摘要：

The pollution caused by metals is one of the main problems in water of our country and as well as in other countries of the world. Shellfish is the most prominent choice for monitoring metals in the river. The content of heavy metals in shellfish is related to the content of metals in the water. In this study, the shell samples were digested with hydrogen peroxide nitric acid digestion system, and the collision cell was used to eliminate multi atom ion interference. The content of Al, V, Cr, Fe, Mn, Co, Ni, Cu, Zn, As, Se, Sr, Mo, Cd, Ba and Pb in Unio douglasiae shells were determined. The correlation coefficient of standard curve was between 0.9993-1.0000, and the detection limit of each element was between 0.140 to 23.61 gkg(-1), the recovery range was from 79.0% to 107.9%, and RSD% was between 0.70%similar to 9.09%. From the accuracy and precision of the test, the detection method is accurate and efficient, and can meet the requirements of the metals detection in shell samples.
