Based on Positive Matrix Factorization(PMF)model,the sources and contribution rates of polycyclic aromatic hydrocarbons(PAHs)pollution in the estuarine and coastal zones of Shima River were analyzed.In April 2021(normal season)and July(wet season)to study and analysis of surface water and the surface sediment samples collected respectively,the results showed that the main sources of PAHs pollution in the study area including oil leakage,coal burning,transportation and biomass combustion,etc.,of which the transportation source has contributed more than 60％of PAHs in the sediments in the study area;the total contribution rate of transportation and coal combustion sources to PAHs in surface water is close to 80％;the total contribution rate of PAHs in suspended particles from oil spill and transportation sources is close to 70％.The results can provide some basis for the green development of water resources and the treatment of PAHs pollution in Shima River area.
