摘要：

The concentrations of some essential micronutrient elements leading to short-lived activation products in four Nigerian vegetable based oils (palm oil, palm kernel oil, sheabutter and groundnut oil) have been determined by neutron activation analysis using a small research reactor. One sample of each material was analysed and presented as an introduction for further investigations. Results indicate that the concentration range of the elements are 19.4-44.0 μg/g for Al; 30.0-81.0 μg/g for Ca; 11.9-60.4 μg/g for Cl; 1.43-5.96 μg/g for Cu: 7.3-28.1 μg/g for Mg; 0.47-1.69 μg/g for Mn; 17.5-72.8 μg/g for Na and 0.04-4.07 μg/g for V. The experimental procedure is suitable for routine determination of micronutrient element in foods for control and monitoring purposes.
