Heavy metals,polycyclic aromatic hydrocarbons (PAHs),and perfluorinated alkyl substances (PFASs) polluted in 155 samples of two marine crustaceans (Oratosquilla oratoria and Portunus trituberculatus) harvested in the Zhoushan fishing ground in the East China Sea were assessed.The results showed that Pb,Hg,and iAs in the whole edible parts of O.oratoria and P.tritubercu-latus were at trace levels,far below the limits set by the China\'s national standard,whereas the exceeding standard rates of Cd in the whole edible parts of O.oratoria and P trituberculatus were 98.6％ and 75.6％,respectively.Moreover,the average Cd levels and the exceeding standard rates of Cd in the visceral tissues of O.oratoria were significantly higher than those in the muscle tissues (4.64 mg kg-1 vs.0.49mg kg-1 and 96.7％ vs 30％,respectively).PAHs with high detection frequency in the two marine crustaceans in-cluded NA,AC,FL,and PHE.Total contents of 15 PAHs (abbreviated as Σ 15PAHs) in whole edible parts of O.oratoria and P.trituberculatus were 10.75-65.9 μg kg-1 (mean=18.7μg kg-1) and 13.26-181 μg kg-1 (mean=24.2μg kg-1),and those in the muscle and the visceral tissues of P.trituberculatus were 9.58-160μg kg-1 (mean=21.1 μg kg-1) and 18.22-201 μg kg-1 (mean=32.7μg kg-1),respectively.Furthermore,PFASs that were found at high contents included PFOA,PFOS,and PFOSA,and total contents of 23 PFASs (Σ23 PFASs) ranged 0.0162-5.104 μg kg-1 (mean =0.915 μg kg-1).Collectively,the present work provides new data on the contamination in two marine crustaceans captured in the Zhoushan fishing ground in the China East Sea,which can be useful for making suggestions on proper consumption amounts of the two marine crustaceans.
