ASTM International Announces Workshop on PFAS in Atmosphere

ASTM International’s is hosting a Workshop on PFAS in Atmosphere – Sources, Sampling, and Standards, to be held Nov. 1-2, 2023, in Washington, D.C. The event is sponsored by ASTM International’s air quality committee (D22) and will be held in conjunction with the committee’s November standards development meetings.

This workshop will cover sources, sampling, and standards of per- and polyfluoroalkyl substances (PFAS) from various atmospheres including indoor air, outdoor air, workplace air, and air sampled from chambers during product testing.

While there have been a few PFAS methods developed for water, soils, sediments, biosolids, and biota, there are currently no similar efforts for vapor-phase PFAS in air. There is a need to develop harmonized and consensus test standards that focus on sampling and analysis of PFAS in air. 

Specific topics include:

  1. Sources: Where do PFAS come from?
  2. Sampling (& Analysis): How to ensure good data quality
  3. Standards: What is needed?

Additional information is available from technical chairs Xiaoyu Liu ( and Charles Bevington (
