  1. Note. Sampling Sites: A, Caijiabao; B, Beitangkou; C, Gaoshaling; D, Nanpaihe; E, Yugangkou. PFC is the percentage of positive fluorescence cells of the total cells. 5-AZA-CdR DTE: 5-AZA-CdR toxicity equivalent for demethylation potential (μM). All of the elements are the ICP-MS results for wet weight (mg/Kg). FSV is the standard value of the maximum levels for certain contaminants in marine fishes and crustaceans in China (GB 2762–2012). The FSV of Hg is replaced by those of methyl mercury. – The standard values of Mn and Ni are absent in this national food safety standard
