摘　　要：通过检测深圳沿岸海域7种贝类的重金属、麻痹性贝毒(PSP)和腹泻性贝毒(DSP)含量,了解其食用安全性.严格按照国家标准进行检测,采用SPSS 20.0对数据进行Kruskal-Wallis H检验和方差分析.结果表明:各种重金属和贝类毒素在样品中均有检出,汞污染状况良好;铜含量范围为0.52~109.65 mg/kg,超标率为13.67%;铅含量范围为0.01~3.60 mg/kg,超标率为68.35%;镉含量范围为0.015~7.807 mg/kg,超标率为53.96%.PSP和DSP检出率为100%,PSP含量范围为0.30~34.23 ug/100 g;DSP含量范围为1.88~38.41 ug/100 g.总体看来,样品铅、镉超标严重,不同种类贝类重金属含量具有差异且贝类毒素检出率较高,应引起有关部门的重视,加强该海域监测工作.Heavy metal,paralytic shellfish poison( PSP) and diarrhetic shellfish poison( DSP) in 7 species of shellfishes,which collected from Shenzhen coastal waters,were analyzed for seafood security. The samples were tested according to the national standards and the value was analysed with Kruskal-Wallis H inspection and variance analysis with SPSS 20. 0. The results showed that all heavy metals and shellfish toxins had been detected in the samples. The mercury pollution was not significant. The content of copper ranged from 0. 52 mg/kg to109. 65 mg/kg and the over-standard rate was 13. 67%. The content of plumbum ranged from 0. 01 mg/kg to3. 60 mg/kg and the over-standard rate was 68. 35%. The content of cadmium ranged from 0. 015 mg/kg to7. 807 mg/kg and the over-standard rate was 53. 96%. The detection rate of PSP and DSP was 100%. The content of PSP ranged from 0. 30 ug/100 g to 34. 23 ug/100 g. The content of DSP ranged from 1. 88 ug/100 g to38. 41 ug/100 g. Overall,the content of plumbum and cadmium severely exceeded the standard. It is statistical significant for the heavey matal concentration among different shellfish and detection rates of shellfish poison are high.Authorities should pay attention to the high detection rate of heavy metals and toxin in shellfishes and the ocean monitoring work be strengthened.
