Registration Open for ASTM International Symposium on Microplastics

Registration is now open for the ASTM International Symposium on Microplastics Analytical and Reference Standards – Opportunities to Advance Microplastic Science, to be held June 30, 2022, at the Hyatt Regency Seattle (Washington, USA). The symposium is co-sponsored by ASTM’s committees on water (D19) and plastics (D20) and will be held in conjunction with their June standards development meetings.

The primary goal of this symposium is to serve as a mechanism to raise awareness of the various microplastics sampling, preparation, and analysis activities that are occurring in the US and across the globe. It is our hope that this symposium will catalyze creation and adoption of new methods for microplastic analysis that will enable researchers to produce the highest caliber science in this burgeoning discipline.

Appropriate topics may include, but are not limited to:

  • Sampling techniques – ocean collection, water column sampling, filtration and capture methods;
  • Sample processing – biological specimen preparation, natural material digestion protocols, density separation;
  • Analytical analysis – spectroscopy, including IR, Raman, LDIR, pyrolysis/gas chromatography/mass spectrometry, hyperspectral imaging;
  • Reference material development – cryo, jet, and mechanical milling techniques, direct synthesis, ablative techniques such as ultrasound and high-intensity light.
