Abstract
Two different methods including Hakanson ecological risk index method and Canadian sediment quality guidelines(SQG)for PCBs were used for assessment of ecological risks of PCBs based on the concentration of PCBs in the sediments from different estuaries in China,and source of PCBs and major affecting factors were also studied.Assessment results were very similar which used the above two method.PCBs pollution was the worst in Zhujiang Estuary,followed by Minjiang Estuary,Jiulongjiang Estuary and Yangtze River Estuary.For all the investigated estuaries serious risk threat of PCBs was not exist.Potential risk might occur to some sites of the estuaries.Ecological risks of PCBs in sediment were relatively low in Yellow River Estuary,Yalujiang Estuary and Liaohe Estuary.

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
