European Teratology Society Meeting

The 45th European Teratology Society Meeting was held in Budapest, Hungary on September 4-7, 2017. Elena Menegola and the team at the Univeristy of Milan were awarded during the meeting with „The Teddy Edward’s memorial Prize for Research into Congenital Malformation“ for their work in EuroMix work package 3 on the effects of teratogens on crania-facial morphogenesis.

The ETS (European Teratology Society) was created in 1971 and are dedicated to the prevention of adverse effects on reproduction and development. The core objectives of the European Teratology Society are to stimulate interest in, and promote the exchange of ideas and information about, the causes and prevention of adverse effects on reproduction and development allowing the exchange of knowledge among experts from academia, regulative agencies and industries.

The Teddy Edwards Prize for Research into Congenital Malformations is an  award to the poster or free communication, which best exemplifies the aims of the Society. It’s the main appreciation award assigned directly from the ETS committee.

 

Hazardous Substances Advisory Committee

Dr Marc Kennedy (Statistician at Fera) will give a talk on September 19th to Defra’s Hazardous Substances Advisory Committee (HSAC).

HSAC is considering the issue of combination effects of chemicals, working with others. The HSAC committee is aware that there are a number of ongoing initiatives being carried out in the international arena and has invited Dr Andy Hart and Dr Marc Kennedy to hear about Euromix. Dr Kennedy will give a general introduction to Euromix and some detail on the cumulative and aggregate exposure modelling. Dr Hart will give a second talk in December, in which the broader issues of uncertainty and risk will be covered. Other UK researchers will also present related research at these meetings.

The Hazardous Substances Advisory Committee (HSAC) provides expert advice on how to protect the environment, and human health via the environment, from potentially hazardous substances and articles, including nanomaterials.

WHO Chemical Risk Assessment Network

Jacob van Klaveren will present EuroMix at the 2nd meeting of the WHO chemical risk assessment network that will be hosted by the European food safety authority (EFSA) 20-22 June 2017 in Parma, Italy. This meeting is part of the ongoing WHO-EFSA network activities.

EuroMix Workshop – International harmonisation

Second workshop on international harmonisation on the risk assessment of combined exposures to chemicals

Thon Hotel EU, Rue de la Loi 75, 1040 Bruxelles, Belgium

17 May 2017

The EUROMIX consortium organised the second of a series of workshops to discuss international harmonisation of approaches to the risk assessment of combined exposure to chemicals on 17th May 2017.  The workshop was held at the Thon Hotel EU, Brussels, Belgium.  The 19 participants at the workshop were drawn from a range of geographical and regulatory areas, with risk assessors and risk managers from several continents (Europe, USA, Canada and Brazil) and authorities (DG SANTE, DG ENV, EFSA, JRC, OECD, Codes Alimentarius, WHO, US EPA, US FDA, RIVM, BfR) present.

The main aims of this workshop were to understand current and upcoming legislative needs for cumulative risk assessment of chemicals (with a focus on the diet); how this varies across chemical sectors (e.g. pesticides, additives) and the extent to which this might be harmonized; how this varies across geographical region and the opportunities for harmonization; the role that scientific research, and particularly that of EuroMix, might play in the development and implementation of legislation in this area.

Risk managers in the areas of pesticides, food additives, chemical contaminants and chemicals in general provided perspectives on the need for cumulative risk assessment; practicalities of implementing risk management of combined exposures to chemicals within and across sectors; the degree of precaution necessary in current and future approaches; what do risk managers need from science? Participants in the EuroMix project outlined the approaches they proposed, including tiered assessment, the EuroMix toolbox, and the EuroMix approach to assessing chemical grouping using AOP-wise methods and uncertainty quantification.

Participants reached a number of general conclusions. Currently there is no overarching approach to cumulative risk assessment in Europe (or elsewhere) but work in now ongoing to explore this, for example at OECD and EFSA. Approaches to cumulative risk assessment vary across sectors and with geography. The most common approach for grouping chemicals is based on common structure and/or co-occurrence and/or designed function. EuroMix will explore the implications of different exposure and toxicology choices in grouping chemicals to enable harmonization where appropriate and desirable.

The conclusions of the workshop will be written up in the minutes of the meeting and will be explored further at the 3rd workshop in the series, to be held late 2017 or early 2018.

First EuroMix Workshop on the International Harmonisation of Approaches to the Risk Assessment of Combined Exposure to Chemicals

The EuroMix consortium organised the first of a series of workshops to discuss international harmonisation of approaches to the risk assessment of combined exposure to chemicals over 20-21 October 2016. The workshop was held at the Hammersmith Campus of Imperial College London, the partner tasked with coordinating this activity within EuroMix. The 15 participants at the workshop encompassed wide geographical and regulatory coverage, with scientists from several continents (Europe, North America, South America, Asia, Australasia, Africa) and authorities (EFSA, OECD, JRC, US EPA, APVMA (Australia), FAO, RIVM, BfR) present.

The focused discussions covered a number of the key scientific issues that will need to be resolved to enable international harmonization of the approaches used. Aspects included the importance of explicit and transparent problem formulation, which categories of chemicals should be covered, what is meant by co-exposure, what factors (biological and/or exposure) should determine assessment groups, the role of detailed information on adverse outcome pathways/modes of action and how this might be obtained, whether there was a need to address the possibility of synergy, and probabilistic exposure assessment, including the need for common reporting formats.

Participants identified a number of areas where there was general agreement and those areas where further discussion would be necessary before harmonisation would be possible. The conclusions of the workshop will contribute to developing the agenda for the 2nd workshop in the series, to be held 17th May, 2017.

EuroMix Stakeholder Workshop

Towards Harmonisation of Implementation of Test Strategies for Chemical Mixtures in Europe

The first EuroMix Stakeholders’ Workshop was held on 18 May 2017 at the Thon Hotel EU in Brussels, Belgium.

This workshop was organised to inform stakeholders 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 needs of stakeholders as well as which further steps can be taken to ensure project relevance to them.

In total, 72 participants attended the workshop, 50 stakeholders and 22 representatives from the beneficiaries. The participants came from the European Member States and the associated countries well as the USA, Canada Brazil and Japan.

The programme and presentations of the workshop can be found here.

Stakeholder survey – opinion on tools and concepts

On a daily basis we are exposed to a mixture of multiple chemicals via food intake, inhalation and dermal contact. The risk to human health that may result from this, depends on how the effects of different chemicals in the mixture combine, and whether there is any synergism or antagonism between them. The number of different combinations of chemicals in mixtures is infinite and an efficient test strategy for mixtures is lacking. Furthermore, there is a societal need to reduce animal testing, which is the current practice in safety testing of chemicals.

The EuroMix project will deliver a mixture test strategy and test instruments using novel techniques. The tests will result in data needed for refining future risk assessment of mixtures relevant to different stakeholders. Ultimately, this will provide information for future risk management decisions on the safety of chemicals in mixtures to be taken by the European Commission and the Codex Alimentarius.

More information on the EuroMix concepts and tools can be found in this presentation.

Therefore, we would like to hear your opinion on the tools and concepts under investigation within EuroMixa and are inviting you to participate in our stakeholder survey.

Seventeen questions have been selected to evaluate our concepts and tools acceptance and understandability.

  1. To finalise test protocols for the animal study;
  2. To finalise the discussion on A, B (similar MoA) and A, C (dissimilar MoA) chemicals based on available in vitro test results;
  3. To set the next step in kinetic modelling;
  4. To discuss the concept (retain & refine, infrastructure, AOP-wise testing, modelling approaches, case studies in tier 1 and tier 2);
  5. To discuss and to prepare the first EuroMix stakeholder meeting.

 

EuroMix training

EuroMix project organised training for stakeholders from industry, authorities and NGOs in February-March 2017.

Three training sessions have been organised. The first one was held at the European Food Safety Authority (EFSA) in Parma, Italy on February 21 2017 and twenty-three scientists from different EFSA units participated in the training.

Two sessions were held in Amsterdam, Netherlands on March 15 and 16 2017  for authorities, universities, NGOs and industry. Forty-two stakeholders participated in the training.

The aim of the training was to support understanding of the strategies for testing and risk assessment of mixtures that are developed in EuroMix. The focus was on how Adverse Outcome Pathways (AOPs) and QSAR can contribute to testing and risk assessment of mixtures as well as on how the mixtures can be selected based on exposure and hazard information. The participants also got hands on experience of the MCRA tool for assessment of combined exposures and of QSAR models.

This was a one-day training and the draft training programme is available here.

EuroMix human cohort (WP7) – news

Recruitment of participants to the EuroMix human cohort (WP7) – news

On the 9th of January 2017, The Norwegian Institute of Public Health (NIPH) launched the EuroMix human cohort web page www.fhi.no/euromix (in Norwegian). The objective is to gather all information on the EuroMix human cohort study relevant for both existing and new participants, including the project description, invitation letter, questionnaires and diaries, frequently asked questions (FAQs) and contact information. The web page will also be used for future dissemination of milestones and results.

Furthermore, on the 20th of January 2017, a recruitment campaign was held at NIPH to recruit new participants to join the EuroMix human cohort. With banners and pamphlets, the project group members promoted the human cohort study during an internal meeting for all employees at NIPH. For visualisation, cylinders with “ping-pong balls” represent study participation (white balls = females, orange balls = males). So far, 45 out of 140 participants have been recruited.

The EuroMix human cohort study in short: The main purpose is to study selected biomarkers of exposure and effect to the mixture of interest and their variability in a human cohort of 140 participants (preferably 70 females and 70 males, aged 18-70). The study includes 24-hour food- and cosmetic diaries as well as biological samples collected at the end of the 24-hour period. Selected biomarkers of exposure to the mixture in serum and/or urine samples will be analysed using appropriate and validated state-of-the art analytical methods.
