AB  - A novel sorbent, dihydroxylated polymethylmethacrylate (DHPMM), coated on 
      hollow-fiber membrane, is used for the polymer-coated hollow-fiber 
      microextraction of trace amounts of natural and synthetic estrogens, such as 
      diethylstilbestrol, estrone, 17beta-estradiol and 17alpha-ethynylestradiol, in 
      aqueous samples. In this procedure, estrogens were extracted using the 
      functionalized polar DHPMM polymer with derivatization using 
      N-methyl-N-(trimethylsilyl)trifluoroacetamide followed by gas chromatography-mass 
      spectrometric analysis. The detection limits for estrogens in aqueous sample were 
      between 0.03 and 0.8 ng l(-1) and the calibration curves were linear over the 
      concentration range 0.05-10 microgl(-1) and had correlation coefficients of 
      >0.994. The relative standard deviations (RSDs) were <15% (n = 3). This simple, 
      accurate, sensitive and selective analytical method is applicable to the 
      determination of trace amounts of estrogens in reservoir and potable water 
      samples.
