Project at a Glance

Title: Workshop on a California ambient air quality standard for inhalable particles.

Principal Investigator / Author(s): Wesolowski, Jerome J.

Contractor: Air and Industrial Hygiene Laboratory, California Department of Health Services

Contract Number: A8-094-31

Research Program Area: Health & Exposure

Topic Areas: Health Effects of Air Pollution


The purpose of the workshop was to bring together a small group of experts on health effects and monitoring of inhalable particles to draft a report concerning a possible California inhalable particle air quality standard to be sent to the Department of Health Services Air Quality Advisory Committee and the California Air Resources Board for their consideration.

There were 43 attendees at the workshop. They consisted of three groups:

1. A Working Committee on an Inhaled Particle Standard. The committee members were chosen by mutual agreement of the Department of Health Services and the Air Resources Board. The role of the working committee, and thus the output of the workshop, is the attached written report summarizing their conclusions concerning a possible California air Quality standard for inhalable particles.
2. A group of experts on medical and monitoring aspects of inhaled particles chosen by mutual consent of the Department of Health Services and the Air Resources Board. The experts' role was to bring forward pertinent information and to answer specific questions posed by committee members.
3. Invited Auditors and Discussants.

The attached report has been sent with appropriate cover letters to all attendees, members of the Department of Health Services' Air Quality Advisory Committee, members of the Air Resources Board, members of the Air Resources Board's Research Screening Committee, and copies are available to anyone interested in the workshop proceedings. The report of the working committee includes background information, recommendations, and various appendices, including the workshop agenda and a list of attendees.
