| 根据2005年4月和10月厦门市贝类生产环境区划调查资料，着重对僧帽牡蛎(Saccostrea cucullata)、菲律宾蛤仔(Ruditapesphilippin adams)、泥蚶(Tegillarca granosa)和缢蛏(Sinonovacula constricta)的软体部、胃含物、外套膜、卵、肌肉和外套腔液中的重金属含量进行探讨和研究。结果表明,厦门4种养殖贝类体内Cu，Pb，Cd和Zn的湿质量比分别为0.88～60.3 mg/kg，0.12～0.48 mg/kg、0.04～0.72 mg/kg 和12.4～163.5 mg/kg ，平均湿质量比分别为16.3，0.24，0.38，63.9 mg/kg。在不同养殖水域，同种贝类体内重金属的含量差异较大，在相同养殖水域贝类体内重金属的平均含量种间差异也较大。4种贝类的胃含物中重金属的平均含量最高，外套膜和软体部次之，外套腔液含量最低。根据《无公害食品水产品中有毒有害物质限量》的标准，对4种贝类体重金属的污染程度进行评价，结果表明，僧帽牡蛎、菲律宾蛤仔和缢蛏体中重金属的含量均未超标，但泥蚶体内Cd的含量略微超标。 |

| Abstract: |
| According to survey data of shellfish culture areas of Xiamen in April and October 2005, the contents and distributions of heavy metals in different tissues (soft body, stomach content, mantle, spawn, muscle and mantle cavity fluid) of Saccostrea cucullata, Ruditapesphilippin adams, Tegillarca granosa and Sinonovacula constricta were analyzed and discussed. The result showed that the ranges of wet weight contents of Cu, Pb,Cd and Zn in these four shellfishes respectively were (0.88～60.3) mg/kg, (0.12～0.48) mg/kg，(0.04～0.72) mg/kg and (12.4～163.5) mg/kg, with 16.3, 0.24，0.38 and 63.9 mg/kg as the mean value. The heavy metals contents of the same kind of shellfish were remarkably varied in different culture areas. But the average contents of heavy metals with interspecies were obviously varied in the same culture waters. The contents of heavy metals in stomach were higher than those in mantle and soft body, and those in mantle cavity fluid were least. In addition, according to the standards of Not public disaster foods, Tolerance Limit of Deleterious Maters in Aquatic Products, the pollution level of four shellfishes was assessed as follows: the concentrations of Cu, Pb, Cd, Zn in Ruditapes philippinarum, Sinonovacula constricta and Ostrea cucullata were all below the standard values, except the contents of Cd in Tegillarca granosa. |
