  • Importance of better documentation and utilization of exposure determinants.
  • Requirement for improved understanding and application of industrial hygiene and biological data.

    • Conclusions:

    • Enhanced characterization of exposures, including dermal and ingestion routes, is essential.
    • Incorporating nonoccupational exposures (e.g., hobbies) and multiple chemical effects is crucial.
    • Exploring diverse exposure metrics will improve the accuracy of occupational health studies.
