A gathering of leading scientists, policymakers, and industry representatives at the Institute of Natural Sciences in Brussels on February 25th – 26th marked the Final Scientific Conference of the European Research Cluster to Understand the Health Impacts of Micro- and Nanoplastics (CUSP). The two-day event provided a platform to discuss the latest research on micro- and nanoplastics (MNPs), their potential health impacts, and the future direction of policy and research in this field.
The conference represented the culmination of four years of collaborative work under five EU-funded projects—AURORA, IMPTOX, PlasticsFatE, PLASTICHEAL, and POLYRISK. Each project presented its key research outcomes:
- AURORA studies MNP exposure in early life, examining their ability to cross the placental barrier and their potential effects on fetal development.
- IMPTOX investigated interactions between MNPs, environmental contaminants, and allergens, exploring possible links to immune system disorders.
- PlasticsFatE analyzed the movement and accumulation of MNPs in the human body, with a focus on occupational exposure risks.
- PLASTICHEAL assessed long-term health effects, particularly the role of MNPs in inflammation and genetic damage.
- POLYRISK explored the impact of inhaled and ingested MNPs on the immune system in everyday environments.
A recurring theme in discussions was the challenge of developing standardized methods to detect and measure MNPs in biological and environmental samples—an issue that continues to impede regulatory progress.
The second day of the conference focused on how research findings can inform policy. Steffen Foss Hansen (PLASTICHEAL) introduced the third CUSP policy brief, which outlines recommendations for reducing MNP exposure and improving monitoring. Lively discussions addressed methodologies for exposure measurement, risk assessment, and data harmonization, with a strong emphasis on the need for standardized research protocols.
A final panel discussion, moderated by Jane Muncke (AURORA), brought together representatives from the European Commission, industry, and research institutions. Topics included Europe’s Zero Pollution Action Plan, biodegradable plastics, and regulatory measures to limit MNP exposure.
Despite significant progress, researchers acknowledged that knowledge gaps remain, particularly concerning long-term health effects, exposure pathways, and effective mitigation strategies. CUSP scientists called for further investment in standardized detection methods and increased collaboration between research and regulatory bodies.
The conversation continued at the CUSP Final Policy and Stakeholder Meeting on February 27, where policymakers, scientists, civil society and industry representatives discussed the evolving policy landscape and the implementation of the forthcoming CUSP Research Roadmap (2026-2030). The event emphasized the importance of harmonized risk assessment frameworks and continued interdisciplinary cooperation.
While the CUSP research cycle is reaching its conclusion, its findings are expected to influence future policy and regulatory measures concerning MNP exposure. The conference highlighted the necessity of evidence-based policymaking and ongoing research to better understand and address the potential health risks posed by MNPs, ensuring a science-driven approach to environmental and public health policy.
The AURORA project will continue until 2026, and its ongoing research updates will be shared via its website and social media channels.
