Title: Contamination characteristics of perfluorooctane sulfonate(PFOS) and perfluorooctanoic acid(PFOA) in aquatic products from Guangzhou

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.Read More
