Monitoring programs should generate high-quality data on the concentrations of substances and other pollutants in the aquatic environment to enable reliable risk assessment. Furthermore, the need for comparability over space and time is critical for analysis of trends and evaluation of restoration of natural environment. Additionally, research work and exercises at the European level have highlighted that reliable measurements of estrogenic substances at the PNEC level are still challenging to achieve. The project EDC-WFD “Metrology for monitoring endocrine disrupting compounds under the EU Water Framework Directive” aims to develop traceable analytical methods for determining endocrine disrupting compounds and their effects, with a specific focus on three estrogens of the first watch list (17-beta-estradiol (17βE2), 17-alpha-ethinylestradiol (EE2), and estrone (E1)). Estrogens 17-alpha-estradiol (17aE2) and estriol (E3) will be included to demonstrate the reliability of the developed methods - Mass Spectrometry based method and effect-based methods (EBM) - and to support the requirements of Directive 2013/39/EC, Directive 2009/90/EC and Commission Implementation Decision (EU) 2018/840, hence improving the comparability and compatibility of measurement results within Europe. During the EDC-WFD project four EBM will be deeply investigated in order to improve their rationale use and their support in water quality assessment.

SRT-n11: Metrology for monitoring endocrine disrupting compounds under the Water Framework Directive
(2018)
The Water Framework Directive (WFD) establishes a strategy for the protection and improvement of the aquatic environment and water quality in Europe.
Among chemical pollutants of particular concern are endocrine disrupting compounds (EDCs) due to their environmental and public health effects. In 2013, a class of EDCs - natural and synthetic estrogens - were introduced in the first WFD watch list of priority substances together with their possible methods of analysis and performance requirements.
However, reliable harmonised methods that meet these requirements are still missing and urgently needed.
The project plan to develop traceable measurement methods for the determination of the targeted EDCs and to ensure their transfer to normative bodies.
