Pretreatment method for the determination of total arsenic in seafood sample was studied. NIST SRM 1566a oyster tissue (<TEX>$14.0{\pm}1.2mg\;As/kg$</TEX>) as a standard arsenic compound in order to establish the decomposition method. We confirmed that the best way for pretreatment of seafoods to analyze total arsenic content precisely was <TEX>$HNO_3-H_2SO_4-HCIO_4$</TEX> method by comparison of two methods which are dry ashing and wet ashing methods.
