This study reports the levels, distribution, and sources of polycyclic aromatic hydrocarbons (PAHs) analyzed in surface sediment samples from Petrolifera and Porto Romano ports. They are well known for their industrial activity and good transportation. A total of 17 samples were collected from both ports in December 2023. A gas chromatography/flame ionization detector (GC/FID) was used to analyse the 13 PAHs. The total concentrations of PAHs in sediments at Petrolifera Port varied from 102.9 ng g-1 to 358.3 ng g-1, with an average value of 226.6 ng g-1. Similarly, the quantities in sediments from Porto Romano Port varied from 135 ng g-1 to 1241 ng g-1, with an average value of 556 ng g-1. Sites within the ports have the highest concentrations of PAHs. Approximately 40% of the Σ13PAHs in Petrolifera and 39% in Porto Romano were attributed to 3-ringed PAHs within the analyzed areas. About 60% of the PAHs with rings between 4 and 6 were found in Petrolifera Port, and 61% in Porto Romano Port. The isomeric diagnostic ratio showed that PAHs in surface sediments in both areas originated from both sources, but mainly dominated by pyrogenic sources. The results were compared with different sediment quality guidelines.
