“…The results of elementary chemical analysis expressed in weight percent of oxides, conducted by Young-Chull and Jae-Min, revealed that the raw material dust of the first grinding process primarily consisted of CaO (41.77%), SiO 2 (11.72%), Al 2 O 3 (3.45%), and Fe 2 O 3 (1.47%) [7]. Ca/Si ratios computed by Asubiojo et al found that soil contamination, due to cement, decreases sharply with distance from the factories and with increasing depth from the surface [8].…”

The study investigated potential toxic elements in soils and food flours for highway pollution using PIXE spectrometry. The contaminated soils and cassava food flours contained higher levels of the elements than their control samples, while comparison with their standard permissible limits followed similar trend which was attributable to anthropogenic influences. These were corroborated by their elevated Enrichment factor, Pollution index and Geoaccumulation index values for the elements, suggesting significant anthropogenically-derived contaminations of the soils. T-test value (0.038) for the elemental composition of the contaminated soils & cassava flours was significant due to considerable higher concentrations of the elements in the soils than the cassava flours. Cross plot analysis result for the contaminated soils and cassava fours showed moderate positive correlation (R 2 = 0.426), indicating inter-element relationship between them. Cluster analysis results for the analyzed elements in the contaminated soil samples indicated that Mn, Fe, V, Cr, Zn, Cl, Ti and S showed closest inter-element clustering and was corroborated by the results of Pearson correlation matrices, while inter-element clustering in the food flour followed the same trend and was also supported by their results of Pearson correlation matrices, validating that the soils and cassava flours were contaminated via similar sources.

“…The damaging consequences of the released dust particles for the soil, flora and fauna of the cement factory neighbourhood could be considerable (Akeredolu 1989;Asubiojo et al 1991). Oleru (1984) also reported higher prevalence of lung-related diseases in cement factory workers compared to control subjects.…”

“…Emitted dusts are naturally eliminated as deposits to the earth surface through dry or wet deposition in rainfall (Asubiojo et al 1991). Large particles (diameter > 1 lm) in the emission have an airborne lifetime of minutes to days (Akeredolu 1989) and are deposited within 1 km radius of the cement factory.…”

A total of 298 fish specimens belonging to seven families were caught during ichthyoplanktonic survey of three rivers within the Ewekoro cement facility catchment area located in southwestern Nigeria. The highest numbers of specimens were caught from Alaguntan (37.0%) and Elebute (36.6%) rivers while 28.9% of the fish samples were collected from Itori River. The fish population and species diversity recorded in the catchment rivers were significantly lower (p < 0.05) than comparative catches from Ewekoro River located about 30 km downstream of the factory operational area. The food items ingested by the specimens across the seasons in the catchment rivers revealed obvious differences in diet with some degree of overlap in the fish trophic preferences. However, the omnivorous species dominated the catches in each of the rivers, irrespective of season. Categorization of the fish specimens based on habitat-related adaptive physiology showed that a significant number of the fish from Alaguntan and Itori Rivers have accessory respiratory organs. The four species with accessory respiratory organs were Polypterus senegalus Curv., Clarias gariepinus C. & V., Ctenopoma kingslayae Gun. and Channa obscura Smith. Of the 12 fish species recorded in the Ewekoro cement facility catchment rivers, only P. senegalus, C. gariepinus, C. obscura and Oreochromis niloticus (Trew.) are valuable food fishes in southwestern Nigeria.
