The Efficiency of PAH Metabolites Fluorescence Intensity Measurement to Study Pahs Contamination
Bibliographic record
Abstract
The aim of this study was to evaluate the efficiency of fluorescence intensity measurement of PAH metabolites in fish bile (by Fixed Wavelength Fluorescence, FF) to study and assess PAHs contamination in aquatic organism. Nile tilapia (Oreochromis niloticus) was exposed to benzene, fluorene, anthracene, chrysene, and benzo[a]pyrene at non-lethal concentrations. The results showed that the fluorescence intensity and EROD activity were significantly increased with increase in exposure times and PAH concentrations. Moreover, the results of both methods had significantly positive relation. The maximum values were reached in 16 day after exposure. Thus, fluorescence intensity measurement by FF technique could be used as a potential tool for environmental study in the case of PAHs contamination in aquatic environment.

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.
