dc.description.abstract Assessment of Uranium levels in selected food groups and products with the associated health effects to the residents of Bahi District was carried out. The objective was to come up with information on whether these food groups contain significant amounts of Uranium and if the community has been affected by uranium related diseases. This was done to bring the awareness to the vulnerable communities and Tanzanian Government in general on the environmental and health hazards posed by the presence of Uranium deposits in the study area. Selected food groups and products used to assess uranium levels were maize, finger millet, rice, cassava leaves, salt, soda ash, fish, flamingo meat and water. These food groups were collected from three different villages of Bahi district. The levels of uranium in the named food groups and products (in μg kg–1) were determined by using ICP–OES instrument. Maize and rice had uranium concentration below detectable limit (<10), millet was found to range 11.88 – 25.13; cassava leaves ranged 12.37 – 13.83. Fish had uranium content of 17.98 in the skin where as muscles had uranium level below detactable limit. Flamingo bird had uranium level of 31.78 in the liver , where as other tested parts had below detectable limit. Soda ash was found to have uranium content of 1910, whereas salt had uranium content below detectable limit. The results for water from different sources in three villages have shown that, in Ilindi village, Playa lake water had uranium concentration of 1233, while drinking water from one well had uranium content of 95.4, water from a well used for irrigation had uranium content below detectable limit. In Mpamantwa village, the water from one well had uranium content of 16.7 whereas other sources had uranium level below detectable limit. In Bahi village, the water from one well had uranium level below detectable limit while river water had uranium concentration of 67.6 and another well had uranium content of 16.6. Secondary data from hospitals have shown that Bahi communities have not been affected by uranium exposure through en_US
