Abstract：Objective To establish an ICP-MS method for the determination of aluminum,cadmium,total chromium, copper,zinc and nickel in fish oil health food.Methods Samples were determinated by microwave digestion and inductively coupled plasma atomic emission spectrometry.Results The calibration curve of 6 elements were linear in the concentration range of 0~100 mg·L-1.Standard addition recovery rates were 98.8%~103.4% on average,the RSDs of precisions were in 1.6%~2.8%,the RSDs of repeatabilities were in 0.66%~4.91%.Conclusion This method was simple,rapid and accurate for the determination of fish oil health food in 6 elements,and can provide technical support for the national health food su-pervision,testing and risk monitoring.
