Microwave digestion for the determination of arsenic, cadmium and lead in seafood products by inductively coupled plasma atomic emission and mass spectrometry

摘要: A single microwave digestion procedure was developed for use with a variety of seafood products. Inductively coupled plasma atomic emission and mass spectrometry were used to determine the levels As, Cd Pb in samples tuna, salmon, shrimp, walleye, clams, oysters lobster. The precision ten replicate analyses clams 2.1% As at 10.0 µg g–1 level, 5.6% 0.067 level 2.5% 0.079 level. Acceptable spike recoveries each sample types achieved using both detection methods. Results two standard reference materials good agreement certified values
