Abstract
We determined the gastrointestinal absorption of the arsenic in Ironite, a readily available fertilizer, for male hamsters (Golden Syrian), considered to be an excellent model for how the human processes inorganic arsenic. Urine and feces were collected after administering an aqueous suspension of Ironite by stomach tube. In addition, we studied the forms and oxidation states of arsenic in Ironite by synchrotron spectroscopic techniques. The absorption of the arsenic in Ironite (1-0-0) was 21.2% and the absorption relative to sodium arsenite was 31.0%. Our results using XANES spectra determinations indicate that Ironite contains scorodite (AsV) as well as previously reported arsenopyrite (As(−1)). Since the 1-0-0 Ironite is readily available for purchase, its risk assessment for children by professionals is recommended. This is especially important because it is used to fertilize large areas of grass in playgrounds and parks where children play. The absorption of the arsenic in it, the hand to mouth activity of children, and the potential of ground water contamination makes the use of 1-0-0 Ironite as a fertilizer a potential environmental hazard.

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
