农产品产地土壤样品经四酸（盐酸、硝酸、氢氟酸和高氯酸）分解和王水提取后，采用电感耦合等离子体质谱（ICP-MS）法对重金属元素铬、镉和铅进行分析，通过在线加入内标校正基体效应和接口效应，应用干扰校正公式消除元素质量数干扰。测定元素校正曲线相关系数在0.9995以上，元素方法检出限（3s）在0.013~2.33μg.g-1之间，RSD%＜10（n=12），加标回收率在98.1%~103.4%之间，结果令人满意。
農產品產地土壤樣品經四痠（鹽痠、硝痠、氫氟痠和高氯痠）分解和王水提取後，採用電感耦閤等離子體質譜（ICP-MS）法對重金屬元素鉻、鎘和鉛進行分析，通過在線加入內標校正基體效應和接口效應，應用榦擾校正公式消除元素質量數榦擾。測定元素校正麯線相關繫數在0.9995以上，元素方法檢齣限（3s）在0.013~2.33μg.g-1之間，RSD%＜10（n=12），加標迴收率在98.1%~103.4%之間，結果令人滿意。

The agricultural soil samples were decomposed with four acids (hydrochloric acid, nitric acid, hydrofluoric acid and perchloric acid) and extracted with aqua regia. The heavy metal elements, such as Cr, Cd and Pb were analyzed with ICP-MS method. The matrix effect and interface effect were corrected by the on-line addition of internal standards, and the element mass number interference was eliminated by the correction formula of interference. All the tested elements’ correlation coefficients were over 0.9995, the detection limits (3s) of these elements were found in the range from 0.013 to 2.33μg.g-1, RSD%<10(n=12), and the adding standard recovery was between 98.1%and 103.4%. The results were satisfied.
