Validation des outils immunotoxicologiques pour l'étude des effets biologiques des contaminants du milieu marin
Bibliographic record
Abstract
Industrial, agricultural, and urban sewages, loaded in various pollutants, draw a chronic ecotoxicological risk on coastal marine ecosystems. For twenty years, the toxic effects of chemicals on the immune system have been studied in all ecological groups, especially in bivalves, to characterize that risk in aquatic ecosystems. To define an operating framework of these immunotoxicological tools, several methodological questions were addressed. Then, was studied the impact of natural endogenous and environmental factors on the immunotoxic signal emitted by a pollutant. Through a French and Canadian framework, two-year surveys in the blue mussel, Mytilus edulis and in the Pacific oyster, Crassostrea gigas, took place in France (Rade de Brest) and gave evidence of the critical role of sex and reproductive cycle on the seasonal patterns of immune parameters, despite the environmental factors of the water column. In the meantime, batches of “in tubo” exposures of blue mussels, in Quebec, at two different seasons, showed also the importance of sex and reproductive cycle in the measurement of the immunotoxic signal, but, most of all, in the immunotoxic sensitivity. Finally, this research built an operating framework for the use of immunotoxicological biomarkers, for chemical risk assessment in coastal marine ecosystems. Furthermore, these findings showed the dramatic role of the studied confounding factors to assess with accuracy the danger of chemicals.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
