Sanmen Bay plays a crucial role in economic shellfish aquaculture in China, yet few studies exist on the arsenic speciation of shellfish from this area. In this study, arsenic speciation of 11 cultured shellfish species from Sanmen Bay were analyzed by HPLC/ICP-MS. The results showed that organic arsenic particularly AsB, was the dominant arsenic species, constituting 21 %-71 % of the total arsenic. Conversely, the levels of inorganic arsenic were relatively low, ranging from 0.007 to 0.093 mg/kg, only accounted for 0.2 %-5.7 % of the total arsenic. There was no significant level correlation between inorganic arsenic and total arsenic in Sanmen Bay shellfish, so the concentration of inorganic arsenic did not increase with the total arsenic. Overall, the present study firstly revealed the arsenic speciation of shellfish from Sanmen Bay and also suggested that the proportion of inorganic arsenic should be considered in the revision of arsenic limit values.
三门湾在我国贝类经济养殖中起着至关重要的作用，但有关该地区贝类砷形态的研究甚少。本研究采用 HPLC/ICP-MS 分析了三门湾 11 种养殖贝类的砷形态。结果表明，有机砷，特别是 AsB，是主要的砷形态，占总砷的 21%-71%。相反，无机砷的含量相对较低，范围为 0.007-0.093mg/kg，仅占总砷的 0.2%-5.7%。三门湾贝类中无机砷与总砷之间没有显著的水平相关性，因此无机砷的浓度不会随着总砷的增加而增加。总的来说，本研究首次揭示了三门湾贝类的砷形态，也建议在修订砷限量值时应考虑无机砷的比例。
