“…In this work, we analyzed Arabian fossil oil for the content of metal impurities and obtained 14, 9, 6, 3.5, 5, 10, 11 and 2 ppm for Ca, Fe, Mg, Cu, Zn, Na, Ni and Mo, respectively [61], which is less than our data. When compared with fossil oil or soil in oil production areas, it can be noticed that there is a greater concentration of heavy metals in the bio-oil obtained in this work, which leads to the need for additional stages of bio-oil purification [62][63][64]. The results of the GC-MS of bio-oil are presented in Table 5.…”

In this work, the path from the cultivation of Arthrospira platensis at an increased concentration of CO2 to the production of bio-oil by hydrothermal liquefaction (HTL) of the grown biomass is realized. The cultivation was carried out in a 90 L photobioreactor at an initial CO2 concentration of 8 vol.% for 15 days. During the cultivation stage, the optical density for microalgae suspension, pH and chemical composition of nutrient medium were monitored. The grown biomass was separated from the nutrient medium with a 100 µm mesh and then subjected to HTL at 330 °C for 1 h. The biomass growth rate was 82 ± 4.1 mg × L−1day−1 and the pH was in the range from 9.08 ± 0.22 to 8.9 ± 0.24. Biochemical and CHNS analyses were applied for the obtained biomass. The contents of carbohydrates, proteins and lipids in the grown biomass were 38.7 ± 0.4 wt.%, 37.4 ± 0.5 wt.% and 3.8 ± 0.4 wt.%, respectively. Bio-oil yield after the HTL procedure was 13.8 wt.%. The bio-oil composition and properties were determined by GH-MS, TLC-PID and ICP-MS techniques. ICP-MS revealed the contents of 51 metals in bio-oil.

The physicochemical properties of groundwater, geochemical characteristics and subsurface formation of the Oke-Tage waste dumpsite soil material were assessed to determine the impact of the leachate generated from the waste dumpsite on the quality of the groundwater within the study area. Water samples collected from hand-dug wells were analyzed to determine groundwater quality, while soil samples were examined for their geochemical characteristics. Ten Vertical Electrical Sounding (VES) surveys were carried out with an electrode spacing (AB/2) increasing from 1 to 200 m. Also, four 2D electrical resistivity profilings were done using the dipole–dipole configuration. The hydro-chemical analysis showed an elevated Cadmium (Cd) and Lead (Pb) concentration above the maximum permissible limits. The physicochemical results indicated that the Electrical Conductivity (EC) ranged from 1900 to 3670 µS/m, while Total Dissolved Solid (TDS) ranged from 585 to 620 mg/L. The health risk assessment showed no significant health risks associated with exposure to the metals due to HI values less than 1. Based on the VES result, four geoelectric layers comprising topsoil, weathered layer, fractured basement, and fresh basement were identified. The 2D resistivity structures revealed that the topsoil and weathered layers practically merged and are characterized by relatively low resistivity (< 30 Ωm) beneath the dump site. The study concluded that the groundwater and soil in the vicinity of the investigated Oke-Tage waste dumpsite had been negatively impacted to levels that called for caution especially using the water for regular potability purposes.

“…The discharge of PRE into the environment will impact the ecosystems and the biological systems of living organisms. As demonstrated by Adebiyi, the soils surrounding a petroleum refinery products station were revealed to contain heavy metals such as (Fe, Cu, Cd, As, Pb, Ni, Zn, and Cr) at increased levels, these metals have the potential to contaminate the surrounding ecosystem ( Adebiyi et al, 2020 ). Also, as seen on surface soil near an oil refinery, high levels of Yb, Eu, Mo, Hf, Cd, and Tb presence can cause severe pollution ( Alshahri & El-Taher, 2018 ).…”
