英文摘要Roadside soils may be affected by potential toxicity elements (TPEs) from vehicles; however, pollution status, ecological and health risks of PTEs in roadside soils were rarely reported on national scale. In this study, a dataset of PTEs in roadside soils was compiled based on the literatures published in 2000-2021, and then pollution level, ecological and health risks of PTEs were evaluated using geochemical accumulation index (I-geo), potential ecological risk index (ER), and human risk assessment coupled with Monte Carlo simulation. Driving factors of PTE accumulation in soils were determined by Geo-detector method. Results indicated that Cd exhibited moderate pollution and considerable ecological risk with the highest I-geo of 1.25 and ER of 100.1, respectively. Vehicle ownership (VP) and precipitation (PP) significantly affected accumulation of PTEs, with q values of 0.209 and 0.191 (P < 0.05), respectively. VP paired with PP enhanced nonlinearly PTE accumulation (q = 0.77). Only 6.89% and 1.54% of non-carcinogenic risks for children and adolescent exceeded the threshold of 1, respectively, whereas 93.11%, 95.67%,58.80% and 58.14% of carcinogenic risks for senior, adults, adolescent, and children surpassed 1E-06, respectively. The results of this study provided valuable implication for managers to design effective strategies for pollution prevent and risk control.
