“…TPH showed widest variation in concentrations for sediments and crab in all the stations sampled, while PAH showed the least variation which showed similarities with Ighariemu et al, (2019). The low hydrocarbon concentrations in the sediments are lower than the values gotten by Ediae et al, (2020). C. armatum accumulated hydrocarbon in TPH as showed in Fig.…”

“…Most of the detected PAHs were of petrogenic origin, which means that anthropogenic exercises were influencing PAH concentrations (Olayinka et al, 2019). Ediae et al, (2020) investigated sediment sampled obtained from Bodo community in Ogoni Land, Niger Delta for physicochemical parameters, heavy metals, TPH, PAH, total heterotrophic bacteria (THBC), and fungi (THFC) using standards methodologies. The heavy metals profile revealed Fe > Cr > Zn > Ni > V in decreasing order while TPH and PAH concentrations were 30,797 and 52.12 mg/kg, thus exceeding the target and intervention values of 50 and 5,000 mg/kg, respectively of the Environmental Guidelines and Standards for the Petroleum Industry in Nigeria (EGASPIN), (2002) which also adversely affected the microbial proliferation in the sediment.…”

Food security is hinged on quality and integrity of the surrounding environment. Food quality and security of coastline communities are tied to the constituents of benthic organisms in the area. This study assessed the heavy metals and hydrocarbons status of sediment and crab (Cardisoma armatum) in Amadi Creek in Port Harcourt. Sediment and crab samples were collected from five stations along a 10 km transect for four months. The heavy metals results for sediment showed the following: Zn (18.624 ± 1.254), Pb (0.791 ± 0.072), Cd (0.031 ± 0.012), Cr (3.323 ± 1.079), Ni (1.848 ± 1.329) and V (0.067 ± 0.102 mg/Kg). The heavy metals ranges in the crab were Zn (20.838 ± 7.803), Pb (0.000 ± 0.000) Cd (0.004 ± 0.014), Cr (0.500 ± 0.239), Ni (1.181 ± 0.562) and V (0.055 ± 0.112 mg/Kg). Hydrocarbon results for sediment were TPH (10.020 ± 11.255), PAH (1.377 ± 1.587 mg/Kg), while the crab had ranges of TPH (1.732 ± 2.235) and PAH (0.003 ± 0.007 mg/Kg). The results were within regulatory permissible limits of EGASPIN and WHO. ANOVA at p>0.05 indicated no significant spatial difference between the heavy metals and hydrocarbon concentrations in the sediments and crab at the various stations along the transect. Sediment heavy metal Ecological Risk Assessment revealed that contamination degree and pollution load index were < 1 (indicating no pollution); geo-accumulation index was grade 0 (unpolluted), individual potential risks and potential ecological risk index were < 40 and < 150 respectively (indicating low ecological risk). Sediment to biota transfer factor indicated that Zn was the only heavy metal biomagnified in the crab. Human health risk assessment of the heavy metals in the crab was less than 1 indicating no obvious health risk for cancer over a lifetime of exposure.

“…Furthermore, the study unveiled that oil spills can influence fishing activities, leading to economic consequences for fishermen and their households. Oil pollution in Ogoni Land, Nigeria, impacts microbial diversity with worrisome levels of total petroleum hydrocarbon, polyaromatic aromatic hydrocarbon, iron, chromium, and nickel (Ediae et al, 2020). Extremely relevant to the ecological state, there is a calm necessity for major changes in the approach to address this issue, with importance to the pollution of the soil and water bodies due to the oil leakages and further exposure to toxic agents (Madu et al, 2018).…”

This work documented the effects of oil spills on the aquatic environment by analyzing changes in oil density, water chemistry and species abundance for 15 days in two locations in the Niger Delta. The main rationale was to assess the oil spill's environmental implications and determine the measures that should be implemented. Samples collected daily enabled measurements of the oil content, pH, and dissolved oxygen (DO) on the water surface. Key equipment included spectrophotometers for oil concentration analysis and multiparameter water quality tools for pH and DO measurements. Statistical tools such as regression analysis and ANOVA were employed to evaluate the data. Results indicate a significant decline in oil concentration at both sites. The results of Site A were reduced from 250 µg/L to 170 µg/L, having a regression slope of -5.33 µg/L per day (p < 0.01). Site B's concentration dropped from 320 µg/L to 250 µg/L, with a slope of -4.67 µg/L per day (p < 0.01). Water quality also deteriorated, with Site A’s pH dropping from 7.8 to 6.4 and DO from 8.5 mg/L to 7.1 mg/L. Site B exhibited similar trends, with pH decreasing from 7.9 to 6.5 and DO from 8.6 mg/L to 7.2 mg/L. The results of the ANOVA analysis indicated that the fish population significantly declined at both sites and to this extent, Site A lost eight kinds of fish while Site B lost only 10(p<0.01). Therefore, the study found that the oil spill adversely impacts water quality and the nature of various organisms. These discoveries would help in the current state of knowledge by quantifying the effects of oil spillage and proposing an improved approach to environmental management, which includes but is not limited to effectively mitigating the effects of oil spillage by increasing the monitoring of the effects and rendering timely remediation solutions, and engaging various stakeholders, enforcing strict measures and constantly monitoring the environment.

“…Some studies in the Niger Delta region of Nigeria have linked water contamination with flowing rivers that has been contaminated with heavy metals and unsuitable physico-chemical character from industrial waste [6]. Water also has great potential in transmitting diseases when contaminated [7]. Over the last 5 decades, oil exploration activities have introduced about 3 million barrels of oil into the environment in Niger Delta [8].…”

Aim: This study aimed to assess the quality of drinking water in some hydrocarbon-impacted Ogoni communities. Study Design: The study employ a cross-sectional and analytical design using stratified sampling method. Place and Duration of Study: Department of Medical Laboratory Science of Rivers State University, Giolee Global Resource Limited and Environmental Consultancy Services between March 2020 and March 2021. Methodology: Water samples were collected from (20 hydrocarbon- impacted communities) in the 4 Local Government Area (LGAs) of Ogoni land. These water samples were analyzed to determine the physicochemical, bacteriological, heavy metal and total petroleum hydrocarbon (TPH) parameters using standard methods and operational procedures. The data obtained were subjected to descriptive statistical analysis. The general linearized model (GIG) was used to generate analysis of variance (ANOVA) mean and standard error and arrange, statistically significant was set as p-value of .05 (95% confidence limit). Pearson correlation test was used to calculate the correlation between TPH, Heavy metal, and physicochemical parameters in hydrocarbon and non-hydrocarbon impacted communities. All statistical analyses were performed using GraphPad Prism (Version 8). Results: The results obtained for physicochemical parameters were pH 4.3±0.8 mg/l, EC 0.03±0.05 mg/l, DO 5.5±1.6 mg/l, Temp 25.0±0.0 mg/l, Mv 0.32±0.27 mg/l, Nitrite 0.0058±013 mg/l, Nitrate 0.1530±158 mg/l. These results were all below the recommended standard for Nigeria standard of drinking water quality (NSDWQ) and World Health Organization (WHO). The bacteriological analyses were carried out using multiple tubes technique (Most Probable Number), total coliform count, (TC), total heterotrophic count (THBC) and total fungal count (TFC). The results obtained were 0.941±2.397 cfu/ml, 89.3±176.6 cfu/ml, 297.8±144.4 cfu/ml, and 0.32±0.84 cfu/ml respectively. The p-values for TFC (<0.0002) were statistically significant. Heavy metal profiling was: Cr 0.194±0.320 mg/l, Cd 0.469±0.569 mg/l, Cu 0.211±0.348 mg/l, Pb 0.0336±0.20 mg/l, Fe 0.705±1.244 mg/l, Zn 0.258±0.249 mg/l, respectively. Generally, the concentration of heavy metal increased more than the standard recommended by NSDWQ and WHO except for Zn 0.255±0.249 mg/l, and Cu 0.56±0.50 mg/l, that is slightly lower than the acceptable limit recommended by WHO and NSWWQ. The sequences of heavy metal concentration were in Cd > Cr> Pb>Fe> Cu.>Zn. The statistical significance values for Pb p=.003 and for Zn p=.009 were statistically significant. The concentration of TPH were (349.9 ppm/ml) higher than the recommended values for NSDWQ and WHO. Conclusion: The findings in this research reviewed a worrisome level of TPH and Pb, and which could have devastating impact on bacterial biodiversity.
