THE CORRELATION BETWEEN THE CO EXPOSURE TOWARDS COHB LEVEL AND THE VITAL LUNG CAPACITY OF THE PARKING ATTENDANTS AROUND SETIABUDI STREET OF SEMARANG CITY
Background: The data from WHO in 2012 shows that approximately 7 million people were reportedly died due to the exposure to air pollution. The CO gas released from the exhaust will remain in the air. If inhaled by the human, it will enter the respiratory tract and into the lungs. The Threshold Score of CO in the working place is 25 ppm by which the concentration of CO in the inhaled air is for 8 hours per day. The concentration threshold of COHB within the blood is 0,2% - 1%.
Materials and Methods: This research used a cross-sectional approach since the independent variable and dependent variable was measured simultaneously. The data were obtained from the questionnaire. Moreover, this research also measures the CO exposure of the parking attendants and the level of CO within the blood (COHb) as well as the vital lung capacity of the parking attendants.
Result: The result of the statistical test using Chi-Square shows that the CO exposure and the level of COHB have the significance of 0,643 (p>α=0,05), while the exposure of CO and the vital capacity of the lungs have the significance of 0,019 (p<α=0,05). The result of the statistical test using Chi-Square shows that the significant level of CO exposure with the COHB is 0,643 (p>α=0,05), while the vital lung capacity is 0,019 (p<α=0,05).
Conclusion: The exposure of CO has no correlation with the level of COHB, while it has the correlation with the vital capacity of the lungs.Keywords: Exposure of CO, Level of COHb and the Vital Lung Capacity
