Abstract

This study determined the distribution levels of heavy metals Pb, Cu, and Ag in sediments in the waters of Saparua Island. It characterized the sediments in the seas of Saparua Island. Parameters are physical and chemical parameters of waters, determination of total organic carbon (TOC), and digestion of sediment samples for SSA testing. The results obtained levels of copper metal contained in the sediments from 0.1583–1.9531 mg/L and <4–78 ppm. The level of lead metal contained in the sediments in the waters of Saparua Island ranges from <12–26 ppm. Metal oxides, especially metal oxides formed from Cu, were found in sediments in the waters of Saparua Island with location points P.8 and P.9, namely CuO 0.0056% and 0.0031% and in sediments in Saparua Island waters with a value of 2Ɵ in sediment samples. P.2, P.3, P.6, P.8, P.9, and P.11 have the highest intensity which is the characterization of metal oxide 2Ɵ= 27.7464°, 29.4759, 26.2979, 26.6686, 26.7007, and 24.3695 indicate the presence of CaO (calcium oxide) phases at points P.2, P.3, and P.6. the SiO2 (silica) phase which is the most abundant metal in sediment samples P.8, P.9, and P.11 based on the XRF test.

Abstract

Mercury is a neurotoxic heavy metal with high bioaccumulation ability in aquatic biota, such as mangrove crabs (Scylla serrata), mangrove snails (Telescopium telescopium), and mangrove mussels (Polymesoda erosa), which are widely consumed by humans, and used as bioindicators of pollution. This study aimed to analyze the effect of mercury solution concentration and species differences on mercury absorption in the three biota. The method used was experimental treatment with mercury concentrations of 1 ppm, 5 ppm, 10 ppm, and control. Samples were analyzed using the AAS Cold Vapor method at the IPB Bogor Proling Laboratory. Data were analyzed descriptively and inferentially using two-way Anova with an α level of 0.05, followed by the Duncan Test if the hypothesis was accepted. Research data will be processed using SPSS 26.0 software. The results showed that mercury concentration and species differences influenced the ability to absorb mercury. Mangrove clams had the highest mercury accumulation compared to mangrove snails and mangrove crabs, especially in the 5 ppm and 10 ppm treatments. The highest mercury exposure occurred on the second day of observation.
