TRACE METALS IN WATER FROM OLOGE LAGOON, LAGOS, NIGERIA
Bibliographic record
Abstract
The concentrations of Fe, Mn, Cu, Zn, Cd, Pb, and Ni were determined in water of Ologe lagoon on a bimonthly intervals between January 1997 and December 1998. The recorded heavy metal concentrations (except iron) were either significantly lower or within the safety limits of published averages for freshwaters; recommended standards by the EC, Canada, and USSR for the use of fisheries and aquatic life. A higher concentration of Fe reflects the natural sources due to the geology of the catchment soil. Variations in the concentrations of heavy metals in water may be due to local differences in current velocity and distance from the shore line (from sewage source of the residential sector). The level of industrialisation in the study area is very low; hence, contribution of heavy metals from industrial sources on the heavy metal status of the lagoon is minimal.

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.
