Assessment of Physicochemical Parameters of Soils from Selected Abattoirs in Port Harcourt, Rivers State, Nigeria

Wastewater samples were collected from an oil industry at the point of discharge for a period of two years, from January 2018 – December 2019. The wastewater samples were analyzed for different physicochemical parameters such as temperature, turbidity, total dissolved solids (TDS), total suspended solids (TSS), conductivity, pH, alkalinity, salinity, total hydrocarbon content (THC), biochemical oxygen demand (BOD) and chemical oxygen demand (COD) to examine their conformity to fulfill requirements as recommended by World Health Organization (WHO), Federal Ministry of Environment (FME) and Drinking Water Association (DWA). The results indicated that all the parameters in the discharged wastewater were within acceptable limits of the regulatory bodies. The field data showed that the investigated firm conformed to the law by carrying out proper procedures before discharging the effluents into the public drain and river. Therefore, the release of wastewater from the industry doesn't constitute a danger to the environment as well as aquatic organisms.

The levels of physicochemical properties of Mini Whuo Stream in Port Harcourt, Rivers State, Nigeria was evaluated. The physicochemical parameters were analyzed using standard conventional procedures. The average values recorded for the physicochemical parameters during the months of investigation were in the range; temperature; 30.00±0.42-30.26±0.83oC, with all-round mean of 30.14±0.47oC, pH; 6.22±0.33-6.42±0.25 (6.29±0.29), electrical conductivity; 146.01±74.04-147.26±75.13µS/cm (146.58±74.69 µS/cm), total alkalinity; 61.63±6.37-62.20±6.41mg/L (61.91±6.41 mg/L), sulphates; 109.67±51.34-110.67±51.88mg/L (110.22±51.81 mg/L), nitrates; 12.20±2.38-12.60±2.86mg/L (12.31±2.65 mg/L), turbidity; 49.32±1.49-50.18±2.02 NTU(49.83±1.55 NTU), TDS; 74.20±36.43-75.61±37.50 mg/L (75.00±36.81 mg/L), TSS; 27.14±2.12-28.37±0.78mg/L (27.64±1.89 mg/L), chlorides; 15.17±2.90-15.66±2.70mg/L (15.34±2.65 mg/L) and salinity; 24.36±4.83-24.82±4.97mg/L (24.66±4.78 mg/L). The evaluation of the physicochemical parameters showed that the Mini Whuo Stream has been contaminated due to human activities within the stream and therefore adequate measures should be taken to forestall the present situation of the stream in order to mitigate any possible increase in deterioration of the studied physicochemical parameters in the stream beyond acceptable limit.

Physicochemical Properties Of Soils

Some physicochemical properties were assessed in soils within steel welding and fabrication workshops in Port Harcourt, Rivers State, Nigeria. The study was carried out between May to November, 2020. The physicochemical parameters were determined using standard conventional methods of analysis to ascertain the different levels of the selected physicochemical parameters in the studied environment. The results obtained within the months revealed that pH average range was between 6.8±0.08-7.1±0.05, the electrical conductivity average range was between 65.25±0.83-76±0.71µs/cm, percentage organic carbon was within average range of 0.396±0.001-0.525±0.001%, percentage soil organic matter was in the average range of 0.682±0.002-0.904±0.002% and for particle size analysis, percentage sand was in the average range of 75±0.71-79±0.71%, percentage clay was in the average range 9.25±0.83-11±0.71% and percentage silt was in the average range 10.75±0.43-14±0.71% for the Egbelu, Elioparanwo and Saint John soils respectively. Observation from the nature of occurrence of the physicochemical parameters in the steel-welding and fabrication workshops showed that that the steel-welding and fabrication has not yet influenced the level of the physicochemical parameters in the soils studied.
