THE POTENTIAL OF Clathria reinwardtii as BIOACCUMULATOR OF HEAVY METAL Cu

Heavy metal Cu is an essential metal required by living organisms but a pollutant in water environment when existed in a level above the treshold level. The capability of sponge Clathria reinwardtii in accumulating heavy metals was analyzed according to modified Müller et al. (1998) method, and the sediment was analyzed according to Loring and Rantala in Rochyatun et al., (2006). Cu concentrations were measured by ICP-OES. The results indicate that Clathria reinwardtii was capable of accumulating the highest Cu level compared to other sponges. The highest Cu level analyzed in Clathria reinwardtii was 161.3 mg/kg

DISTRIBUSI LOGAM ESSENSIAL Cu DALAM SPONGE (PORIFERA) DI KEPULAUAN SPERMONDE

A research on essential metal distribution of copper in Spermonde waters has been carried out. Sponge species of Melophlus sarassinorum, Callyspongia aerizusa, dan Clathria reinwardtii were identified and analyzed accordingly. Copper level were measured using Inductrively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) and the results showed that highest concentration was found in Clathria reinwartii  48.3 ppm. Copper distribution in sponge skeleton is higher than in its tissue and seemingly in terms of species the highest concentration is Clathria reinwartii taken from Barrang Lompo waters. In the meantime, Samalona waters contain highest concentration in its sedimen (3.96 ppm). Apparently Spermonde waters is beginning being interferred by metal pollution
