This article presents the results of quantitative assessment of indoor air pollutants (IAP) in the workplaces of King Fahd University of Petroleum and Minerals (KFUPM), Dhahran, Saudi Arabia. Twenty two workplaces were scheduled for four quantitative IAP measurement sessions, i.e., summer day, summer night, winter day, and winter night. The concentrations of five indoor air contaminants, i.e. formaldehyde (HCHO), carbon dioxide (CO ), carbon monoxide (CO), sulfur dioxide (SO ), and total hydrocarbons, in 2 2 addition to air temperature and relative humidity were measured and reported during each session. This was accomplished using the Bruel and Kjaer Multi-gas Monitor Type 1302. Quantitative analysis of the results show that 65% of the highest concentrations recording of all contaminants had developed during the summer day measurement in the respective locations. On the other hand, over 80% of the lowest concentrations reported for each location were detected during the winter night sessions. Day concentrations were always higher than night concentrations. Locations with higher contaminants' concentrations and causes were identified. |
