摘　　要：目的调查河北省市售贝类中脂溶性贝类毒素的污染状况。方法在2018年8月—2020年4月间,对河北省市售7大类贝类样品进行采集,共354份,采用超高效液相色谱-串联质谱法(ultra performance liquid chromatography-tandem mass spectrometry,UPLC-MS/MS)进行脂溶性贝类毒素的检测。结果 354份样品中,阳性样品17份,检出率为4.8%,检出含量较低,检出品种有毛蚶、贻贝、扇贝、牡蛎,毒素组分有虾夷扇贝毒素(yessotoxin,YTX)、同源虾夷扇贝毒素(homo-YTX)、大田软海绵酸(okadaicacid,OA)、鳍藻毒素(dinophysistoxins, DTXs)(DTX1、DTX2)、蛤毒素2(pectenotoxin-2, PTX2)。结论河北省市售贝类中脂溶性贝类毒素暴露风险很低。Objective To investigate the pollution status of lipophilic shellfish poison in commercial shellfish of Hebei province.Methods From August 2018 to April 2020,354 samples of 7 species of shellfish in seafood sold of Hebei province were collected.The detection of lipophilic shellfish poison was detected by ultra performance liquid chromatography-tandem mass spectrometry.Results Among 354 samples,17 samples were positive.The detection rate was 4.8%,and the detection content was low.The detected species were scapharca subcrenata,mussel,scallop,oyster,and toxin components were yessotoxin(YTX),homo-YTX,okadaic acid(OA),dinophysistoxins(DTX1,DTX2),pectenotoxin-2(PTX2).Conclusion There is a low exposure risk of lipophilic shellfish poison in commercial bivalves of Hebei province.
