Japan Releases Results of Risk Assessment of Priority Assessment Chemical Substances and Future Measures

On March 31, 2025, Japan's Ministry of Economy, Trade and Industry (METI) published the results of its risk assessment (Primary I) of priority assessment chemicals, outlining future actions. The assessment was conducted based on the ""Basic Principles for Risk Assessment of Priority Assessment Chemical Substances under the Chemical Substances Control Law [Revised 3rd Edition]."" Key points include:

1. Results of the primary risk assessment of priority chemicals and planned responses.
2. Priority ranking of chemicals based on human health impact risk.
3. Priority ranking based on ecological impact risk.
4. Data used in assessing human health effects.
5. Data used in assessing ecological impacts.
6. Toxicity information used to calculate the Predicted No Effect Concentration (PNEC) for ecological effects.
7. Ecological assessment coefficients for chemical substance groups.
8. Monitoring data used in the primary risk evaluation.
9. Physicochemical property data used in the assessment.

These findings aim to guide future chemical safety regulations and responses.
