To provide baseline information for the marine ecosystem of Hormozgan province, the distribution of
petroleum hydrocarbons was evaluated in 52 stations involved in the mangrove and coastline ecosystem.
Coastline sampling sites included areas facing harbor, river, domestic and industrial discharge. Sediment
samples were analyzed based on ultraviolet fluorescence spectroscopy. Petroleum hydrocarbons showed
narrow variations ranging from non-detectable (ND) to 1.71 and from 0.2 to 0.63 lg/g dry weight for
coastline and mangrove sediments, respectively. The detected concentrations for total petroleum hydrocarbons
were lower than guideline values for ecological risk. Furthermore, the minimum environmental
risk was confirmed by background levels for the Persian Gulf, the Sea of Oman, and detected values for
reference areas. The results were regarded as background data in the studied area, and, considering
the rapid expansion of activities related to the petroleum industry in Hormozgan province, the continuous
monitoring of pollutants is recommended.
