- Fish produce is one kind of food which is commonly to be liked by most of people because so easy to find and easy to use. Fish produce which avaiable in market is packaged in cans and are produced in kinds of brand. The aims of this research is to know how much content of plumbum and kadmium in canned fish. Quantitative analysis of plumbum and kadmium was conducted by using Atomic Absorption Spectrophotometry and was performed at the wavelength of 283,3 nm for plumbum and 228 nm for kadmium. The advantages of this method, that we can make sure how much one kind of metal content without disturbing by other metal. Other side, is easy n simple to do, less interfrensi and good choise for little amount of metal analysis because have high response ( limit detection less of 1 ppm). The results showed that the average of plumbum content in SB, SF, and SV was 0.1042 ± 0.0104 μg/g; 0.1783 ± 0.0122 μg/g dan 0.2605 ± 0.0304 μg/g with limit of detection was 0,0182 μg/ml and limit of quantitative was 0.0606 μg/ml. Method validation test exhibited accuracy with percent recovery was 95.27% and RSD 6.45%. However the results showed that the average of kadmium content in SB, SF, and SV was 0.0506 ± 0.0004 μg/g; 0.1437 ± 0.0031 μg/g dan 0.1004 ± 0.0014 μg/g with limit of detection was 0.0139 μg/ml and limit of quantitative was 0.0464μg/ml. Method validation test exhibited accuracy with percent recovery was 91.90% and RSD 3.69%. The results of research showed that canned fish already contaminated with plumbum and cadmium, but sample did not passed the maximum limit that allowed by Badan Standarisasi Nasional (1995) in SNI 01-3708-1995 that is 0.3 mg/kg for plumbum and 0.1mg/kg for cadmium.
