The purpose of this section is to concisely present the conclusions and recommendations of the profile up
front where the reader can easily find them. Briefly summarize the essential findings regarding the
pertinent whole mixture and joint toxic action data, including PBPK or PBPK/PD models. Present the
conclusions regarding the relevance of these data to public health, and the recommended approach for
exposure-based assessments of potential noncancer or cancer health hazards from waste-site specific (or
other) exposure scenarios. Avoid cluttering the summary with string references. References should be
cited only as needed for clarity; some summaries will not need to include any citations. The length of the
summary should be about 1–4 pages.
Additional guidance regarding the formulation and presentation of conclusions and recommendations is
provided in the parts of this guidance document pertaining to Sections 2.3, 3, and 4 of the interaction
profiles.
