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.
