运用微波消解技术与电感耦合等离子发射光谱（ICP-AES）技术，建立沙虫中重金属元素的测定方法。测定了沙虫中铜、铅等8种重金属元素的含量，各元素的系列标准液，浓度与发光强度呈良好线性关系，相关系数均在0.999以上，加标回收率为98%～114%。结果表明，沙虫中铜、铅、镉、铬、锰、砷、汞、钡8种重金属的含量分别是：17.119、3.781、0.695、7.351、1997.982、0.620、0.144、4.249 mg/kg。与国家规定的水产品中重金属限量标准相比，除了汞、铜未超标外，沙虫中锰超标100倍、镉超标近7倍、铅超标近4倍、铬超标3.5倍、砷超标1倍多。沙虫污染较为严重，呼吁相关部门予以关注，还东方市及周边海域一方净土。采用微波消解技术和 ICP-AES 相结合径向观测测定重金属元素含量，与常规分析方法相比，有省时、省力、环境污染小、基体效应小、稳定性好、灵敏度高、分析速度快、准确及实现多元素同时分析等优点，应用于沙虫中多元素的测定，结果令人满意。

In order to develop a method for measuring of elements in Sipunculus nudus, the contents of Cu, Pb, Cd, Cr, Mn, As, Hg and Ba were determined by actively coupled plasma atomic emission spectrometry (MWD) and microwave diges-tion (ICP-AES). The results showed that correlation coefficients al kept higher than 0.999 and the recovery rates of sample added standard solutions were in 98%-114%. The results indicated that the contents of Cu, Pb, Cd, Cr, Mn, As, Hg and Ba were 17.119, 3.781, 0.695, 7.351, 1997.982, 0.620, 0.144, 4.249 mg/kg respec-tively. The contents of Mn exceeded national limit by hundredfold, Cd sevenfold, Pd fourfold, Cd three-and-a-half-fold, and As onefold. Sipunculs nudus became seriously pol uted. Therefore, it is necessary to formulate robust policies to fol ow closely and pay close attention to coastal areas pol ution around Dongfang City.
