Workshop Publications

This workshop aimed to provide a thorough review of the revised Toxics of Concern (TOC) list. Participants reviewed appropriateness of data sources and how they were utilized, the methodology of the developed chemical ranking system used to prioritize chemicals, and clearly defining the intended uses of the list given its limitations and uncertainty. Guidance was developed to determine a “cut-off” for the full list of prioritized chemicals, by either Best Professional Judgment or a quantitative method, in order to determine which chemicals are Toxics of Concern, Toxics of Potential Concern, or neither. This review was considered a vital piece of the Toxics Subcommittee’s strategy in directing subcommittee activities and efforts, and as commitments in the Toxics 2000 Strategy, specifically refer to reductions and tracking of “Chemicals of Concern.”
