Abstract

Lead, cadmium, and mercury concentrations have been measured in Leiognathus equulus collected from Tuban, Lamongan, Sidoarjo, Pasuruan and Banyuwangi coast of East Java during January to April 2010. Determination of lead, cadmium, and mercury have been conducted using Absorption Atomic Spectrophotometer. The metal contents were expressed in mg.Kg-1 dry weight. Except the mercury concentration, the results showed that there were contamination of lead, and cadmium in Leiognathus equulus. In all samples, mercury concentration below the limit of detection. The highest cadmium level was found in fish from Lamongan (0,043 mg.Kg-1) and the highest lead level was found in Tuban samples (0,042 mg.Kg-1). The results showed that there were negative relationship between metal accumulation and fish weight. The concentration of Pb, Cd, and Hg from Tuban, Lamongan, Siodarjo, Pasuruan, and Banyuwangi were below acceptable limits for human consumption.
