Abstract
The content of heavy metals in 118 commodity organic fertilizer samples which collected from 10 districts and produced by different raw materials were analyzed.The results showed that the average contents of Cd,Hg,Pb,Cr,As,Zn,Cu,Ni were 0.600,0.120,7.34,84.30,9.45,202.91,91.06,11.01 mg/kg respectively.The average content of heavy metals was relative higher in commodity organic fertilizer of Henan,Hubei,Shanghai;the average Cr content in Inner Mongolia fertilizer samples and average Zn content in Guangxi fertilizer samples was 20.32,51.36 mg/kg respectively,which was lower than average Cr,Zn content of all fertilizer samples.The commodity organic fertilizer samples produced by pig manure had the highest heavy metal content.In reference to the limit indexes of heavy metals in commodity organic fertilizer in China,heavy metal limitations standard in Europe and heavy metal limitations standard of compost in Canada(Category A and Category B),Cr exceeded all those four limitations standard;As,Cd could only meet the Category B of Cananda limitations standard;Cu,Zn exceeded the limitations standard of European and Category A of Cananda;Hg exceeded the Category A limitations standard of Cananda;Pb exceeded the limitations standard of Chinese;Ni could meet all these four limitation standards.

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
