Iodine Content in Fish and Other Food Products from East Africa Analyzed by ICP-MS

摘要: Abstract The purpose of this study was to measure the iodine content in sea water fish, fresh and different foods plant origin commonly consumed East Africa order evaluate dietary sources for population selected areas. Fish, food items cereals, vegetables, legumes, salt, tea, were obtained from local market sampling areas Ethiopia, Tanzania, Burundi. In samples also collected. biological dried, homogenized, analyzed by Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) using tellurium as an internal standard. Quality control carried out analysis four standard reference materials (SRM) with certified concentrations. results collected showed that concentration fillet salt fish 5 10 times higher than those highest value 920 μg I/kg wet weight changu. lowest found barbus Lake Awasa only 5–8 weight. skin fillets seemed increase size. were, general, low iodine. Highest values red teff Ethiopia 64 I/kg, while all Mwanza except spinach, contained below limit detection method. As source, do contribute some intake might be importance, especially since other contain small amounts element. addition, contribution surface sampled can importance. However, diet regarded a really good source.
