Area of Science:

  • Environmental Chemistry
  • Analytical Chemistry

Background:

  • Endocrine Disrupting Compounds (EDCs) pose risks in urban water cycles.
  • Accurate measurement of EDCs is crucial for environmental and public health protection.

Purpose of the Study:

  • To evaluate laboratory performance in quantifying steroid estrogens.
  • To compare analytical methods for EDC detection in diverse water matrices.

Main Methods:

  • Inter-laboratory comparison exercise involving European laboratories.
  • Determination of 17alpha-ethinylestradiol, 17beta-estradiol, and estrone.
  • Analysis of spiked tap water, river water, and wastewater using GC-MS and LC-MS/MS.

Main Results:

  • High competence observed among participating laboratories for steroid estrogen detection.
  • Both Gas Chromatography-Mass Spectrometry (GC-MS) and Liquid Chromatography-Tandem Mass Spectrometry (LC-MS/MS) showed reliable performance.
  • Analytical accuracy and reproducibility were assessed across different water matrices.

Conclusions:

  • GC-MS and LC-MS/MS are equally suitable for analyzing natural and synthetic hormones in water.
  • The exercise confirmed the capability of laboratories to accurately measure EDCs.
  • Standardized methods are effective for monitoring endocrine disruptors in the urban water cycle.
