Observation of the quality of Danube water in the Belgrade region based on benthic animals during periods of high and low water conditions in 2002
Bibliographic record
Abstract
The present paper states conclusions about the quality of Danube water in the Belgrade Region based on analyses of the invertebrate community. The investigation was performed during periods of high (May, 2002) and low (October, 2002) water conditions. Meio- and macrozoobenthos were observed. Qualitative, quantitative, and saprobiological analy?ses were performed. The sampling area covered five stations along 66 km of the river. The community was represented by 26 species. Aquatic worms were the principal component of the benthos with respect to both species richness (six species) and abundance (58.39-99.47 % of the total community). Gastropods were also diverse (six species). Snails were found to be subdominant as far as participation in the total community density is concerned. Structure of the benthic community and the saprobity index (S= 2.78-3.43) indicated the presence of organic pollution. No notable differences of estimated environmental quality were observed between a station upstream from Belgrade and one situated below the exit from the broader territory of Belgrade. Since Belgrade is recognized as one of the main contaminants in regard to biodegradable pollutants in the Middle Danube, this finding points to an impressive self-purifying ability of this huge river.

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.
