Abstract： Fifty-one trace-elements in water (underground water♦ groundwater> drinking water and etc.) were determined simultaneously by ICP-MS Analytical conditions* including the choice of isotopes for determination* working parameters of the instrument and test for precision and limits of detection etc. , were studied. Valuer of the 51 elements determined by this method checked quite well with the standard valuer» giving relative deviations less than ±10% (besides tungsten). Results of recovery tests were in the range of 90% —110%・

水中元索的监测多用分光光度法、原子荧光光 谱法、原子吸收光谱法、电感耦合等离子体发射光谱 法等，这些方法有些前处理复杂，有些是一次只能分 析单个元素
