Analisis Konsentrasi Merkuri (Hg) Pada Sampel Sedimen Di Perairan Pulau Panjang Banten

Panjang Island is located in Banten Bay, Banten Province, is a small island which is close to urban and industrial areas, including the food industry, oil and gas industry, ship industry and iron making industry. Most of Panjang Island’s people are fisherman. Antrophogenic activities impact on the conditition of the waters in Panjang Island, i.e. heavy metal pollution such as Mercury (Hg) which threathen marine life around the Panjang Island area. Mercury (Hg) is a pollutant that is harmful to marine environment. This study aims to determine the concentration of Hg contained in samples of coastal sediments from Panjang Island and its distribution. Surface sediment collection from the waters of Panjang Island will be carried out in February 2023. Four stations and eight sampling point in each station were determined using a purposive sampling method. Heavy metal Hg content in coastal sediment was analyzed using the Cold Vapor Atomic Absorption Spectrometry (CVAAS) method. Wind data for February 2023 was obtained from the Meteorology, Climatology and Geophysics Agency (BMKG) at Serang Maritime Station for the region surrounding Panjang Islands. The results show that the average Hg concentration in sediments of the Panjang Island Waters is 285. 89 µg/kg, according to the quality of ANZECC & ARMCANZ (2000) this value is included in the lower category. The source of Hg in the sediments is supposed originated from human activities surrounding Panjang Island and its distribution is influenced by wind and coastal currents which cause decreasing Hg concentrations from offshore.
