This study presents the result of a quality assessment of some sachet water sold and consumed in Ishiagu. Four sachets from each Triplicate batch of the six different brands of 50 cL sachet water were sampled from commonly patronized retail shops by the inhabitants of the study areas, physically ex-amined and assessed for their physicochemical and microbiological param-eters using standard analytical procedures to ascertain the level of compli-ance with World Health Organization (WHO) and Nation...

The demand for wood products contributes greatly to deforestation, resulting in severe environmental effects. Each year, almost 18 million acres of forest are destroyed, which is equivalent to 27 soccer fields vanishing every minute. This rapid deforestation exacerbates climate change, habitat loss, and natural resource depletion. As a result, finding alternatives to traditional wood for building applications such as doors, windows, roofing, beams, furniture, and packaging is essential. This stu...

In this study, gel-immobilized fillers were used to conduct partial nitrification experiments, including a small-scale experiment in the laboratory and a pilot experiment in a leather factory. The performance of the filler for partial nitrification was investigated by the small-scale experiment under the reactor start-up condition with low initial ammonia oxidizing bacteria (AOB) relative abundance. Then pilot experiment was carried out for the application of the filler in leather wastewater tre...

This study aimed to characterize and estimate the pollution potential of wastewater discharged into the Mda River, due to effluents from the city’s municipal slaughterhouse, with the goal of formulating recommendations for appropriate treatment to reduce the serious impact on not only public health and the environment, but also on the city’s socio-economic activities. A systematic inventory was conducted over the period from January to December 2018. Furthermore, physico-chemical analyses show t...

In reference to the contribution of natural and anthropogenic activities to pollution levels over Kenya, investigation of the changes in aerosol optical properties during COVID-19 lockdowns was assessed. To achieve its objective the present study used aerosol Optical Depth (AOD), Angstrom exponent (AE) and Single Scattering Albedo (SSA) from Ozone Monitoring Instrument (OMI) and Moderate-resolution Imaging Spectroradiometer (MODIS) satellite sensors, to analyze the variations in aerosol properti...

The Ethiopian economy, largely reliant on the pastoralist system, is significantly impacted by its use in semi-arid regions, ensuring livelihoods and export markets. The study aims to assess the strengths, weaknesses, and overall impact of these initiatives on pastoral communities. Moreover, it explores the resilience factors exhibited by these communities, identifying cultural practices, adaptive strategies, and community-driven approaches contributing to their ability to withstand challenges. ...

Vermifilter, based on earthworm-microorganism synergistic action, could simultaneously achieve the reduction and stabilization of excess sludge environment-friendly. To make vermifilter work more efficiently and steadily, the diameter of ceramsite, filter height, and influent concentration were investigated in this study. The results showed that though larger ceramicite may decrease the rate of suspended solids (SS) reduction and volatile suspended solids (VSS) reduction slightly, it can improve...

Protected areas (PAs) are managed for sustainable conservation of natural resources. While local adjacent communities are dependent on natural resources, there is limited access to the resources in PAs. Hence, debate on the role of PAs in improving local community’s livelihoods often gives rise to conflicts. Solutions to this debate have been hampered by lack of information on the actual community concerns. To address the challenges, focus group discussions (FGDs) were done to identify local com...

EDTA synthesized activated carbon derived from sawdust, was utilized as adsorbent for the removal of Pb(II), Cd(II) and Zn(II) ions from aqueous solutions. The adsorptive characteristics and elemental composition of this activated carbon were studied using SEM and EDX techniques respectively, the analysis revealed that SAC-EDTA contained 71.95% by weight of carbon contents which are requisites for the high adsorption capacity. The effect of initial metals ions concentration, adsorbent dose, cont...
