Abstract

fetched live from OpenAlex

The persistence of 17alpha-ethynylestradiol in agricultural soil was established in laboratory microcosm studies. The hormone was rapidly dissipated in loam, sandy loam, and silt loam soils under a range of moisture and temperature conditions. Dissipation of 17alpha-ethynylestradiol correlated closely with removal of total estrogenicity determined with a recombinant yeast bioassay, indicating that extractable estrogenic transformation products did not accumulate. The stability of 17alpha-ethynylestradiol in sterile soil, decreased removal in the absence of oxygen, and the response of dissipation kinetics to variation in temperature and moisture suggested that the removal was microbially mediated. We conclude that 17alpha-ethynylestradiol is rapidly dissipated in agricultural soils under a range of conditions typical of a temperate growing season.

Full frame distilled prediction

Teacher imitation

Not 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.
