Lead Analysis in Green Shellfish, Feather Shellfish, and Sediment in Jakarta Bay

Abstract

Lead is a heavy metal that produced from industrial waste and found in the waters. Lead in trace amounts is not harmful to humans, but if the amount exceeds the limit it may lead to acute and chronic poisoning. The purpose of this study was to determine the content of Lead in green shellfish, feather shellfish, and sediment. The method used is Atomic Absorption Spectrophotometry (AAS), which includes validation includes linearity determination, the limit of detection and limits of quantitation, accuracy and precision, and analysis of lead in the sample. The results showed that linierity 0.9971, the limit of detection 0.04 µg/g, the limit of quantitation 0.14 µg/g, accuracy of shellfish and sediment samples respectively are 99.66% and 87.64%, coefficient of variation of shellfish and sediment samples respectively are 0.64% and 1.07%. Result of analysis of lead in green shellfish is 13.98±1.92 µg/g, feather shellfish is 33.64±4.66 µg/g, and the sediment is 28.67±1.06 µg/g. Results of the analysis of the samples show that lead levels content is above the premissible limit of 1.5 µg/g set by Badan Pengawasan Obat dan Makanan No.HK.00.06.1.52.4011.
