Abstract
The influence of Montreal Protocol legislation accepted by Polish Authority (in 2002) on concentration halogenated compounds (CFCs) in the atmosphere was observed. We present measurements made on atmospheric concentrations of seven halogenated compounds (freons F-11, F-12, F-113, chloroform, 1,1,1trichloroethane, carbon tetrachloride, and sulphur hexafluoride) between 1997 and 2008 from the densely polluted urban area of Krakow. The trend coefficients are calculated for the mean daily data measurements obtained at the Krakow stations (50oN, 20oE) using weighted regression method. The concentration of F-11, chloroform, 1,1,1-trichloroethane, and F-12 has a tendency to decrease, whereas F-113, carbon tetrachloride, and sulphur hexafluoride tend to increase. The results of the trend coefficient calculations expressed in ppt/year are F-11, -3.2; F-113, +0.4; CHCl3, -1.3; CH3CCl3, -3.5; CCl4, +1.9; F-12, -0.6; and SF6, +0.22. The result of the measurements, particularly after 1 July 2002, shows a decrease in concentration of the mentioned compounds. This suggests that the Montreal Protocol limitations of CFC emissions are respected in Central Europe, especially in Poland, where those limitations have been in place since July 2002.

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 it
