Abstract
Research on mercury (Hg) contamination in environmental media around ASGM activities is still required, as a database for the formulation of mercury phasing-out and reduction plans.This paper presents the results of research on the distribution of mercury concentrations in river waters, freshwater fish, and sediments as the impact of ASGM activities in Central Kalimantan.The data used are data set from P3KLL measurements in 1999-2008 and the latest measurement results conducted by the PB3-KLHK Directorate in 2018.Mercury analysis was performed using Mercury Analyzer Hg-5000 cold vapor method and the preparation of test samples in accordance with Standards Japan International (JIS) and Indonesian National Quality Standard (SNI).The results indicate that in most sampling locations, the concentration of mercury in river water was still below the quality standard of class I water on the Government Regulation Number 82 Year 2001 (0,001 mg/L).Still, the value at two locations was higher than the quality standard.Mercury contained in freshwater fish samples from rivers around ASGM was ranging between 0,08 and 0,224 mg/kg.This value is still below the value of metal contamination requirements in fish, according to SNI:7387 2009 (0,5 mg/kg).Mercury content in the sediment is ranging between 0,0291 to 0,45 mg/kg, wherein several locations are above the standard in the Quality Guidelines for Freshwater of Canadian Environmental Quality (CEQ), which is 0,17 mg/kg.

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; both teacher heads agree on what is shown here.
