ABSTRACT
To investigate the contamination characteristics of PFASs in aquatic products, 254 samples belonging to 6 species, including fishes, crustaceans, cephalopods, etc., were collected from Guangzhou, and 23 PFASs were determined by UPLC-MS/MS. The total detection rates of the various sample species ranged from 93.5% to 100%, and the concentrations of PFASs were relatively higher in the fishes and crustaceans. 13 PFAS components were detected in the fish samples, but only 6 PFAS components were detected in haliotis samples, and obvious differences were observed among the different species sampled. PFOA and PFOS were the predominant pollutants, with detection rates of 75.6% and 76.8%. The concentrations of PFOS were in the range of 0.19-192.27 µg·kg-1, which were obviously higher than those of the other PFAS components, and their total contamination contribution factor reached the highest percentage of 35.15%. PFOS was a major contributing factor to the PFAS contamination of fishes, crustaceans, siphonopods, and processed products; however, the predominant pollutant in Haliotis samples was PFBA. The results of the risk assessment indicated that the concentrations of PFOA and PFOS would not give rise to timely harm to the consumers.
