This study revealed the analysis of Fe content in the coral reef of Prigi Coast to monitor its waters as an environmental biomonitoring agent. Fe can accumulate into the coral structure through food, the mucous tissue, the mesenterium filament, and calcium element substitution that built-in the each of Fe coral fractions. Fe can be leached in the coral reef fractions using the Tessier-microwave method. Tessier microwave method divided of Fe in the ion exchange (fraction 1), carbonate bound (fraction 2), reduction (fraction 3), oxidation (fraction 4) and residual (fraction 5), respectively. The Tessier-microwave method results detected of Fe in the fraction 3 only, indicated that all of the Fe in the coral reefs was bound to the reduction fraction. The Fe content in the fraction 3 at 6 selected locations of Prigi Coast was 127.10 ppm, 39.12 ppm, 56.64 ppm, 78.10 ppm, 11.46 ppm, and 47.62 ppm, respectively. According to several calculations of CF, PLI and Igeo indexes, it indicated the contaminated of Fe in the coral reefs, especially at reduction fraction. © Published under licence by IOP Publishing Ltd.
