  • Analysis of soil samples revealed mean PAH levels ranging from 1.22E−02 ± 0.00 to 5.60E−02 ± 0.01 mg/kg, with higher PAH concentrations observed at 0–10 cm compared to other depths. The sum of PAHs (∑PAHs) ranged from 1.58E−01 to 6.71E−01 mg/kg, as the sum of low molecular weight PAHs (∑LPAHs) varied from 7.16E−03 to 1–1.60E−01 mg/kg, while the sum of high molecular weight PAHs (∑HPAHs) ranged from 1.81E−02 to 5.42E−01 mg/kg. The sum of carcinogenic PAHs (∑Carcino-PAHs) varied from 5.39E−01 to 9.74E−02 mg/kg, indicating elevated levels of carcinogens in the sampled soils. Diagnostic ratio, principal component, and correlation analysis of the results revealed that pyrogenic sources wer...
