Oil Pollutiona and Its Impact on Water Quality in Ibeno Community
Bibliographic record
Abstract
A comparative study on the impact of oil pollution on water quality in both the oil and non - oil bearing communities of Ibeno and Mbo respectively was conducted. The mean concentration of Pb, (0.20 mg/l) Cd (0.1 mg/l), Cr (0.10 mg/l) and Ni (<0.10 mg/l) were above the WHO recommended limits of 0.05 mg/l, (Pb) 0.005 mg/l (Cd), 0.05 mg/l (Cr) and 0.02 mg/l (Ni) for drinking and domestic water quality. The physicochemical properties in both oil (incident zone and non-oil (control zone) trialed below standards. The mean Ph (5.41) for incident zone and Ph (4.73) for control zone were below the recommended range of 6.5-8.5. BOD varied between 0.5 to 20 mg/l in the incident zone and 0.50 mg/l in the control zone. The Do ranged from 2.7 mg/l to 11.6 mg/l in the incident zone and a mean concentration of 6.4mg/l in the control zone whereas WHO (1993) recommended level is 5 mg/l. Turbidity was higher in all samples above WHO recommended level of 5NTU. The mean values for hydrocarbons (range between <0.003-0.004 mg/l for BTEX were generally below some local and international standards (0.01 mg/l for benzene, 0.7 mg/l for toluene). The regulatory limits (0.0002 mg/l) are stipulated by Department of Petroleum Resources DPR.

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.
