摘　　要：四溴双酚A(TBBPA)是一种持久性有机化合物,对环境具有危害性。为研究渤、黄海浮游动物对TBBPA的生物富集,于2016年6—7月在渤、黄海24个站位中采集海水和浮游动物,测定TBBPA浓度、生物量、种类组成和总脂类含量。结果显示,海水和浮游动物中的TBBPA浓度范围分别为0.057~0.607μg/L和0.930~10.165μg/g·d·w,生物富集因子(BAF)范围为1.82×103~63.298×103,表明浮游动物对TBBPA有生物富集能力。生物量、种类组成是影响生物浓度的重要因素,生物量范围为251.663~1 982.541mg/m3(湿重),与生物浓度呈极显著正相关(P<0.01)。桡足类占浮游动物总量比例的降低和季节性浮游动物比例的增加均使BAF显著升高(P<0.05)。小型桡足类(8.34%~22.31%)、季节性浮游动物(9.36%~21.54%)和毛颚动物(6.05%~9.17%)的总脂类含量与BAF呈正相关,表明TBBPA容易富集在脂肪组织中。Tetrabromobisphenol-A（TBBPA）is a new type of Brominated Flame Retardants（BFRs）which is widely used in the global.It is a kind of potential persistent organic compounds,while can accumulate,migrate and transformate in the ecosystem for long distance and time.At the same time,TBBPA,which also has toxicity of cell,immune and liver,will have a serious impact on the environment and organism.The focus of the present study was to research bioaccumulation ability of TBBPA in zooplankton of Bohai Sea and Yellow Sea,China.In the years 2016 June-July,the surface water and zooplankton were collected to measure TBBPA concentration.Moreover,the species composition,biomass and lipid content of particular zooplankton taxa was determined.The results showed that the concentration of TBBPA in surface water and zooplankton are 0.057 2-0.607 3 g/L and 0.93-10.165 g/g·d·w respectively,in Bohai Sea and Yellow Sea.Whether it is visible in surface water and zooplankton,the pollution of coastal areas was serious than offshore areas.The Bioaccumulation Factor,which is 1.82×10^3-63.298×10^3,indicated that Marine zooplankton have obvious abilities of bioaccumulation for TBBPA.Moreover,high concentration of ooplanton is consistent with the high biomass which is 251.66-1 982.54 mg/m3 in the target area（P0.01）.And,high BAF can be linked to the high proportion of meroplankton in that season（P〈0.05）,while the lowest concentrations can be associated with the high percentage share of copepoda in total number of zooplankton（P〈0.05）.It was also observed that lipid content can be more susceptible to accumulating TBBPA.This is indicated the positive correlation between BAF of TBBPA in zooplankton and the lipid content of meroplankton,chaetognathand small copepoda which are 9.36%-21.54%,6.05%-9.17% and 8.34%-22.31%respectively.Adipose tissue is the main site for the accumulation of hydrophobic organic compounds,and also is an important factor for different species which have diffierent bioaccumulation ability.In most cases,gr
