摘　　要：目的了解德阳市市售小龙虾中各金属元素含量水平及分布规律,初步判断德阳市居民受到有害金属元素危害的可能性。方法采用分层随机抽样,在德阳市采集共计102例样本,通过微波消解仪消解样品后,使用电感耦合等离子体发射光谱仪(ICP-OES)和电感耦合等离子体质谱仪(ICP-MS)对17种矿物质元素和7种有害金属元素进行检测。结果矿物质元素在小龙虾各部位均有检出,含量各不相同,以矿物质总量来看,虾头>虾线>虾鳃>虾尾>虾黄。对有害金属而言,虾尾中不存在超标情况,虾黄中As、Cu、Cd的超标率分别为97.0%、2.97%、27.7%,Hg、Pb、Cr未超标;As、Cu、Cd、Pb、Cr、Al在非可食部位均有超标情况,超标率为2.17%~100%。所有金属元素在德阳和湖北两地小龙虾中的富集规律一致,但含量各不相同。在不同采样环节中,虾尾中的有害金属元素均不超标;As、Cu、Cd在虾黄的超标率为2.8%~97%,其余元素不超标。在不同生长环节中,除As外,青壳虾和红壳虾对有害金属元素的蓄积差异不显著。结论小龙虾矿物质含量丰富,营养价值高,德阳市本地居民日常摄入小龙虾受到的有害金属元素危害风险较低。Objective To understand the various metal elements content and distribution in crayfish sold in Deyang,and to initial determine the harm of hazardous metallic elements to residents in Deyang.Methods A total of 102 samples were collected in Deyang using a stratified random sampling approach,the samples was digested by microwave digestion,17 mineral elements and 7 harmful metal elements were detected using inductively coupled plasma optical emission spectroscopy(ICP OES)and inductively coupled plasma mass spectrometry(ICP-MS).Results Mineral elements in all parts of the crayfish were detected and the content varies,in terms of total minerals,crayfish brain>crayfish intestine>crayfish gills>crayfish meat>crayfish hepatopancreas.For harmful metals,there was no exceedance in crayfish meat,As,Cu,Cd in crayfish hepatopancreas exceeded the standard rate of 97.0%,2.97%,27.7%,Hg,Pb,Cr did not exceed the standard,As,Cu,Pb,Cr and Al were all exceeded the standard in the non-edible parts by 2.17%to 100%.The enrichment pattern of all metal elements in crayfish in Deyang and Hubei was consistent,but the contents varied.In different sampling sessions,none of the harmful metal elements in crayfish meat exceeded the standard;As,Cu,Cd in crayfish hepatopancreas exceeded the standard rate of 2.8%-97%,and the rest of the elements did not exceed the standard.In different growth stages,except for As,there was no significant difference in the accumulation of hazardous metal elements between green and red crayfish.Conclusion Crayfish have a high mineral content and abundant nutrients,and local residents in Deyang City have a lower risk of heavy metal hazards in their daily intake of crayfish.
