ABSTRACT: Spermonde Archipelago has been found to have a high
sponge biodiversity. Sponges that have feeding behavior as filter feeder can be
exposed to heavy metals, including Zn metal. Zn is an essential metal that is
physiologically needed by sponge to catalyze chemical reactions and generally
operates on enzymes. A study on Zn pollution level in Spermonde Archipelago
from zone I to Zone IV was conducted by analyzing Zn concentration in
sponges, sediments, and seawater. Physicochemical parameters measurement in
Spermonde Archipelago indicates that Spermonde Archipelago meets the
requirements for sponge growth. Callyspongia aerizusa can be used as
metal pollution indicator because this sponge can accumulate heavy metal Zn
in high level (99.30 mg/kg dry weight). This sponge was derived from
Kondingareng Lompo island at zone III. In addition, Kodingareng Lompo island
waters had the highest Zn concentration compared to other islands. Sediments
from Lae-Lae island at zone I had the highest Zn metal concentration. Lae-Lae
island is the nearest island to Makassar coastal line.
