广东沿海贝类4种重金属含量分析和评价

Analysis and assessment of the content of four heavy metals in shellfish along Guangdong coastal waters

    摘要
  • 摘要: 根据2007年6~9月对广东沿海4种贝类养殖区90个样品的检测结果，研究了贝类体内重金属的含量和累积，对贝类的质量安全进行评价。结果表明：（1）菲律宾蛤仔Ruditapes philippinarum体内含量大小顺序为铜（Cu）镉（Cd）铬（Cr）铅（Pb），太平洋牡蛎Crassostrea gigas和近江牡蛎C. rivularis的大小顺序都是CuCdPbCr，而翡翠贻贝Perna viridis的大小顺序则是CuPbCdCr；（2）菲律宾蛤仔、太平洋牡蛎、翡翠贻贝未受重金属污染，但部分近江牡蛎体中Cd和Cu含量已超过中国农业行业标准无公害食品：水产品有毒有害物质限量标准，应该引起重视。

     

    Abstract: Based on the detected data of the content of Cd, Cu, Pb and Cr in 90 samples of four shellfish species in Guangdong coast from June 2007 to September 2007, the accumulation and distribution of heavy metal in shellfish were studied, and the safety and healthy quality of shellfish were evaluated. The results were obtained as follows: (1) The average content of heavy metal contents in Ruditapes philippinarum is CuCdCrPb, in Crassostrea gigas and C. rivularis is CuCdPbCr, in Perna viridis is CuPbCdCr; (2) R. philippinarum, G. gigas and P. viridis have not been polluted by heavy metals, but the contents of Cd and Cu in some C. rivularis highly exceeded the limit standard of non-environmental pollution food, the limit for the deleterious matters in the aquatic product. We should pay attention to this issue.
