A method was developed to simultaneously determine 13 elementals by microwave digestion -ICP/MS in aquatic products with Cesium and Indium as internal standards .HNO3 -H2 O2 was used to digest the samples.The method detection limits of the 13 elementals ranged from 0.05 ng/g to 0.064 μg/g and the RSDs of 4 parallel determination were less than 5%. The spiked recoveries of silver carp were between 81%and 117%.%用硝酸-双氧水体系微波消解，以In、Sc为内标，采用电感耦合等离子体质谱法（ ICP/MS）同时测定水产品中V、Cr、Co、Ni、Cu、Zn、As、Se、Cd、Sb、Ba、Tl、Pb等13种元素。各元素的检出限在0．05 ng/g～0．064μg/g之间，样品平行测定4次的RSD＜5％，鲢鱼样品的加标回收率在81％～117％之间。
