摘　　要： 对广州市场常见的淡水鱼、虾和蟹等11种水产品共计63个样品进行了全氟辛烷磺酸(PFOS)和全氟辛酸(PFOA)的污染水平分析,结果显示,水产品中PFOS的检出率为100%,从组织分布来看,肝脏中PFOS平均浓度(0.25~3.18ng/g鲜重)要远远高于肌肉组织(0.05~0.41ng/g鲜重).而PFOA在水产品肌肉组织的检出率较低,仅蟹检出较高浓度的PFOA(0.05~0.47ng/g鲜重).同时,本研究对广州人群通过消费水产品而摄入PFOS和PFOA进行了初步的风险评价.结果显示,目前广州市售水产品中PFOS和PFOA的浓度不会对人体健康产生即时危害. Dietary intake is probably the main route of exposure to perfluorinated compounds(PFCs), including perfluorooctane sulfonate(PFOS) and perfluorooctanoic acid(PFOA). It is necessary to monitor the concentrations of PFCs in aquatic products which accounted for big proportion of coastal populations diet. PFOS and PFOA concentrations were measured in muscle and liver tissues of 63 fishery samples collected from Guangzhou province in China, an ultraperformance liquid chromatography and tandem mass spectrometry(LC/MS/MS) was used. The mean concentrations of PFOS in muscle and liver were 0.05~0.41ng/g and 0.25~3.18ng/g based on wet weight separately, while lower concentrations of PFOA were detected in aquatic products. Average daily intake and hazard ratio values for Guangzhou residents to PFOS and PFOA exposure via aquatic product consumption showed that concentrations of PFOS and PFOA in aquatic products from Guangzhou market had no health risk.
