The contents of benzo(a)pyrene (Bap.), Pyrene(Py) and Perylene(Pery) were determined by one-dimensional dual band thinlayer chromatogragphy and spectrofluorophotometer in soil samples from road at 36 places of Ulsan and 6 places of Seoul from April to May, 1984. The concents were as follows: 1. Ulsan city : Bap. 0.05-3.66 $\mu$g/g ; mean 1.07 $\mu$g/g Py. 0.60-11.01 $\mu$g/g ; mean 4.34 $\mu$g/g Pery. 0.94-5.48 $\mu$g/g ; mean 1.83 $\mu$g/g 1) Industrial area : Bap. 0.03-3.66 $\mu$g/g ; mean 5.28 $\mu$g/g Py. 2.34-9.07 $\mu$g/g ; mean 5.28 $\mu$g/g Pery. 1.01-3.69 $\mu$g/g ; mean 2.09 $\mu$g/g 2) Commercial area : Bap. 0.15-2.27 $\mu$g/g ; mean 0.29 $\mu$g/g Py. 0.06-11.0 $\mu$g/g ; mean 4.04 $\mu$g/g Pery. 1.03-5.48 $\mu$g/g ; mean 1.84 $\mu$g/g 3) Residential area : Bap. 0.05-0.05 $\mu$g/g ; mean 0.29 $\mu$g/g Py. 1.34-5.53 $\mu$g/g ; mean 2.74 $\mu$g/g Pery. 0.94-2.15 $\mu$g/g ; mean 1.18 $\mu$g/g 2. Commerical area in Seoul : Bap. 0.35-1.01 $\mu$g/g ; mean 0.74 $\mu$g/g Py. 9.37-24,44 $\mu$g/g ; mean 18.64 $\mu$g/g Peay. 1.47-2.24 $\mu$g/g ; mean 1.87 $\mu$g/g 3. The areas that had high contents of Benzo(a)pyrene had also high contents of Pyrene and Perylene. 4. The industrial area had the highest contents of polynuclear aromatic hydrocarbons, followed by commercial area and residential area. 5. The contents of Bap. and Pery. in the commercial area were similar in Seoul and Ulsan, while the content of Py. in Seoul was 4 times higher than in Ulsan.
