Abstract
Humans and the environment are continuously exposed to a multitude of substances via different routes of exposure. However, the risk assessment of chemicals for regulatory purposes does not generally take into account the “real life” exposure to multiple substances, but mainly relies on the assessment of individual compounds. This report summarizes the different methodologies that are used to assess the toxic effects of mixtures (Chapter 1). It also provides an overview of current legislation in the EU that deals with the safety assessment of chemicals in different matrices and whether, and if so to what extent, the current legislation addresses the toxicological risk of mixtures (Chapter 2). Relevant Guidance Documents from the EU and other countries (USA, Canada) and international organisations (such as the WHO or the OECD) are also included in the review (Chapter 3).

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
