The Health Effects Institute


Understanding the Health Effects of
Air Pollution: Recent Advances
to Inform EU Policies

Co-organized by the European Commission,
the World Health Organization Regional Office for Europe,
and the Health Effects Institute

Brussels, Belgium
Auditorium, Madou Tower, Place Madou

30-31 January 2013


MEETING GOALS

The European Commission (EC) has declared 2013 as the "Year of Air" to bring focus on the importance of clean air for all and action to improve air quality. Currently, the EC, in partnership with the World Health Organisation (WHO) Regional Office for Europe, is reviewing the latest health science on major air pollutants as a key step in evaluating whether to update Europe’s Air Quality Limit Values. The three main workshop goals were to:

  • Describe the approaches to evaluating evidence for setting environmental limit values in Europe and for establishing air quality standards in other regulatory settings, e.g., the United States.
  • Present the latest findings on the health effects of Air pollution, giving consideration to such key topics as whether there is a "safe" concentration below which no adverse effects are observed for some pollutants, whether the toxicity of airborne particulate matter (PM) differs by source and composition of the particles.
  • Summarize uncertainties in the current scientific evidence, and identify key areas for further research.

This workshop was followed on 31 January by a separate briefing to the European Parliament and policy makers (see announcement at the bottom of this page). The briefing summarised the latest science from WHO and others on major air pollutants such as particulate matter, ground level ozone and nitrogen dioxide, as the basis for discussion on the policy implications of the results.

New research results on effects of PM, NO2 and ozone on health
Chairs: Jonathan Samet, University of Southern California and Elizabet Paunovic, WHO Regional Office for Europe
What new research results have emerged on associations between specific components of the air pollution mixture and adverse health effects, and at which levels are effects observed? We will review evidence on the short-term and long-term effects of air pollution on health, with a focus on cardiovascular effects, but also addressing emerging evidence on other effects, such as developmental and reproductive outcomes. In addition, it is important to know whether adverse health effects are occurring below the current standards. New research may provide further insight into the concentration response functions for the associations between key pollutants and specific health outcomes, to determine whether and how effects at higher concentrations can be extrapolated to lower concentrations.

New research results (continued)

Can we identify either specific sources, sizes, or constituents of PM that are associated with adverse health effects?
Session Chairs: Bert Brunekreef, Utrecht University and Frank Kelly, King’s College London
Studies of PM chemical composition, fine and ultra-fine PM, diesel exhaust, black carbon, and other aspects of PM composition will be the focus of this session. A key theme will be whether the contributions to mixture toxicity of specific sources can be characterized. The session will also address the general limitations of current research approaches (both epidemiologic and toxicologic) for answering questions about the toxicity of specific constituents.

In wrapping up the workshop, we will summarize the evidence presented: (1) Is there a safe threshold? (2) Can we identify which components are more toxic? (3) Can we measure benefits of AQ improvement? (4) How strong is the evidence for emerging health effects such as neurological and developmental outcomes? In addition, we will discuss remaining uncertainties and priorities for future research.
