[Determination of estrogenic compounds in water of Jiulong River using polar organic chemical integrative sampler].
Polar organic chemical integrative sampler (POCIS) has been recently documented for the detection of polar organic compounds in the environment to achieve a time weighted average concentration. So it is an important complimentary for spot sampling. POCIS was examined for its sampling efficiency for four kinds of estrogenic compounds (EDCs: estrone, 17alpha-ethynylestradiol, 17beta-estradiol, estriol) in this study. The kinetic studies showed an integrative uptake up to 7 d and the sampling rate decreased as the temperature increased( RSD > 12%). As for different concentrations of target compounds, the sampling rate was not affected by the concentrations (RSD < 5%). After laboratory experiments, an environmental field study was performed in Jiulong River. The results showed that there was a relatively good correlation between the measured and calculated values (r2 = 0.7209, P < 0.001). It demonstrated that POCIS can be used in aquatic field systems.
