Workshop on Strategies to Evaluate 
Diesel Emissions in the ACES Project

November 6 and 7, 2003
Denver, Colorado

Organized by the Coordinating Research Council 
and the Health Effects Institute

BACKGROUND

The Advanced Collaborative Emissions Study (ACES) is a cooperative, multi-party effort initially proposed by the Engine Manufacturers Association (EMA) to determine the emissions and health effects of new, controlled heavy-duty diesel engines being prepared for market to meet 2007 on-road heavy-duty emissions standards.  For this project, the Coordinating Research Council (CRC) will undertake characterization of emissions and the Health Effects Institute (HEI) will be responsible for health effects assessment.  The overall effort will be guided by a Steering Committee consisting of representatives of all key stakeholders and funders of the effort.  

This workshop, jointly organized by HEI and CRC, represents the initial step to aid in developing an approach and guidelines for emissions characterization and health effects evaluation. The main aims of the workshop were to (a) describe the content of current diesel emissions and how they are expected to change both chemically and physically with new technologies, and (b) discuss and make recommendations on: 

1. Approaches to emissions characterization 
2. Methods of dilution and sampling of exhaust; 
3. Methods for in vitro and in vivo exposures to whole exhaust or components of the exhaust; 
4. Hypotheses for health effects relevant to the emissions to be tested and to future decisions about risk from exposure to diesel exhaust.
