This study investigated the characteristics of heavy metals and polycyclic aromatic hydrocarbons (PAHs) in Jellanamdo soils using statistical analyses, including correlations between heavy metals and PAHs. We trimmed the four original samples from the dataset and reanalyzed the remaining 68 samples. A linear correlation (r = 0.82) was observed between Cr+6 and DahA (Dibenz(a,h)anthracene) concentration, and these compounds likely originated from automobile combustion. In general, the quantities of heavy metals and PAHs were positively and less significantly correlated. We found that BaP, BaA, DahA, and Cr+6 were important compounds in the correlation analysis. BaA, Chr and BaP were linearly correlated with each other and originate from diesel and gasoline automobile combustion.
