KADAR LOGAM BERAT TIMBAL (Pb) DAN TEMBAGA (Cu) DALAM CUMI-CUMI DAN KEPITING (Studi Kasus Pada Cumi-Cumi dan Kepiting yang didaratkan di Tempat Pendaratan Ikan Muncar, Banyuwangi, selama tiga bulan, Desember 2004-Februari 2005)

Abstract

Determination of lead (Pb) and copper (Cu) in squid and crabs have been done (Case Study of Squid and Crabs from Muncar Fish Landing Station, Banyuwangi, on December 2004-February 2005). The purpose of this research are learns the quantity of lead (Pb) and copper (Cu) heavymetal in squid and crabs, and the fluctuation along three months (December 2004-February 2005). The squid and crabs obtained by common random intake technique. The squid and crabs dissolve by wet destruction. Pb and Cu content of squid and crabs determination by Atomic Absorption Spectroscopy (AAS). Based on the result of the research obtained the fact of lead (Pb) and copper (Cu) heavymetal in squid and crabs. The mean amount of lead (Pb) heavymetal in squid is 8.7724 ppm, the highest is 10.4579 ppm and the lowest is 7.4705 ppm. The mean amount of lead (Pb) heavymetal in crabs is 23.6651 ppm, the highest is 30.1089 ppm and the lowest is 17.2383 ppm. The mean amount of copper (Cu) heavymetal in squid is 28.4157 ppm, the highest is 63.3964 ppm and the lowest is 10.1023 ppm. The mean amount of copper (Cu) heavymetal in crabs is 27.6343 ppm, the highest is 32.3206 ppm and the lowest is 17.0473 ppm. The amount pattern of lead (Pb) and copper (Cu) heavymetal in squid and crabs fluctuated as long as the sample intake periods (December 2004-February 2005).
