Mapping Exposure-Induced Immune Effects: Connecting the Exposome and the Immunome

Watch the EXIMIOUS-EPHOR Joint Symposium at IOHA 2021

16 November 2021

You can now rewatch the symposium titled ‘Exposure assessment in the exposome context – need for precise – broad-scope – external exposure assessment’, which was held at the IOHA 2021 international conference (11-15 September 2021). The event was virtually co-hosted by the Korean Industrial Hygiene Association (KIHA) and the International Occupational Hygiene Association (IOHA) in Daegu, South Korea. Themed Bridging Gaps in Occupational Hygiene Development, Opening New Horizons, the conference held its 12th edition to exchange new knowledge about the various facets in which occupational hygiene has been impacted, including within the context of the global COVID-19 pandemic. A record-breaking 1200 occupational health professionals from 62 countries attended the online conference with over 50 break-out sessions being hosted across the entire event.

IOHA 2021 presented an opportunity for EXIMIOUS to join forces with H2020 project EPHOR to set up a joint symposium on exposure assessment in the exposome context and the development of exposome tools for this as part of the European Human Exposome Network (EHEN). Moderated by Peter Hoet (KU Leuven, EXIMIOUS) and Anjoeka Pronk (TNO, EPHOR), the symposium delved deeper into how a more holistic approach to exposure assessment can be developed for broad exposome characterization. Four speakers, Miranda Loh (IOM), Maaike le Feber (TNO), Murali Jayapala (imec) and Jeroen Vanoirbeek (KU Leuven), shared their insights on various dimensions of exposure assessment in relation to occupational health. Looking at a whole range of exposures, including Volatile Organic Substances (VOS), minerals, particles and metals, our understanding of diseases in an environmental and occupational context can be greatly improved in order to also prevent them.


  • Miranda Loh (IOM – EPHOR) | The application of a low-cost sensor box for the assessment of working life exposures – experience from the EU EPHOR project
  • Maaike le Feber (TNO – EPHOR) | Beyond particle detection: development of a sensor that analyses composition of particles
  • Murali Jayapala (imec – EXIMIOUS) | Exposure assessment using spectral imaging techniques – possibilities in EU EXIMIOUS project and beyond
  • Jeroen Vanoirbeek (KU Leuven – EXIMIOUS) | Dermal exposure vs inhalation exposure: what is the relative contribution to the internal dose?

Moderators: Anjoeka Pronk (TNO, EPHOR) and Peter Hoet (KU Leuven, EXIMIOUS)
