The regulation investigation of the uptake, distribution, and accumulation of polycyclic aromatic hydrocarbons (PAHs) in the crop growing is essential for human health risk assessments. As an important crop with Chinese medicine homologous food function, Pueraria lobata (P. lobata) was selected as the model crop with rhizome as the products to explore the absorption, and distribution of PAHs under the natural field environment for the first time. After treated with PAHs in soil at different growth stages, the detailed PAHs in soil and tissue were analyzed. The results showed the agronomics traits of P. lobata had no obvious change after treated with PAHs, especially at the maturity stage. The accumulation of Σ
