Evaluation of selected botanicals as insecticides against cabbage insect pests in Tanzania
(NM-AIST, 2022-06)Synthetic pesticides are frequently and unwisely used to control cabbage insect pests by smallholder farmers despite the environmental pollution and insect pests’ resistance development. This work assessed the insecticidal ... -
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 ... -
Photocatalytic degradation of azo dyes in textile wastewater by Polyaniline composite catalyst-a review
(Elsevier B.V., 2022-09)Azo dyes in industrial textile and dye effluent (5–30%) have become irresistibly recalcitrant and toxic to both treatments and the environment respectively. Global concerns about the persistent nature of these dyes and the ... -
Remediation of Soils Contaminated by Fluoride Using a Fermentation Product of Seaweed (Eucheuma cottonii)
(Hindawi, 2022-10-03)is study investigated the e cacy of fermented seaweed (Eucheuma cottonii) on the remediation of uoride-contaminated soil. e soil was amended with either 1.25, 3.0, or 5.0% (w/w) fermented seaweed (FSW), parallel with ... -
Water Boiling Test of carbonized briquettes produced from charcoal fines using African Elemi (Canarium schweinfurthii) resin as an organic binder
