摘要：

Instrumental Neutron Activation Analysis (INAA) was used for the determination of the concentration of thirty-three trace elements in both feed-coal and ash obtained from a coal-fired power station in Nigeria. Ash Enrichment Factors (EFs) were determined for each of the elements and the significance of these factors as a measure of environmental contamination assessed. Most of the elements had EFs that were less than 1 while five of the elements (As, Fe, Hf, Na, Ti) had EFs within the range of 1 - 10. EFs obtained for Mn and U appeared significant.
