(1) Background: Polycyclic aromatic hydrocarbons (PAHs) are important components of petroleum and pose a serious threat to the soil environment oil production well sites. Therefore, scientific risk thresholds ecological assessment methods must be established for PAHs in petroleum-contaminated soils. (2) Methods: In this study, based on environmental DNA (eDNA) method, bacterial community was considered as receptor assess risks PAH contamination aged petroleum-polluted A combination quotient equivalent toxicity factor used PAHs. (3) Results: dose-response curve plotted determine 50% effective concentration (EC50) total 16 (∑TEQBaP) Following plot species sensitivity distribution (SSD) curve, hazardous protecting 95% values (HC5) (TPHs), electrical conductivity (EC), were calculated 892.1 μs·cm-1, 149.9 mg·kg-1, 0.2601 respectively.
