Ten perfluoroalkyl acids (PFAAs) were measured in seafood collected from Bohai Bay, China in 2010. The summed concentrations of the PFAAs were in the ranges of not detected to 194 ng/g dry weight and 4.0 to 304 ng/g dry weight for invertebrates and fish, respectively. The levels of perflurooctanesulfonate (PFOS) and perfluorooctanoic acid (PFOA) in the seafood were lower than those from North America, the Mediterranean Sea, and South Korea. Living habitat, trophic level, and feeding habits had important impacts on the bioaccumulation and distribution of PFAAs in the seafood. The species at higher trophic levels had the potential to accumulate more PFAAs than benthic invertebrates. Tidal-flat organisms tended to accumulate more PFOA than PFOS, whereas the opposite was seen for shallow-water species. For all the species, PFOS and PFOA were partitioned preferentially in the liver or viscera. Risk assessment indicated that the current level of PFAAs in the seafood of Bohai Bay does not represent an immediate source of harm to public health.
2010 年在中国渤海湾采集的海鲜中检测到了十种全氟烷基酸 (PFAAs)。PFAAs 的总浓度在未检出到 194ng/g 干重和 4.0 到 304ng/g 干重之间，分别为无脊椎动物和鱼类。海鲜中的全氟辛烷磺酸 (PFOS) 和全氟辛酸 (PFOA) 水平低于北美的水平、地中海和韩国。生活栖息地、营养水平和饮食习惯对海鲜中 PFAAs 的生物积累和分布有重要影响。处于较高营养水平的物种比底栖无脊椎动物更有可能积累更多的 PFAAs。潮滩生物体内的 PFOA 比 PFOS 更容易积累，而浅海物种则相反。对于所有物种，PFOS 和 PFOA 优先分配到肝脏或内脏中。风险评估表明，目前渤海湾海鲜中的 PFAAs 含量不会对公众健康造成直接危害。
