Effects of location of production, fertilizer rates and plucking intervals on mature leaf nutrients of clone TRFK 6/8 in East Africa.
(Tea Research Foundation of Kenya, 2011)Mature tea leaf has been adopted in East Africa for nutrients diagnosis to guide remedial applications of nutrients and cushion the plants from possible deficiencies that would affect yields and quality. Although it ... -
Effects of genotype, environment and management on yields and quality of black tea Authors
(Springer Netherlands, 2011)The tea beverages processed from the young tender shoots of Camellia sinensis (L.) O. Kuntze, are claimed to be the most widely consumed fluids after water. The tea plant originates from the point of confluence of ... -

Spartial and seasonal variations in concentrations of polycyclic aromatic hydrocarbons in water and sediment of Kisumu City Bay of Winam Gulf, Lake Victoria-Kenya
(2009-11-01)Seasonal and offshore concentration variations for selected sixteen priority pollutant polycyclic aromatic hydrocarbons (PAHs) in surface sediments and water of Car Wash and Kisat areas of Winam Gulf, Lake Victoria, ... -
High concentrations of polycyclic aromatic hydrocarbons found in water and sediments of car wash and kisat areas of Winam Gulf, Lake Victoria-Kenya
(Springer-Verlag, 2009-01-09)Mean concentrations of selected USEPA priority polycyclic aromatic hydrocarbons (PAHs) in surface sediments and water samples from Car Wash and Kisat areas of Winam Gulf, Lake Victoria in Kenya have been determined ... -
A comparison of adsorption equilibrium, kinetics and thermodynamics of aqueous phase clomazone between faujasite X and a natural zeolite from Kenya
(The South African Chemical Institute, 2015)In this study, a well-studied synthetic faujasite X (FAU-X) zeolite and a recently discovered natural zeolite material from Kenya (NZ-K) were compared for their efficiency in removal of clomazone, a herbicide and water ... -
Removal of tebuconazole from wastewater by zeolite X: kinetics and thermodynamics studies
(2014-08)Tebuconazole, a widely used fungicide is toxic to the environment and has been reported as a water contaminant. In this study, the adsorption of aqueous solution tebuconazole onto faujasite X (NaX) was investigated in ... -
Effects of zeolite X on dissipation of hexazinone from agricultural waste waters in Western KenyaEffects of zeolite X on dissipation of hexazinone from agricultural waste waters in Western Kenya
(2013)Dissipation of hexazinone in Zeolite X treated wastewater followed pseudo first-order kinetics giving a calculated half-life of 41 days compared to a half-life of 144 days in untreated wastewater. The herbicide degraded ... -
Effects of faujasite X and Y zeolites on the 1, 1, 1-trichloro-2, 2’bis (p-chlorophenyl) ethane (DDT) degradation during water purification
(2013)The ability of zeolites to abstract and denature organochloride pesticides finds application in water purification practices. In this study, activated faujasite X and Y zeolites were separately exposed to 1, 2 and 4 ... -
The mechanism of 2-chlorobiphenyl oxidative degradation by nanoscale zero-valent iron in the presence of dissolved oxygen
(Springer Berlin Heidelberg, 2017-11-01)It has recently been demonstrated that the addition of nanoscale zero-valent iron (nZVI) to oxygen-containing water or soil aquifers results in the oxidation of organic compounds. However, there has been little insight ... -
Fate processes of chlorobenzenes in soil and potential remediation strategies: A review
(Elsevier, 2017-06-01)Chlorobenzenes (CBs) are a group of organic pollutants that pose a high environmental risk due to their toxicity, persistence and possible transfer in the food chain. Available data in literature show that CBs are ... -
Effects of nitrogenous fertilizer rates, plucking intervals and location of production on the micronutrient levels of clonal black tea.
(International Society of Tea Science, 2014)Micronutrients are important to both animal and plant life. In plants, the levels can vary widely due to biotic and abiotic factors. Tea is widely grown and its beverages are claimed to be the most widely consumed ... -
