ABSTRACT

Background: Cement is one of the most important building materials in the world. Ex­po­sure to cement dust has been demonstrated to have adverse effects on human health. Several cross-sec­tional studies have reported reduction in lung function in wor­kers expos­ed to high con­cen­trations of cement plant dust. This study aimed to examine the effect of emission Tonasa cement fac­tory on lung capacity of people living in the area around the cement industry.

Subjects and Method: This was a cross sectional study conducted at South Konawe, Ken­dari, South East Sulawesi. A total sample of 241 respondents in four different loca­tions was selected for this study. The locations were based on wind directions and within 3 kms from the cement in­dus­try. The dependent variable was lung capacity. The independent varia­ble was outdoor am­bient air. The data of the emission dispertion from the cement fact­ory stack was collected by AER­­­MOD. The instrument to measure lung capacity was spiro­metry analyzer. The data were ana­lyzed by Chi Square.

Results: The distribution of the emission could reach 1.5-3 kms with the concentration of CO= 20,000 µg/m3, NO2 = 100 µg/m3, SO2 = 40 µg/m3, TSP = 210 µg/m3. The con­di­tion of society lung capacity (FEV1 and FVC) had a relationship with the ambient air qu­ality (p<0.001).

Conclusion: The condition of society lung capacity is significantly associated with high cement dust exposure. Preventive measures are needed to reduce the dust exposure.
