RI-URBANS was honored to participate in the 28th meeting of the Joint Task Force on the Health Aspects of Air Pollution, co-organized by the World Health Organization (WHO) European Centre for Environment and Health (ECEH) and the United Nations Economic Commission for Europe (UNECE) under the Executive Body for the Convention on Long-Range Transboundary Air Pollution.

During the two-day virtual meeting held on 20–21 May 2025, RI-URBANS presented recent findings on the short-term health impacts of novel air pollution metrics. These results emerged from two of the project’s key work packages:

• WP2: Focused on long, but non-harmonized time series of air quality and health data

• WP4: Utilized shorter, fully harmonized datasets for more consistent cross-analysis

A key highlight of the presentation was the discussion of particulate matter oxidative potential (OP)—an emerging air pollution metric with strong relevance to public health but still relatively underexplored in policy frameworks. The audience showed high engagement, particularly in relation to OP, posing thoughtful questions and expressing enthusiasm about its potential applications in health impact assessments.
