Abstract

A leading cause of land use and land cover changes is human population growth as well as urbanization. This study aimed at identifying the changes in land use and land cover around a bridged point of Ikpoba River, Benin City, Nigeria, coupled with  the examination of selected physicochemical attributes of surface water samples collected from the river around the bridged section. Land use and land cover change analysis was done using images from Landsat 5 and 7 for the years 1991, 2002, 2012 and 2022 using ENVI 5.3 software. Surface water samples were collected from 3  sampling points  in a three month period; May to July, 2023. The monthly grouped mean data for each sampling point were subjected to one way analysis of variance (ANOVA) and  mean separation was also carried out using  a post hoc test; Duncan’s multiple range test at 95% level of confidence.Land use maps revealed that there was a decrease in the forested areas, grasslands and water bodies and an consequent increase in the barren land as well as  built up areas between the years; 1991 and 2022. There were variations in the mean pH and turbidity values. The range of these parameters were; 5.91± 0.05  to 6.76 ±0.10 and 12.50 ±0.50 to 131.50 ± 3.50 mg/l. The variation in the  mean pH values was insignificant (p>0.05) whilst the difference in the mean turbidity readings was significant (p<0.05). It is recommended that protective measures be implemented to protect the remaining forested areas while encouraging reforestation of barren lands.

Abstract

Edible film is a thin layer for primary packaging of food consisting of consumable components. In general, the purpose of this research is to examine the mechanical and physical properties of edible film in the influence of the addition of PVA and sorbitol as plasticizers and get the best edible film characteristics to be used as food packaging materials. The weight variations of porang flour used were 5 grams, 6 grams, 7 grams, 8 grams, and 9 grams. With sorbitol volume of 1 ml, 2 ml, and 3 ml, 4 ml, and 5 ml, and PVA mass of 3%, 4%, 5%, 6%, and 7% (b/v). The drying operation temperature was 40oC, 50oC, 60oC, 70oC, 80oC and the drying time was 12 hours and 24 hours. Then the thickness test, mechanical test, water resistance and solubility test, water vapor transmission test, and SEM (Scanning Electron Microscope) analysis were analysed. The best results are with variations of porang flour 6 grams, sorbitol 5 ml, PVA 5%, drying temperature 40℃, and drying time for 12 hours. The more sorbitol is added, the thickness, water resistance, water solubility, and elongation of the edible film will increase. The addition of konjac flour increases the thickness, water resistance, water solubility, tensile strength, and elongation of the edible film. However, it is inversely proportional to the water vapor transmission of edible film which has decreased.

Abstract

Glutathione-S-transferases (GSTs) are phase-II metabolizing enzymes which detoxify various compounds through their conjugation reaction. This study characterized and investigated the kinetic properties of liver glutathione-S-transferase in rats exposed to glyphosate. Rats of average weight 200 g were randomly divided into groups (n=4); A, B, C and D. Group A served as control and received distilled water alone while groups B, C and D were exposed to 200, 300 and 400 mg/kg body weight of glyphosate respectively. Three GST model substrates [1, 2-dichloro-4-nitrobenzene (DCNB), paranitrobenzylchloride (pNBCl), and 1-chloro-2, 4-dinitrobenzene (CDNB)] were used to determine the substrate utilization pattern of the GST isozymes in the liver crude homogenate. The liver homogenate was purified by combination of 80 % ammonium sulfate precipitation, gel filtration chromatography on Sephacryl S-200 column and ion exchange chromatography on CM-Sepharose column. Spectrophotometric methods were used to determine the activity of the GSTs and protein concentration. GST isozymes in the liver homogenate were unable to conjugate pNBCl to GSH, DCNB showed slight conjugation while CDNB shows a 2-fold conjugation. The optimum temperature for the induced isozymes of GST A and GST B were 400C and 500C respectively while the optimum pH were 8.0 and 8.5 respectively. In this study, pNBCl proved unsuitable due to its inability to conjugate GSH. Future study may provide additional information about the class of GST isozyme induced.

Abstract

Mangrove water is habitat for aquatic organisms and is important for water supply, transportation, agricultural and industrial activities. This study aims at evaluating the physico-chemical properties of mangrove water from the mangrove forest of Gbaramatu Kingdom Warri South West LGA, Delta State, Nigeria. The physical and chemical properties of the mangrove water sample were determined using standard methods of AOAC, APHA, and ASTM. Enumeration of total heterotrophic bacteria in the mangrove water sample was evaluated by colony‐forming units (CFU) method. Bacterial isolates were identified and characterized by colony and morphology characteristics, microscopic examinations and biochemical tests. The mangrove water demonstrated 33 °C, 8.3, 35.63 NTU, 23915.53 µS/cm, 2213.13 mg/L, 10411.99 mg/L, 38.40 mg/L, 18545.11 mg/L, 5.40 mg/L, 18.51 mg/L, and 52.00 mg/L mean value of temperature, pH, turbidity, conductivity, salinity, TH, TSS, TDS, DO, BOD, and COD, respectively. The concentration of total alkalinity, bicarbonate, chloride, sulphates, phosphate, and nitrate in the mangrove water were 142.15 mg/L, 110.05 mg/L, 349.97 mg/L, 78.05 mg/L, 1.50 mg/L, and 0.07 mg/L, respectively. The mangrove water sample contains high significant number of heterotrophic bacteria. The values of physical and chemical parameters in the mangrove water sample are above the recommended values by WHO for domestic use.

Abstract

This study explores the potential of green mussel shells as a filtration medium for treating laundry wastewater. The research evaluated the effects of ozonation as a pre-treatment step and compared two filtration reactors, reactor one (R1) without green mussel shells and reactor two (R2) using green mussel shells. In this filtration system, hydrostatic force is used due to its reliability in determining the pressure difference between the upstream and downstream sides of the reactors. Treated wastewater samples were collected every 5 minutes to be analyzed. Several important water quality parameters are monitored, including pH, chemical oxygen demand (COD), and dissolved oxygen (DO). The odor and color of the laundry wastewater were also observed. Results showed the effectiveness of green mussel shells in improving wastewater quality, particularly in neutralizing pH, reducing COD, and increasing DO. The results of linear regression calculations showed that in R2, the pH decreased by around 26%, the COD concentration decreased by 76%, and the greater increase in DO was 118% from the concentration without treatment. This research showed that green mussel shells in R2 have the potential to be used as a filtration element to treat laundry wastewater as a sustainable solution, addressing both environmental pollution and water quality challenges.

Abstract

Renewable energy is a primary energy source that naturally replenishes itself over time. It is derived from various large-scale sources, including ocean tides, sunlight, rainfall, wind, biomass, and geothermal heat generated deep within the Earth. In 2008, about 19% of global energy consumption came from renewable sources, with approximately 13% from biomass and 3.2% from hydroelectric power. A microbial fuel cell (MFC) is a reliable technology that generates electricity while removing contaminants from wastewater. The bacteria in the MFC's anode facilitate the breakdown of the substrate, producing electrons and protons through anaerobic respiration of the substrate. This research is based on finding a more effective means and technique for high production of electricity using MFCs as well as to ascertain the efficiency of MFCs in the treatment of Whey as a wastewater.  Methods such the APHA, photometric method, turbidometry and ascorbic acid methods were used to determine components like BOD, COD, TSS, phosphorus and sulphate contents respectively. Cheese whey shows promise for electricity generation in microbial fuel cells (MFCs) compared to other biomass sources. The highest voltage and current achieved with cheese whey were 56.8 mV and 5.68 mA, while the maximum current and power densities for MFC I were 0.339 mA/cm² and 19.2 mW/cm². In MFC II, peak voltage and current reached 73.7 mV and 7.37 mA, with a maximum current density of 0.44 mA/cm² and power density of 32.4 mW/m². This experiment showed efficient COD removal rates of 83.97% and 92.85% for MFC I and MFC II, respectively, and BOD₅ values of 61.95 and 73.95, indicating good biodegradability of the substrate, with BOD/COD ratios of 0.65 and 0.60.
