Occurrence of microplastics in surface water, superficial sediments and Nile tilapia (Oreochromis niloticus) from fish breeding areas of Lake Victoria Faith Atukwatse, Christine Betty Nagawa, Timothy Omara, Christine Kyarimpa, Solomon Omwoma Lugasi, Rose Basooma, Gerald Kwikiriza, Patrick Ssebugere, Gladys Namuswe Bwanika Discover Applied Sciences, 2026 Lake Victoria, the largest African Great Lake and the world’s second largest freshwater lake by surface area has several bays and inlets along its shoreline, which serve as breeding grounds for fish. The ecological and economic importance of these bays are now under threat due to rapid urbanization and agricultural expansion that have introduced pollutants into them. Using stereomicroscopy and micro-Fourier transform infrared (µ-FTIR) imaging, we investigated the occurrence of microplastics (MPs) in surface water (n = 12), superficial sediments (n = 12) and Nile tilapia (Oreochromis niloticus, n = 66) from four fish breeding areas (Port Bell, Masese, Kigaya and Nabulugo) on the northern shores of Lake Victoria. The frequency of MPs detection was 100%, 83.3% and 56.1% in surface water, sediments and fish samples, respectively. The corresponding microplastic counts were 22–60 particles/L, 2–10 items/kg and 1–16 items/fish. Port Bell and Masese that are in close proximity to urban areas had higher microplastic contamination than Kigaya and Nabulugo, which are in less disturbed sites (P > 0.05). Across all the samples, filaments were the most dominant form of MPs (43.1–100%), followed by fragments (7.8–55.6%), fibers (2.2–21.4%), foams (5.3–31.1%) and pellets (1.7–6.7%). The particles were confirmed by µ-FTIR to contain mainly polyethylene, polypropylene and polystyrene. Total length of fish from Nabulugo showed a strong and significant negative correlation (ρ = – 0.753, P = 0.01) with the number of MPs ingested, indicating that larger fish are associated with lower microplastic loads. Branchial intrusion of MPs in Oreochromis niloticus provide evidence of potential direct human exposure to MPs through consumption of this fish species. These results indicate that there is a growing threat of MPs to fishery sustainability and food safety in Lake Victoria, emphasizing the need for targeted policy interventions to mitigate plastic pollution in catchments of fish breeding habitats. Microplastics were found in water, sediments and Nile tilapia, with smaller fish having more pieces. Fish breeding areas near urban settings are more polluted with microplastics than remote locations. The presence of microplastics in tilapia gills indicate a possibility of low level microplastic exposure for individuals who consume the fish with its gills intact.
Fatty acid composition and cholesterol distribution in edible tissues of long-horned Ankole cattle Joseph Wanyama, Justus Kwetegyeka, Hannington Twinomuhwezi, Timothy Omara, Ivan Kiganda Journal of Food Composition and Analysis, 2026 Ankole cattle is a vital genetic resource and an economic asset in East and Central Africa, usually reared for their beef and milk. For the first time, the total lipid content, fatty acid composition and cholesterol concentration in beef of Ugandan long-horned Ankole cattle were determined using gas chromatography-mass spectrometry and high performance liquid chromatography. Significant variations in the total lipid content, fatty acid composition and cholesterol concentration were observed among the different samples, with the liver and kidneys possessing the highest values (P < 0.05). The fatty acid composition followed the order: monounsaturated fatty acids> saturated fatty acids > polysaturated fatty acids. Nutritional indices indicated that the kidney, liver, and heart had better fatty acid compositions. In contrast, the rib, large intestine, and chuck had higher atherogenic and thrombogenic indices, which may be associated with increased risks of cardiovascular diseases when consumed.
Tetracycline residues in milk and beef from the Ugandan Cattle Corridor Justus Mwesigye, Justus Kwetegyeka, Ivan Gumula, Timothy Omara, Ivan Kiganda Journal of Environmental Science and Health Part B Pesticides Food Contaminants and Agricultural Wastes, 2026 Veterinary antibiotic residues in foods of animal origin (FOAO) are of public health concern because they can contribute to antimicrobial resistance, disruption of gut microbiota, hypersensitivity reactions and developmental effects following chronic exposure. This study investigated the occurrence of six veterinary tetracyclines (oxytetracycline, tetracycline, doxycycline, chlortetracycline, demeclocycline and methacycline) in FOAO from the Ugandan Cattle Corridor districts of Nakaseke and Nakasongola. Raw milk, muscle tissue, liver and kidneys were analyzed for tetracyclines using high performance liquid chromatography and liquid chromatography-tandem mass spectrometry. Districtwise analysis revealed a moderate prevalence of tetracycline residues in milk (5.3-42.1%) and beef (7.7-69.2%), with oxytetracycline being the most detected. Of these, 5.3-69.2% of the samples had oxytetracycline, methacycline and tetracycline concentrations exceeding their maximum residue limits established by the European Union Commission Regulation No. 37/2010. These results provide baseline data on the presence of tetracycline residues in marketed FOAO from the Ugandan Cattle Corridor. It emphasizes the need for strengthened antimicrobial stewardship, enforcement of veterinary drug withdrawal periods, and routine national antimicrobial residues monitoring in FOAO.
Nutritional and sensory characteristics of local and hybrid East African Highland cooking bananas: Implications for breeding programs Willy Nelson Kisenyi, Pricilla Marimo, Moses Matovu, Kephas Nowakunda, Ediriisa Mugampoza, Samuel Gafuma, Timothy Omara, Ivan Kiganda Jsfa Reports, 2026 Background Bananas ( Musa species) are an important staple food and cash crop in many parts of the world. The East African Highland cooking bananas form the backbone of food security for millions of Ugandans. The demand for high quality cooking bananas is thus closely linked to their sensory characteristics (which drive consumer preference) and physicochemical properties, which, on the other hand, influence their nutritional and culinary values. We explored the relationship between nutritional composition, sensory characteristics, and physicochemical properties of 23 cooking banana cultivars from Uganda. These included officially released hybrids ( n = 2), hybrids under evaluation ( n = 12), female parent cultivars used in breeding ( n = 3), and popular local East African Highland bananas ( n = 6). Results Local cultivars (Mpologoma, Mbwazirume, and Muvubo) had significantly higher moisture, crude fat, ash, protein, and amylose contents compared to the hybrids ( p < 0.05). Hybrid cultivars (N2, N6, and M33) had the highest dry matter contents, while the other hybrid cultivars had higher phenolic contents. Sensory evaluation identified key desirable characteristics of cooked bananas to be color, texture, aroma, taste, and astringency. Some hybrid cultivars (N21, N15, N11, N8, 17914S‐24, N2, and N6) had lower sensory scores compared to others (M32, N17, M9, M33, and N24) and the local cultivars. Principal component analysis and Pearson correlation revealed positive relationships between physicochemical properties (titratable acidity, pH, phenols, tannins, starch, amylose, moisture, and minerals composition) and desirable sensory characteristics (yellow homogeneous color, sweet and matooke tastes, and low astringency). Conclusion Breeders could select for the attributes with positive relationships to enhance the adoption and consumption of the hybrid cooking bananas. However, further work is needed to establish the acceptability thresholds of the attributes.
Not one-size-fits-all: µ-FTIR and pyrolysis GC-MS for complementary analysis of microplastics in eutrophic surface water Timothy Omara, Barbora Benetková, Ivan Sumerskii, Patrick Ssebugere, Christine Kyarimpa, Solomon Omwoma Lugasi, Thomas Rosenau, Christine Betty Nagawa, Stefan Böhmdorfer Analytical and Bioanalytical Chemistry, 2026 This study reports large microplastics found in Lake Victoria through an analytical workflow that combines the complementary methods stereomicroscopy, micro-Fourier transform infrared (µ-FTIR) spectroscopy and pyrolysis gas chromatography-mass spectrometry (Pyr-GC-MS) for the quantification of 11 environmentally relevant microplastic polymers. Algae-rich surface water samples ( n = 18) were trawled using a 0.3 mm manta net from Lake Victoria, the world’s largest tropical lake. Stereomicroscopy as a determinant analytical technique detected 191 particles, which were primarily blue fragments and fibres. Polyethylene and polypropylene were the dominant polymers identified by µ-FTIR. Pyr-GC-MS allowed the detection and quantification of microplastics (MPs) with LOD and LOQ of 0.01–14.7 µg and 0.03–49.1 µg. Polyethylene (0.058–0.34 µg/L), polypropylene (0.024 µg/L and 0.043 µg/L), nylon 6 (0.0051–0.064 µg/L), nylon 66 (0.0022–0.084 µg/L), poly(ethylene terephthalate) (0.0029–0.027 µg/L) and poly(methyl methacrylate) (0.0036 µg/L) were quantified. µ-FTIR was found to be suitable for the identification of the most abundant polymers in the 0.3–4.9 mm size range whereas Pyr-GC-MS afforded the quantification of seven polymers, most of which were not detected by µ-FTIR. This complementary workflow gave a wider perspective on MP loading, providing both polymer concentrations and physical characteristics (sizes, colours, forms and count) of the MPs. Graphical abstract
Ecological and Human Health Risks from Potentially Toxic Elements in Environmental Matrices of Kiteezi Landfill, Uganda Emmanuel Ebbu, Irene Nalumansi, Ivan Kiganda, Caroline Kiwanuka Nakiguli, Patrick Onen, Simon Ocakacon, Christopher Adaku, Timothy Omara, Emmanuel Ntambi Journal of Xenobiotics, 2025 By the time of this study, Kiteezi landfill was Uganda’s largest waste disposal site and received substantial volumes of municipal solid waste. In the present study, water (n = 36), leachates (n = 36), superficial sediments (n = 30), and Colocasia esculenta corms (n = 6) were sampled from Kiteezi landfill in the dry and wet seasons of 2022 before its tragic collapse in 2024. The physicochemical parameters (pH, electrical conductivity, temperature, and oxidation–reduction potential) and concentration of potentially toxic elements (As, Cu, Cr, Pb, and Zn) were analyzed using standard methods and inductively coupled plasma-optical emission spectrometry, respectively. Significant seasonal variations (p < 0.05) were observed for all the physicochemical parameters of water and leachates except temperature. Further, significantly higher concentrations (p < 0.05) of potentially toxic elements (PTXEs) were quantified in environmental matrices sampled during the dry season than the wet season. Arsenic and Pb concentrations in water surpassed their WHO permissible limit of 0.01 mg/L. The concentrations of PTXEs were higher in downstream samples (p < 0.05), indicating that landfill activities led to their enrichment in matrices near the facility. Ecological and pollution risk indices indicated that there is severe enrichment of Cu and Zn in the sediments, with dry season downstream samples having contamination factors and geoaccumulation indices of 539.3 and 74.7 and 8.5 and 5.6, respectively. Although ingestion of water may not cause probable health risks, consumption of Colocasia esculenta corms could lead to non-carcinogenic and cancer health risks in both children and adults (hazard indices = 0.085–189.0 and total cancer risk values of 7.33 × 10−6–4.87 × 10−3). These results emphasize the need that any new replacement for Kiteezi landfill should be properly planned and managed to mitigate potential environmental pollution with xenobiotics.
Bioaccumulation and Transfer of Potentially Toxic Elements in the Yam-Soil System and Associated Health Risks in Kampala’s Luzira Industrial Area Gabson Baguma, Gadson Bamanya, Hannington Twinomuhwezi, Allan Gonzaga, Timothy Omara, Patrick Onen, Simon Ocakacon, Christopher Angiro, Wilber Waibale, Ronald Ntuwa Journal of Xenobiotics, 2025 Rapid industrialization in peri-urban centers has accelerated the accumulation of potentially toxic elements (PTEs) in agricultural soils, with implications for food safety and public health concerns. This study quantified PTEs (Cu, Cd, Cr, Pb, and Zn) in soils and yam (Colocasia esculenta) tubers from Kampala’s Luzira Industrial Area. Soil contamination levels were evaluated using the geoaccumulation index (Igeo), contamination factor (CF), and pollution load index (PLI), while soil-to-crop transfer of the PTEs was assessed using the biological accumulation factor (BAF). Statistical analyses (One Way Analysis of Variance, Pearson bivariate correlation, and Principal Component Analysis) were applied to identify relationships among PTEs and sampling sites. Soils exhibited marked industrial influence, with PTE concentrations in the order Zn > Pb > Cu > Cr > Cd. The PLI values above unity confirmed cumulative pollution, with hotspots dominated by Zn, Pb, and Cu. Yam tubers contained lower PTE concentrations but reflected a similar contamination pattern as in the soils. The BAF values were <1 for all the PTEs except Zn, pointing to its greater solubility and mobility in the area’s acidic soils. Health risk assessment indicated that yam consumption was the dominant exposure pathway, with hazard indices (HI) for children exceeding the safe threshold at all industrial sites (HI = 1.14–2.06), and total cancer risks (TCR) ranging from 1.27 × 10−4 to 5.83 × 10−4, well above the US EPA limit. For adults, the TCR also surpassed 1 × 10−4 at sampling points SP3 and SP4. These results found potential transfer of the PTEs from soils into yam tubers, with Cd and Cr being the key drivers of dietary risk.
In silico Antimycobacterial Evaluation of Compounds Isolated from Kigelia africana Stem Bark Ivan Gumula, Mary Achiro, Sarah Kiwanuka Nanyonga, Denis Akampurira, Patrick Onen, Ronnie Tumwesigye, Timothy Omara Natural Product Communications, 2025 Objective Tuberculosis (TB) is among the major causes of mortality due to a single infectious bacterium. The burden of TB is higher due to multidrug-resistant Mycobacterium tuberculosis strains, which lead to treatment failures. The present study conducted in silico studies of bioactive compounds isolated from Kigelia africana (Lam.) Benth stem bark. Methods Pure compounds were isolated from dichloromethane/methanol stem bark extract of Kigelia africana after repeated column chromatography. The chemical structures of the isolated compounds were established based on 1 H NMR, 13 C NMR and 2D NMR (COSY, HSQC and HMBC) spectroscopy. In silico analyses were performed to assess the drug-likeness, pharmacokinetics and antibacterial potential of the compounds against target proteins (4QIJ and 5HKF, 5L3J and 8GZY, and 2QIL) from M. tuberculosis , Escherichia coli , and Staphylococcus aureus , respectively. Results Four compounds: demethylkigelin, tyrosyl butyrate, stearic acid and stigmasterol were characterized. In molecular docking studies, the compounds showed binding affinities ranging from −4.4 to −9.3 kcal/mol against target proteins 4QIJ, 5HKF, 5L3J, 8GZY and 2QIL. Stigmasterol (L4) had the highest affinity against the highest binding affinity, with a score of −9.3 kcal/mol against S. aureus protein 2QIL. It also showed strong affinities against M. tuberculosis (4QIJ and 5HKF) and E. coli (5L3J and 8GZY) targets. In silico toxicity profiling predicted tyrosyl butyrate and stearic acid to be relatively safe whereas demethylkigelin and stigmasterol showed potential respiratory and cardiotoxic effects that needs further safety evaluation. Conclusion Kigelia africana stem bark possesses bioactive compounds that are potential inhibitors of M. tuberculosis with good to better binding affinities and stable interactions. Future studies should validate the in vitro and in vivo bioactivity as well as toxicity of the compounds.
