Assessment of heavy metals in benthic macroinvertebrates, water and sediments in River Isiukhu, Kenya
(Environmental Monitoring and Assessme, 2019-10-16)
A major ecological challenge facing freshwater resources such as rivers is the influx of chemical contaminants from anthropogenic sources. A report on the levels of heavy metals, namely Zn, Cu, Cr, Cd and Pb in benthic ...
Biodegradation of carbofuran in soils within Nzoia River Basin, Kenya
(Journal of Environmental Science and Health, Part B, 2015-04)
Carbofuran (2,3-dihydro-2,2-dimethylbenzofuran-7-yl methylcarbamate) has been used within the Nzoia River Basin (NRB), especially in Bunyala Rice Irrigation Schemes, in Kenya for the control of pests. In this study, the ...
Comparative studies in electrochemical degradation of sulfamethoxazole and diclofenac in water by using various electrodes and phosphate and sulfate supporting electrolytes
(Journal of Environmental Science and Health, Part A, 2016-06-23)
In this study, the electro-oxidation capacities of Na2SO4 and potassium phosphate buffer supporting electrolytes were tested and compared for destruction of the sulfamethoxazole (SMX) and diclofenac (DCF) on platinum (Pt) ...
Analysis of Spatial and Temporal Levels of Heavy Metals in Water, Sediments and Fish in Sosiani River
(International Journal of Environmental Bioremediation & Biodegradation, 2019-10-09)
The objective of the study was to examine spatial and temporal levels of heavy metals in water,
sediments and fish in Sosiani River. This study was an experimental design approach in which a scientific analysis
was done ...
Fish Tissue Bio-concentration and Interspecies Uptake of Heavy Metals from Waste Water Lagoons
(Journal of Pollution Effects & Control, 2016-01)
Fish products may be important vectors of human exposure to heavy metals. However the understanding of how heavy metals bioconcentrate in different fish species (sp.) through contaminated environments such as wastewater ...
Derivatization Reactions and Reagents for Gas Chromatography Analysis.
(Advanced Gas Chromatography - Progress in Agricultural, Biomedical and Industrial Applications, 2012-03)
Derivatization reactions are meant to transform an analyte for detectability in Gas Chromatography (GC) or other instrumental analytical methods. Derivatization in GC analysis can be defined as a procedural technique that ...
Caffeine and Ciprofloxacin Adsorption from Water onto Clinoptilolite: Linear Isotherms, Kinetics, Thermodynamic and Mechanistic Studies
(South African Journal of Chemistry, 2019-01)
In this study, clinoptilolite was used to sequester ciprofloxacin (CIP) and caffeine (CAF), two emergent contaminants, from aqueous solution using batch equilibration method and the effects of contact time, pH, initial ...
Per- and polyfluoroalkyl substances in selected sewage sludge in Nigeria.
(Chemosphere, 2013-07-03)
Levels of seven major perfluoroalkyl carboxylates (PFCAs) and three perfluoroalkyl sulfonates (PFSAs) were analyzed for the first time in sludge from wastewater treatment plants from Nigeria. Measurements were performed ...
Bioaccumulation of perfluoroalkyl acids in dairy cows in a naturally contaminated environment.
(Environmental Science and Pollution Research, 2013-05-04)
Beef and dairy products may be important vectors of human exposure to perfluoroalkyl acids (PFAAs), but the understanding of how PFAAs are accumulated and transferred through agricultural food chains is very limited. Here, ...
