The aim of study was to investigate polluted amounts 16 PAHs in railroad(waste railway ties) area, factory area and land-fill area. All of the samples were analyzed by GC-MSD(SIM mode), and the recovery range, detection limit and standard deviation obtained by this experiment were 73.88 ~ 94.75%, 0.009 ~ 2.252 ${\mu}g$/kg and 1.861 ~ 12.373, respectively. The concentrations of total PAHs(t-PAHs) and total carcinogenic PAHs(t-PAHcarc) in soils of three area were in the range of 12.54 ~ 3274.95 ${\mu}g$/kg on a wet weight basis with a mean value of 499.8 ${\mu}g$/kg and 0 ~122.77 ${\mu}g$/kg with a mean value of 20.16 ${\mu}g$/kg, respectively. The correlation between t-PAHs and t-PAHcarc appeared very high in railroad(waste railway ties) area ($R^2$ = 0.8301), factory area ($R^2$ = 0.9217) except land-fill area($R^2$ = 0.3782), indicated that t-PAHcarc concentration increases in proportion with t-PAHs.
