- Abstract
The actual and fatal concentrations of selected heavy metals, including cadmium, cobalt, copper, lead, nickel, and zinc in corals from the Gulf of Aqaba were determined. Several living coral samples of different species (e.g., Porites) were collected from shallow depths (of about 5 m) at a number of sites along the Jordanian Gulf of Aqaba coast. The coral samples were collected using either a pneumatic diamond drill corer (for Porites) or a hammer and chisel (for other branched species). Some of the corals that had been collected were analyzed for heavy metals using atomic absorption spectrometry, and other samples were used in incubation experiments. The heavy metal concentrations were determined separately in the coral skeleton and the tissue layer. Heavy metal concentrations have not previously been determined in corals from the Gulf of Aqaba. We conclude that corals are suitable for use as proxy tools for assessing environmental pollution (i.e., they are bioindicators) in the Gulf of Aqaba and the Red Sea. Therefore, this study provides useful information on the degree of heavy metal contamination in the study area.
