IMPACT OF REFINERY EFFLUENT ON THE PHYSICOCHEMICAL PROPERTIES OF A WATER BODY IN THE NIGER DELTA
Open accessAbstract
The physicochemical qualities of a refinery effluent and water and sediment of an effluent receiving water body were investigated.The treated refinery effluent contained very high concentrations of phenol (11.06 mg/l), oil and grease (7.52 mg/l), ammonia (8.52 mg/l), COD (91.76 mg/l), TDS (390.6 mg/l) and phosphate (6.2 mg/l), but low in sulphide, nickel, lead, copper and chromium, which were undetectable.High concentrations of phenol (5.13-16.38 mg/l), oil and grease (10.56-15.23 mg/l), and ammonia (4.31-13.17mg/l) were observed in water and sediment samples respectively, at the point of effluent impact.A high concentration of sulphide (3.74 mg/l) was accumulated in the sediment at the point of impact of the refinery effluent, though it was undetectable in the effluent itself or water sample.The concentrations of these parameters as well as of phosphate, nitrate, zinc and COD declined progressively with distance from the point of impact but were still significantly higher than in control water and sediment in samples 1.5 km downstream from the point of impact.Higher concentrations of the pollutants were recorded in the dry season than rainy season except for phosphate and nitrate, which showed the reverse trend.Nickel, lead, copper, chromium and cyanide were neither detected in the effluent nor impacted water body.

Claims other papers make about this one
Each is checked against this paper’s own text: does it say what the citing paper says it does?
The source backs part of the claim, not all of it — or backs it for a different population, condition or comparison.
In the citing paper
“This is in line with the findings of earlier studies that have attributed the indiscriminate release of wastewater in the inland surface water body to their failing water quality [42,43,44].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
