METAL CONCENTRATION STUDY IN A POPULATION LIVING IN THE VICINITY OF AN OIL REFINERY
Bibliographic record
Abstract
The aim is to evaluate the exposure of Slavonski Brod citizens to metals from the environment: lead, cadmium, mercury, arsenic, nickel, manganese and thallium. Concentrations of Pb, Cd, Hg, As, Ni, Mn and Tl were analyzed in the whole blood and/or serum, urine and hair of 40 examinees from Slavonski Brod. According to "wind rose" data and the vicinity of the oil refinery, examinees were divided in two groups: Group I with 20 examinees (17 females/3 males) and Group II with 20 examinees (13 females/7 males). Metals were analyzed using inductively coupled plasma mass spectrometry. Analysis accuracy was confirmed with reference samples. The difference between the groups was tested using the Mann-Whitney U test. Reference values were taken from German commission for biomonitoring, biomonitoring studies with Canadian examinees, Mayo Medical Laboratories reference values, USA and London Pathology, and Laboratory Medicine from Canada. There was no difference in age between the groups (Group I: x = 48.2; SD 15.2; Group II: x = 50.7; SD 21.7; z = -0.590; p = 0.555). Statistically significant differences were determined in As in blood (Group I: M = 2.10; Group II: M = 3.20; z = -3.414; p = 0.0006), in Tl in blood (Group I: M = 0.012; Group II: M = 0.021; z = -2.37; p = 0.018), in Pb in urine (Group I: M = 0.71; Group II: M = 1.20; z = -2.12; p = 0.034) and in Mn in urine (Group I: M = 0.19; Group II: M = 0.11; z = 2.04; p = 0.042).

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.
