This paper examines the effect of externalities (environmental pollution) generated by the activities of the West African Portland Cement Company (WAPCO) PLC in its two plants at Sagamu and Ewekoro on the profitability of Agricultural production in its areas of operation. To this end, study area is divided into two areas-those affected by the operation of the factories, and those not affected (control). Farmers were selected from each area for interview by means of a probabilistic sampling technique. Information was collected by means of a pre-tested structured questionnaire from both sets of respondents. Costs and returns were estimated for farmers located in each area; then the probability of farm enterprises as well as the efficiency of resource utilization in the affected area was compared with those in the control area. The study shows that (i) the main environmental pollutants generated by the company are dust and noise; thus the inhabitants suffer from air-laden air, cracking of walls of structures as well as soil and water polluted by dust; (ii) farming was more profitable in the control than in the affected area in both zones: For example, the estimated net returns accruing to an average farmer in the affected area was #190,524.25 per hectare while that in the control area was #272,282.20 per hectare; (iii) resource productivity was higher in the control area than in the affected area. For example, farmers in the control area earned N4.72 for every N1.00 expended on labour while their counterparts in the affected area earned N2.18; and (iv) farmers in the affected area incurred additional costs in purifying their water for drinking, attending to their health problems resulting from the activities of the company and effecting repairs on their cracked buildings. The estimated average cost incurred was N24,000 per annum. These findings imply that the operations of the company have negative effects on the profitability of farm production as well as the productivity of agricultural resources in the areas affected by its production activities. Hence, the study suggests that the relevant government agency, Federal Environmental Protection Agency (FEPA), should (i) ensure that the company compensates the affected farmers for the damages suffered and (ii) review the maximum permissible dust and noise emission levels in order to reduce the adverse effects of cement production in the study area.

“…This rapid industrialization has not been matched with proper planning for the control of environmental pollution problems that are usually associated with such industrial development (Adejumo et al, 1994;Owoade et al, 2013). Severe air pollution has been identified in overcrowded cities such as Lagos, Port Harcourt, Kaduna, Kano, and Abuja (Ifeanyichukwu, 2002).…”

This study was conducted to investigate the sources of fine and coarse airborne particulate matter in an urban environment in Nigeria. A total of 278 samples were collected over a twelve-month period from two industrial areas (Kudenda agricultural processing AP and Refinery industries NNPC) in Kaduna, Northern Nigeria for PM 2.5 and PM 2.5-10 on nuclepore polycarbonate filters using a Gent sampler. Elemental concentrations and black carbon analyses were performed using X-Ray fluorescence (XRF) and optical transmissometry respectively. The annual average concentrations for PM 2.5 at each site (Kudenda and NNPC) were 135.7 µg m -3 and 37.2 µg m -3 and for PM 2.5-10 , concentrations were 269.2 µg m -3 and 97.4 µg m -3 , respectively. These values exceeded the Nigerian Annual National Ambient Air Quality Standard (NAAQS) of 15 µg m -3 for PM 2.5 and 60 µg m -3 for PM 10 . Positive matrix factorization (PMF) was used to identify sources and quantify their contribution to pollutants at the sampling sites in one of the most industrialized cities in Nigeria. Four sources were resolved for both PM 2.5 and PM 2.5-10 and were identified as: Residual oil 49% (17.16 ± 0.04 µg m -3 ), Soil 29% (10.36 ± 0.26 µg m -3 ), Continental dust 18% (6.20 ± 0.18 µg m -3 ), and Motor vehicles emissions 4% (1.56 ± 0.02 µg m -3 ) for PM 2.5 while that for PM 2.5-10 were Soil 50% (27.37 ± 1.03 µg m -3 ), Continental dust 21% (11.55 ± 0.26 µg m -3 ), Vehicular emissions 18% (9.87 ± 0.03 µg m -3 ), and Petrochemical 11% (6.23 ± 0.02 µg m -3 ). About 82% and 79% were attributed to anthropogenic sources for both fine and coarse samples, respectively. Continental dust was associated with northwesterly and northerly regional transport. Residual oil combustion was the predominant fine PM source and was attributed to fuel oil combustion for power generation and process energy within the local industrial areas. Although transported continental dust is an important source, the majority of the airborne PM in this industrial area was the result of local emissions.

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.
