROUND: Limestone dust is produced by limestone mining activities, one of them PM2.5. Exposure PM2.5 can cause lung function impairment. AIM: The purpose this study was to determine the correlation exposure with impairment in workers. METHODS: This used a cross-sectional total sampling technique 30 instruments questionnaires for interviews, Dusttrak II TSI measure concentration and spirometry function. RESULTS: Based on results study, highest values were 987 ?g/m3 lowest 14 ?g/m3. analysis using Chi-square obtained between use personal protective equipment (p = 0.000). Furthermore, Fisher’s exact test, there pulmonary 0.002) years work CONCLUSION: Further research needed environmental health risk estimates based intake.
