Dass 4 Chemistry Department, Modibbo Adama University of Technology Yola, Nigeria > Research Paper 2016 8 9 2016 10 22 Cement factory dust (CFD) and Kiln feed dust (KFD) were examined using the indexes of pollution. Mean contamination indexes were calculated for each dusts relative to mean background concentrations of the elements in continental crust. Enrichment factor (EF) result showed significant enrichment of the CFD with Arsenic and Manganese, while Chromium, Iron as moderately enriched. Enrichment trend revealed As > Mn > Fe > Cr > Zn > Co > V. The result for the KFD indicated mercury, Arsenic, antimony, and Manganese to be significantly enriched and the order of the enrichment follows the pattern Hg > As > Sb > Mn > Zn > Fe > Co > Cr > V for the metals studied. The EF values for Zn, Co and V in CFD and Fe, Cr, Co, and V in KFD were within the deficient range which and the measure of EF for As, Mn, Hg and Sb suggest these metals could be of anthropogenic source. The measure of contamination based on pollution index (PI) for CFD indicated As and Mn to have moderate contamination while Cr, Co, Zn, V, and Fe to be at levels below contamination of significance. The trend of pollution according to the PI occurs in the order As > Mn > Fe > Cr > Zn > Co > V for CFD and Hg > Cr > As > Sb > Mn > Zn > Fe > Co > V for KFD. The PI model Categorized Hg, Cr, As and Sb in the KFD as within the medium contamination range. Geo-accumulation index (Igeo) showed CFD to be moderately polluted with As and Mn. Nevertheless, the trend of Igeo values in CFD increases in the order As >Mn> Fe > Cr > Zn > Co > V and Cr > As > Sb >Mn> Zn > Fe > Co >V > Hg for KFD. According to the Igeo, metal contamination in KFD was categorized into unpolluted to moderately polluted for Cr and As while Sb, Mn, Zn, Fe, Co, V, and Hg were classified into practically unpolluted range. The level of contamination of CFD and KFD with heavy metals was generalized by the modified degree of contamination (mCd) model as nil and Pollution load index model classified the dusts as having perfect condition but may require detailed study.
