Abstract

Indoor air quality (IAQ) has been the object of several studies due to its adverse health effects on humans. The rate of death and disease related to poor indoor air quality is very high and one of the significant threats to human health. Research on indoor air quality and its relation to respiratory health is essential to identify general symptoms related to indoor air pollutants and reduce the risk of respiratory health problems. A cross-sectional comparative study was carried out among academic staff in the Faculty of Mechanical and Manufacturing Engineering Technology, Univesity Teknikal Malaysia Melaka. The aim of the study was to determine indoor air quality and its association with respiratory health. A questionnaire was used to obtain an exposure history and respiratory symptoms of JTKM academic staff. The IAQ parameters obtained include the indoor concentration of particulate matter (PM), volatile organic compounds (VOCs), carbon dioxide (CO2), temperature, and relative humidity (RH). The mean for PM2.5 on the first floor (0.0063 ± 0.0055) is higher than on the ground floor (0.0008 ± 0.0008). Results show there is significant association between the concentration of PM2.5 on the ground floor and first floor (P = 0.014) but not for CO2, VOCs, temperature, and relative humidity. The ground floor has higher concentration of CO2, and TVOC compared to first floor. However, the value of temperature and relative humidity is higher on first floor compared to ground floor. The statistical analysis cannot be done to associate the indoor air quality with respiratory symptom among academic staff due to limitiation on the data and research.
