Summary

  • The OECD is advancing a pipeline of over a dozen test guidelines and guidance documents for nanomaterials, with several due for approval in 2025 covering everything from toxicokinetics to intestinal fate after oral ingestion.

  • Graphene is emerging as a priority focus, with urgent gaps identified in characterization parameters and existing test methods found to be inadequate for graphene-specific properties.

  • No legally binding occupational exposure limits exist for nano-objects in any jurisdiction, and measurement instruments for workplace exposure show inconsistent results even across the same model, leaving a critical gap in worker protection.

  • South Korea has proposed a new multi-year project to develop dedicated testing guidelines for nanoplastics, with completion targeted for 2029.

  • AI is being explored as a tool to support exposure modelling for nanomaterials in occupational and environmental settings.

NIA Report on the RAC-72 CLH WG

European regulators are moving toward a Category 1 repeated dose toxicity classification for all forms of synthetic amorphous silica via inhalation, a designation that carries significant compliance implications.Animal studies consistently showed lung inflammation and tissue damage at concentrations well below the threshold that normally triggers a Category 1 classification.The proposal covers all SAS types regardless of how they are manufactured, meaning pyrogenic, precipitated, colloidal, and gel forms are all in scope.Human workplace studies were too compromised by confounding factors to be used either way, leaving animal data to drive the classification outcome.
