    摘要：目的 调查研究入境可再生废物携带重金属状况。方法按集装箱采样，采用超声波水洗的方法对可再生废物进行前处理，对水样进行微波消解，用原子吸收光谱法对包括镉、铬、铅、镍、锌等重金属元素进行检测。结果 检测116份样本，其中镉检出率为44.83％；铬检出率0％；铅检出率34.48％；镍检出率75.86％；锌检出率为100％。结论对于进口可再生废物重金属污染程度的限制，并没有国家或行业标准的依据可查，入境可再生废物对从业人员的身体健康和环境危害的评价，有待深入研究。

    Abstract:   Objective  To  investigate heavy metal stantus carried by immigrationrecyclable waste.  Methods   The pretreatment ofsamples were washed by ultrasonic, and the water samples weretreated by microwae-assisted digestion. Heavy metal Cd, Zn, Cr, Ni,Pb were detected by Atomic Absorption Spectrometer inlab.   Results    In 116 immigrationrecyclable waste samples, the detection rate of Cd, Cr, Pb, Ni, Znwas 44.83%,0%,34.48%,75.86%,100%,respectively.   Conclusion   There exists no industry standards ornational standards to limit the degree of heavy metal inimmigration recyclable waste. Evaluation of immigration recyclablewaste against health of practitioners and environmental hazardsneeds futher study.
