Abstract
Chemical emission measurements from different brands of personal computers (PCs) were conducted in a 1 m3 glass chamber. Eight PCs were tested individually. Each consisted of the same brand of PC tower and one of the 4 different brands of PC monitors. Within each brand both cathode-ray tube (CRT) and thin-film transistor (TFT) flat panel monitors were evaluated. Volatile organic compounds (VOCs) and aldehydes were quantified using GC/MS and HPLC, respectively. Compared with PCs with TFT monitors, PCs with CRT monitors had slightly higher emission rates of formaldehyde and acetaldehyde, emitted greater quantities of C3-C6 aldehydes having low odor thresholds and had higher emissions of aromatic hydrocarbons. Emission rates of aliphatic hydrocarbons were low for both PCs with CRT and TFT monitors. However, estimated concentrations of these chemicals in a normal office space based on the measured emission rates were much lower than the odour thresholds.
