Sources of γ-HCH in Chinese air at near-surface level and deposited to Chinese soil.
Bibliographic record
Abstract
CanMETOP model was employed to assess the contributions to γ-HCH in Chinese air and soil from four major γ-HCH residual regions, including India, the former Soviet Union (FSU), Europe (excluding the FSU),and China itself in 2005. Modeled annual average air concentrations of γ-HCH at 1.5 m height above ground surface ranged for 10～100 pg/m3 in eastern region, and 1～10 pg/m3 in western region of China. The former was mainly due to Chinese source (30%～80%), while the major of the later was attributable to Indian source ( 50%). The European and FSU sources both mostly contributed to the Chinese northwestern region (10%). The contributions of deposition in China were also different in different area. Chinese source dominated the deposition of γ-HCH in the northeastern area (75%), while Indian source made the largest contribution in northwestern (63%) and southern (67%) areas of China. For whole China, annual total deposition of γ-HCH in 2005 was 691 t, among which, 55.1% was from India, 31.6% was from China, 3.6% was from Europe, and 2.5% was from the FSU.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
