Heavy metal contamination in vegetables cultivated on a major urban wetland inlet drainage system of Lake Victoria, Uganda
(International Journal of Environmental Studies, 2010-06)The population of the Ugandan capital, Kampala, located close to Lake Victoria, appears to be exposed to risk of ingesting the heavy metals Cadmium (Cd) and Lead (Pb) through vegetables in their diet. Lake Victoria is ... -
Ineffectiveness of Nakivubo wetland in filtering out heavy metals from untreated Kampala urban effluent prior to discharge into Lake Victoria, Uganda
(African Journal of Agricultural Research, 2010-12)The population of the Ugandan capital city of Kampala has dramatically increased since the political turmoil of the 1970s and with it a considerable rise in industrialisation. Few manufacturing plants, however, have ... -
Nitrification in modified sewerage stabilisation ponds prior to discharge into the Ugandan side of Lake Victoria
(International Journal of Environmental Studies., 2010-12-08)Large volumes of wastewater in the Ugandan capital Kampala have seriously polluted Lake Victoria, from which the city draws its freshwater. Untreated effluent drains directly into this lake. In tropical temperatures, ... -
Fatty acid composition of muscle, liver, and adipose tissue of freshwater fish from Lake Victoria, Uganda
(Journal of Aquatic Food Product Technology., 2011)Fish oils may differ in fatty acid (FA) composition depending on diet. Oils extracted from muscle, liver, and adipose tissue of Nile perch (Lates niloticus), Nile tilapia (Oreochromis niloticus), silver fish (Rastrineobola ... -
Small tropical reservoirs and fish cage culture: a pilot study conducted in Machakos district, Kenya
(Aquaculture International., 2011-01-07)The findings of this study provide useful insights into the key aspects of fish cage farming to be considered during setting and overall management of multi-purpose water resources so as to maximise their aquacultural ... -
Fatty acids of polar lipids in heart tissue are good taxonomic markers for tropical African freshwater fish
(African Journal of Aquatic Science, 2011-07)The fatty acid profiles in total, neutral and polar lipids in the heart tissues of five freshwater fish species (Nile perch Lates niloticus, Nile tilapia Oreochromis niloticus, marbled lungfish Protopterus aethiopicus, ... -
Nutrient alterations in Nile perch (Lates niloticus) skins owing to various processing and cooking techniques
(International Journal of Environmental Studies, 2012-01)Nile perch (Lates niloticus) skin is a major substitute for whole fish especially among low-income groups who are especially vulnerable to protein and micronutrient deficiencies. The object of this study was to determine ... -
Characterization and analysis of some natural dyes from selected plants in Uganda
(Makerere University (Unpublished work)., 2012-08)Forty different plant species with potential to yield natural dyes were collected from different parts of Uganda between 2004 and 2008. Extraction of the plant materials was done using distilled water after heating for ... -
A detailed time series assessment of the diet of Lesser Flamingos: further explanation for their itinerant behaviour
(Hydrobiologia., 2013-04-27)We hypothesised that changes in nutritional composition and quality of the pelagic phytoplankton community influence the occurrence of Lesser Flamingo populations in two Kenyan saline– alkaline lakes, Nakuru and Bogoria. ... -
Phytoplankton patterns along a series of small man-made reservoirs in Kenya
(Environmental Monitoring and Assessment., 2014-04-10)We studied nine small man-made reservoirs located in different climate regions of Kenya to get an insight into the relationship between phytoplankton community structure and its environment. The investigated ponds form ... -
