Analysis of Heavy Metals and Some Physicochemical Parameters in Soil of Major Industrial Dumpsites in Akure Township, Ondo State of South Western Nigeria
Bibliographic record
Abstract
Heavy metals and soil physicochemical parameters were identified as environmental pollutants in some major industrial dumpsites in Akure city of Ondo-State. The pH of the industrial dumpsites ranged from 4.87 to 6.74 with a mean value of 6.34. The organic carbon for the industrial dumpsites ranged from 0.07% to 0.97%, while the organic matter was between 0.13% and 1.68%. The concentration of Zn, Fe, Cu, Pb, Cd, Ni and Cr in µg/g in all the industrial dumpsites A, B, C ranged between 237.60 – 486.00, 174.40 – 499.20, 18.00 – 114.00, 20.60 – 249.20, 1.06 – 2.65, 30.26 – 70.58, and 30.50 – 68.08 respectively. Also the contamination/pollution index of Zn, Fe, Cu, Pb, Cd, Ni, and Cr all the industrial dumpsites. A, B, C ranged between 1.69-3.47, not detected, 0.50-3.17, 0.24-2.53, 1.33-3.23, 0.86-2.01, and 0.31-0.68 respectively Pearson Correlation indicated that Fe, Zn, Ni and Pb were highly significant (p < 0.01).
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
