Abstract:This study aims at determining the impact of uncontrolled criteria air pollutants on air quality. The research estimates the emissions of criteria air pollutants from existing and proposed cement production facilities using the emission factor approach. The emissions from the existing plants for particulate matter (PM), sulfur dioxide (SO 2 ), oxides of nitrogen (NO x ), carbon dioxide (CO 2 ), and lead ranged between 0.031 and 354,240 tons per annum; 9.07 and 31,953.6 tons per annum; 5.04 and 17,750 tons per … Show more
“…Uncontrolled annual emissions from existing cement factories were estimated to be 1,604, 201 tons, 1,495 ton, 78,651.31 tons, 4,218.32 tons and 1,294.5 for PM, CO, SO 2 , NOx and Pb, respectively. These are expected to increase with the addition of proposed cement factories ( Oki et al., 2019 ). On a general note, the availability of emission inventories of air pollutants from other manufacturing industries could provide holistic understanding of their contributions to the country's airshed; although, a World Bank report put their 2007 value as 1.5 MMtCO 2 , 1.4 SO 2 kt, 29.3 ktNO x, 0.8 ktBC and 0.9 ktOC per annum ( World Bank, 2014 ).…”

This study presents a review of sources and atmospheric levels of anthropogenic air emissions in Nigeria with a view to reviewing the existence or otherwise of national coordination aimed at mitigating the continued increase. According to individual researcher's reports, the atmospheric loading of anthropogenic air pollutants is currently on an alarming increase in Nigeria. Greater concerns are premised on the inadequacy existing emission inventories, continuous assessment, political will and development of policy plans for effective mitigation of these pollutants. The identified key drivers of these emissions include gas flaring, petroleum product refining, thermal plants for electricity generation, transportation, manufacturing sector, land use changes, proliferation of small and medium enterprises, medical wastes incineration, municipal waste disposal, domestic cooking, bush burning and agricultural activities such as land cultivation and animal rearing. Having identified the key sources of anthropogenic air emissions and established the rise in their atmospheric levels through aggregation of literature reports, this study calls for a review of energy policy, adoption of best practices in the management air emissions and solid wastes as well as agriculture and land use pattern which appear to be the rallying points of all identified sources of emission. The study concluded that the adoption of cleaner energy policies and initiatives in energy generation and usage as against pursuit of thermal plants and heavy dependence on fossil fuels will assist to ameliorate the atmospheric loadings of these pollutants.
