Abstract

fetched live from OpenAlex

Distribution and characteristics of heavy metals(Hg、Cd、Cu、Pb、Zn、As、Cr、Ni) in sediment columns from six lakes in Wuhan were investigated. The results demonstrated that the concentrations of heavy metals in lakes in urban area are invariably higher than sediments from lakes in suburb area, and the concentration of heavy metals in top sediment of the urban polluted lakes show some degree of accumulation when compared with deeper sediments in lake sediment columns, while heavy metals show no significant change among sediment columns in suburb lakes. Potential ecological risk index and fresh water sediment quality criteria were then used to assess the heavy metals ecological risk, which leld us to conclude that the potential risk order of elements were Cd Hg As Cu PbZn; Moshu Lake is of the highest potential risk, Jinying Lake ranks the second, while the others have relatively small risk. But, overall, the potential ecological risk of investigated lakes in Wuhan is light, at least not very serious. With reference to the threshold obtained by Canadian ecological databank of sediment baseline, heavy metals in sediments of some lakes of relatively higher risk index may press negative effects to biota within the lake.

Teacher imitation

Not 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.
