A Comparison of Antimony in Natural Water with Leaching Concentration from Polyethylene Terephthalate (PET) Bottles
Bibliographic record
Abstract
is one of the trace hazardous compounds in drinking water. We investigated Sb concentration on natural environment such as river, reservoir, groundwater and raw water for bottled water. The natural content of Sb in northern Gyeonggi province in South Korea showed range from 0.00~1.64 g/L. The average of Sb in 47 brands of bottled water was 0.57 g/L on market. As a results of leaching experiment, was leached from polyethylene terephthalate(PET) bottles under storage condition at 35, 45 and 60. Sb concentration was increased from 1.04 to 9.84 g/L under 60 after 12weeks. UV-ray irradiation to bottled water not significantly induced antimony leaching for 14days.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
