Trace metals in Lates niloticus and Rastrineobola argentea samples for human consumption at Winam Gulf of Lake Victoria
(University of Nairobi, 2009)
Trace metals were determined in the two most abundant fish species in the Winam Gulf of Lake Victoria (Lates niloticus and Rastrineobola argentea). The results show that the concentratios of the metals have no significant ...
The fate and dissipation of surface applied 14C‐DDE in a tropical soil
(University of Nairobi, 1996-10-19)
The results of a study conducted to follow the dissipation, distribution and fate of 14C‐p,p'‐DDE in a tropical soil under field conditions are reported. 14C‐DDE was applied to soil columns in PVC cylinders (of lengths: ...
Interference effects of different metals in the atomic absorption spectrophotometric determination of chromium
(University of Nairobi, 1979)
The interfering effect of thirty six metal salts on chromium absorbance in the air- acetylene flame has been studied. The interference does not depend on the boiling point of the added foreign metals or particle size as ...
The dissipation and degradation of methoxy‐14C malathion in soil under tropical conditions
(University of Nairobi, 2000)
l4C‐malathion[S‐1,2‐bis(ethoxycarbonyl) ethyl O,O‐dimethyl phosphorodithioate] has been studied in soil under tropical field conditions by applying the 14C‐malathion pesticide to soil in Polyvinyl chloride (PVC) pipes and ...
Fate of 14c‐P,P'‐DDT in Kenyan tropical soils
(University of Nairobi, 1994)
The dissipation and degradation of 14C‐p,p'‐DDT in tropical soils of Nairobi were studied under field and laboratory conditions for a period of six months. DDT was found to dissipate much more rapidly from the soil under ...
