“…PHCs are common environmental contaminants found in soils, waters and sediments (Sammarco et al, 2013;Li et al, 2014). PHCs consist of a complex mixture of aliphatic and aromatic compounds with different concentrations that are considered toxic for human and livestock (Ritchie et al, 2001;Yang et al, 2017). Especially, the polycyclic aromatic hydrocarbon (PAH) fraction contains toxic compounds that can be either adsorbed and further accumulated in the soil, or leach to groundwater and, subsequently, causing significant food chain contamination (Chen et al, 2013).…”

Rapid analysis of oil-contaminated soils is important to facilitate risk assessment and remediation decision-making process. This study reports on the potential of a handheld midinfrared (MIR) spectrometer for the prediction of total petroleum hydrocarbons (TPH), including aliphatic (alkanes) and polycyclic aromatic hydrocarbons (PAH) in limited number of fresh soil samples. Partial least squares regression (PLSR) and random forest (RF) modelling techniques were compared for the prediction of alkanes, PAH, and TPH concentrations in soil samples (n = 85) collected from three contaminated sites located in the Niger Delta, Southern Nigeria. Results revealed that prediction of RF models outperformed the PLSR with coefficient of determination (R 2) values of 0.80, 0.79 and 0.72, residual prediction deviation (RPD) values of 2.35, 1.96, and 2.72, and root mean square error of prediction (RMSEP) values of 63.80, 83.0 and 65.88 mg kg-1 for TPH, alkanes, and PAH, respectively. Considering the limited dataset used in the independent validation (18 samples), accurate predictions were achieved with RF for PAH and TPH, while the prediction for alkanes was less accurate. Therefore, results suggest that RF

“…Breathing the compound at concentrations greater than 100 parts per million (100 ppm) for more than several hours can cause fatigue, headache, nausea, and drowsiness. When exposure is stopped, the symptoms will go away [26]. However, if someone is exposed for a long time, permanent damage to the central nervous system can occur.…”

The liquid-liquid extraction of Petroleum contaminated surface water samples were conducted in accordance with standard procedure of US EPA. Identification and quantification of TPHs was performed by Gas chromatograph with Mass spectrometric detection (GC/MSD) in accordance with standard analytical method of US EPA 8270;625. The TPHs raw sample showed an elevated value of 104762.42 mg/L above the DPR/EGASPIN maximum contamination limit (MCL). At week 5, TPHs phytoremediations in the monoculture reactors removal efficiency was (31.28 mg/L) 99.97% and mixedculture indicated (19.72 mg/L) 99.98%; their concentrations were above DPR/EGASPIN MCL while polyculture indicated (8.91 mg/L) 99.99% value was below DPR/EGASPIN MCL. The combination of phytoremediation and vermiremediation techniques in polyculture reactors showed better and spectacular results as the biotas demonstrated good potentiality of hyperbioaccumulation to serve as hydrocarbon sinks from the ecotoxics of TPHs.

“…This innate organism-protecting strategy to protect the cells from the damaging effects of free radicals can only be partly achieved through superoxide dismutase (SOD), glutathione reductase (GR), and the reductase (GSH-RADC) (He et al, 2017). Nowadays, the use of herbal medicines has become increasingly widespread as a treatment for therapeutic issues (Yang et al, 2017). Medicinal plants are of interest because of their pharmacological activities, their economic feasibility, and low toxicity, all of which has resulted in them being the subject of extensive research (Ayoub & Mehta, 2018).…”

Cordia myxa L. is one of the medical plants that plays an important role in the treatment of many diseases. There are many studies explained that C. myxa can show anti-inflammatory, anti-diabetic, antiparasitic, antimicrobial and immunomodulatory properties. This review was focused on the active compounds and medical effects of C. myxa. The fatty acids contents are particularly high (9.9%). Sodium and potassium constitute the largest mineral proportion (13 ppm and 29 ppm respectively) of the fruit. However, the toxic heavy metals such as lead, cadmium, chromium and copper have not been found in the fruit. This gives an additional significant benefit of the medical uses of the plant. The content of alkaloids, saponin, polyphenols, and comarine were recorded and was relatively high compared to steroids, resins, glycosides, tannins, and gum that found to be in less amounts. When the mucilage was extracted, the alkaloids constitute more than 35%. By using the Folin‐Ciocalteu, C. myxa extracts have a high Phenolic content. The antibacterial activity against gram-negative bacteria were included in the fruit mucilage extract while the alcoholic extracts have no effect on all bacterial isolates. In addition, the mucilage extract showed anti-parasitic activity when it was tested against Leishmania infantum promastigotes. However, the highest concentration of extract significantly reduced the amounts of lymphocytes. Moreover, ethanolic extracts of C. myxa fruits give rise to leucocyte and lymphocyte count. Future research needs to be done on this kind of herbs which could show high medicinal activity.
