Symposium on Contaminants in the Extraction Industry and Their Impact on Consumer Safety

Updated: Oct 5, 2023

Date: October 10, 2023 - October 12, 2023

Event Location: Virtual Only

Organized by: ASTM Committee D37

Solvent Direct manufactures ultra high density dry ice for distribution in Oregon and Washington during the Ferndale Refinery shutdown.


The Virtual Symposium aims to establish a forum for evaluating the existing knowledge and identifying gaps in our understanding of contaminants that may jeopardize consumer health and safety in extracted products. It places a particular emphasis on scrutinizing the origins of contamination, encompassing cultivation, plant absorption, extraction processes, manufacturing, packaging, and distribution, among other factors, and exploring strategies to mitigate these risks.

The insights shared during this symposium will serve as a cornerstone for shaping new standards and specifications relevant to risk assessments rooted in common sources of contamination within the extraction industry. This knowledge will facilitate the development of effective approaches for the detection and reduction of contaminants.

Key topics to be addressed in this symposium encompass, but are not limited to, regulatory thresholds, standards development, the impact of toxicity, testing methodologies, concerns related to vaping, and other pertinent issues associated with contaminants, including:

  • Elemental Impurities

  • Pesticides

  • Microbials

  • Other Contaminants of Interest
