| Abstract: | This research investigated the levels of 16 trace and heavy elements in seawater for the first time in the northern Gulf of Aqaba. The concentrations of four selected sites along the Jordanian coast. The elements were determined by using Inductively Coupled Plasma Mass Spectroscopy (ICP-MS). Observed concentrations of Co, Cu, Ni, and Zn in seawater were higher than the threshold levels that were recommended by the Australian Water Quality Guidelines. The levels of As and Se in seawater were also higher than previously reported values from Arab seas. Moreover, it could be concluded that the Gulf of Aqaba (Jordanian coast) is highly contaminated by Ni, due to seawater concentrations exceeding both Australian and US EPA guidelines. Based on the results of this study, additional investigations are necessary to determine the anthropogenic activities that may cause this pollution. The determination of elemental concentrations in biota and sediment is also highly recommended for the Jordanian coast. This study and future studies will be useful for assessment and monitoring of marine pollution in the Gulf of Aqaba. |
