RELATIONSHIP BETWEEN PM10 EXPOSURE AND LUNG DYSFUNCTION IN THE WORKERS OF RICE MILL, DELI SERDANG, IN 2019
Background: PM10 is solid air particles with diameter of less than 10 micrometer which can penetrate thorax in the pulmonary system. They can stay in lungs with diameter from two to five microns. Coughing, dyspnea, and pain in chest are health disorder undergone by the workers caused by PM10.
Materials and Methods: The research used analytic survey method with cross section design. The samples were 30 workers.
Result: The result of the research showed that PM10 content in the rice mill was high (1,24 mg/m2) at the grinding point and 1,44 mg/m2 at the drying point. There was the relationship of the length of service (p-value=0,024; p<0,05), the use of PPE (Personal Protective Equipment) (p-value=0,004; p<0,05), and PM10 content (p-value=0,001, p<0,05) with lung dysfunction. The variable which had the most dominant influence was PM10 content at the probability value of 84,10%.
Conclusion: The exposure of PM10 content had the most significant influence on lung dysfunction in the workers of rice mill, Deli Serdang Regency at Exp(β)=24 which indicated that workers who worked in a location with high PM10 concentration had 24 times of the possibility to be affected by lung dysfunction, compared with those who worked in a location with low PM10 concentration.
