Total suspended particulates and concentration of polycyclic aromatic hydrocarbons were measured from April 1992 to January 1993 for analyzing air pollution comparatively in five designated areas in Chonju city: industrial, semi-industrial, commercial, residential, and green area. The concentration o total suspended particulates was estimated up to 201 ㎍ in whole city level. Sixteen polycyclic aromatic hydrocarbons were commonly distributed in the city, especially the concentration greatly increased during the winter. Benzo(ghi)perylene was a major pollutant detected from 0.98 to 1.67ng/㎥ in four tested regions except the green area, in which 0.57 ng/㎥ of fluoranthene was the highest. Benzo(a)pyrene, chrysene, benzo(b)fluoranthene, indeno(1,2,3-cd)pyrene, and dibenz(ah)anthracene known as carcinogenic materials were also included in the samples analyzed. Degree of air pollution determined by total polycyclic aromatic hydrocarbons decreased in the order of 7.80 mg/㎥(commercial) > 7.72ng/㎥(industrial) > 5.71 ng/㎥(semi-industrial) > 4.72 ng/㎥(residential) > 3.21 ng/㎥(green area). Most polycyclic aromatic hydrocarbons were produced from liquid fuel. It is expected that air pollution will increase gradually as consumption of liquid fuel use increases.
