Essential Metal Co In Sponges (Porifera) From Spermonde Archipelago

[Full Text]



Lydia Melawat, Kristiana Pasau



Keywords: filter feeder, heavy metal, ICP-OES.



ABSTRACT: Sponge is an invertebrate animal commonly found in Spermonde Archipelago. It is known as an animal living as filter feeder. Sponge is capable of accumulating heavy metals including cobalt (Co). Co is an essential metal in low concentration but a pollutant in high concentration. Sponges used in this study were Melophlus sarassinorum, Callyspongia aerizusa, and Clathria reinwardtii. Sponges were analyzed based on modified Muller et al (1998) method. Co concentrations were determined using ICP-OES. Co metal in three sponge species from seven different islands indicated equal concentration (2 mg/kg) except for the sponge Callyspongia aerizusa from Lae-Lae and Barrang Caddi islands that accumulated lower Co (0.5 mg/kg).
