Comparative Study of Pb2+ Removals and Isotherms by Physically - and Chemically - Modified Agro - Wastes from Tanzania
(Gwangju Institution of Science and Technology, 2016)
Materials and Methods Raw corn and rice husk were washed several times using DIW to remove extraneous dirt and contaminants. The husks were then dried at 110 ºC overnight to remove moisture. Dried husks were then ground ...
Innovations and Sustainability: The Case of Improved Biomass Stoves' Adoption and Use in Tanzania
(Lund, Sweden – Spring, 2009)
The adoption and continued use of improved stoves in the developing countries is of social, economic
and environmental concern. In most developing countries, biomass-based energy accounts for more
than 90% of all household ...
Modeling and optimization of independent factors influencing lead(II) biosorption from aqueous systems: A statistical approach
(Elsevier, 2022-07)
Lead, [Pb(II)] is a major hazardous contaminant that exists in the soil, surface, and groundwater as a result of human activities. It is carcinogenic in nature and causes damage to the liver, kidney, and bones as well as ...
A comprehensive review on the decontamination of lead(II) from water and wastewater by low-cost biosorbents
(Royal Society of Chemistry, 2022-04-12)
The disadvantages of conventional methods in water and wastewater management including the demand
for high energy consumption, the creation of secondary toxic sludge, and operation cost are much too high
for developing ...
Quantitative assessment of metal contamination and associated pollution risk in sediments from the Mara River in Tanzania
(Springer Nature Switzerland AG., 2020-10-21)
For most rivers in sub-Saharan Africa, information about pollution indices related to sediments is sparse. Sedimentological research of rivers that empty into Lake Victoria is highly patchy and wide apart. The present study ...
Rainfall and temperature changes under different climate scenarios at the watersheds surrounding the Ngorongoro Conservation Area in Tanzania
(Elsevier, 2022-04)
Considering the high vulnerability of Northern Tanzania to climate change, an in-depth assessment at the local
scale is required urgently to formulate sustainable adaptations measures. Therefore, this study analyzed the ...
The influence of gold mining on radioactivity of mining sites soil in Tanzania
(International Journal of Environmental Quality, 2022-02-17)
The activity of 226Ra, 232Th and 40K in soil samples were measured by gamma spectrometry using high purity germanium detector. The study involved 40 samples from four divisions: 10 samples each were
drawn from the control ...
