Impact of improper municipal solid waste management on fostering One Health approach in Ethiopia - challenges and opportunities: A systematic review.
Sci One Health
October 2024
Improper disposal of solid waste, predominantly illegal dumping, can lead to severe air and water pollution, land degradation, climate change, and health hazards due to the persistence of hazardous materials. As a result, it is threatening public and animal health, environmental sustainability, and economic development. The One Health approach, which acknowledges the interconnectedness of human, animal, and environmental health, offers a comprehensive solution.

- Municipal solid waste management (MSWM) in Ethiopia is a multi-faceted issue involving various dimensions, and effective planning requires insights into waste generation rates and composition.
- The waste generation rate is 0.38 kg per person per day, with food waste being the largest component; recyclables and organic matter offer significant opportunities for composting and biogas production.
- Challenges such as insufficient political will, weak planning, and poor infrastructure hinder MSWM effectiveness, suggesting a need for increased public awareness, funding, and collaboration among government, industry, and civil society to address these issues.
Chitosan (Ch) is a partially crystalline biopolymer, insoluble in pure water but soluble in acid solutions. It has attracted interest from researchers to prepare solutions using different acid types and concentrations. This research aims to study both the effect of chitosan (Ch) or acetic acid (Ac) concentrations, at different temperatures, on rheological and viscoelastic properties of Ch solutions.

A study on speciation of chromium in soils near Sheba Leather Industry was performed by Flame Atomic Absorption (FAAS) after selective extraction of Cr(VI) using the EPA 3060A method, and oxidizing the Cr(III) residue in the soils with HNO3 and H2O2. The extraction method was evaluated using the spiking method with satisfactory results (recoveries>95% and RSDs<5%). The limit of detection (LOD) for Cr(VI) based on three times the standard deviations of the blank (for n=5) was 0.
