The potentials of Parkia biglobosa (a leguminous plant species) to decontaminated crude oil-polluted soil in terrestrial ecosystem was evaluated in this study using appropriate standard techniques to estimate seedling germination, height, collar diameter, number of leaves and physicochemical characteristics (organic matter, pH, calcium, magnesium and sodium, nitrogen, phosphorous and potassium) of soil used, were determined using standard protocols. Results indicated that varying concentration of crude oil influenced the variables measured. For 0 ml, 25 ml, 50 ml, 75 ml and 100 ml crude oil treatments, Parkia biglobosa had 18%, 18%, 16%, 13% and 11% germination rate correspondingly; mean height of 38.70cm, 26.80cm, 21.20cm, 18.50cm and 6.80cm respectively, mean collar diameter of 0.32mm, 0.30mm, 0.26mm, 0.24mm and 0.22mm respectively; 2, 0, 0, 0 and 0 nodules count respectively, and 8.00, 6.00, 5.00, 5.00 and 2.00 leaf count respectively. All physicochemical parameters measured decreased in the soil in inverse proportion to crude oil concentration. So also, seedling germination, height, collar diameter, number of leaves and nodulation decreased in inverse proportion to crude oil concentration. Parkia biglobosa grew tolerably in both high and low concentrations of crude oil, which is an indication of its able to withstand crude oil toxicity. Parkia biglobosa as a nitrogen fixing plant would be a good candidate for the terrestrial restoration of crude oil contaminated regions in Nigerian.

Flour forms the skeleton that supports the other ingredients in a baked products such as bread, cakes, and pastries. Both the physical and chemical characteristics of flours affect their quality and the subsequent products from them. Hence, this paper evaluates the proximate composition, farinographical and extensographical properties and sensory evaluation of sausage rolls made from wheat-breadfruit flour composite using standard methods. Breadfruit substitutions decreased the protein contents while ash, crude fibre and moisture contents increased significantly (p ≤ 0.05) in the blends. Likewise, the pasting properties and sensory evaluation showed that BF substitution up to 25 % resulted in the dough and a sausage rolls that were similar to 100 % wheat dough and sausages. Further optimisation of the baking parameters showed that 25 % bf substituted flour could be baked at (160 -190 oC) for 20 – 29 min to produce a highly acceptable sausage roll. These results of the study showed the possibility of replacing wheat flour with breadfruit flour in the production of good quality sausage rolls.

Cultivation of Pleurotus species, an Oyster mushroom is now becoming well known due to its taste, medicinal and nutritional values. It is capable of degrading agricultural wastes efficiently and even grows at different temperature ranges. Relatively, Pleurotus species has shorter life span and the fruiting bodies are rarely attacked by pests and diseases unlike the other edible mushrooms. Therefore, the aim of this research is to access the influence of mineral constituents of five local wood wastes (Anogeissus leiocarpa, Pouteria altissima, Vitellaria paradoxa, Cordia milleni and Triplochiton scleroxylon) in Ibadan metropolis on the growth, fruiting body yield and proximate analysis of cultivated oyster mushroom (P. sajor-caju). Data of Carbon/Nitrogen ratio (11.10 – 11.60) found reveal composition of Magnesium (0.035 mg), Potassium (0.053 mEq/l), Manganese (0.0013 mg), Copper (0.00050 g/m3), Iron (0.00275 mol/L), Phosphorus (0.027 mmol/L), Organic carbon (32.10 mg/L C), Organic matter (55.3 t/ha) and total nitrogen (2.77 mg/L) contributed greatly to the high crude protein, fats and ash contents of mushroom cultivated on T. Scleroxylon. However, insignificant contents of sodium (0.2 mg), Calcium (0.2 mmol/L) and Magnesium (0.013 mg) in Pouteria altissima led to the general inadequate performance of (P. sajor-caju) in yields. The fresh mean weight of (P. sajor-caju) was from 8.00 g – 27.53 g. The heaviest weight was obtained from T. scleroxylon followed by V. paradoxa, C. milleni, while Anogeissus leiocarpa gave the lightest weight. Hence, T. scleroxylon will be suggested for cultivating P. sajor-caju because of its positive impact on the yield, crude fibre, and protein content of the experimented mushroom.

Heavy metal pollution in aquatic ecosystems can be assessed with suitable biomarkers in fish. This study was carried out to determine the concentration of heavy metals and gene expression of African Arowana Fish (Heterotis niloticus) obtained from Igbalegbe River, Ughelli, Delta State, Nigeria using Atomic Absorption Spectrophotometer (Varian 220 Fast sequential) for the metals and Polymerase chain reaction (PCR) for the gene expression study. Results of the study showed that fishes in the downstream sectionof the river and the effluent discharge point recorded higher metal pollution Index (MPI) compared to the upstream station. The concentration of heavy metals in the fish tissue were generally within the limits of Food and Agricultural Organisation (FAO)/World health Organisation (WHO) except for that of Cadmium and Lead in the discharge station. The selected genes investigated were biomarkers for general stress (HSP70), xenobiotic metabolism (CYPA1), antioxidative defence (SOD), Insulin growth factor-1 (IGF-1) and hypoxia inducible factor (HIF) respectively. The expression of the genes revealed significant variations (P<0.05) in the fishes obtained from the different stations of the river. Some of the genes were down-regulated and suppressed while others were upregulated to enable the fish cope with stress while adapting to environmental pollution. Changes in biomarkers can therefore be considered as early signals of stress in the selected fish species.

The aim of this paper was to evaluate the hydrogeochemistry of groundwater suitability for drinking and irrigation purposes in Okerenkoko Gbaramatu Kingdom, South-South Region, Nigeria using standard methods. The results obtained in the study indicates that over 70% of the groundwater under investigation fell in the category of C3S1 and C4S1 in the USSL salinity diagram implying high to very high salinity. The concentration of Lead (Pb) in all the samples collected exceeded the recommended value of 0.01 mg/L set by the World Health Organization and the Standard Organization of Nigeria respectively. Groundwater from the study area can only serve as irrigation purpose for salt tolerant crops like the sweet potato, grain-sorghum, sugar beet, cotton and carrot. The production of these crops on the vast arable fallow land will contribute significantly to food security and economic advancement of the study area and the global community at large. Conversely, the groundwater cannot be consumed unless treatment is administered.

Humanity's pollutive activities pose significant threats to biodiversity, agricultural productivity, and human health. Effective communication about these issues is crucial for fostering awareness and understanding. To achieve a more impactful dialogue, it is essential to facilitate collaboration across disciplines through an interdisciplinary system approach. This paper specifically aims to examine the role of storytelling, humor, and celebrities' influence in reinforcing pro-environmental behaviors. The focus is on reducing pollution and its impact through experiential, emotional, and aesthetic learning. To ensure the validity of the review, articles were systematically collected from accredited journal sites indexed by Scopus, Web of Science, and other reputable sources. The analysis indicates that anthropogenic pollutants, ingested through food, soil, air, or water, can have disastrous effects on human and environmental health. The study emphasizes the potential of storytelling, humor, and celebrities' influence to significantly mitigate these impacts. The integration of humor, storytelling, and the influence of celebrities in the media, as powerful communication tools, can contribute to a drastic reduction in pollution and its associated effects. These approaches serve as universal languages that resonate with diverse audiences. The study advocates for strong advocacy and effective communication strategies employing humor, storytelling, and celebrity influence. Celebrity influencers, with their substantial social influence, can act as science communicators, translating complex pollution statistics to inform the public about their contribution to pollution and motivating behavior change for environmental health improvement.

Environmental pollution is a growing concern, with its detrimental effects on ecosystems, biodiversity, and human health. Spent lubricating oil (SLO) represents a pervasive environmental pollutant, often finding its way into soil and posing a significant threat to plant life. This study was to investigate effect of the fractions of SLO (water-soluble, WSF; water-insoluble, WISF; and crude whole SLO, cWSLO) and distilled water (DW) respectively. The WSF showed significant (P<0.05) decrease in both species of seedlings (Sorghum 15.34 mg GAE/g ± 2.01 and Soya-bean 16.87 mg GAE/g ± 0.86) from results of TAP when compared to that of DW while the cWSLO was most significantly (P<0.05) decreased. The TPC also revealed significant (P<0.05) decrease from the different fractions when compared to the control (DW) as well as that of the TFC values from the results. The disparities in TPC emphasize the selective influence of different SLO components on the production of phenolic compounds, which could be crucial for plant defense mechanisms against oxidative stress. Thus, the results of the study showed that although the different parameters indicated that SLO can affect the oxidative state of brown sorghum seeds but it can be seen that it may be possible for the plant to utilize some of the water soluble contents of the SLO to aid germination.

This work measured the activity concentration of natural radionuclides 238U, 232Th and 40K in soil and rock samples collected in Ugwuele mining site and it surrounding communities in Uturu, Abia state, Nigeria. Fifteen different samples collected were analyzed. A NaI (Tl) spectrometry detector system was adopted for this research. The results obtained were used to estimate the radiological implication of the quarry mining in the study area. The average gamma activity obtained for 238U, 232Th and 40K in soil were 53.39 ± 3.08, 76.79 ± 9.66 and 1061.02 ± 15.72 Bq/kg respectively and 55.09 ± 5.71, 90.96 ± 16.10 and 1281.78 ± 6.38 Bq/kg respectively for rock samples. The calculated radiological hazard indices from Absorbed dose rate, Annual effective dose, Radium equivalent, internal hazard index and External hazard index gave 120.25 nGy/h, 0.147 msv/yr, 247.5 Bq/kg, 0.833 and 0.687 respectively. The average dose rate was higher than the recommended limit. Therefore, soil and rock materials found in Ugwuele could increase the radiological hazards on miners and residents of the area due to long time cumulative exposure.

The brewing industry consumes a large amount of water needed for brewing, rinsing, and cooling purposes, and therefore produces huge amount of effluents. Therefore, the objective of this paper was to evaluate the use of Moringa oleiferra (MO) powder and synthesized 1.0 and 2.0 g TiO2NPs as green synthesized nano-particles for the remediation of brewery wastewater using standard methods. The raw wastewater sample characterization for pH, BOD, COD, Lead and coliform count were: 7.26, 935, 1045, 0.083 mg/L and 136 cfu/100 mL respectively. Results of the UV – Visible spectrophotometer showed the maximum wavelength of 275, 275, 278 and 282.50 nm for 5:20, 10:20, 15:20, 20:20 of MO and TiO2 ratio respectively, while the FTIR results show the presence of oxygen surface complex groups such as hydroxyl and carbonyl. The SEM reveals a porous surface area accompanied by several wide opening pores of different sizes and shapes, while EDX shows the concentration of titanium, Sulphur and silicon in percent weight; 85.79, 2.96 and 1.46 % respectively. Results of the wastewater treated with 50 g defatted M. oleiferra revealed the removal efficiency of 47, 93.2, 56.2, 18, 31.3, 97, 76.1, 81 and 71% for Turbidity, COD, EC, Nitrate, Nitrite, BOD, TS, TDS and TSS respectively. Results of wastewater treated with 1.0 g of TiO2 NPs showed the removal efficiency of 97.8, 94.64, 53.5, 34.2 and 35.1% for COD, BOD, EC, Nitrate and Nitrite respectively. That of 2.0 g of TiO2 NPs showed the removal efficiency of 67, 58, and 87% for Cu, Pb, and Ag respectively. Conclusively, M. oleiferra and varying proportions of green synthesized TiO2 NPs were effective in the remediation of the wastewater from brewery industry as it improves its physicochemical properties, but not so much for the heavy metal concentration.

SAAF Fungicide is a systemic and contact fungicide that is used to prevent leaf spot, blast disease, rust disease, and other types of fungi pests in all kinds of crops, especially on vegetable plant. Hence, the objective of this paper as to compare the effects of Potassium Iodate and SAAF-fungicide on the control of Fusarium Wilt (Fusarium oxysporum) and the Yield of Pepper (Capsicum spp L.) using appropriate standard methods. Agronomic data such as number of leaves, plant height and flowers was collected. Disease incidence and severity as well as yield were measured and analyzed using Analysis of Variance (ANOVA). Among all the treatment, Gulpinar F1 with KIO3 has the highest height and number of leaves across the experiment while negative control has the least height and number of leaves. De cayenne with SAAF has the highest yield of pepper harvested followed by Gulpinar F1 with KIO3, the negative control has the highest disease infection and severity, there are very mild infection on the treated plots. The two treatments have positive effect on the growth, disease control and yield of pepper. The highest pepper yield was achieved from SAAF treated sample.
