Air pollution problems due to the emission of air pollutants from the various industrial facilities become serious issues and a lot of air pollution processes have been developed. The objective of this study is to investigate the hazardous air pollutants in various solid waste incinerator. The emission properties of air pollutants and heavy metals for the three types incinerators(small/medium/large scale) were analyzed with box plot which is graph data as a box representing statistical values. The box plot analysis was based on the data contained in several literatures and our determination results at three types incinerators. Thus. the results could be summarized as follows; In the case of the small scale incinerators, most of the incinerators were equipped with cyclone for dust removal and incomplete combustion. Based on the 25th percentile and 75th percentile in the box plot, it was revealed that the concentration of SO₂, CI₂, CO, and dust were exceeded the new stringent emission standards(start in 2006). The results of heavy metal analysis showed that the concentrations of Pb, Cu, and Cd were satisfied to the current or future emission standards, whereas Cr, Zn and Ni exceeded the emission standards. For the medium scale and large scale incinerators. most of the air pollutants and heavy metals were satisfied to the current or future emission standards except dioxin, CO and dust in the medium scale incinerator. In order to meet the stringent emission standards in the near future. it is need to install an air pollutants control devices. to enact an intensified management standard. to make a special law to control small and medium incinerators. and to closedown an old facilities.
