| Abstract: | This study investigated the distribution, sources, and ecological toxicity of polycyclic aromatic hydrocarbons (PAHs) in surface sediments along the Mekong River, from its entry into Vietnam to its outflow into the East Sea. The results showed that total PAH concentrations ranged from 53.66 to 1205.35 ng/g dry weight, with an average of 281.08 ± 391.13 ng/g dry weight. Among the 16 PAH compounds analysed, Pyrene (Pyr) and Fluoranthene (Flu) were detected in all sediment samples. Naphthalene (Nap) had the highest concentration among the detected PAHs. Diagnostic ratio and principal component analyses indicated that PAHs originated from mixed sources, including traffic emissions, coal and biomass combustion, petroleum leakage, and wastewater discharge. Based on the risk quotient (RQ), PAHs posed low to moderate ecological risks. Both adults and children in the study area may be exposed to cancer risks due to the presence of carcinogenic PAHs in sediment samples.; (© 2025.
