This study used a meta-analysis approach to examine the distribution of three polycyclic aromatic hydrocarbons (Phe, Pyr and BbF) in the surface water of the world's seas as well as the factors that influence them. According to the findings, the Pacific Ocean had significantly greater concentrations of Phe, Pyr and BbF (16.885, 15.787, and 0.642ng/L) than the other oceans. These concentrations were also significantly linked with salinity, temperature, latitude, distance from coast, and chlorophyll. According to the findings, energy consumption and oceanic PAHs had a substantial and positive correlation (P<0.05). The distribution pattern of PAHs in the world's oceans is shown by this study, which offers a scientific foundation for the development of practical methods for the prevention and management of marine pollution.
