Abstract

fetched live from OpenAlex

Through 2 sampling times (March and August, 2011), the results of analyzing content of Cd and Pb in sedimentary samples indicated the signs of heavy metal pollution (Cd and Pb) in Vung Thung area, Da Nang city. Specifically, Cd content ranged from 0.54 to 1.58mg/kg (dry weight), some sediment samples was from 1.23 to 2.26 times higher than TEL (threshold effect level; < 0.7mg/kg dry weight) of ISQGs (Interim marine sediment quality guide-lines, Canada). Concerning to Pb, its content was in the range of 18.37 - 87.29mg/kg (dry weight), of which most samples were from 1.13 to 2.74 times as high as TEL (≤ 30.3mg/kg dry weight). In regards to heavy metal content in tissue of oyster and green mussel, cadmium content in both of two species was lower than standard (≤ 2mg/kg wet weight) of Ministry of Health (QCVN 8-2:2011/BYT), however, lead content accumulated in oyster is from 2.21 to 2.56 times higher than the allowed limit of Ministry of Health (≤ 1.5mg/kg wet weight), in green mussel was from 1.01 to 3.28 times as much as the allowed limit. The results from correlation analysis showed that the correlation between cadmium in sediment and in tissues of both species was weak, but Pb content in sediment correlated significantly with Pb content in tissues of both species, specifically, correlation coefficient was equal to 0.76 within oyster and 0.72 within green mussel. Indeed, oyster and green mussel can be used as bio - monitoring to evaluate lead pollution in marine environment.

Full frame distilled prediction

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.
