Abstract: A study was carried out in order to study and characterize chemically the natural forests of mangrove ecosystems (Avicennia marina) along the shoreline of the United Arab Emirates. The results for the hydrochemical parameters like salinity, pH, DO, BOD, and nutrient salts revealed higher values and more pronounced variations in the mangrove water compared to nearby creeks indicating decreasing trend. Among mangrove areas, Umma al-Quwain is characterized by its higher dissolved oxygen, pH, phosphate, and lower BOD. ammonia and nitrate. The mangrove water of Khor al-Khuwair was characterized by its higher salinity BOD, ammonia, nitrite, nitrate, and silicate and lower dissovled oxygen, pH, and phosphate. The results for petroleum hydrocarbons in mangrove water indicated the presence of hydrocarbons in all samples. However, the mean hydrocarbons concentration in seawater (3.9μg/l) was almost similar to the concentrations in the coastal water of the Arabian Gulf, clearly revealing the absence of high concentrations. Sediment analysis for organic carbon contents indicated higher values in mangrove sediments (1.1-2.8 times) than the nearby creeks. The results showed that all values were below 10 μg/g of dry weight which correspond to hydrocarbons concentrations in coastal areas considered unpolluted.
