In situ facile green synthesis of Ag–ZnO nanocomposites using Tetradenia riperia leaf extract and its antimicrobial efficacy on water disinfection
(Springer Nature Limited, 2022-09-13)
In this work, Ag–ZnO nanocomposites were prepared by a green synthesis route using aqueous leaf extract of Tetradenia riperia and investigated for antibacterial activity against Escherichia coli and Staphylococcus aureus. ...
Antibiotic-resistant microbial populations in urban receiving waters and wastewaters from Tanzania
(Elsevier, 2023)
Antimicrobial resistance against certain medications in the pathogenic microbial community is globally increasing due to the continual discharge and disposal of pharmaceuticals in the environment. The phenomenon resulted ...
The Potential of Valorized Sisal Decorticated Waste in Rearing of Black Soldier Fly
(MDPI, 2022-12-23)
The use of sisal decorticated waste (SDW) for various applications is limited due to its high acidic content. This is the first study of its kind regarding the use of SDW as a substrate for the growth of the black soldier ...
Hydroxyapatite-activated seaweed biochar for enhanced remediation of fluoride contaminated soil at various pH ranges
(Elsevier, 2022-12-10)
This study investigated the defluoridation efficiency of hydroxyapatite-activated seaweed (Eucheuma Cottonii) biochar (HSB) at various soil pH ranges (3–11) while monitoring the impact of contact time (30 min - 2.5 h), ...
The pharmaceutical disposal practices and environmental contamination: A review in East African countries
(Elsevier, 2022-11-24)
The aim of this review was to analyze the available information on methods used in disposing of unused or expired pharmaceuticals in East African countries and the possibility of environmental contamination. There are some ...
Adsorption-capacitive deionization hybrid system with activated carbon of modified potential of zero charge
(Elsevier, 2023-02-15)
In this study water solutions are desalinated with carbon electrodes of modified surface charges. The idea is to endow the electrodes with the ability to physically adsorb salt ions without applying potential so as to save ...
Cockle (Anadara granosa) shells-based hydroxyapatite and its potential for defluoridation of drinking water
(Elsevier, 2022-03-03)
The present study describes the synthesis and characterization of a hydroxyapatite (HAp)-based adsorbent derived from biogenic cockle (Anadara granosa) shells for the defluoridation of drinking water. The raw cockle shells ...
What influences individuals to invest in improved sanitation services and hygiene behaviours in a small town? A formative research study in Babati, Tanzania
(PLOS ONE, 2022-07-21)
Sub-Sahara African countries face immense challenges in ensuring adequate sanitation and hygiene behaviours to the rapidly growing populations. Attempts to address these challenges require empirical evidence to inform ...
Contribution of Illicit Drug Use to Pharmaceutical Load in the Environment: A Focus on Sub-Saharan Africa
(Hindawi, 2022-07-08)
Illicit drug abuse and addiction are universal issues requiring international cooperation and interdisciplinary and multisectoral
solutions. ese addictive substances are utilized for recreational purposes worldwide, ...
Crustacean derived calcium phosphate systems: Application in defluoridation of drinking water in East African rift valley
(Elsevier B.V., 2018-04-05)
Calcium phosphate adsorbents, derived from prawns and crabs shell biomass wastes have been developed using wet chemistry and low temperature treatment. The adsorbents were characterized by X-ray diffractometry and Fourier ...
