Abstract
Partition or distribution coefficients (and increasingly referred to as partition ratios) are widely used in environmental science to relate the concentration of a chemical solute in one phase to that in a second phase between which equilibrium applies or is approached. The solutes include organic and inorganic substances; the focus of this paper being on the former. The phases of interest include air, water, soils, sediments, aerosols, and biotic phases, such as lipids, blood, and various tissues. Availability of reliable partition coefficients for contaminants is essential for regulatory and scientific purposes, the general aim being to understand and predict the distribution of the substances in multimedia environmental and biological systems. The history of partition coefficients is reviewed, followed by a brief outline of their theoretical basis and a discussion of methods for determining partition coefficients both empirically and using a variety of predictive methods. It is suggested that ultimately a combination of empirical measurements, quantitative structure–property relationships, and computationally intensive quantum chemical molecular modeling techniques is required to provide accurate data for the large and increasing number of chemicals of commerce that may enter the environment.

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
