Water Toxicity Assessment in the Suape Estuarine Complex (PE-Brazil)
Bibliographic record
Abstract
The Suape estuarine complex (PE, Brazil) is located close to an industrial port complex of Suape which has been responsible for altering the geomorphologic and hydrological conditions of the area. As the industrial port of Suape represents a possible source of pollution through the use and transport of chemical substances, the present research aimed to evaluate if the surface water of the estuarine complex in Suape shows chronic toxicity based on the embryo larval development of the sea urchin Lytechinus variegatus. Six sampling points were established between the estuaries of the rivers Massangana and Tatuoca. Samples of surface water from the area were collected on May, August, October and December of 2007. Chronic toxicity was observed in the six points and it varied depending on the month. The highest level of toxicity was on October when it was detected at all six points. The results showed that the water of the river Massangana was the most probable source of pollution in the area studied during this period.

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.
