Abstract
In order to devise a simplified monitoring method of dioxins, the concentrations of chlorobenzens (CBz), chlorophenols (CPh) and carbon monoxide (CO) were compared to the concentration of dioxins. The concentrations of CBz and CPh, that are dioxin analogues, were approximately correlated to one of dioxins, and therefore it was considered to be efficient in monitoring dioxins for small size incinerator. A significant positive correlation (n=12, r=0.845, p<0. 01) was also found between concentrations of CO and dioxins at early time from ignition, indicating that indirectly measurement of CO by using smoke tester is useful to see if burning at early time from ignition is good or not.
