Detection and risk assessment of the toxic heavy metals in four wild freshwater fishes from Yuepu Town, Baoshan District, Shanghai
Bibliographic record
Abstract
Detection and risk assessment of the contents of heavy metals in four wild freshwater fishes from Yuepu Town, Baoshan District of Shanghai were carried out. The contents of Pb, Cd and Hg in the belly, head and liver of Breams, Crucians, Hypophthalmichthys Molitrixes or Grass Carps were determined using a graphite furnace atomic absorption spectrometer for Pb and Cd and an atomic fluorescence spectrometer for Hg. The contamination level of each metal was assessed by Single Indexes and Nemero Multiple Indexes. The results showed that the four wild freshwater fishes were safe to eat because the heavy metal levels in their bodies were below the national limited standards. However, the content of Pb was higher than that of Cd and Hg and the Multiple Factors Indexes of the three heavy metals in the liver were higher than those in other tissues because of the liver's metal-enriching function.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.
How this classification was reachedexpand
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.
