207b - Exposure modelling in Europe: how to pave the road for the future as part of the European Exposure Science Strategy 2020–2030

Exposure models are essential in almost all relevant contexts of exposure science. To address the numerous challenges that exist, exposure modelling is one of the priority areas of ISES Europe. Therefore, a strategy was developed, focused on this priority area (Schlüter et al., 2022), with four strategic objectives: (1)improvement of models, (2)development of new methodologies and support for understudied fields, (3)improvement of model use, and (4)regulatory needs for modelling. Exposure modellers from a wide range of European countries and institutions, active in the fields of occupational, population and environmental exposure science pooled their expertise under the umbrella of the ISES Europe Working Group on exposure models. This working group assessed the state-of-the-art of exposure modelling in Europe. They developed an inventory of exposure models used in Europe and reviewed the existing literature on pitfalls associated with exposure modelling, in order to identify crucial modelling-related strategy elements. Decisive actions were defined for ISES Europe stakeholders focused on achieving the long-term goal of developing a best practice in exposure modelling. Additionally, to the strategic objectives, the working group developed an action plan and roadmap for the implementation of the European Exposure Science Strategy for exposure modelling. This strategic plan will foster a common understanding of modelling-related methodology, terminology, training and education, as well as future research in Europe, and have a broader impact on strategic considerations globally.
