Bioavailability assessment of hexachlorobenzene in soil as affected by wheat straw biochar
(Elsevier, 2012-05-30)
Biochar incorporation with soil could increase sorption of organic contaminants, thereby reducing their bioavailability. In this study, the effects of wheat straw biochar on the sorption, dissipation and bioavailability ...
Antinociceptive and antiplasmodial activities of cassane furanoditerpenes from Caesalpinia volkensii H. root bark
(Elsevier, 2012-01-01)
The chloroform and ethyl acetate extract (100mg/kg) of Caesalpinia volkensii H. exhibited
significant (P≤ 0.05) antinociceptive activities using hot plate and writhing tests in mice
while the later showed antiplasmodial ...
Quality and yields of black tea Camellia sinensis (L.) O. Kuntze responses to harvesting: A review on experiences from Kenya
(PBS Journals, 2012)
Tea beverages, from tender shoots of Camellia sinensis L., are the most widely consumed fluids after water. The young tender shoots of the plant are harvested using various plucking methods. Incorrect plucking leads to ...
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 ...
Changes in soil properties following conversion of forests into intensively managed Camellia sinensis L. plantations along a chronosequence.
(International Society of Tea Science, 2012)
Tea in Kenya was introduced in the beginning of the 20th Century, although commercial cultivation commenced in 1924. The total acreage of tea plantations has steadily increased and currently covers approx. 0.15 million ha, ...
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 ...
