运用小白鼠生物检测法,对产自我国黄海海域贝类进行腹泻性贝类毒素检测。本研究于2007年11月至2008年10月在深圳罗湖水产批发市场定期采集市售贝类,包括虾夷扇贝、栉江珧和胖江珧,61份样品。结果显示,黄海海域贝类腹泻性贝类毒素检出率为44.26%,超标率为24.59%;所有种类的贝类均受到不同程度腹泻性贝类毒素污染,其中虾夷扇贝腹泻性贝类毒素污染最为严重;贝类样品的阳性检出率和超标率随季节变化而存在一定差异,春季样品腹泻性贝类毒素含量最高。
The diarrhetic shellfish poisoning(DSP) in shellfish cultured in the Yellow Sea,China was investigated by the mouse bioassay.61 samples including Patinopecten yessoensis,Atrina pectinata and Pinna inflate were collected from Luohu seafood wholesale market in Shenzhen during November 2007 to October 2008.The results show that the positive rate and the over standard rate of samples contaminated by DSP were 44.26% and 24.59%,respectively.All shellfish species were contaminated by DSP,and scallop Patinopecten yessoensis was the most seriously polluted species.The distribution of the positive rate and the over standard rate were of seasonal difference,the samples collected in spring had the highest level of DSP.
