Background and Aim: The presence of oil installations, wharves and refineries in the coastal strip of Bandar Abbas causes the release of a large amount of oil pollutants that eventually reach the sediments and cause bioaccumulation in the macrobenthic communities that live in the sediments. A ring in the sediments and their comparison in the tissue of four groups of macrobenthic communities, including gastropods, bivalves, crustaceans, and paraterans, were made in the waters around Bandar Abbas.
Methods: To measure the concentration of polycyclic aromatic Hydrocarbon in the sediments and macrobenthic communities present in it, sampling was done at 9 stations using a Grab Van Veen device along the coastline of Bandar Abbas in March 2018 and March 2019.
Results: The mean concentration of total PAHs by station showed that the refinery has the highest concentration of these compounds, followed by Posht-e-Shahr and Soro. The highest average concentration of polycyclic aromatic hydrocarbons in gastropods belonged to the 3-ring compound Acenaphthene with an average (ppb) of 1117 and the lowest value belonged to the 6-ring compound Benzopyrylene with an average (ppb) of 2. In bivalves, the highest average concentration of the 3-ring compound Acenaphthene with an average (ppb) of 1261 and the lowest value of the 6-ring compound Benzopyrylene with an average (ppb) of 32 were obtained. The highest average concentration of the 4-ring compound Fluranthene with an average (ppb) of 1551 and the lowest value of the 6-ring compound Benzopyrylene with an average (ppb) of 0 was obtained in crustacean tissue.
Conclusion: Findings have shown that sediments absorb 5-ring compounds, molluscs absorb 3-ring compounds, crabs absorb 4-ring compounds, and reptiles absorb 5-ring compounds more easily. |
