Bioaccumulation of Heavy Metals (Pb, Fe & Zn) in the Tissues of Skeletal Coral family, Faviidae and Surrounding Sediments in the South of Qeshm Island-The Persian Gulf

The following research was conducted to study the concentration of Pb, Fe & Zn in skeletons and sediments of dominant hard coral family (Faviidae) in Zeyton Park, Naz Islands and Shib-deraz stations, South of Qeshm Island. The analysis of these heavy metals in digested samples of skeletons and sediments was done using graphite furnace Atomic Absorbtion Spectophotometry for measuring the levels of Pb and Flame Atomic Absorbtion Spectophotometry for measuring the levels of Fe & Zn. The results indicated that there are significant statistical differences toward concentration of Pb and Zn in skeletons of coral family (Faviidae) among Zeyton Park, Naz Islands Shib-deraz stations (P<0.01). There are not significant statistical differences toward concentration of Fe in skeletons of coral family (Faviidae) among Zeyton Park, Naz Islands Shib-deraz stations (P<0.01). In addition, considering the concentration of Pb and Fe in sediments of coral family (Faviidae) there are significant differences between Zeyton Park, Naz Islands and Shib-deraz stations (P<0.01 and P<0.05, respectively). So, the result of this research suggested that corals can be suggested as a pollution biomonitor.
