PENGGUNAAN BAHAN ACUAN BERSERTIFIKAT OYSTER TISSUE 1566b SEBAGAI INTERNAL QUALITY CONTROL UNTUK MENENTUKAN KADAR TIMBAL TOTAL DALAM TEPUNG IKAN MARLIN DENGAN ELECTROTHERMAL ATOMIC ABSORPTION SPECTROMETRY
Abstract: Lead is widely knows
as one of the harmful pollutants for humans. Contaminated fishery built by lead
may endanger the consumption body. Therefore, contamination monitoring for the
fishery products is necessary to be conducted. To ensure the validity of data,
Oyster Tissue 1566b certified reference material was used as Internal Quality
Control. Marlin fish powder and certified reference materials were analyzed
with the same method, personnel, duration or time, equipment and environmental
conditions. As the results, it was found that the lead contained in CRM was
0.306 mg.kg-1 with 11.9 % rsd, which is within range of lead content in the certificate. The method was applied for
Marlin Fish. Lead content obtained in this study (1.821 mg.kg-1 with 11.06 %
rsd) can be reported with high level of confidence.
