KADAR LOGAM Cu, Pb, Cd DAN Cr DALAM IKAN SEGAR DAN KERANG DARI TELUK JAKARTA TAHUN 1995/1996

A study on trace metal concentration in freshfish and shellfish from Jakarta bay was conducted in order to know trace metal contamination in freshfish and shellfish consumed by Jakarta community. This study was carried out for JO months. Samples were taken from fish market and fishpond at Muara Angke once in a month. These metals were determined by Atomic Absorption Spectrophotometer using nitrogen-acetylen flame for Cr and the others (Cu, Pb and Cd) using air-acetylen flames. The results showed that average concentration of these metals in freshfish and shellfish were not exceeding the permissible concentration except Cd in shellfish. The average concentration of Cd in shellfish was 0,45 ± 0,05 ppm, higher than the permissible concentration and the concentration of these metals in dry season were higher than rainy season.
