A rapid, sensitive, precise and accurate method for the determination of lead (Pb) in bivalve molluscs by graphite furnace atomic absorption spectrometrywas developed in regard to AOAC Official Method 999.10 and ISO/IEC 17025. This approach was investigated so as to minimize the analysis time, taking into consideration the sensitivity. For method validation, precision and accuracy by addition recovery tests have beenevaluated as performance criteria.
