IPCHEM data platform

Successful workshop on developing the IPCHEM data platform to support the assessment of chemical mixtures

On 11 and 12 December 2017 a workshop was held at the EC Joint Research Centre (JRC) in Ispra, Italy, aiming to discuss the further development of the IPCHEM data platform (https://ipchem.jrc.ec.europa.eu) for supporting the assessment of chemical mixtures. A number of selected experts and the European Commission services (ECHA, EFSA, EEA, DG ENVI, DG RTD) as well as representatives form European research projects were invited and present at the meeting.

The European Commission is aiming to have one access point for all chemical occurrence data in Europe. The European authorities EFSA, EEA and ECHA are cooperating on this initiative by contributing relevant data. European projects as for example HBM4EU (https://www.hbm4eu.eu/) will organise their biomonitoring data in the IPCHEM platform.

Jacob van Klaveren from RIVM and Hilko van der Voet from Wageningen University & Research presented the EuroMix project and the EuroMix model platfom. It was seen as a complementary tool to the IPCHEM database. The EuroMix presentations were well received. JRC intends to implement web services to facilitate data access from the EuroMix toolbox, and to provide on their website a link to the EuroMix toolbox for performing mixture risk assessments.

With the IPCHEM platform we expect that data needed for mixture risk assessment will become available in a more coherent manner. It will include dietary and non-dietary chemical occurrence data as well as detailed properties of chemicals.

These developments will certainly boost the discussion on how to maintain the EuroMix tools after the project will end and how to continue to work on the EuroMix concept (risk assessment based on AOP data). It was also discussed how to link EuroMix better to HBM4EU data or how HBM4EU observation might prioritise our next case studies. We will start considering useful links and new case studies soon and plan to discuss these possibilities in the next EuroMix consortium meeting.

JRC will make an official communication of this workshop including the presentations given.

European Partnership for Alternative Approaches to Animal Testing

EuroMix contributed to EPAA Partners Forum: Finding synergies for 3Rs Toxicokinetics and read‐across

On November 21st 2017, partners in the European Partnership for Alternative Approaches to Animal Testing (EPPA) met in Brussels to build synergies on the development and acceptance of Toxicokinetics (TK) and read‐across. The EPAA Partners Forum brought together 33 expert participants from industry and European Commission (EC), along with selected representatives from regulatory agencies and invited researchers from two EU‐funded H2020 research projects (EuroMix and EUToxRisk). Dr. Vikas Kumar from University of Rovira I Virgili (Spain) represented the EuroMix project in this meeting.  Dr. Kumar presented “Toxicokinetics and read across in EuroMix” and discussed how research in EuroMix is helpful for the wider stakeholders and why collaboration is necessary for the society. This EPAA Partners Forum was part of EPAA activities to address one of 6 challenges as a priority i.e. to improve intra and inter sectorial collaboration and coordination. EPAA is a relevant platform to build synergies across sectors, given its multi‐sectoral structure encompassing different business sectors. Besides exchanging information between sectors about their respective research agendas and activities in the sectorial flagship initiatives, the event was meant as an opportunity for the partners to identify possibilities for synergies, receive feedback and present scientific input relevant for EPAA. Discussions revolved around four balanced sessions aiming at covering the whole spectrum of stakeholders working on Toxicokinetics (TK) and read‐across i.e. regulators, the regulated, method developers and downstream users.

At the end of the day, a scientific consensus was achieved on the following four items:

  • TK data play an important role in risk assessment across all industry sectors and are subject to significant research effort by all relevant stakeholders
  • TK data strengthen the read across weight of evidence; TK data should ideally be anchored towards human relevance, preferably generated using in silico and in vitro tools
  • Identification and characterization of Metabolism is a key component of TK assessment in read-across
  • The forum expressed confidence that significantly more progress in TK can be made if collaboration between sectors is enhanced and synergies are captured.

The participants’ discussion was captured by a scientific writer and a scientific publication is currently under preparation.

2nd EuroMix Scientific Advisory Board meeting

The second Scientific Advisory Board meeting in EuroMix was held November 10th 2017 in Ghent, Belgium. The objective of the meeting was to inform the Scientific Advisory Board members on the progress made in the EuroMix project on the test strategy and the tools that will be released for future testing and risk assessment of mixtures. It also aimed to obtain feedback regarding the work carried out and ensure relevance of the test strategy for users in the future.

International Society of Exposure Science 2017

EuroMix activities were presented at the International Society of Exposure Science (ISES) 2017 Annual Meeting in Raleigh, North Carolina, USA, October 15-17 2017

Three members of the EuroMix consortium presented recent advancements in the PBPK modelling approaches and model integration within the EuroMix project during a distinct EuroMix session on „The Role of PBPK Modelling in Holistic Exposure and Risk Assessment – Case Studies and Developments within the EU Project EuroMix” at the world’s largest exposure conference. The session was led by Cecile Karrer and Dr Natalie von Goetz from ETH Zurich. A talk given by Cecile Karrer (ETH Zurich, Switzerland) initiated the session on a new PBPK model for the bisphenol A substitutes BPF and BPS, this was followed by Paul Quindroit (Ineris, France) who presented a new PBPK model for pyrethroids and finally Waldo de Boer (Biometris, The Netherlands) presented and discussed the new features of the integrated model environment for the web-based EuroMix toolbox.

ECPA Residues Workshop 2017




EuroMix efforts on international harmonisation on cumulative risk assessment were presented in a lecture by Angelo Moretto, form University of Milan, partner of EuroMix, at the  “ECPA Residues Workshop 2017, The current and future challenges”, held  in Brussels, 16-17 October 2017. The title of the presentation was ““Looking at harmonisation opportunities – the Euromix project and JMPR considerations” and it was well received by the about 80 attendants from different parts of the world and different sectors (food industry, pesticide producers, regulatory, farmers’ associations) and discussion continued after the session ended. There appears to be a lot of interest in any effort towards harmonization and consistency of approaches to risk assessment of pesticides.
