摘　　要：[目的]了解泉州地区克氏原螯虾（Procambarus clarkii）的重金属含量及污染情况。[方法]随机收集泉州地区3个不同菜市场的克氏原螯虾180份,根据国标规定采用样品湿法消解消化法和火焰原子吸收光谱仪进行测定。[结果]镉检出范围为0-0.411 mg/kg,未超标;砷检出范围为0-0.518 mg/kg,超标率达0.9%;铅检出范围为0-0.424 mg/kg,未超标;汞检出范围为0.005-0.082 mg/kg,未超标;铬含量的检出范围0-3.178 mg/kg,超标率达2.78%;锰检出范围为0.03-32.64 mg/kg,超标率达4.6%。且不同组织器官中重金属含量不同。[结论]泉州地区的克氏原螯虾体内含量超标的重金属主要是砷、铬和锰,若长期食用这类克氏原螯虾将损害人体健康。[Objective]To analyze and assess the content of heavy metals in Procambarus clarkii Girard in Quanzhou area. [Method]The heavy metals were detected with corresponding analysis techniques recommended in national criterion in 180 samples collected from 3 markets by FAAS.[Result]The detecting ranges and the over limit rates of Cd,As,Pb,Hg,Cr and Mn were 0-0. 411 mg/kg and 0%,0-0. 518 mg/kg and0. 9%,0-0. 424 mg / kg and 0%,0. 005-0. 082 mg / kg and 0%,0-3. 178 mg / kg and 2. 78%,0. 03-32. 64 mg / kg and 4. 6%,respectively. The heavy metals distribute differently in different tissues and organs of Procambarus clarkii. [Conclusion]The mostly heavy metal pollutants beyond the national criterion were As,Cr and Mn in Procambarus clarkii of Quanzhou area,and long-term taking those Procambarus clarkii may be harmful to human health.
