Background and Objective: Soil plays a major role in food safety and security. A major problem in most developing nations is a lack of food security and safety. The soil environment is a reservoir of nutrients as well as pollutants. This study eval_uated the health risk and heavy metals speciation of arable farmlands in Ardo-Kola, Zing and Yorro, Local Government Areas of Taraba State, Nigeria. Methodology: Three different soil samples from three Local Government Areas of Taraba State (Ardo-Kola, Zing and Yorro) were collected using sterile glass sample collection bottles measured at 5 cm depth. The collected soil samples were freed from unwanted materials by hand picking and air-dried for 5 days to remove excess moisture. The dried soil samples were crushed in with mortar and a pestle, the crushed soil sample was sieved through a 2 mm sieve made of stainless steel the sieved soil sample was further pulverized to a fine powder and passed through a 0.5-mm sieve. Heavy metals (Pb, Cd, Cr, Hg and As) concentrations were assayed using Atomic Absorption Spectrophotometry (AAS). Results: The results showed that Chromium had a high concentration with values ranging from 1.83 mg/kg to 2.62 mg/kg. While Lead and Mercury had the lowest concentration of less than 0.03 mg/kg across the studied areas. For ecological risk assessment parameters; target cancer risk, hazard index (HI) estimated daily intake (EDI) were all determined to assess the non-carcinogenic health risk. Ardo-Kola recorded the highest levels of HM, followed by Yorro, whereas Zing had the lowest concentration. Consumption of crops harvested from the sampled location may pose a serious health challenge; bio-accumulation of toxicants in the soil across the studied areas may pose a health risk due to high concentration of heavy metals which are known to generate free radicals that may lead to oxidative stress and other cellular damages in humans. Conclusion: Although most of the studied heavy metals were significantly present in all the analyzed soil except lead and mercury, their concentration in various soil samples across the studied areas exceeded the permissible levels as recommended by WHO except for Lead and mercury.

Phenol is a harmful compound found in soil, and its removal is crucial for human health. Phenol or hydroxybenzene, is both a synthetically and naturally produced aromatic compound. Microorganisms capable of degrading phenol are common and include both aerobes and anaerobes. In this study, researchers collected soil samples from INEX refuse dumping site along Bajoga road of kwami, Gombe state, and determined the abundance of heterotrophic and degradation bacteria using serial dilution and most probable number (MPN) methods. This experimental research study was carried out in order to isolate and identify phenol-degrading bacteria in polluted soil, the effect of concentration and pH was analysed during the procedure. Bacteria was isolated from contaminated soil and sub-cultured in a Mineral-salt media which was prepared with phenol added as the only carbon source needed for the bacterial growth, The bacterial isolate was identified as Escherichia coli a gram-negative bacteria. The favourable concentration and pH required for the growth of the bacteria was determined as 200mg/L and pH 7 respectively. These findings have significance in bioremediation for employing suitable bacteria in suitable condition for solving environmental pollution crises.

Broad biological activities of “plasma-activated water” (PAW) have drawn great attentions recently. Treatment of water using gas discharge plasma led to acidic solutions with excellent and broad antibacterial activity. Because PAW caused severe membrane damages in bacteria and diffused freely in extracellular matrix, PAW also demonstrated good anti-biofilm activity. However, further studies revealed that trace amounts of metal ions (mainly copper) in PAW brought by plasma treatment played key roles in bacteria inactivation. The contribution of metal ions to the antibacterial activity varied among PAWs from different working gases. However, solution acidification caused by reactive species in plasma was essential. The experimental results demonstrated that potential artifacts in reported biological activities of PAWs should be considered. Therefore, Copper has important redox activity and can participate in various biochemical reactions by accepting and donating electrons. As a trace element, thus, Anticancer effect of Copper Activated Plasma Water on MCF7 Breast Cancer Cells. Materials and method, used are a non-thermal micro-hollow cathode discharge (MHCD) was used to generate plasma-activated waters (CU-PAWs), The MCF-7 human breast adenocarcinoma cell line (IBRC C10082), and 3-(4,5 dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) was acquired. Cell Viability Measurements; After 48 h of incubation 0.5 mg/ml MTT (20 μl) was added to the control and experimental cells and the cells were incubated for 3 h in a CO2 incubator at 37 °C, Measurement of Reactive Oxygen Species (ROS) and Flow Cytometry was conducted. Results: The 3- and 4-min CU-PAW reduced MCF-7 cells viability to approximately 62% and 56% of control (p< 0.01), respectively. However, in the cases of 1- and 2-min CU-PAW cell proliferation did not diminish significantly as compared with the control group (p> 0.05). This observation is consistent with earlier studies, which illustrated that plasma irradiation reduced cell viability in a time-dependent manner. Thus, in this research, DOX (0.45 µM) combined with 3- or 4-min CU-PAW killed MCF-7 cell efficiently (44% and 39% cell viability, respectively; p< 0.01) than DOX (54% cell viability) or 3- or 4-min CU-PAW alone (63% and 56% cell viability, respectively). These was in line with a that PAW plus cisplatin at low doses reduced viability of human endometrial carcinoma more effectively than cisplatin or PAW alone. Conclusion: Although further investigations are crucial, CU-PAW combined with DOX could be a promising cancer treatment strategy, contributing to a more positive therapeutic agent.
