Abstract

The aim of this investigation is to estimate metal concentration distribution, Pb, Cd, Zn, and Cr, in Callispongia sp, sediment, and water column in Hative waters of Ambon bay. After sampling, analytical processes were conducted by using a standard method and measured by ICP-OES (Inductively Coupled Plasma Optical Emission Spectroscopy). The results showed that Zn concentration was highest, 0.231 mg/kg dry weight (ppm) while in sediment and water the numbers were 1.180 and 0.790 ppm respectively. In the meantime, functional group studies through Fourier Transformed Infra Red spectroscopy revealed that OH-group (3421 cm^-1), Conjugated Double Bond (1635 cm^-1) and Ether Groups (1049 cm^-1) of callispongia sp were found. Also, the appearance of wave-number 2926 cm^-1 clearly indicates the existence of –CH sp3 group. Combining both results may guide us to establish a relation between metal concentration and organic substance transformation made during interaction inside species. Thus, trace metal investigation can be a choice in doing rapid assessment and biomonitor for the quality of coastal marine life. Furthermore, by more extensive studies, this connection could be developed and proposed as a low cost method for EIA of metal pollution in coastal zone, particularly in coral reef system.
