The chemical and physical parameters as indicator of office air quality at PT X coal mining company

Abstract

Background: Coal still ranks the second largest source of total global energy demand, which is complemented by the high-risk nature of coal mining activity. Therefore, it is important to discuss the health issues of coal workers. One of the risks associated with coal mining activities is poor indoor air quality (IAQ) due to the high concentration of airborne pollutants. Methods: This study aims to evaluate the results of air quality measurements in the PT X office, and the method used was a descriptive approach with quantitative secondary data. Furthermore, the measured variables are NO2, SO2, CO2, CO, Pb, PM10, temperature, humidity, and noise. Conclusion: The results showed that there was an IAQ problem, namely noise, temperature, and humidity which exceed the recommendations. Therefore, the IAQ management implemented by PT X was still systematically and comprehensively developing.
