Announcing a Conference on

Susceptibility to Inhaled PollutantsSEPTEMBER 29-OCTOBER 1, 1987

The Hilton Hotel, Williamsburg, Virginia

The Clean Air Act requires that susceptible individuals be protected as well as the generalpopulation. To explore some of the implications of this problem, this conference will focus on theresponsiveness of the respiratory system to inhaled pollutants. Participants will include leadingscientists from various fields: inhalation toxicology, biochemistry, engineering, pulmonary medi-cine, epidemiology and statistics. Discussion topics include:

* Basic Detrminants of Susceptibility* DemographIcs of Susceptible Populatons* Factors Affecting Pulmonary DosImetry* Asthma and Non-Asthmatic Models of Susceptibility* Major Aras of Uncertainty and Critical Research NPeds

The conference will be co-chaired by Dr. Mark J. Utell, Professor of Medicine and Toxicologyand Co-Director, Pulmonary and Critical Care Unit, The University of Rochester School ofMedicine and Dr. Robert Frank, Professor of Environmental Health Sciences and Deputy Directorof the Environmental Health Sciences Center, School of Hygiene and Public Health, The JohnsHopkins University.

It is being sponsored by the American Petroleum Institute, American Lung Association,American Society for Testing and Materials, Environmental Protection Agency, Electric PowerResearch Institute, Health Effects Institute, and The Natural Resources Defense Council.
