Mercury Contamination along the Mekong River, Cambodia
Bibliographic record
Abstract
Sampling and analysis of mercury was conducted along the Mekong River from central to northern Cambodia. One of 10 Irrawaddy Dolphin livers analyzed had a high concentration of mercury (67 µg/g). The mercury content of fish at Kratie was on average 99 ng/g (n=160) but in some species it was up to six-fold higher. People located in a sample drainage basin with gold mines, on average, had more mercury in their hair (4.4 µg/g) than those living along the northern portion of the Mekong River (3.4 µg/g). Males, on average, exhibited higher mercury in their hair than women (5.2 vs 3.1 µg/g, respectively). Individuals had as much as 23 µg/g of mercury in their hair. While mercury levels in hair and fish were elevated and gold mines were one source, there are other unknown sources and further analysis is required to determine what sources of mercury are manageable in Cambodia.

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.
