Heavy metal concentrations in sediments, Soil, waters and mosses around Pan African paper mills, Webuye
(Maseno university, 2010)
Atomic absorption spectroscopic analysis of soils, sediments, water and mosses in the
vicinity of Pan African Paper Mills, Webuye, Kenya has revealed the prevalence of the
heavy metals Cu, Zn, Cr, Cd, Fe and Pb in the ...
The effects of nitrogenous fertilizers on selected physiochemical parameters and heavy metal loads within Nzioa nucleus sugarcane estate farms in western Kenya
(Maseno university, 2010)
Continued use of nitrogenous fertilizers and biosolids in farming is known to
affect the soil pH of the farms leading to acidic environment that promotes solubility;bioavailability and mobility of heavy metals. In addition, ...
Influence of area of production, nitrogenous Fertilizer rates and plucking intervals on the \ production of fatty acids in clonal tea '(Camellia sinensis (L.O) Kuntze) leaves
(Maseno university, 2011)
Tea, Camellia sinensis, is widely grown in the highlands of Kenya for manufacture of mainly
black tea. The most costly inputs in tea cultivation are nitrogenous fertiliser and plucking which
are key determinants of yield ...
The effects of zeolite x and y on degradation kinetics of P, P'-DICHLORODIPI-IENYLYTRICIILOROETHANE (DOT) in natural water
(Maseno university, 2010)
The study was on degradation kinetics of pesticides in water by zeolites. Pesticides
are never target specific and as such, aerial dissipation of pesticides is potentially
\
hazardous to man and environmental biodiversity. ...
Monitoring of carbofuran residues in Laikipia and Isiolo districts in Kenya for ecological risk Assessment
(Maseno university, 2010)
Granular carbofuran which was widely used to control agricultural pests in Isiolo and
Laikipia districts was also misused by local farmers and pastoralists to kill predators
leading to massive deaths of Gyps vultures ...
Indoor levels of polycyclic aromatic Hydrocarbons from wood burning in Rural houses in western Kenya
(Maseno university, 2011)
Western Province of Kenya has prevalence of grass-roofed traditional houses, where
cooking is done in open fire places using various biomass types, which leads to
accumulation of soot under the roofs. Polycyclic Aromatic ...
Phytochemical evaluation of Elaeodendron buchananii stem Bark for microbial activities
(Maseno university, 2010)
Public health is under serious threat due to wide array of emerging and re-emerging
infections as a result of resistance of microorganisms to first line drugs. Despite the wide
availability of clinically useful antifungal ...
Assessment of polycyclic aromatic hydrocarbons in .Fish, meat and the effect of cooking on their Concentrations in meat as sources of human exposure in Winam gulf region of Lake Victoria
(Maseno university, 2011)
Polycyclic Aromatic Hydrocarbons are of concern m environmental chemistry
because they are known or suspected carcinogens and/or toxicants. Fish is a major
indicator of the existence of PARs in aquatic environment and ...
Assessement of polycyclic aromatic hydrocarbon(PAH) distribution in sediment and water samples of Winam gulf,Lake Victoria,Kenya
(Maseno university, 2008)
Polycyclic aromatic hydrocarbons (PAH) commonly refers to a large class of organic
compounds containing two or more fused aromatic rings. They comprise unsubstituted
parent PAH and their alkyl-substituted derivatives. ...
Hydrothermal crystallization of zeolite catalysts using kaolin and volcanic ash materials for biodiesel synthesis from Jatropha curcas and waste cooking oils
(Maseno university, 2022)
Although biodiesel is a promising alternative source of energy, the cost of its production remains high because of the use of expensive feedstocks and catalysts. Zeolites derived from clay and volcanic ash as alternative ...
