The California Air Resources Board (CARB) invites you to participate in a public workshop to discuss health effects of indoor exposures to NO2 and impacts of possible updates to the California indoor air quality guidelines for NO2 on public health.
The workshop will be held via Zoom webinar:
Date: May 16, 2023
Time: 9AM to 1PM
Location: Zoom Webinar
Please register for the Indoor Air Quality Guidelines Update workshop webinar. After registering, you will receive a confirmation email with information about how to join the webinar by computer or by telephone.
Purpose of Workshop
The purpose of this workshop is to hear information about the health effects of indoor exposures to NO2, current indoor air guidelines for international agencies, and how updates to the guidelines could improve indoor air quality and benefit public health. Presenters from health agencies and academia will share their perspectives on indoor air quality issues and the development and use of NO2 guidelines. We will also hear from representatives of community groups and non-profit organizations, who will discuss how poor indoor air quality impacts their communities and what factors they consider important for new indoor air quality guidelines.
Background
CARB’s existing 2005 indoor air quality guidelines were developed as part of the 2005 Indoor Air Quality Report to the Legislature. They were based upon CARB’s outdoor standard for a 1hr averaging time, and WHO’s indoor guideline for a 24hr averaging time. These guidelines were one of the first efforts to provide information on safe levels for pollution indoors. Since then, other agencies, most notably Health Canada and WHO, have continued to update their indoor guidelines and adopt lower indoor pollutant levels to protect public health. The Health Canada and WHO guidelines for indoor NO2 levels are significantly lower than CARB’s guideline levels. These examples of updated guidelines from other agencies support the need to reevaluate CARB’s indoor air guidelines.
