Proximate composition, percentage daily value and anti- nutritional levels of raw and boiled leaves of Heinsia crinata (HC) and Vernonia amygdalina (VA) were investigated using standard methods. There was no significant difference (p > 0.05) between the crude protein values of VA (3.80%) and HC (3.76%). Boiling decreased the protein content of the vegetables (HC: 3.65±0.02%; VA: 3.70±0.02%). The ash content of HC (2.36±0.02%) was significantly higher (p < 0.05) than the ash content of VA (1.64±0.02%) but boiling decreased their ash content.

The aim of this study was to examine the epidemiology of intestinal parasites and determine the risk factors linked to infection among primary school children in the Amai community. The research was conducted with 778 students from May to November 2017. Stool samples were obtained and tested for intestinal parasites using the direct smear (wet mount) technique, demographic and epidemiological information were obtained using well-structured questionnaires and the statistical analysis was carried out using Microsoft Excel and GraphPad Prism.

Microplastic pollution poses a growing threat to aquatic ecosystems and biodiversity due to its persistence and potential harm to human health. This study examines the occurrence, distribution, and ecological impact of microplastics in surface water from River Nun, Bayelsa Central, Nigeria. Sampling was conducted at six locations over six months (January–March and July–September 2024). Samples were processed using NOAA techniques, including filtration, density separation, and microscopy, while FTIR and GC-MS were used for polymer and additive analysis.

The accumulation of metals in different environmental compartments poses a risk to both the environment, human and biota health. The combination of both Phyto and nano remediation techniques have been gaining more attention in this regard. This technique leverage on the unique and specific absorption qualities of plant roots, and employs these inherent processes with the bioaccumulation, translocation, and pollutant degrading capacities of the whole plant as well as cost effectiveness, and potential to treat a broad range of contaminants.

Industrial processes, including scrap yards, can contaminate surface waters with heavy metals, posing a risk to aquatic habitat and human health. Thus, the concentrations, ecological and health risks of heavy metals in surface water and sediment of the Ogun River in Lagos was investigated. Surface water and sediments collected from the Ogun River were analyzed for some physicochemical parameters and heavy metals using standard procedures.

The aim of this study is to assess heavy metals levels, pollution indices and ecological risks of floodplain sediments in urban areas in Delta State, Nigeria. The levels of nine heavy metals (Cd, Pb, Cr, Ni, Cu, Co, Mn, Zn and Fe) were measured in floodplain sediments of urban areas in Delta State, Nigeria. Sediment samples from the nine urban areas were collected for three months (July-September) covering the wet season. The sediment samples were digested with aqua regia, and the heavy metal levels in the digests were quantified by means of atomic absorption spectrometry.

This study aimed to evaluate the risks associated with water quality in public institutions in Warri, Delta State. Water samples were collected from five public institutions namely, School, Hospital, Mall, Church and Hotel. Physico-chemical and microbial analyses were conducted using standard methods. The water quality index (WQI) and risk assessment matrix (RAM) were applied the quality and potential risks. Results revealed slightly acidic pH levels (5.1-6.63) in water samples. Dissolved oxygen levels (3.8-4.2 mg/L) were below WHO recommendations.

The study evaluates the physical, chemical and heavy metal properties of the Agbarho River, Delta State, Nigeria using standard methods for analysis with a view of ascertaining the water quality and establishing the correlation with national and international standards. The analyses revealed the water to be slightly acidic (pH - 5.60±0.31).

This study evaluated the enteric bacterial contamination of cabbage, cucumber and carrots sold within Anyigba, Kogi State. These vegetables which are usually eaten raw in coleslaw and salads were analysed for the presence and level of enteric bacteria using standard microbiological procedures. Results revealed bacterial contamination of the vegetables with enteric bacteria from all the sales points. Mean bacterial counts recorded for theses vegetables from Good shepherd Hospital sale point, were 8.9×106, 1.03×107, and 4.85×106 cfu/g for cabbage, carrot and cucumber respectively.

This study was conducted to evaluate the ameliorative effect of selected fungi (Aspergillus sp, and Penicillium chrysogenum) on arsenic-treated (As3+) soils used for the cultivation of Abelmoschus esculentus. Stress alleviation property of the fungi spp was done in soils contaminated with different concentrations of As3+ solution, and inoculation of fungi was done two weeks after planting.
