Konsentrasi Logam Berat Kadmium Pada Air, Sedimen dan Deadema setosum (Echinodermata, Echinoidea) di Perairan Pulau Ambon

Terbitan Jurnal Ilmu Kelautan Undip. Edisi Juli 2011 Abstract. Biomonitoring is a good approach to estimate the status of pollution in the marine enviroments. In this research, the analysis of heavy metal concentrations of cadmium (Cd) in water, sediment and body compartments Deadema setosum aquatic derived from the island of Ambon were performed. Samples were obtained and then analyzed the concentration of Cd using atomic absorption spectrophotmeter (AAS). Results of analysis of Cd concentration in water are 0:01 to 0:03 ppm and the sediment are 0:17 to 0:32 ppm, whereas the body parts of Deadema setosum are spines, shells, gonads, and intestines in a row 0:30 to 1:19, 0.31-0.85, 1:30 to 1:39, and 1.31-1.95 ppm. The results of analysis of heavy metals Cd relationship in the water with heavy metals Cd levels in the body of D. setosum showed that the relationship is not significant. But the significant relationship is shown in the results of analysis of the relationship between heavy metal Cd in sediments with heavy metals Cd levels in the body of D. setosum. The results of this study indicate that the waters of the island of Ambon has been polluted by heavy metals Cd and D. setosum can be used as a biomonitoring of heavy metal pollution at the sea.
