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.
本研究对尼日利亚人为空气排放的来源和大气水平进行了综述，旨在审视旨在缓解持续增长的国家协调机制是否存在。根据个别研究人员的报告，目前尼日利亚人为空气污染物的大气负荷正以惊人的速度增长。更大的担忧基于现有排放清单的不足、持续评估、政治意愿以及有效减轻这些污染物的政策计划的制定。这些排放的已确定关键驱动因素包括天然气燃烧、石油产品精炼、发电用热电厂、交通运输、制造业、土地利用变化、中小企业激增、医疗废物焚烧、城市垃圾处理、家庭烹饪、丛林燃烧以及土地耕种和畜牧等农业活动。在确定了人为空气排放的关键来源并通过汇总文献报告确定了其大气水平的上升之后，本研究呼吁对能源政策进行审查，采用空气排放和固体废物管理以及农业和土地利用模式方面的最佳做法，这些似乎是所有已确定排放源的共同关注点。该研究得出结论，采用清洁能源政策以及能源生产和使用方面的举措，而非一味追求热电厂并严重依赖化石燃料，将有助于减轻这些污染物的大气负荷。
