Advected cyanobacteria, algal blooms and cyanotoxins have been increasingly detected in freshwater ecosystems. This review gives an insight into the present state of knowledge on taxonomy, dynamics, toxic effects, human ecological health implications East African Community lakes. The major toxigenic microalgae lakes include Microcystis, Arthrospira, Dolichospermum, Planktolyngbya Anabaenopsis species. Anatoxin-a, homoanatoxin-a, microcystins (MCs), cylindrospermopsin nodularin quantified...
Microplastics (MPs) have been extensively studied in the marine environment, but reliable data on their sources and pathways freshwater ecosystems, which are main of such pollutants, still limited. In this study, we investigated spatiotemporal variations, characteristics, MPs Nakivubo catchment, drains waste stormwater from Kampala city (Uganda) empties it into Lake Victoria through channel. Surface water samples (n = 117) were collected thirteen sites catchment (S1 to S13) during dry wet...
In this study, activated carbons prepared from agrowastes by chemical activation were used to remove acetic acid an aqueous solution through a batch process. The adsorbents characterized SEM, XRD, FT-IR, and point of zero charge (pHpzc). effects adsorbent dosage, initial concentration, contact time considered. Equilibrium data was tested using Langmuir, Freundlich, Temkin, Frenkel–Halsey–Hill models. degree adsorption increased for both as time, dosage concentration increased. described well...
Abstract Grand Canonical Monte Carlo (GCMC) simulations have been used to evaluate the hydrogen storage performance on 233 zeolites. LTA had highest capacity with a of 4.8%wt. The second ranked zeolite is JBW uptake 3.25% wt, while RTH was third 2.89% wt. A machine learning algorithm rank importance various structural features such as mass (M), density (D), helium void fraction (HVF), accessible pore volume (APV), gravimetric surface area (GSA), and largest overall cavity diameter (Di) how...
Aflatoxin B1 is a toxin produced as secondary fungal metabolites by the fungus Aspergillus, particularly A. flavus. The has significantly contaminated food supply chain especially cereals in Kenya. Kenya Bureau of Standards (KEBS) recently banned five maize flour brands, citing high aflatoxin levels. They also suspended seven peanut butter products and permits their parent companies over contamination. huge losses encountered these calls for concerted efforts to manage cereals. Aflasafe,...
A magnetically active nanocomposite material has been synthesized from the reaction mixture of magnetite core iron nanoparticles electrostatically coated with SiO 2 , hydrotalcite nanosheets ([Eu 8 (OH) 20 (H O) n ] 4+ ), and decatungstophosphate anion ([ α -PW 10 O 36 7− ]). The resulting material, denoted as Fe 3 4 @SiO @LEuH@PW is demonstrated to effectively adsorb chromate anions aqueous solutions. adsorption isotherms fit Langmuir model a capacity 23 mmol·g −1 after 42 minutes at 25°C....
Wound management is key to healing. Poorly managed wounds lead abnormal biological reactions and complications. Microorganisms, bacteria or fungi, infect such leading their chronic nature. Gold nanoparticles (Au NPs) show wound healing properties. In addition, ethnobotanical information from Siaya County in Kenya shows the leaves of Physalis peruviana L. be effective management. A combination Au NPs leave extracts through a one pot biogenic synthesis leads new substance. The was done at room...
