“…The increase of metal concentration in the Porites coral of Ambon Bay thus might be related to the increased of anthropogenic disturbance including urban waste and industrial activities around the bay. The similar trend were reported previously in coral from other areas such as Gulf of Aqaba, Jordan [25]; Sabah, Malaysia [26]; Bermuda, North Atlantic Ocean, central Indian Ocean including Chagos Archipelago, western Sumatra, and Strait of Singapore [27].…”

The concentration of metals in coral represents environmental changes, monsoonal variation, and human disturbance. Metals in coral were used as a proxy to evaluate the response of coastal areas to climatic and human stresses. In this study, several metals including lead (Pb), cadmium (Cd), chromium (Cr) and zinc (Zn) in Porites coral taken from Ambon Bay, Ambon Island, Indonesia, were investigated. The history of metals transient in the most populated island in Maluku Province is documented here from measurements of metals concentration from monthly-banded coral that grew in coastal seawater from 2001 to 2009. The concentration of heavy metals in coral samples was measured using Flame Atomic Adsorption Spectrophotometry (FAAS) method. The results showed metals bioaccumulation (average ± STD) were following decreasing order: Pb (0.96 ± 1.58 μg/g) > Cr (0.15 ± 0.34 μg/g)> Zn (0.11 ± 0.26 μg/g) > Cd (0.007 ± 0.016 μg/g). Moreover, all metals content in the coral showed a remarkable rose from 2001 to 2009 and showed relatively high concentrations during the southeast monsoon for Pb and Cd. Based on the statistical analysis, all metals in Ambon Bay coral were impacted by terrestrial input. In addition, Pb and Cd were also impacted by natural processes that may be associated with their biogeochemical cycle and monsoonal variation.

“…Beberapa kronologi karang Scleractinia seperti Porites telah mampu mendeteksi perubahan lingkungan dengan skala waktu yang singkat melalui skeletonnya (Shen et al, 1987;Shen dan Boyle, 1988;Guzman dan Jimenez, 1992;David, 2003). Jenis karang ini memiliki annual banding yang terlihat lebih jelas sehingga memudahkan saat proses analisis lingkaran tahunannya (Chen et al, 2010;Mokhtar et al, 2012).…”

Coral is one of marine organisms that can accumulate heavy metals such as Pb in its skeleton. The purpose of this study was to determine the concentration of heavy metals I. PENDAHULUANLaut merupakan tempat bermuaranya aliran air dari daratan. Hal ini menjadikan laut sebagai tempat terkumpulnya berbagai zat pencemar yang dibawa oleh aliran air. Limbah-limbah ini terbawa ke laut dan selanjutnya mencemari laut (Yanney, 2001). Logam berat merupakan salah satu unsur pencemar perairan yang bersifat toksik dan harus terus diwaspadai keberadaaannya. Pencemaran logam berat dapat menyebabkan terjadinya perubahan struktur komunitas perairan

“…Indeed, different studies have shown how trace elements in corals can be used as indicators of the origin and the growing habitat and for long‐lived samples also as proxy tools to reconstruct sea water temperature, pH changes and nutrient availability over long periods of time . Indeed, since several elements, such as toxic metals, can substitute Ca in the calcitic structure of the skeleton or can be associated with particulate organic matter within skeletal pores, the analysis of trace element composition allows to monitor the metal loads in marine environment …”

“…[16] Indeed, since several elements, such as toxic metals, can substitute Ca in the calcitic structure of the skeleton or can be associated with particulate organic matter within skeletal pores, the analysis of trace element composition allows to monitor the metal loads in marine environment. [17,18] From the historical perspective, precious corals are well known since the antiquity for their beauty and valued for the mysterious powers often attributed to their skeleton, especially the bright red ones. [19] Far from being close to extinction, a decline in shallow-water populations of this widespread taxon has been anyway observed and some concerns about its management have been raised and debated.…”

Precious coral non‐destructive characterization by Raman and XRF spectroscopy

et al. 2016

Precious corals are some of the most valuable living marine resources, growing and commercially exploited only in limited areas of the world, namely the Mediterranean Sea and the Northern Pacific Ocean. Their skeleton is formed by calcium carbonate crystallized in the form of calcite whereas their color is because of the presence of partially demethylated polyene pigments. Recently, Pacific corals have been included in the appendix II of CITES list, while Mediterranean corals are still excluded. Different Corallium species of Corallidae family (e.g. Corallium rubrum, Corallium elatius and Corallium secundum) collected from different locations of the Mediterranean Sea and the Pacific Ocean were analyzed by Raman spectroscopy for the characterization of the reddish pigment and by X‐ray fluorescence (XRF) for the determination of the chemical composition of their skeletons, in order to obtain molecular and elemental data with two relatively easy and non‐destructive techniques, which can be used quite steadily for authentication purposes. Raman analysis demonstrated the presence of specific vibrational bands useful to identify the colored pigments as a mixture involving methylated and demethylated polyenes such as carotenoids and parrodienes, characterized by the presence of ―CH3 groups along the polyene chain. The ratio between the Raman signal and fluorescence background was found to vary as a function of the macroscopic color of the coral, but Raman analyses resulted inadequate for distinguishing between corals having similar color but different origins. On the other side, XRF data provided reliable information for an appropriate separation between Pacific and Mediterranean corals at the elemental level. The results of this study will be of great relevance for the authentication and identification of the origin of corals in trade market by means of completely non‐destructive techniques.
