| 英文摘要 | This study focuses on road dust in Haizhou District, Lianyungang City, and analyses the content and distribution characteristics of six pollutants (Cu, Pb, Zn, Cd, Nitrogen and phosphorus pollutants) in the road dust. The study employed three evaluation methods and a health risk assessment to evaluate the risk of pollutants in road dust. Additionally, the impact of different rainfall intensities on the turbidity of initial rainwater and the release of road dust pollutants was explored, and the mechanisms of pollutant's migration and release were analysed. The results indicated that road dust contamination by Cu, Cd, and TN is more severe, with the average contents of Pb and Zn (72.11 mg/kg, 701.33 mg/kg). TP (433.75 mg/kg) is slightly below the limit set by the Canadian Department of Environment and Energy guidelines. Additionally, under simulated external disturbances, the release of pollutants (heavy metals, TN, and TP) is significantly positively correlated with the turbidity of the overlying water and significantly negatively correlated with the particle size of road dust, suggesting that different rainfall intensities affect pollutant's migration and release by influencing water turbidity and road dust particle size. This study provides theoretical support for improving the urban environmental quality. |
