Spatial distribution and temporal trend in concentration of carbofuran, diazinon and chlorpyrifos ethyl residues in sediment and water in Lake Naivasha, Kenya
(Springer, 2012)
Chlorpyrifos ethyl was found to be widely distributed in water and sediment in Lake Naivasha. Higher
levels were reported in sediment (11.2–30.0 ng g-1 dry
weight (dw) in wet season than in dry season (4.7–17.4 ng
g-1 ...
Effects of Production Locations and Plucking Intervals on Clonal Tea Fatty Acids Levels in the Kenya Higlands
(J-STAGE, 2012-05-01)
Tea leaves contain unsaturated fatty acids which are precursors of aroma compounds. Despite uniform plucking practices in Kenya, plain black tea quality varies with locations. Variations in tea aroma
and/or precursors ...
Variations of fatty acids levels in young shoots of clonal tea with location of production and nitrogenous fertilizer rates in the Kenya highlands
(Journal of Agricultural Science and Technology, 2012)
Tea leaves contain unsaturated fatty acids, key precursors of volatile compounds contributing to tea aroma quality. Tea is cultivated in areas with diverse environmental conditions. Nitrogenous fertilizers influence tea ...
The potential of Zea mays, Commelina bengelensis, Helianthus annuus and Amaranthus hybridus for phytoremediation of waste water
(Instituto de Pesquisas Ambientais em Bacias Hidrográficas, 2012-12)
Waste-water from domestic use and from industrial effluent burden the water systems with high levels of heavy metal hence there is need to remove these heavy metals so that the waste water can be recycled for use for ...

Validated RP-UHPLC PDA and GC–MS methods for the analysis of psychoactive alkaloids in Sceletium tortuosum
(Elservier, 2012)
Anecdotal evidence indicates that Sceletium tortuosum has been used as a psychoactive preparation for several centuries. The psychological activity
is attributed to the production of mesembrine-type alkaloids (mesembrenol, ...
