【摘要】 应用UPLC-MS-MS,对洱海表层沉积物和5种鱼类(白鲢、鲤鱼、鲫鱼、白条鱼和太湖短吻银鱼)样品中TBBPA(四溴双酚A)的质量分数进行了测定.结果表明,洱海表层沉积物中w(TBBPA)(以干质量计,下同)为21.06～52.72 ng/g,平均值为37.72ng/g,呈西部、南部和北部湖区明显高于中部和东部湖区的分布特征,其分布受所处区域的经济发展水平和生活生产状态等影响.白鲢、鲤鱼、鲫鱼、白条鱼和太湖短吻银鱼肌肉中w(TBBPA)平均值分别为13.53、8.20、8.86、7.55和10.87 ng/g,w(TBBPA)与鱼的体长度特征无关,可能与鱼类的食性、所处营养级有关.在鱼体的内脏器官中,肾脏中w(TBBPA)最高,平均值为7.64ng/g;其次为鳃和肝脏,分别为7.07和5.68 ng/g;卵巢和精巢中没有检测到TBBPA的存在.与国内其他地区相比,洱海表层沉积物中w(TBBPA)呈较低水平,鱼体中w(TBBPA)为中等水平.更多还原

【Abstract】 The content of TBBPA(Tetrabromobisphenol-A) in the surface sediment and five different kinds of fish from Erhai Lake was analyzed by UPLC-MS.The analyzed results showed that TBBPA in the surface sediment was in the range of 21.06-52.72 ng/g and the average concentration was 37.72 ng/g.This indicated that TBBPA concentrations in the surface sediment samples collected from the west,the south and the north were higher than those from the middle and the east,where concentration is greatly affected by the economic development and the human activities.The concentrations of TBBPA in muscle tissues of silver carp(Hypophthalmichthysmolitrix),carp(Cyprinus carpio),crucian(Carassius auratus),white fish(Hemiculter leucisculus) and anchovies(Neosalanx tangkehkeii taihuensis) were 13.53,8.20,8.86,7.55 and 10.87 ng/g,respectively.No relations between the concentration of TBPPA and the weight and size of fish were found throu the statistical test.In selected fish tissues,the highest concentration of TBPPA,7.64 ng/g,was found in kidney,while the inferior concentrtrations were detected as 7.07 and 5.68 ng/g in gill and liver,respectively.The was not TBBPA in the spermary and ovary.In summary,the contamination caused by TBBPA in the surface sediment of Erhai Lake was lower,while the situation was similar in fish tissues,compared to other domestic areas.更多还原
