The discussion centers on the presentation of solubility, which is typically expressed in grams per volume or moles per volume, but NIOSH uses a percentage format. Participants seek clarification on the meaning of this percentage and express a need for reliable sources that explain NIOSH's definitions. There is a consensus that it is essential to refer to NIOSH for their specific definitions and guidelines regarding solubility in percentage terms. The conversation highlights the importance of understanding different units of measurement in occupational safety and health contexts.
