In order to explore the more scientific,more simple method for the determination of Hg in aquatic products,the aquatic product was digested and treated with wet digestion for Hg determination by AFS,using H2NO3-H2O2-HClO4as digestion system.The measurement conditions were optimized and the regression equation was：IF=1 256.444 9C-3.860 5,the related coefficient was：r=0.999 27;Detection limit was 0.001 8 μg·kg-1;Linear range was 0～0.20 ng·mL-1 Recovery was 91.4%～102.2%;Relative standard deviation was 0.4%～4.8%.The sample could be digested completely with few dosage of reagent,be easy operated,had low detect limit and the results were correct and reliable by using this method.
