Caracterização Geoquímica Orgânica e Inorgânica de Sedimentos de Manguezais do Estuário São Francisco, Sergipe
Bibliographic record
Abstract
Ecossistemas de manguezais se desenvolvem em regioes litorâneas e possuem caracteristicas intrinsecas, sendo no Brasil considerados areas de preservacao ambiental, porem, impactos antropogenicos associados a especulacao imobiliaria e atividades petroliferas estao alterando o cenario desses ecossistemas. O presente trabalho objetivou realizar a caracterizacao geoquimica orgânica e inorgânica (pH em agua, teor de materia orgânica (MO), analise elementar, determinacao de metais – Al, Na, K, Fe, Cd, Cr, Cu, Ni e Pb) de sedimentos de manguezais do Estuario Sao Francisco, Sergipe. Caracteristicas mineralogicas definiram os sedimentos como de acidez elevada (pH 10 e % MO superiores a 15 % estao relacionados a proximidade das estacoes de coleta a centros urbanos e industriais, caracteristicas intrinsecas da vegetacao nativa e diferentes aportes de biomassa. Os metais Cd, Cu e Ni, em alguns sedimentos, se mostraram acima dos limites referenciados por Threshold Effect Level ( TEL ) e Probable Effect Level (PEL) do Canadian Sediment Quality Guidelines for the Protection of Aquatic Life e do Conselho Nacional do Meio Ambiente (CONAMA), estando associados a atividades antropogenica na regiao e alertando para fins toxicologicos.

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; both teacher heads agree on what is shown here.
