采用衍生化法-气相色谱串联质谱法,对昆明市饮用水源地水体的天然雌激素雌酮(Estrone,E1)、雌二醇(17 β-Estradiol,E2)、人工合成的炔雌二醇(17α-ethynylestradiol,EE2)和雌三醇(Estriol,E3)浓度进行检测分析。研究发现,E1、E2、EE2和E3的的方法检出限分别为1。98、1。86、2。57和1。93 ng/L。昆明市主城区六个主要饮用水源地(松华坝、大河、清水海、云龙、宝象河、自卫村水库)的4种雌激素浓度均低于方法检出限,表明类固醇类雌激素未检出。
Background Investigation on Steroid Estrogens in the Drinking Water Sources in Kunming
In this paper,derivatization and gas chromatography-tandem mass spectrometry were used to test the concentrations of natural Estrone(E1),estradiol(17β-Estradiol,E2),Estriol(E3)and synthetic ethinyl estradiol(17α-ethynylestradiol,EE2)in the drinking water sources of Kunming.The detection limits of E1,E2,EE2 and E3 were 1.98,1.86,2.57 and 1.93ng/L,respectively.The concentrations of four estrogens in the six main drinking water sources(Songhuba,Dahe,Qingshuihai,Yunlong,Baoxianghe,Ziweicun Reservoir)in the main urban area of Kunming were all lower than the detection limits,indicating that steroid estrogens were not detected.
